Conundrum 65: Taxi Driver Braking Style

The burning issue that has been exercising my mind for the past few hours is the way in which taxi drivers apply brakes to their cars. Thus I give you another entry as part of an occasional series, briefly noted...

So. Why do taxi drivers brake the way they do? What accounts for their peculiar relationship with their car's braking system? Why is that taxi drivers never want to idle their cars? And so forth...

zebras and kitsch


When a cab driver sees a red light, she will do one of two things:
  1. Accelerate and simply speed through the light - daring oncoming traffic in a game of chicken.
    This behaviour is almost de rigeur if you want to obtain a taxicab medallion - an initiation rite of sorts. When your car is branded as a taxi, it is a signifier, almost a warning signal of recklessness to other drivers, and you can trade on this reputation to bully through most intersections. Such are the fringe benefits of every profession.
  2. Slow to a stop at the light if it is obvious that one can't beat the light.
    In this scenario, you'll almost see the subliminal scowl on the driver's face in the mirror and the accompanying sound of disgust under their breath.
It is the manner in which taxi drivers slow to a stop that is the source of today's conundrum.

A taxi driver never simply slows down to a stop like other drivers. There's an eccentricity to the gradual manner in which they apply their brakes. It's a little hard to describe exactly how they brake but it is different enough that I always notice it; let's simply posit for our purposes a Brake Eccentricity Index ™ and assign taxi drivers the maximum value, 10, on an admittedly arbitrary 10 point scale. Still, why do they brake in such an unnatural fashion?

Theory 1: Maximize the fare


I should be a little bit more precise about this, namely that I've mostly observed eccentric braking styles in cities that have metered fares for taxis. Of course correlation is not causation but I've always thought that it was the fact that meter fares are lower when the taxi is idle than when it is moving that drove taxi drivers to this behaviour.

The notion here is that by keeping the taxi moving for as long as possible you will reap fiscal rewards. Amortized over the length of a typical shift, perhaps you can sneak in an extra hour of fares at the higher, mobile rate. If you consider driving a taxi as a purely revenue maximization enterprise then the optimal economic strategy is all about minimizing engine idle time and maximizing the amount of time the car is moving. The braking style then is simply a matter of arbitrage; 5-10% extra revenue will be nothing to sneeze at (handwaving at the exact amount).

One piece of the puzzle however is that I sometimes observe as much even in countries where taxi rides are not metered transactions. What gives?

Some control experiments: presumably there should be increased eccentricity in braking style the larger the difference between moving and idle fares. Drivers in cities with greater idle premiums would exhibit a higher brake eccentricity. Anecdotally New York and Boston are more prone to the phenomenon than San Francisco.

The web being what it is, an armchair economist such as myself can validate such intuition...

Consider this table taken from the San Francisco Taxicab Industry Report 2006 via the invaluable Taxi Library site. It is a survey of rates charged in various US cities.

taxicab rates 2006


We'll codify a proxy for our braking eccentricity quotient as the ratio of mileage rate to waiting time rate. In New York, this ratio is 10 (mileage rate per mile is $2.00 and waiting time per minute is $0.20). In San Francisco, the ratio is 5 (mileage rate per mile is $2.25 and waiting time per minute is $0.45). This would confirm the greater propensity of New York cabbies to work the brakes and even assign them 10 on our admittedly arbitrary index.

Out of interest, we have the following results: Chicago at 5.45, Houston at 5.67, Los Angeles at 5.5, Oakland at 6, San Jose at 5.95. In my experience, Oakland taxi drivers are more eccentric than San Francisco cabbies so this seems to be about right. The rate structure of fares provides serious incentives to taxi drivers to do everything possible to keep in motion, it is no wonder that they are irritated at having to wait, idle time literally robs them of revenue.

Theory 2a: Minimize fuel consumption and/or 2b. minimize wear on the car's brakes


Part of the utility function that a taxi driver has to account for is the impact of fuel consumption. With conventional internal combustion engines, the fuel that is used when the engine is idle is pure waste, hence it makes sense to minimize fuel consumption as part of the profit maximization function.

Wear and tear on the brakes is also something drivers need to worry about; perhaps it is indeed easier on the brakes to slow down the way they do. No one tells you that when you learn how to drive so this might well be a trade secret of sorts.

This last theory is counterbalanced by the frantic way brakes are applied when the driver misjudges and almost causes an accident (all too frequently judging by the statistics of road accidents involving taxis). Frequent near misses and even accidents are almost a cost of doing this kind of business and in those cases, brakes are manhandled. So a question for auto engineers, what is the best way to apply brakes? Incidentally I wonder if there is any research on the incidence of heart attacks amongst taxi drivers, but I digress...

Some control experiments:
  • hybrid cars are slowly being adopted into taxis fleets, these are cars in which the cost of idling has essentially been eliminated. Minimizing fuel consumption in one's Prius is thus a matter of running for as long as possible on electricity rather than on the conventional gasoline engine. Presumably Prius taxi drivers would not be as prone to brake eccentricity and the new technology might provide an insight into the relative importance of the fuel consumption factor. One should monitor the situation as hybrid adoption rates increase.
  • rising petrol prices should increase the fuel consumption premium so there should be increased eccentricity when we have higher prices. Metered fares after all aren't indexed to petrol prices and are only updated episodically. Anecdotally again, I've been noticing more braking shenanigans during the Bush years with the concomitant high oil prices.
With this in mind, perhaps we can add some additional dampening factors to our braking eccentricity index. I welcome your mathematical input.

Exegesis


The obvious thing to resolve this conundrum is to simply ask taxi drivers why indeed they brake the way they do. The thing is that whenever I've observed this behaviour, I've typically been annoyed because I tend to lean towards the first theory, namely that the driver is engaged in an attempt to wring an extra dollar or so out of my inconsiderable wallet. With that at the back of my mind, it will come off adversarial to ask the driver about this, no matter how academic the concern is. Also you might change the behaviour merely by asking and make the driver self-conscious. Moreover, there's always something more pressing to talk about: politics, the economy, real estate, cars, relationships etc. In any case, small things like taxi driver braking styles are appropriate fodder for blog entries. I hope I've made a plausible economic case of cabbies being rational economic actors but of course I may be missing the plot. Perhaps others can come up with better analyses. The floor is yours...

On Metering and Automation


Now you might well wonder why indeed I'm spending time and virtual ink on this matter. Well it is in aid of a book of toli. The low end theory posits that one should temper the human factor to encourage adoption. Thus I've been digging around matters of human factors and automation. The obvious case study of the human factor in technology adoption is with taxis and the introduction of metered fares. A little digression and that's all she wrote.

The idea of meters, of standard fares introduced through regulation, meshes with an attempt to eliminate the vagaries of human discretion and bargaining around the negotiation of payment for rides. Prior to their introduction, one was at the mercy of one's skill and knowledge of prevailing rates when discussing fees with cab drivers, and often one would be at a considerable disadvantage in the conversation. The drive towards standardization and automation was almost inevitable in many communities; electronic meters were the technical solution to the legal and cultural problem. By metering you could reduce the amount of price discrimination that taxi drivers could do and gain some amount of consumer satisfaction at not having to bear the mental transaction costs.

Recently also there has been the introduction of GPS-driven radio dispatch into the taxi business in. One virtue is that this might prevent certain dispatchers from rewarding their favourites with the best jobs. I know that in the Boston area, Haitian cab drivers would always curse the often 'native' dispatchers, claiming that they wouldn't give them (the immigrants) jobs even if they were closer to the customers. Presumably technology in the form of location-aware optimization algorithms could add a measure of impartiality to the dispatching process along (potentially) with some extra efficiency. Of course as with all things in which the human factor applies this is not the end of the story. Wherever there is human discretion we will see the usual social and cultural cues and biases assert themselves in one form or another. For one, it all depends on what is coded and who gets to make the decision.

Indeed New York city taxi drivers will be going on strike against GPS devices in coming days:
The Taxi Workers Alliance opposes the installation of high-tech touch-screen video systems that will allow passengers to watch television, make credit-card payments and — using a global-positioning device that tracks the cab - follow their ride on an electronic map.

Some drivers have said that the global-positioning devices and the automated trip recording system are an invasion of privacy, and that the use of credit cards would diminish drivers' incomes, given the card transaction fees.

They also say they will take in less money because the system requires drivers to log on before each fare, and they object to the television noise and the heat from the monitors.
This last case is interesting in the bundling of two technologies, electronic payment systems and location aware devices. In both arenas, the proponents highlight the benefits in terms of consumer convenience: additional payment options and additional information (map data) that can empower the rider in the transaction with the driver. For example, a tourist, able to see a realtime map of their journey, will now be more liable to ask "Why the hell are you going in this roundabout way to my hotel?" and reduce the unscrupulousness of drivers.

Detractors similarly highlight the effects of payments and transaction costs. By introducting credit cards into the billing systems, the authorities are passing on increased costs to drivers, a tax of sorts. A slight digression here: the taxi profession has typically been a cash-is-king affair - hence for example its appeal for the informal sector often the domain of transients and immigrants etc. (e.g. for an extreme case of 'informality' you can read James Ellroy's novels on the appeal of taxi ranks for the Mafia).

Both sides of the debate conflate things. Who really wants to watch television in a cab? That is surely a byword for yet more advertising. And yet that is what Mayor Bloomberg is touting even as the agenda of the authorities is plainly to exert additional control on the profession. On the one hand, the argument about privacy that the drivers advance is probably not the core objection, it is rather the issue of control, about losing discretion in the way they do business and the burden of additional transaction costs (which can even be mental costs).

A few centuries ago, the Quakers brought sanity to the systems of measurement with their reputation for probity in the standards of weights they provided. Eventually, social norms and mores were codified in laws, regulations and sometimes in technological standards. It is interesting that we are seeing lawmakers seeking to impose technological standards to achieve social ends. As we have seen in the case of braking style, there will still be behavioural attempts to game the system — that is the realm of the human factor. In the low end theory framework, the best you can hope for is to temper these things.

This year in Accra, the Accra Metropolitan Authority introduced medallions for taxi cabs and even imposed a dress code on taxi drivers (although from what I understand, the dress code is not that widely adopted). The introduction incidentally lead to an immediate decrease in the typical crime methods where criminals would use cabs for their robberies. By getting control of licensing, the AMA has managed to better understand the scope of the taxi market, the public also can better identify taxis and further norms can be codified. One wonders whether metered fares will be the next regulation to be adopted in Ghana. As anyone would tell you, a large part of the experience of using public transit in Ghana is the bargaining that one must do. Taxi drivers will quote exorbitant fares to those they perceive as well-heeled or unaware of the prevailing rates - and you don't even need to be an obroni to feel cheated at times. Metered fares would have undoubted benefits in reducing this kind of price discrimination and the associated transaction costs but might also remove social and cultural lubricants, those aspects of conversation and market traditions. I wonder if this is a trade-off that should be made. What say you?

I'll close with a further digression... You might have seen me point to this Lion King decorated taxi a couple of weeks ago. The Wife caught it parked next to the zebras and kitsch taxi displayed above. I quite like the serendipity of the photos and the varying images of Africa expressed in taxicabs.

Lion Kings and Zebras and Kitsch, Viewing Africa in London


Abercrombie & Kent are merchants of "Inspiring Experiences of Namibia" hence the zebras crossing they use to advertise their escapist travel services. The Lion King of course is pure Disney nostalgia. Such are the types and faces we use on our taxis about Africa that mysterious land. The fantasy of Brand Africa.

A Taxi Driver Soundtrack


  • Loose Ends - Slow Down
    Apropos braking, we'll start our playlist with Slow Down, the brilliant showpiece of Loose Ends' Zagora album. Classic 80s soul music, eminently danceable and with an infectious chorus. It is often paired with the lead single Stay A Little While Child and the titles are fitting for the laidback theme of the band.
  • The La Drivers Union Por Por Group - Trotro Tour Of Ghana

    The La Drivers Union Por Por Group - Por Por: Honk Horn Music of Ghana

    We'll continue with some music by taxi drivers, some honk horn music from Ghana. It's unlike almost anything you've heard, simply consisting of the horns and drums that you might here on the streets as these drivers vie for your trade and seek to attract your attention. This horn group has a 50 year history amongst other things, wielding their honk horns against the colonial regime. They continue to make music from the most unlikely of instuments.

    I quite like 'Driver, Take Me, The Train Has Left Me Behind' and the Kpanlogo Por Por Medley but perhaps it is "Trotro Drivers, We Love You So" that is the best song on the album. You can listen to the slightly more conventional yet still exuberant Trotro Tour of Ghana here for the next week.

Home Economics

The Wife and I have been thinking of buying a house for the past year and, since spring, have been mostly bemused at the huhudious prices that were being quoted to us (with straight faces, mind you) for mostly depression era houses. Thus we've been getting an education on the hard sell during our few months of attending open houses, and also some lessons in home economics.

follies


The New Mathematics


After last week's action, some new mathematics is in effect. We have the following equation:

Maximum prudent ™ house price = $521,250 = $417,000 (maximum federally-insured mortgage) + 20% downpayment

Note: prudent ™ denotes a conforming loan and home financing deal that wouldn't raise the eyebrows of even the staidest banker.

Note: the days of 20 percent downpayment have been out of fashion for a long time (we live in a subprime era) so we'll relax our stringent banker conservatism and use a 10 percent downpayment as our baseline. This reduces the maximum prudent house price to $463,333.

Note: the conforming loan limit of $417,000 is the maximum federally-insured mortgage above which point we are in the realm of jumbo mortgages which have all of a sudden become quite scarce.

Voodoo Economics


The median price of housing listed in the Bay Area was said to be $785,380 in February 2007 when we started looking in earnest. That was the listing price and not necessarily the sale price but, regardless, that was sticker shock by any definition.

In June 2007, the median housing price paid in the Bay Area was $665,000, a new peak. See also a trend graph of an earlier data set.

The typical monthly mortgage payment in the Bay Area was $3,219. "adjusted for inflation, current payments are 24.0 percent above typical payments in the spring of 1989, the peak of the prior real estate cycle." Jumbo mortgages "represented 62 percent of the purchase loans" made in the area.

taos pueblo


Jumbo Jitters


Putting these things together, it is clear that something does not compute. The force of gravity will make itself felt and the $200,000 gap - the fat on which the housing sector in the Bay Area has been feasting on for the past 15 years - will of necessity be closed. The only questions are how much the gap will narrow and how long it will take.

The typical price of the only reasonable houses we have seen during our search was $750,000 (The Wife has called much of the rogues gallery that were shown to us "illegal dwellings"). We thought we'd seen an overheated market in Boston but the Bay Area has redefined our perceptions on that front. A software engineer and history professor ought to be able to afford a starter house.

The hard sell and the real estate shell game was in earnest and it was as if the whole town was in on the con. The pinnacle was the university housing officer who advised her academic client that we could easily afford a $700-800,000 mortgage - if you ran the numbers, monthly housing payments (circa $5,000) would far exceed the salaries of most academics which prompted said academic's quip "I'm not going to spend that much on a depression era bungalow" to the surprisingly-shocked agent. I suppose I would have put it as the Emperor has no teeth.

Even if we could afford such imprudent things we'd rather spend our money traveling to more congenial settings, we are modern travelers and exiled souls after all. The funny thing is that if you spend enough time talking about housing in the Bay Area, you could almost convince yourself that everything was normal. Nobody blinked in conversation; the stratospheric prices were just the way things were — indeed it was so surreal and you could very easily allow yourself to be bamboozled — there was a week where we almost succumbed. Almost...

modest


There's lots of moral hazard in the mounting chorus to bail out the fiscal wizards. Many are lobbying for the limits on Fannie Mae and the like to be lifted or for interest rates to be cut. Sidenote: the language of financial panics is always interesting: credit crunch, mortgage meltdowns, debacles etc. Fed chairman Ben Bernanke has been known for his "cautious experiments" in the past and will surely come up with some kind of intervention. When well-heeled bankers start invoking the spectre of millions out on the street you can almost hear the subliminal "think about the children" message. John Kenneth Galbraith is sorely missed.

In any case, we continue to search for a home... For the first time last week, we saw advertised a condo in a nice neighbourhood that was priced under the new mathematics at $469,000 - some sellers obviously need to cash out quickly (similar houses were priced at $650,000 just a few months ago). Hopefully we'll start seeing more of these things and it might even become a buyer's market. I won't hold my breath however; there's a surplus of unreality in the Bay Area.

no hurry


In closing I'll note that Ikea was packed last weekend — everybody is doing home improvement, it seems. I don't think much of it was about putting a shine on show houses that you needed to flip ("one last try"), rather I suspect that it was belt-tightening at work, and making do with what you have. Time will tell and we'll be waiting this one out in our rented nest.

A Subprime Playlist


Some music for those inclined to home economics...
  • Dionne Warwick - A House Is Not A Home
    Dionne really came into her own when she sang the Burt Baccarach songbook. It was a sublime case of pathos, operatic pop as it were featuring Baccarach's lyricism distilled in that delicate voice. All her later monetary triumphs stemmed from the magic of those wonderful interpretations.
  • Kool Moe Dee - They Want Money
    I was going to pick Money Jungle by Duke Ellington, Charlie Mingus and Max Roach for this playlist - the song (and album) is suitably jarring and tense, but I thought that Kool Moe Dee would be more appropriate. The title of the album is a key indicator: Knowledge is King. Laymen are always the last to get bailouts hence education is key to prepare for the periodic shocks of the grifter impulse. They Want Money is the soundtrack for Jim Cramer's crew, its blaring horns an ode to Alan Greenspan's politically expedient teaser rates, its rapid-fire lyrics are dedicated, with respect, to all those who have been selling a bill of irresponsible goods in the housing market.
  • Simply Red - Money's Too Tight To Mention
    Social commentary of hard times and explicit lyrical harkening to Reaganomics. Mick Hucknell saw the darker side of trickle down economics and told it like it was. There are of course thousands of "no money" blues but when rendered in this pop vein, never have they been so upbeat or danceable. Perhaps one should also mention here Money to Burn by Wrinkars Experience in the reggae vein and round things off with the Wu-Tang Clan's C.R.E.A.M. ("Cash rules everything around me, cream get the money, dollar, dollar bill y'all")
  • Luther Vandross - A House Is Not A Home
    I really need to do an appreciation piece on Luther who, like Aretha, had the uncanny ability to make any song his own. Simply put, his version is the definitive version - it's not even close. Soul music with all the accoutrements, lush and emotional.
A house is not a home, how true.

On IBM and Africa

So IBM has launched an initiative on innovation and economic development in Africa. Presumably this is a prelude to a potential return to the continent twenty or so years after bailing out. One hopes the results of this brainstorming exercise are reasonable and enough interest is garnered. I even entered a few gnomic bullet points into the 'ThinkPlace' that aggregates ideas on the topic.

I have been asked by many in recent weeks what I think of the matter. Normally I tend to ignore Grand Initiatives ™ since I firmly believe in small things. In this case however, there is is a pleasing intersection with my declared interests: I am an African working at IBM and very publicly concerned with technology, Africa, cultural exchange and development issues.

There are lots of Africans at IBM, and lots of IBMers interested in Africa; the company however has been missing-in-action when it comes to the place. I suppose part of it is that the Africa constituency at IBM has been so diffuse. We are all heads down, minding our business and getting on with things - a head nod or two in corridors or names recognized on email threads. It's also been hard to figure out where and how to start the conversation. As a case in point, I started an Africa 'community' on our intranet just a week ago - apparently the first. When I searched our forums, "Community Central" and the Lotus Connections community portal, I couldn't find any such thing. But such is life, our dark matter warps the world in our quiet and informal way. Even better, there's now a forum and opportunity for such things to coalesce. Baby steps.

So: innovation and economic development in Africa. To my mind it's a matter of technology adoption, systems design and infrastructure with some attention to social and cultural factors. I thought the least I could do was share my jaundiced perspective, and give a little historical analysis of the scene. Herewith some unfiltered toli on IBM and Africa.

Busy Internet

The Great Game


There must be something in the air, Africa is very much in the news - the last such frisson d'Afrique was at the end of the Cold War, the democratic thaw and tightening of military budgets opened things up for a brief interlude. The signs have been there in recent years. In the technology world we have HP and Microsoft with their own initiatives. We also hear of the web companies like Google getting into the education market in Africa. In recent years IBM has turned towards the bottom of the pyramid, moving towards the BRICs (Brazil, Russia, India and China) and the low end.

Like everyone we're in search of growth and new streams of income. As the oft-quoted 'quip' from Willie Sutton goes, when asked why he robbed banks the response was "because that's were the money is at". In this same vein, Africa it appears, is the new scene of The Great Game, a game moreover playing itself out in politics, economics and now in the technology sphere. Great Games, I've noted, are all about cultural interplay. Technology adoption, which is what concerns a company like IBM on the whole, is not immune to interplay.

There must be black gold at the bottom of the pyramid - and, well, Africa is at present (and sadly so) that proverbial fundament. Thus there are opportunities but also pitfalls. If those on the ground in Africa are wise, they will be picking and chosing with care because, as befits the inexorable march of capital, the hard sell is on the way.

I'll casually stipulate that social implications and cultural sensitivity will be at a premium going forward. If everything is local, should you have an "Africa strategy" or do you need nuance, a regional focus and have to adjust to each country accordingly? How mature are the economies in question? Some countries are emerging from civil war and worse or even engaging in, pace Sudan. Is it a case of "South Africa, Nigeria and The Rest" like the World Bank (pdf) and UN economic reports would have it?

The more reflective will also want to ask: why all those years of benign neglect? And what are the implications of this renewed focus? IBM is cheerfully upfront about the motivations behind its initiative - "this is about business development, not charity", we're in the realm of hardnosed pragmatism - the capitalist sort. Still, if we move beyond rhetoric, is a partnership with Africa being sought? Is it a conversation? Will it be a fickle commitment? Are we seeking monopoly rents or to dictate to pliant new markets? Or are we rather intending to muddy the waters for other players, spoiling the game?

As you can see, there are lots of questions to ask. Also, you've no doubt noted that when I use the word 'we', I oscillate between Africans and IBM - confusion all around...

In history the race to Fashoda is said to have precipitated the great Scramble for Africa, with effects that reverberated in the colonial era. Indeed some suggest that it is still ongoing. One wonders whether future historians of technology will view such initiatives as similar precipitating events.

Personal History


I have very fond memories of IBM typewriters, some have suggested that this is why I ended working for IBM in later life. That is a red herring: I was recruited and hired by Lotus, but IBM took over the company between my acceptance of Lotus' offer letter and my start date. I thought I would be working for relatively young upstarts in the software industry, instead I came to be employed by IBM. I was thus one of the first to experience that typical confusion that reigns when companies do mergers and acquisitions and try to adjust and integrate processes. My first few months were a kind of gruesome initiation ritual, summary abandonment in the swampland of Human Resources on Merger Island.

Sidenote: human resources - there's a phrase you never want to hear. If you ever find yourself wondering how to get in contact with the human resources department, you are in a very bad way. Such departments are long-suffering and indeed helpful at their best, but their very appearance in your mental landscape is ominous — a sign of the Apocalypse perhaps. I should know. But I digress...

More apt is that my first 'real' work experience was a summer stint circa 1992 working for the IBM dealers in Ghana; their name: Masai Computers. Thus I have some personal experience with the evolution of IBM in Africa and can supply a case study.

IBM had pulled out of Ghana and most African countries, bar South Africa, a few years earlier, and dealt with the continent through a network of local business partners. Beyond the occasional big government deal where one would need to call in the heavy duty consultants, Big Blue has essentially been away from the continent since the late 70s and early 80s.

This is fair I suppose, broadly speaking there wasn't much economic activity or investment in technology and infrastructure between 1970 and say 1993. Handwaving a little, and with some amount of hindsight, we can say that if you were a prudent Chief Financial Officer of a large technology company, you might as well have sat out that period. Heck there was regression in the economies of a sizable cohort of countries. Other than a few holdouts like Botswana, there wasn't much to cheer. Certainly Africans weren't cheering. Sidenote: the conventional wisdom per Meredith and others is that the 80s were "the lost decade".

On the other hand, some made lots of money in Africa during this period. The French, for example, never stepped away from the continent and they maintained their spheres of influence; their political system demands an outlet for easy money, and getting money from Francophone Africa has been easy, if a little messy at times. By and large however, Big Oil, Big Military, Big Cold War and Big Rogues had the field to themselves. Big Pharmaceuticals, like Big Agriculture, kept a foot in the game but were disinterested players on the whole. Big Technology, with the notable exception of the slow and steady Big Telecom, was not interested in Africa.

The population grew. Africa has one of the youngest populations in the world and labour costs are cheap (although not rock bottom like say Bangladesh, Vietnam and the like). Presumably the dynamism of this surplus can be harnessed - modulo education, literacy and supporting infrastructure.

High St - Accra


But back to technology... If your core business was software, hardware and consulting services, there wasn't much joy, after all a service industry requires the existence of things to service. What growth there was between the 1970s and 1990s rode the disruption of personal computers and their accoutrements. So: the printer business was as lucrative as elsewhere (ergo HP always maintained a presence). Communication also was a slow but steady business - for phone networks, the emphasis was on a slow roll out.

All this to say that during my months at Masai, my experience was in dealing with the spread of personal computers. The focus was on hardware with only the occasional software intervention. I dealt, on the whole, with small businesses that needed a little handholding. Significant also was the government work - the banks and mining companies too were a reliable source of business.

Technology adoption was thus a matter of gaining familiarity with office productivity tools. In the background, email and groupware were beginning to be deployed as the lure of networks was rearing its head. I also dealt with a few financial and accounting jobs - harassed office managers were greatful for my visits and tutorials - one offered me a bag of rice for my troubles.

There was a little dissonance on my part: there I was getting an electrical engineering education - with a little side angle on software, and yet the only skills that were applicable were of the technician variety. "We just need to vacuum the inside of your computer, Kwabena". "Yeah the air-conditioner isn't working, it gets dusty, Afua". "Oh Ama, the printer cable was unplugged". I'd walk around vaguely unsatisfied at the level of challenge I was facing. It was chastening but instructive and caused me to revisit my assumptions about how one could contribute. Until basic infrastructure is in place and redundancy is ubiquitous, one will have to lower one's expectations.

Funnily enough it was the social factors that were most challenging. The folks who can handle Excel and such are the critical audience, for they just want slightly better tools to help them work more effectively without having to refer to the IT department - if indeed they have the luxury of such a beast. How could one empower a little department? How does one get collaboration in distributed environments with unreliable and intermittent connectivity? A focus on the interpersonal and social was the answer.

I loved to watch how power flowed in these organizations and spent time trying to figure out who really ran the place. Ownership and familiarity with computers would give some people almost magical powers. At the same time others, the ones who actually seemed to be getting things done, had little patience for these computer things. Thus games of authority, reputation and knowledge played themselves out. What were the incentives for asserting one's knowledge and expertise given a dysfunctional polity of arbitrary military rule as a background. If you became known as an authority, would that expose you to risk courtesy of The Authorities? And could others jump their station simply by knowing the right people?

In any case, these observations served me well as precursors to the focus on collaboration that I later saw when I joined Lotus. The challenge of capturing the rigours of a constrained environment and organizational behaviour writ large.

IBM, Compaq and HP were then dominant in the local PC industry although Dell was beginning its ascendancy. I was surprised at the potency of Packard Bell in the market given their reliability issues (issues that would later doom them). In Ghana they appeared to have a major presence presumably because of their pricing for the low end. One was beginning to see the Taiwanese and white box manufacturers play their cards and also take root - they are now the main game in town. The second hand market was also a major factor, discarded or recycled computers from the West gained new life in our hands.

I spent a fair amount of time simply fixing printers. HP at the time was in a minor slump and weren't loved, although their printers were in widespread use since "that was what the bosses ordered". In contrast, Canon printers and faxes were cheap, reliable and, crucially, suitably rugged for the tropical environment. Which leads me to another observation and a sentence I frequently spoke: "Kofi, we need to order another stabilizer and surge protector".

Power capacity and reliability were a major concern - they continue to be, witness the load shedding exercises in the past year in Ghana. The operating environment meant that software and hardware needed to be tropicalized because lights out was a frequent occurrence, and not everybody had backup power generators. The high-tech electronics that the modern world features can't handle the kind of surges and spikes we experienced daily. Thus there is an implicit energy tax when you work in some parts of Africa - your software and hardware should adjust accordingly.

Another sidenote: a little cottage industry was developing to tackle these power management issues - many of my colleagues were building custom power stabilizers and slightly tweaked software that, for example, saved to disk more frequently to recover more easily from power outages. They would make side arrangements to supply clients with these "tropicalized" hardware and software systems. Draw your own conclusions about company loyalty in an environment where it is every man for himself, or perhaps be gladdened by the initiative and entrepreneurial spirit that these unofficial consultancies implied.

One further leading indicator: malaria was wreaking its usual toll. This was the time of go-slow malaria: relapses every week for a month or more - fun times, right? A fair number of my colleagues had malaria at some point; you'd notice the sweaty palms and the occasional mid-afternoon slumping on their desks. One's first thought was that it was laziness, but a closer look would reveal the economic cost of the mosquito principle. There wasn't an office I'd visit that didn't have someone dealing with the disease, with the obvious deleterious effects on capacity and productivity.

Later Masai got into politics - sadly unavoidable given the vultures that were ruling us during the period. It was a simple cost of doing business in Ghana at that time: you had to contribute to that cabal of rogues. Indeed there was an enforced election in 1992 and those folks had to hand over to themselves... Like all small businesses in Ghana when confronted with offers you couldn't refuse (demands for kickbacks and more), Masai 'diversified' and got into 'buying and selling' - and with gusto. Thus there was a turn to such things as importing cars, televisions, stereos and even kitchen equipment (Masai pots and pans!) from Taiwan, Singapore, Malaysia and the like. Increasingly as the nineties progressed, China became the supplier of choice. The core business persisted but ultimately it was neglected.

Thus it was that Ghanaian businesses amounted to buy-and-sell in the eighties and well into the nineties, largely as a reaction to misrule. Scrutinize the majority of companies and you won't find many cases of resources or capital being plowed back into the core business. Investment and growth faltered accordingly. The computer services industry was not big enough; there was nothing to service.

Melkom poster


It was a fun summer and, in the 15 years since, I've followed the evolution of the technology industry in Ghana with keen interest. Masai and others went by the wayside, hollowed, as it were, from the inside. The restless types eager to escape their constraints saw the opportunities coming. The internet loomed and they made their move. Now there is a viable technology industry in the country. Big Capital is taking note.

Strategic Outlook


I offer these notes to give a sense of the complexity of dealing with technology adoption in Africa - the agony and the ecstasy as it were. Sometimes it is the small things that can blindside you. For example if malaria is a significant cost of doing business in Africa then perhaps, your first investment should be in mosquito nets for all your employees and their families (like some enlightened mining companies are now doing). Perhaps a focus on such side issues may provide the biggest bang for your investment dollars. Still I wouldn't extrapolate too much on the particulars I've raised. The Ghanaian experience, let alone my personal diasporan experience of it, can't possibly capture all of the African challenge.

More to the point, the terrain of the technology game in Africa has changed. As personal computers have continued their spread, there has been more use of software and there is now a market for such services - cash registers, payroll systems, inventory control and so forth - the guts of modern business infrastructure. The major change has been the ascendancy of networks - the internet, with its great popularizer, the web, and, of late, mobile telephony. This has lead to more interest in collaboration as distribution and coordination costs have been dramatically reduced. Also the costs of starting up internet-related business have vastly decreased and we have experience dealing with Moore's law in the network-enabled datacenter. You can even lease internet infrastructure if need be.

The Masai example however should give an idea of the challenges. Structurally, many businesses are undercapitalized and on the surface, disorganized. There are lots of good ideas, and indeed there is much entrepreneurship but when you come into the continent and partner up, you should know that your partners may not have the single-minded focus that you have. They are juggling constraints you can't imagine and have adapted their strategies and behaviour accordingly. Also keep in mind that sustaining investment will be like keeping up a good conversation - if you don't pay attention to your interlocutors, they, and Africa itself, will remain opaque. Nigeria is a case in point, its brand of capitalism is a cauldron of creative destruction. But if you can master it, well... they don't call it black gold for nothing.

The benign neglect of the 70s and 80s paradoxically left enough space open for small entrepreneurs to pick their niches. That is the way of capital. One currently hears lots of young lions growling, hungry after a decade or so of growth. Some outsiders seek high and quick rewards when investing in Africa, others opt for slow and steady income growth. Africa is a greenfield and strategies are many.

The MBA types are all about sizing the market, no one wants to invest on blind faith. Armed with a few statistics and Gartner predictions you can forge ahead or demur. There are lots of analysts and strategy consultants that cover this terrain, offering advice about investing in emerging markets for a fee of course. Some of the analysis is insightful and when I read, I search for nuance about the challenges: economic, structural, legal, political and social. Thus it has been interesting going over the many ideas posted to the ThinkPlace: a curious mixture of pie-in-the-sky and very focused pragmatism. My guess is that one will get as much from the exercise as any expensive McKinsey survey could provide.

I'll use this note then to suggest a few areas that could be scrutinized - free analysis courtesy of the toli.

construction materials


I've been slowly developing a low end theory of technology and I'll use its nascent framework to tease out a few strategic directions for the outsider investing in technology in Africa. To recap, the main tenets of The Low End Theory
  • identify and leverage disruptions in the system
  • Lower coordination costs through layer stripping
  • Favour participation over control
  • Temper the human factor to encourage adoption

Disruptions


The first step is to identify disruptions. I see four major disruptions in the technology arena:
  • personal computers
  • networks: the internet and the web
  • mobility
  • storage
Of these we can perhaps discount the workings of storage, that has been a second order disruption and emerging markets will be last to capitalize on it. At least that seems to be the trend.

One change from a the past is that IBM has opted out of the low end in the Great Game of Chips and sold its personal computer business. Thus it can't benefit from that ongoing disruption, which is only now working its way through emerging markets. The field in the personal computer ecosystem is open to those who kept their hand in the game. As I've suggested, in hardware we'll have the white box manufacturers, the Taiwan and China contingent (Lenovo, Acer etc) and the chipset and assembly folks, some of the big boys who never faltered (e.g. HP), the chip manufacturers (Intel, AMD and perhaps some of the DSP crew) and of course the software ecosystem (say Microsoft, Adobe and savvy Linux folks). For IBM, the focus on high-end servers and mainframes is fine (and certainly lucrative) but it narrows the disruptions that the company can leverage in the African market. Oh well, you can't win them all and hopefully the disruption of the spread of the internet and mobility opens a large enough investment field.

So: networks. The internet and IP based technologies are fostering great advances in communication (TCP/IP, VOIP, Ethernet, Wi-Fi etc.). Coupled with the web, we now have a great platform for distribution of software and services with the fringe benefits of collaboration, participation and group forming. The innovation that comes from these technologies is transforming everything in sight - witness the inexorable march of open source. Sidenote: I'm currently paid by IBM to contribute to the Dojo toolkit open source project, who would have thought it even a decade ago?

On mobility, the immediate focus is again on communication. Many in emerging markets are voting with their pocketbooks for mobility. Mobile phones, with accompanying SMS, and some of the new data services are the main draw. The architectural challenge here is how best to deal with intermittent connectivity and synchronization.

People are making great claims for mobile platforms and there are lots of interesting numbers about the uptake - I'll be discussing some in a later note. The obvious pitfall about mobility is that the current incumbents have the temptations of walled gardens and you often have to get permission from phone companies, handset manufacturers and network operators before you can deploy your Next Great Idea ®. You have to deal with these gatekeepers and share billing infrastructure and, most importantly, profits in whatever area (hardware, software or services).

The low end theory predicts that platforms that encourage participation over control will see greater adoption. Thus, even though mobility may be more exciting and sexy as an investment arena, mobile operators might well lose the plot. So long as you are susceptible to a priori negotiation with gatekeepers, generativity, as Zittrain would put it, will be constrained. This of course is all a clear reading of the End-to-End principle. In terms of strategy then, I suspect you'd be happier riding the voice over IP wave than the cell phone market in the current environment. Pay close attention to the actions of the gatekeepers in the mobility ecosystem. Sidenote: If you want some mathematics or economics to motivate this insight try Bradner and Gaynor - a real options metric to evaluate network, protocol, and service architecture (pdf) for example.

Directions


A brief survey of investment directions in technology in Africa.

Regional Economic Integration


Too many African economies are focused externally, whether in terms of being export-driven or importing from outside Africa and almost never regionally. This is part of the colonial legacy. Ultimately sustainability will come from being able to develop internal and regional markets. Opportunities here are in targeting government and regulatory systems. Not very exciting or with immediate payoff since politics are involved, but a reasonable investment opportunity.

Remittances


There's lots of room for increased lubrication of the system to harness the considerable diasporan contributions and to reduce the transaction fees. A business model backed with appropriate technology can wipe off the floor the monopoly rents that Western Union and company have been accruing. Of course there are regulatory and security concerns in this new age of terrorism but there is clearly a business model to be teased out, as with the banking sector. Consider the big fat target that was hit in Mexico where "the fee for remitting money has dropped from an average of 9.2% in 1999 to 3% in January 2007" - note that many are making huge profits even on 3% fees. A simple suggestion: look over Ben Hyde's shoulder and implement whatever he says (see pseudo Bank Accounts for the poor for example).

Banking


The banking industry is interesting and a known quantity to companies like IBM so it should receive lots of attention. In many countries in Africa, there is a large informal sector and the banks are often in furious competition with it - the susu collectors in Ghana for example. Informal they may be, the latter could stand to be automated and organized, if not brought into the formal sector.

In the USA for example, "a significant portion of urban consumers continue to be unbanked and under-banked" and these are often minorities. By analogy, the same broad strategies can be applied to African markets.

The application of technology in banking and the informal sector should be a no brainer, as is careful and efficient money management. Why leave the market to the equivalent of Western Union or payday loan sharks? You can even hedge your investments if need be. Thus I'd suggest that software and systems developed for banking services are a significant area of interest and profit.

Rapid Enterprise Anthill

Rural Strategizing


In many African countries a significant proportion of the population is often rural and engaged in agriculture. True there is the centuries-long trend of migration to urban areas with the resulting slums, and as a matter of policy most governments tend to prioritize the urban poor over the rural poor even in their constrained budgets.

An interesting challenge is how can one make technology work for the rural and agricultural sector. What are the services that can improve capacity and development? The immediate answer is communication and transportation to smooth the back and forth interactions with families, friends and customers in the city. With regards to agriculture, there are also things like better and more timely information about pricing, and the disintermediation that improved connectivity can provide. There's a business model in servicing the needs of rural communities, it's not sexy but I think it could be rewarding.

Infrastructure


Almost by definition the biggest need in developing countries is infrastructure. Infrastructure is much neglected, whether it is power, water, transportation, housing or education. These are persistent problems and here governments and businesses have their hands full. Such areas are mostly out of the comfort zone of big technology companies, hence I'll elide the analysis.

Network infrastructure, whether for mobility or the internet, is the clear target. Folks on the ground, constrained by costs and capital, are starting with open source software and commodity hardware when they build their internet services.

IBM has lots of expertise in building and running heavy duty infrastructure and might be able to compete in internet infrastructure game. IBM and Sun for example could be more flexible with pricing so that their higher-end hardware and operating systems could get consideration instead of Linux on commodity x86 hardware - the low end theory again. On software, folks will use PHP/Jetty/Tomcat instead of Websphere Application Server or BEA Weblogic, open source is the starting point for many (pdf). For companies like Microsoft and IBM, this is highly problematic, because an entire generation is starting up with the web or internet in mind and little familiarity with their toolchains. Linux and company are disruptive even on the basis of extending the lifespan of hardware that would be considered underpowered in the developed world.

Whether it is in datacenter hardware systems or software, infrastructure must be tropicalized to deal with unreliable power. As a design principle one will need a single-minded focus on power consumption and on resilient systems - perhaps IBM's mutterings on autonomous computing might have been prescient - the jury is still out. The problem space of intermittent connectivity and synchronization could also be explored. Wild speculation: the best solutions will come from the developing world since it is the daily bread of the environment.

Taxes


In the developed world, death and taxes are the only certainties. In the developing world, death is the only certainty. Taxes are avoided by virtue of a large informal sector. Again, taxation is not a sexy business and it is one where one deals with governments, regulation and compliance. Still, it is a sizable business and there are considerable inefficiencies in tax collection and assessment in Africa. Removing the human factor from the equation can and should be a lucrative business opportunity.

Markets


In West Africa at least, a lot of our cultural and social energies come from marketplaces. Small business, petty traders and such need organization and the pooling of capital for further investment and growth. Their needs are primarily communication (phones, VOIP), basic content management, accounting services etc. You'll see a lot of small businesses collaborating on complex projects along with the emergence of pockets of incubation. I'll simply suggest a business opportunity in services that target the aggregation of marketplaces and engages with the informal sector.

So-called intellectual property


A brief note on so-called intellectual property...

The great spurt of American capitalism, the one that laid the foundation for the current enduring prosperity occurred between 1820 and 1920. The later innovations of the modern corporation are all well and good, but we should not forget that the building blocks and the core infrastructure build-out occured in an environment in which America paid no attention to the intellectual property of others. At best, it was lip-service that was paid, and there was the requisite rhetoric in terms of the laws on the land. Enforcement was another question.

Patents, copyrights and such were important internally, but when it came to stealing the best of European and other innovations, there was no holding back. In polite language, there was liberal borrowing from others. But this is not a unique phenomenon, whether it was Japan, Taiwan, the eastern tigers in living memory, in matters of development, talk about so-called intellectual property are sideshows. Such talk is at best ignored until a critical mass of development has been achieved.

All this to suggest that you aren't going to get much sympathy with talk about so-called intellectual property in Africa. At a time when many African countries are barely emerging from biblical depths, and in a context when exploitation of the continent's resources has occurred for centuries, the attitude of Africans towards so-called intellectual property is rightly going to be disdainful. It's a fact of life, deal with it. Check back with us in a few decades.

Pricing Models - a thought experiment


Let's flesh out one of these areas more fully as an example.

I'll suggest a business model based on servicing flat rate pricing and/or prepaid, pay-as-you-go for a variety of goods and services. Initial targets are basic utilities like electricity and gas but many other services can be addressed.

Potential benefits: Provide predictable pricing and micro-financing for consumers. Fuller capacity utilization for producers and ease of planning for expansion.

Why: African consumers and small businesses on the whole are very price sensitive; many are under-capitalized. Business are undercapitalized, and consumers especially the urban poor and in the rural sector live a precarious existence from paycheck to paycheck. Thus their consumption of all manner of goods and services is predicated on predictable pricing, micro-financing and subject to the vagaries of exigency. Producers in these markets often enjoy considerable price discrimination but paradoxically often have excess capacity. Producers thus would like to stimulate demand to get full capacity utilization but have been stymied by their use of traditional pricing mechanisms.

This suggestion is based on a couple of observations
  • African consumers have voted with their wallets for mobile telephony even at the expense of fixed line telephony. The most popular arrangement in this uptake has been prepaid pay-as-you-go billing.
  • Even for things like electricity, if you could deliver the service with a prepaid card, you can get significant uptake. For example, small vendors in marketplaces will often pool resources together if need be in order to obtain vital communal service - sometimes these arrangements are informal. The same goes for other kinds of utilities.
Flat rate or pay-as-you go seem to be the key ingredients in that they provide predictable pricing and bite-sized micro-consumption that is amenable to better planning by both consumers and producers. These in combination are an effective way of marketing goods to the developing world.

One could offer producers packaging and billing services for their products that emphasize either pre-paid or flat-rate pricing. Provide infrastructure and billing services for all-you-can-use or bite-sized services. Many goods, whether it is electricity or call minutes, can be unbundled or packaged and delivered for flat rate or pre-paid increments. There are two aspects that are interesting businesses in and of themselves: the initial consulting services for businesses, the implementation of billing, un-bundling infrastructure, potential outsourcing of said infrastructure. Brand it if need be.

Do note that I'm deliberately doing some bundling of my own here, conflating, as I am, flat rate and pay-as-you-go. Anybody can do flat rate pricing and obviously you can use dynamic pricing with prepaid - as most calling cards tend to do. I think that these are complimentary approaches.

There are many obvious downsides and feasibility is in question but technology can help. I'll anecdotally note that electricity companies in Ghana have had an easier time of it, in their planning and in their utilization, by going to the urban areas and selling their services on this model in recent years.

A few other comments... Most companies see the billing relationship with customers as very crucial and will not want to outsource it. The conventional wisdom in customer relationship management 101 says never cede the ground to intermediaries. This limits the business opportunity here to consulting services.

Many companies want to retain more dynamic pricing mechanisms to better leverage price discrimination and they are unconvinced about flat rate pricing on the one and the prepaid model on the other. Nothing precludes anyone from having 'flex payments' alongside the flat rate or the prepaid options. Many businesses would like to be like to have the swagger of the old school airline companies with dynamic pricing and gouging of first and business class and even the casual traveler. Consumers, I'd note, seem to like flat rates whenever they are offered.

The products in question need to have utility for consumers to want them in the first place, that goes without saying. It seems that core things like transportation and communication are the proving grounds. Handwaving as usual, I'd argue that you can gain a competitive advantage in emerging markets - where most consumers by definition are price sensitive, by exploring these options. Oftentimes, businesses don't realize that these options are available, nor indeed that the technology to implement them exists and comes relatively cheaply.

Anyway this is just a thought experiment, caveat emptor, caveat lector and so forth.

observers are worried


Summing up


There are lots of opportunities in Africa. The competition will be fierce and one needs focused execution in markets that ride disruptions and commodities. When developing for the low end, ubiquity and leverage are everything and one's mindset should be adjusted accordingly. The interplay in coming decades will be undoubtedly be interesting.

There are encouraging trends but one also should seek some numbers to back them up and inform decisions. I've discussed here a view from the outside about strategies to go into Africa. What I find significantly more interesting is the reverse perspective. Are Africans brainstorming their own initiatives for engagement with the rest of the world? When you spot Big Capital coming your way, do you have your plans ready for them? Do you know what you want to use capital for? The question shouldn't solely be a matter of what you have to offer the world, it bears thinking about what you want to get from the rest of the world.

In conclusion, I feel a little like George Keenan writing my unsolicited Long Telegram home, although, with the changing medium, it has been a couple of hours of thinking aloud, furiously blogging away. In setting these thoughts down, it appears I have more open questions than answers. The main thing however is to enter in the global conversation and prod it in my favoured directions. Living as I do in the dark matter of technology, I'm minded of what the physicists say: dark matter surfaces occasionally.

Afro-Blue: A Soundtrack


As is my custom, I give you a short soundtrack for this note. As befits interplay there will be tracks both from within and without Africa. Dig the Africa playlist.
  • John Coltrane - Africa
    The big brass band, the two bass players getting busy, the saxophone doing its thing. It sounds a little like Olé except augmented with the big band. There is a little dissonance at first, it's a little unfamiliar, you wonder what is happening. The bass is thumping, the horns are shrieking, the drums have their solo. The folks at Breath of Life discussed Africa pointing out a few cover versions worth investigating: Dwight Tribe's version is angry, the SF Jazz Collective is urbane.

    Coltrane's musings on Africa are what I use to test out the bass of any loud speakers system and many fail to handle it. Trane stepped into the zone after these sessions. I think he loved Africa.
  • Abbey Lincoln - Afro-Blue
    Afro Blue was the centerpiece of Abbey is Blue, one of my favourite jazz albums. It's a stunning debut with a band plainly excited about her vocal stylings. She messes with the beat in this upbeat and jaunty song, playfully evoke a blue sentiment. I especially love her voicing of that lyric: "shades of delight, afro blue".

    Abbey is Blue


    Listen for the next week: Abbey Lincoln - Abbey is Blue

    I'll also point to her version of Africa sung almost a lifetime later. Again, the lyrics she supplies and the way she voices the words is incendiary. Abbey is back after last year's open-heart surgery and continues to do her thing. Thank goodness, I want to vibe with her some more.
  • Dianne Reeves - Afro Blue
    The head diva in charge gets down with Mongo Santamaria. Afro-Cuban and afro-blue stylings ensue. It's no wonder she was the first vocalist Blue Note enlisted.
  • Lizz Wright - Afro Blue
    She is a little too respectful of Abbey Lincoln in her take on the song. I think she could have made it her own in the way Dianne Reeves did. A missed opportunity perhaps, but it shows her impeccable taste and talent.
  • Horace Parlan - Congalegre
    Soul jazz aficionados loved this take on Ray Barretto's composition. The album appropriately enough is called Heading South
  • The Meters - Africa
    The funk trail starts from New Orleans. "Oh, take me back to the motherland".
  • Angelique Kidjo - Afrika
    A litle afro-pop from the Black Ivory Soul album. This was an international affair.
  • Toto - Africa
    Although overplayed in every eighties radio station, this is simply infectious pop music. A close reading of the lyrics reveal that they are pablum and a matter of cultural projection. Still everybody projects onto the Africa. As you know
    "the wild dogs cry out in the night as they grow restless,
    longing for some solitary company...
    I bless the rains down in Africa"
    Indeed.
  • Fela Kuti and Roy Ayers - Africa, Center of the world
    A great meeting of minds on Fela's turf, what's not to like? Afrobeat meets the vibes in the unhurried, discursive funk song and we hear music of many colours.
  • Dennis Brown - Africa (We Want To Go)
    The voice of reggae in his prime yearned for the motherland
  • Freddie McGregor - Africa Here I Come
    The best use of the full up riddim
  • Morgan Heritage - Africa, Here We Come
    "Protect Us Jah."
  • Reflection Eternal - Africa Dream
    Talib Kweli and Hi Tek expound from without on something deep inside of them
  • Youssou N'Dour - Africa, Dream Again
    After a few decades of stagnation, perhaps the continent can dream again. Certainly the young population hopes their dreams won't be deferred. This is taken from Youssou' Nothing's In Vain album. It is also the most syrupy pap he's ever recorded. I don't like his forays into commercial music and, especially when he starts singing in English, it is best left unheard. The étoile de Dakar and star of mbalax should come to the scene on his own terms.
  • Toumani Diabate's Symmetric Orchestra - Africa Challenge
    From the Boulevard de L'Independence album we have virtuosity from Diabaté' and his collaborators. Virtuosity, what more can I say
  • The African Brothers – Self Reliance
    Come up with your own strategies.
  • D'Angelo - Africa
    I'll end with a little voodoo. There is a certain naivete and hopefulness in this lullaby. The percussion of children's wind up toys is inspired. The vocal arrangement is lovely. It's about a renewal.

The Low End Theory of Networks

Ethan Zuckerman has been pondering generativity and aggregation, prompted by Jonathan Zittrain's paper, The Generative Internet and its implications. Many of these themes have been stewing in my head for quite some time so I thought I'd finally join in the conversation with some of my armchair punditry. As seems to be my custom, a one paragraph comment somehow turned into this note. Sadly I don't quite have a toli code to contribute to the fun, and I've already narrated a couple of gospels recently. Thus I'll switch tack and change the frame. This time I give you a theory: the Low End Theory.

Control versus Participation in Networks


It's interesting that the lawyers, from Lawrence Lessig on, are weighing in on these network things and it's about time... Generativity huh? Zittrain argues a legal case built on abundant economic evidence (and one hopes the linguists would also weigh in). It's a nice restatement of the End-to-End principle in terms palatable to lobbyists. And the argument is much like Lawrence Solum and Minn Chung's paper The Layers Principle: Internet Architecture and the Law from a few years ago.

Reed, Saltzer and Clark described the End-to-End principle quite simply in terms of systems design. The heart of the matter is this oft-overlooked sentence
Functions placed at low levels of a system may be redundant or of little value when compared with the cost of providing them at that low level.
They knew when they were writing that this notion had wider applicability than the telecommunication networks that were their initial focus hence they labeled their work "end-to-end arguments in system design". The costs that are borne by the "system" are a generativity tax if we use Zittrain's terminology.

In economic terms, if you read the system as a market, restating this principle turns it into a matter of preserving options value. Black and Scholes have a lot to say on this front.

I see this same notion everywhere in the software engineering that I practice. The most successful system in distributed computing has been the web which, by design (pdf) and to a fault, falls back on minimalist protocols and data formats to handle coordination costs and the human factor.

But there are also tensions at work in the design of any system, and hidden assumptions or vested interests at work.

There will always be a difference between the value of a system to its users and its value to its operators and this is perfectly expressed in networks. At issue in this discussion is who gets to see their utility maximized. As Martin Geddes puts it
If there’s one lesson of the Stupid Network, it’s that there’s a massive increase in consumer surplus. The value to users diverges from that to owners. You can’t measure user value by looking at industry revenue.
A priori you have no idea what options are possible at the edge of your market. This means that the design of the core of your system is a political decision. Like an options trader you are gambling on outcomes in the marketplace and attempting to manage risk. Your design decision is anything but neutral despite what the so-called "network neutrality" proponents say (even if I do agree with their endpoint market outcome).

We know that price discrimination is an optimal pricing strategy from many standpoints and, in market utility terms, it makes sense to optimize system design to enable some modicum of price discrimination. The evidence throughout history, however, is that participants in a market hate price discrimination and favour uniform or predictable pricing. For example, flat rate pricing made the fortunes of AOL, and block pricing is remaking the cell-phone industry. By analogy, Paris Metro pricing is not widespread in transportation systems and on the internet because of these explicit user preferences.

Part of the challenges the US airline companies currently face is that we aren't sympathetic to them. One major reason for our disdain is the pricing games that are played with plane tickets. We value fairness even though we are creatures of a rough jungle and there's likely an anthropological basis for our sense of indignation at price discrimination. Perhaps our past ancestors were optimistic planners by nature. However the presence of price discrimination in a market, coupled with flexibility of pricing, and the liquidity of relative transparency allows for the existence of middlemen and the possibility of arbitrage and disintermediation. On the whole, these are good market outcomes but, like many "options", they can't be characterized up front.

Where there are networks, we will find power laws that apply. Similarly where there are markets, we will have sharp elbows and monopolistic temptations as we scramble for the loot. There are echoes of F. Scott-Fitzgerald's notion that "the rich are very different from you and me". These factors are found in every part of the technology industry and, when combined, they play out in the Great Game of consolidation and lobbying. The big network operators will happily oblige in their strategies since lots of advantages accrue to the early movers and great powers, and they can leverage consumer inertia. In the internet we have many intermediaries at the network level; firewalls, middleboxes and the domain name system are potential, and actual, Great Powers (see the Verisign Tax ® we all pay and the "offers you can't refuse" that content delivery networks like Akamai make).

Moving up a level, intermediaries are acknowledged up front in the web architecture as design constraints. I have cast the web's embrace of visibility to intermediaries as Caesar's Tax Collector Principle and I think it is fitting, taxes are good, on the whole, and especially estate taxes - they keep the trains running and the streets clean at least in my neck of the woods.

The Rumsfeld Taxonomy of Networks


If we take Donald Rumsfeld's taxonomy of knowledge as the starting point for our analysis of networks, we find the following.

Unknown Unknowns


Legislators and vested interests tend to worry about "unknown unknowns" and, like Rumsfeld, will focus on threat models and such. This is a matter of governance and regulation; among the core competencies of most governments are the management of information and regulation. Excessive focus on these leads almost inevitably to data mining, intimidation, the co-option of a complaisant although ostensibly independent press, spying by the NSA , movie-plot security and the like, your basic Global Wars on Everyone.

Unknown Knowns


The "unknown knowns" are our unconscious biases that frame of the discussion of networks. The metaphors that different sides use are instructive and perhaps even my casting the conversation in terms of "sides" betrays my viewing this arena as a game of sorts (hopefully not Mortal Kombat or something). Others may view the networks scene as a Clash of Civilizations which would lead to apocalyptic wars and the End of History if one follows Manifest Destiny.

Known Knowns


The "known knowns" in networks have been visibly demonstrated in the economic verve and activity that is taking place on the internet. Even if the four horsemen of the internet ™ were oversold, we can still point to the ongoing transformation wrought by the Four Horsemen of the Web. As an engineer, I tend to think in terms of protocol, hence my nomination of The HUHXtable Quartet (HTTP, URI, HTML, XML) towards that designation. Your mileage may vary and various prognosticators seem to be weighing in with speculations about the identity of these horsemen. With corporations being legal humans, they have assembled an intriguing cast of characters to liven up the debate.

These same historical forces were at work in the history of communication and transportation networks (pdf) and, although we celebrate the Wright Brothers and Henry Ford, who is really celebrating Samuel Homfray, Richard Trevithick, and the various others who played a role in the history of railroads or even, more recently, the extraordinary innovation brought about by the lowly shipping container?

Known Unknowns


The sweet spots in our analysis are the "known unknowns". These are the things that make venture capitalists salivate, and monopolists turn to paranoia and worse. It's that seductive notion of the startup in the garage that can change the world, of the eBay or Craigslist economy, of the manufactured serendipity and furious and creative energy that has been on display in the past decade or so on the web. This is where that Long Tail notion comes into play, to shamelessly mine another meme. There is the sense that all you need is an idea, and good connections. The fully leveraged network can be a great leveler and promoter of the innovative forces in a system.

Sidenote: This bit about manufacturing serendipity on the road to riches meshes well with the American Dream ™ and it is worth commenting on a little. Paul Graham, in his hermetically-sealed world, apparently believes that a start-up culture is a particularism of the United States (or condensation as he puts it). What a peculiar notion. While he's sleeping soundly at night, after a lullaby of unshakeable Manifest Destiny, I'm sure that some Teutonic engineering will suddenly emerge (and he misreads the German economy so completely that he's a front runner for the huhudious awards 2006), or would it be an easterly wind that blows in from Korea or thereabouts that will give him fits early in the morning. I would have thought that the lesson was that the unknowns by definition are unknowable and, if you go ahead, following the Rumsfeld example, and discount even the knowns, you end up traveling in a lightly-armored Humvee on the road from Baghdad airport with a convoy of outsourced mercenaries. Good luck on that front.

The Low End Theory of Networks


But back to my topic... I'll quote Martin Geddes again since he is, as ever, eminently quotable
the end-to-end principle is really an appeal to preserve option value in a world of rapid technology change and innovation. By resisting this force, you’re either betting you can suppress rival distribution channels for competing innovation, or you can yourself be a lead innovator.
Thus Zittrain's pitch about generativity versus responsibility boils down to a tension between architectures of control and architectures of participation (using a much broader sense of participation than the current buzzword).

Stated another way, and since I traffic in coinages, indulge me if you will with Koranteng's first postulate of networks:
The End-to-End Principle in networks is another incarnation of the Low End Theory.
Recall if you will the core tenets of the Low End Theory which follows the Rule of Four as any good code should. Such is the mantra that schoolgirls the world over are reciting as they study Technology Adoption and System Design 101, and it is worth dwelling on:
  • Ruthlessly leverage disruptions in the system
  • Lower coordination costs through layer stripping
  • Favour participation over control
  • Temper the human factor to encourage adoption
As should be clear, each tenet of the Low End Theory encourages externalities to accrue in the system in support of preserving options value. Combined, they harness the collective energies of participants and harness innovation. We see these building blocks at work in hardware, in distributed computing and in the various Great Games that are taking place in the technology world. In this respect, I've suggested previously that REST, the web style, was the Low End Theory of Distributed Computing and have also written about The Low End Theory in Hardware. I don't see any reason why networks shouldn't be able to join in the fun, hence my current synthesis.

I like that Ethan is shrewdly focusing on the question of aggregation - that is also a restatement of the examples of eBay and Amazon. A good marketplace will surely allow for middlemen and aggregators, that's the bit about favouring participation. Aggregation however is only one of the styles that are likely to prevail in the market. Astute participants can focus on different areas and make hay.

As an example, it pays to identify the disruptions that underlie the evolution of the system, if you can hitch a ride at the right point, you can build mansions in Redmond. As to the second plank of our game theory, layer stripping restates the end-to-end notion of overlay systems, intelligence at the ends, and the daily reality of leaky abstractions. Similarly the human factor is a double-edged sword. On the one hand, there is the incoherence of the Tower of Babel which is the bit about coordination costs. On the other hand there are network effects to be gained in communication and group forming that argue for emphasizing community features in the system. From hunter-gatherers on, anything that enabled collaboration has given selective advantages in our evolutionary systems. We want to encourage the sharing of knowledge and information but encounter considerable costs in doing so. The ongoing dilemma we face is about how to build systems recognize the people along with the processes.

Operational efficiency is something that companies like Wal-Mart and Dell are good at, and operational efficiency at the margins is all the rage in the staid banking sector. As Willie Sutton quipped about robbing banks, it's "Cause that’s where the money is". Thus there are other ways to prevail in this marketplace. Rather than optimizing your processes around innovation you can optimize around operations, billing, search, storage, creating markets, or lubricating whatever friction there is in the system. To take an obvious example, the economics of peering is an interesting problem to tackle. Briefly stated it's Animal Farm all over again: some peers are more equal than others. Or call it real estate: location, location, location.

Similarly we are only beginning to realize the social implications of mobility in networks, of intermittent connectivity, of periodic synchronization and of the fluidity of our communal relations. Mobility is thus another of the major disruptions at work in the network marketplace and one that many users have voted on with cold cash all over the world. I'll note anecdotally that many colleagues of mine who were working on desktop collaboration software just years ago are now firmly ensconced at Nokia.

Where there is the realm of the social, there is the realm of conversation and its corollary, the market. To raise the tenor of this conversation, I'll repeat the insight of those 20th century philosophers, the Pet Shop Boys, and their master treatise:
There's lots of opportunities

You've got the brawn
I've got the brains
Let's make lot of money
Thus there is room in the network game for the innovation of Juniper and Skype and all the companies weighing in on the disruption of the internet protocols, and the operational effectiveness of say equipment manufacturers like Nokia and Samsung, and the more astute network operators. Everyone has their own exemplars on this last front: phone, cable, cell, fiber, copper, fixed wireless, wi-fi, ethernet... The TCP/IP suite that is the core of the internet has succeeded and scaled because the abstractions used embraced transparency and existing systems. The incredible ascendancy of ethernet over three decades (and of late wi-fi) is a testament to the value of simplicity and uniformity in network system design, and the concomitant scale and leverage that the low end mass market provides. Like the personal computer, these technologies are canonical disruptions and those who embrace their Fung Wah Bus aesthetic are inexorably moving up-market.

Some have suggested that good starting points for determining strategy are tomes like The Gorilla Game or The Innovator's Dilemma, I believe the jury is still out and the MBA types are best positioned to expound on their merit. I would point to Jim Gray's Distributed Computing Economics as my favourite starting point in determining to the best strategy. In any case, the game is on. In the interim, we are simply picking and choosing which of the hard problems we want to address. Still game theory remains theory; in real life games we have that nagging human factor.

Engineers are currently hobbled in our advocacy of the internet because we don't have good instruments for determining metrics for things like resilience and adaptability that could inform the decisions of policy makers, lawyers, economists, and those who really matter: Mr. and Mrs. Big Money. Politicians ever
