Thirty years ago, when John Kenneth Galbraith published The New Industrial State, he was sure he knew where the modern economy was going and was contemptuous of economists who clung to their old ideas about the primacy of markets. Clearly giant corporations, driven by the imperatives of technology, were replacing the chaos of the market with bureaucratic order. The age of business heroes was over: "With the rise of the modern corporation, the emergence of the organization required by modern technology and planning and the divorce of the owner of capital from control of the enterprise, the entrepreneur no longer exists as an individual person in the mature industrial enterprise." The economy of the future would be run by faceless organization men, whose ability to manipulate pliable consumers would eliminate the traditional uncertainties associated with market competition. In effect, capitalism was evolving spontaneously into socialism without the justice.
Instead, of course, only the paranoid survived, or something like that. And yet Galbraith's mistake--believing that one can discern the shape of tomorrow's economy by extrapolating from today's iconic corporations--is one that each generation seems to repeat. Yesterday every industry was going to look like automobiles, and every company like General Motors; today every industry is going to look like software, and every company like Microsoft.
Like Galbraith, the prophets of what is variously called the "business revolution," the Knowledge Economy, the Network Economy, and the "new economy" (not to be confused with the New Economy I wrote about last month) are likely to be disappointed. Even though information technology may well be the main driving force behind future economic growth, it's very unlikely that the information-technology industry is ever going to be more than a fairly small share of the economy. In its day electricity changed everything, too, but there was never a time when most people worked for electric utilities or even for employers who looked anything like electric utilities. Still, even if every industry isn't about to look like software, it is worth asking what is special about those industries that do.
It's important to get past the obvious, but mainly irrelevant, surfaces of things. Of course information technology is nifty; but the latest technology always seems nifty (At the 1876 Philadelphia Centennial Exposition, triumphant banners proclaimed "All By Steam!"). The real question is whether there really are, as Wired's Executive Editor Kevin Kelly put it in the title of a widely read recent article, "New Rules for the New Economy."
Kelly manages to come up with no less than 12 such rules, ranging from the more or less incomprehensible ("Embrace dumb power") to the basically silly ("Follow the free"), all wrapped in trendy rhetoric about living "on the edge of chaos" and all that. But most of his rules amount to variations on two themes: In the Network Economy supply curves slope down instead of up, and demand curves slope up instead of down. At least, that's what I think he's saying. To the extent that he is, he is actually on to something--though not something new.
True, traditional economic theory--the stuff that occupies the first 10 or so chapters of most introductory textbooks--does assume "diminishing returns" in both production and consumption. That is, the more units of something the economy is already producing, the harder it is to produce one unit more; the more units of something people are already consuming, the less they are willing to pay to consume one unit more. That is why the conventional supply curve, which shows how much will be produced at any given price, slopes up; and the demand curve, which shows how much people will buy at any given price, slopes down.
B ut even Alfred Marshall--the Victorian economist who invented supply and demand as we know it--was well aware that while diminishing returns are a good assumption for agriculture (The more wheat you try to grow, the worse the land on which the marginal bushel is grown), elsewhere in the economy it is quite possible to have increasing returns, in which the more you produce, the easier it gets. Way back in 1890 he explained that concentrations of industry (yes, they existed before Silicon Valley--his prime example was the Sheffield cutlery district) can create a virtuous circle in which the availability of skilled labor, the presence of specialized suppliers, and the diffusion of knowledge. Increasing returns to consumption are probably less common, but can result among other things from "network externalities"--a bit of useful jargon for what happens when the usefulness of a product depends on how many other people possess something similar. A telephone is a toy when only a few people have one; it is a necessity when everyone has one.
The old-fashioned examples are deliberate: Increasing returns have been around for a long time. And while economists may historically have downplayed their importance, those days are long past. In fact, by now, increasing returns are rather old hat. Everybody knows that sufficiently strong increasing returns can cause discontinuous change, with markets exploding when they reach a "critical mass," that small events can have big effects when a market is near a "tipping point," that economic choices (like VHS vs. Betamax, or Silicon Valley vs. Route 128) can be subject to "lock-in" by past accidents, and so on. Everybody also knows that while it is easy to tell good stories along these lines, it's a lot harder when you get down to real cases: It's amazingly hard to identify a critical mass or a tipping point for an actual industry, even after the fact.
S o what's new about Kelly's New Rules? Well, for one thing, they may be new to him. Cybercritic Paulina Borsook has pointed out to me that technology enthusiasts like Kelly are prone to "Luke Skywalker fantasies," imagining themselves heroic rebels against the empire of orthodoxy. (The quintessential example of the Luke Skywalker Syndrome is the story of Brian Arthur, as described in my column last week.) They are so sure that boring conventional thinkers could not have anticipated their radical ideas that it would never occur to them to check.
Or maybe what's new about the rules is the claim that now, for the first time, they apply to a large part of the economy. However, technology boosters, who won't stop thinking about tomorrow, often forget to think about yesterday: It's not at all clear that increasing returns are any more important in software than they were in the early days of railroads, electricity, telephones, radio, even automobiles (What good is a car without gas stations? Why open a gas station if nobody has a car?). And it's very unlikely that in the future everything will look like software--indeed, it's much more likely that eventually the information sector itself will turn into a boring mature industry.
