The math of small contributions

This idea has been around for some time. I first read about it in, "small pieces loosely joined", by Dave Weinberger (one of the authors of the cluetrain). Anyway, Micheal Schrage has a good post, "Round-off Error? Hardly!" MIT Technology Review that applies the math. to the idea.

Mr. Schrage, "A brief disquisition as to why--when it comes to innovation--superficial economic analysis is worse than no analysis at all.

Let's start with the math: treating .1 percent of people as a "rounding error" may make economic sense if they don't do anything of substance or significance. But if they actually create and add value to your network and/or your business, you might be wiser to treat that magnificent tenth of a percent as an "outlier" to be nurtured rather than a statistical aberration to be ignored.

Indeed, as Mr. Harford well knows, 10 percent of a thousand is larger than 90 percent of a hundred. If we have--and we do!--Net enterprises with tens of millions of users, then that measly-looking .1 percent can be misleadingly robust. One-tenth of a percent of a million is a thousand, and, of course, .1 percent of 10 million = 10,000. That's quite a workforce. But why grant Tim his self-serving assumptions? I cheerfully argue that as a "culture of contribution" and creative volunteerism facilitates a vibrant innovation marketplace, that tenth of a percent might really be closer to seven-tenths of a percent or even 1 percent. Again, it's not the volume of contributors that matters; it's the value of their contributions. Isn't that what economics is supposed to be about? Hence my dismay with and dismissal of our Undercover Economist's "analysis."

The simple truth is that we can look at any industry--automobiles, semiconductors, telecoms--and find only a tiny fraction of "entrepreneurs" who are making real contributions. Now, I'm not for a moment suggesting that folks who volunteer their videos on Youtube or comments on Amazon or story preferences on Digg are entrepreneurs in the Schumpertarian or Hayekian sense. The (obvious) profit motive is absent. However, the community/audience/marketplace clearly sees some value in these contributions--as do the undeniably entrepreneurial hosts. The spirit--and seduction--of "increasing returns" suggests that literally tens of thousands of people will be making value-added contributions to these arenas and that, yes, noncontributing consumers will also extract some value from them. In other words, Harford's "rounding error" assertion is a bit like saying, "You know those tiny little things that huge trees have called seeds? Well, they're so small and lightweight, they don't really matter. I mean, they're not even one-tenth of one percent the size or weight of the tree...." Just as bad botanical understanding can wipe out forests and biodiversity, poor economic analysis can wipe out value and its creation. The truth is that we're just beginning to grasp the underlying behavioral economics of "open source" and "cooperative" innovation economies. Dismissing what we don't understand as "round-off error" makes poor punditry and worse economics.
