A Decade of the New Growth Economics: A Comment on Sala-i-Martin, "I Just Ran Two Million Regressions"

Опубликовано на портале: 12-07-2007
Here we have Sala-i-Martin's attempt to write a compressed twelve-page Summa Theologica of the past decade's work in empirical studies of cross-country growth patterns. Whatever cross-country regression of rates of growth on political and economic variables any future researcher chooses to run, the chances are very good that it will be among the two million total (455,126 separate) regressions run by Sala-i-Martin.

My first thought was that Sala-i-Martin had constructed the economist's equivalent of Jorge Luis Borges's "Library of Babel"--the library that contains all possible books, but that its useless because nothing can be found. Yet that is not correct, for Xavier Sala-i-Martin has managed to provide us all with a rough synopsis of the results of all his regressions.

Let me focus on Xavier Sala-i-Martin (1997), and note that examining Hall and Jones (1996) leads basically to the same conclusions.
