The Turkish M.I.T. professor — who, right now, is about as hot as economists get — acquired his renown for serious advances in answering the single most important question in his profession, the same one that compelled Adam Smith to write “The Wealth of Nations”:
Why are some countries rich while others are poor?
Over the centuries, proposed answers have varied greatly. Smith declared that the difference between wealth and poverty resulted from the relative freedom of the markets; Thomas Malthus said poverty comes from overpopulation; and John Maynard Keynes claimed it was a byproduct of a lack of technocrats. (Of course, everyone knows that politicians love listening to wonky bureaucrats!) Jeffrey Sachs, one of the world’s most famous economists, asserts that poor soil, lack of navigable rivers and tropical diseases are, in part, to blame. Others point to culture, geography, climate, colonization and military might. The list goes on.
But through a series of legendary — and somewhat controversial — academic papers published over the past decade, Acemoglu has persuasively challenged many of the previous theories. (If poverty were primarily the result of geography, say, or an unfortunate history, how can we account for the successes of Botswana, Costa Rica or Thailand?)
Now, in their new book, “Why Nations Fail,” Acemoglu and his collaborator, James Robinson, argue that the wealth of a country is most closely correlated with the degree to which the average person shares in the overall growth of its economy. It’s an idea that was first raised by Smith but was then largely ignored for centuries as economics became focused on theoretical models of ideal economies rather than the not-at-all-ideal problems of real nations.
