The Dismal Science at Age 230

"The dismal science?"  You won't be surprised to hear that that's about the last way I'd describe the art and discipline of economics, and a new book, Knowledge and the Wealth of Nations, reviewed by Paul Krugman in yesterday's Sunday Times Book Review sounds like a wonderfully exciting intellectual exploration of why I believe economics retains its ability to fascinate as it attempts to explain how people, ideas, and things interact to try to produce value.

 The author, David Warsh, a former economics correspondent at the Boston Globe, Forbes, and The Wall Street Journal, writes the online weekly, "Economic Principals."  The book tells the story of how academic understanding of increasing returns to scale, and indeed of growth itself, was revolutionized in the past few decades by introducing the concept of knowledge itself as a factor of production, at long last joining the classical triumvirate of land (a/k/a tangible resources), capital, and labor.

When a book gets advance praise like this, the reason I continue to adore economics should be clear:

“Romer’s understated but earth shattering work deserves our attention and a Nobel prize in economics.”
