Peddling Prosperity
Peddling Prosperity: Economic Sense and Nonsense in an Age of Diminished Expectations is a book by Nobel laureate and New York Times columnist Paul Krugman, first published in 1994 by W. W. Norton & Company. Overview
Shortly after its publication, Newsweek called it "the best primer around on recent U.S. economic history." In the book Krugman covers the US productivity slowdown that has occurred since the 1970s, changes in the ideology among economists, and offers critiques of both conservative supply side economics and liberal support for government intervention in the form of "strategic policy". Krugman argues the rise of the supply-side economics is produced by the inability of opposing economists to convincingly explain certain economic phenomena, such as the US productivity slowdown. He criticizes  monetarism, rational expectations theory, and conservative economists' views on taxes and regulation. One of the major themes of the book is that the difference between real economic theory and "policy entrepreneurs", who peddle politically popular but academically wrong ideas, is as important as the polarization between the political left and right in America. Krugman describes these "policy entrepreneurs" as non-academics who promote particular intellectual positions and ideological policy prescriptions in areas where a problem is perceived to exist. The success of these so-called "policy entrepreneurs", according to Krugman's is at least partly due to the unwillingness and inability of competing economists to effectively communicate their opposing ideas in a rationally received manner; a shortcoming which Krugman's book is meant to address. A portion of the subtitle of the book refers to an earlier book by Krugman, Age of Diminished Expectations (1990). References
