Mr. Gintis is schooled in contemporary neoclassical economics that trivializes and sometimes even denies the existence of Ricardian rent, and naturally has difficulty separating and identifying natural resource rents from other components of the economy. This is most disappointing, as substantial strides have been made in showing the amount and significance of rents since the advent of computer power and data can be tapped. Australian economist Terry Dwyer, himself Harvard educated, shows that just the ground rent from earthly locations is about a third of GDP. And Professor Gaffney's most recent article in the International Journal of Social Economics shows the numerous ways in which rent has been under-estimated. Professor Gintis gets a number of his facts wrong in this review: Henry George's Progress and Poverty was first published in 1879 and not 1987, and by 1906 had been translated into fourteen languages and sold more copies than any book published except the Bible. Contemporaries of the era were intellectual luminaries and statesmen, among them Bernard Shaw, Winston Churchill, Sun Yat Sen, Leo Tolstoi, and Alfred Russell Wallace. More recently, Illinois economics professor and later Paul Douglas was a strong supporter of these ideas, as was Albert Einstein. John Dewey wrote an introduction to one edition of Progress and Poverty, saying "It would require less than the fingers of the two hands to enumerate those who, from Plato down, rank with Henry George among the world's social philosophers. No man, no graduate of a higher institution, has a right to regard himself as an educated man in social thought unless he has some first-hand acquaintance with the theoretical contribution of this great American thinker." Later, at the depth of the depression, Dewey gave a radio broadcast in homage to George. More recently still some eight Nobel laureates in economics have endorsed taxing economic rents, and Columbia University Professor Bill Vickrey was on his way to a Georgist convention when he died.
Professor Gaffney's collected work spans seven decades, and he continues to be active -- his most recent book, After the Crash, is printed by Wiley Blackwell. As evidence mounts in recognition of the importance of economic rent in our contemporary economy, only those who wear blinders will continue to deny its significance. He continues to inspire many young scholars. It is fortunate that we have the benefit of Mason Gaffney's enormous corpus of articles, www.masongaffney.org, for it is now, as neoclassical economics is collapsing of its own contradictions, that the tradition of classical economics is being looked to once more. One could do far worse than to start by exploring the many Georgist websites that continue to explore and amplify this venerable tradition. Links can be found readily on Professor Gaffney's site.
