The year 2011 marked 75 years since the publication of The General Theory of Employment, Interest and Money. It was published on 4 February 1936 in the middle of an economic depression, a time in which politicians were groping in the dark with little help from the field of economics. People were queuing to buy the book as soon as it was released, and expectations were high. There are many similarities between then and now, including unemployment, low growth and mounting public debt. Unfortunately, nobody is talking about a new ‘General Theory’ being on the way, which gives us all the more reason to re-read and reconsider Keynes’s seminal book. At the brink of the 21st century, a number of academic economists were asked which economist they considered to have had the greatest impact on the 20th century. Most named Keynes, many referring directly to The General Theory; but this vote was about influence in the past. One hardly sees references to Keynes in macroeconomic textbooks any more – perhaps a passing remark related to the case of rigid wages in the labour market (which only demonstrates that the author has not read The General Theory). Given the number of similarities between the economic crisis of the 1930s and the present one, we considered this an obvious time to gather Keynes scholars from around the world to discuss and exchange views on the ‘relevance and perspectives’ of The General Theory for this century.
