In a thought-provoking presentation during the IMF Fiscal Affairs Department’s (FAD) 50th Anniversary Conference on December 5, 2014, Professor Ravi Kanbur of Cornell University analyzed the intellectual origins and roots of FAD. In his view, these roots derive not from the influence of Keynes, one of the founding fathers of the IMF, who was more concerned with issues of monetary policy and balance of payments stabilization than with fiscal policy. A much stronger influence on FAD’s development was one of Keynes’ illustrious colleagues at Cambridge University, Arthur Pigou. Professor Kanbur’s main thesis [Presentation_Available here (.ppt)], however, was that FAD, while responsible for many important applications of fiscal policy, had taken little advantage of important recent work on political economy analysis, and the application of behavioral economics to fiscal issues. These developments derive from the work of notable economists such as Knut Wicksell and 2002 Nobel Prize winner Daniel Kahneman. Another strong influence has been the work on public choice theory and the economics of state bureaucracy, a line running from Pareto, through the great Italian school of public finance to the work of scholars such as Buchanan, Tullock and Peacock.
