Leo K. Simon was an adjunct professor in the Department of Agricultural and Resource Economics, University of California-Berkeley. He held a BA degree and a Concert Diploma of Music from the University of Melbourne, Australia. He obtained MS degrees in International Relations and in Economics from the London School of Economics, and a PhD in Economics from Princeton University. Simon’s research interests ranged from theoretical game theory to simulation modeling to applied political economy. His work in political economy applied a game-theoretic model of multiissue, multiplayer negotiations developed in collaboration with Gordon Rausser. With Rausser and others, he completed a study of water resource allocation across subbasins of the Adour Basin of Southern France. One application studied the current negotiations over the Water Transfer Agreement between IID and SDCWA in Southern California. Another compared the political economics of agri-environmental policy formation in Europe and the United States, and the role played by the WTO in these two regions.
