Stephen J. DeCanio

Professor of Economics, Emeritus

University of California, Santa Barbara

My current research deals with the impact of Artificial Intelligence on human society, the economy, and culture.

In the recent past I have examined the consequences of computational limits for economics and social theory more generally in Limits of Economic and Social Knowledge (Palgrave Macmillan, 2013).  Over the course of my career I have worked in the fields of global environmental protection, the theory of the firm, and economic history.  I have written about both the contributions and misuse of economics in debates over long-run policy problems such as climate change and stratospheric ozone layer protection. My book, Economic Models of Climate Change: A Critique (Palgrave Macmillan, 2003) discusses  the problems with conventional general equilibrium models when applied to climate policy.

From 1986 to 1987 I was Senior Staff Economist at the President’s Council of Economic Advisers. I have been a member of the United Nations Environment Programme’s Economic Options Panel, which reviewed the economic aspects of the Montreal Protocol on Substances that Deplete the Ozone Layer, and I served as Co-Chair of the Montreal Protocol’s Agricultural Economics Task Force of the Technical and Economics Assessment Panel. I participated in the Intergovernmental Panel on Climate Change that shared the 2007 Nobel Peace Prize, and was a recipient of the Leontief Prize for Advancing the Frontiers of Economic Thought in 2007. In 1996 I was honored with a Stratospheric Ozone Protection Award, and in 2007 a “Best of the Best” Stratospheric Ozone Protection Award from the U.S. Environmental Protection Agency. I served as Director of the UCSB Washington Program from 2004 to 2009.
