Stephen J. DeCanio is Professor of Economics, Emeritus, at the University of California, Santa Barbara. Much of Professor DeCanio's research has dealt with global environmental protection. He has written about both the contributions and misuse of Economics to debate long-run policy problems such as climate change and stratospheric ozone layer protection. Professor DeCanio has written extensively on corporate organization and behavior as it pertains to the adoption of energy-efficient technologies. His book, "Economic Models of Climate Change: A Critique" (Palgrave Macmillan, 2003), discusses some of the problems with conventional general equilibrium models when applied to climate policy. His most recent research focuses on the consequences of the computational limits for social theory more generally. His latest book, "Limits of Economic and Social Knowledge" (Palgrave Macmillan, 2013), offers an extended treatment of the implications of these limits.
