This paper focuses on U.S. agriculture response to policy reform. A growing body of empirical literature describes the potential aggregate gains for the U.S. markets if global agricultural tariffs and subsidies can be further reduced (USDA, 2001; World Bank, GEP 2002; Tokarick, 2003). These gains are based on an aggregation of expected responses at the micro-level, by firms and households, to changing market conditions. Some of them will be "gainers" whose current economic activities and assets will benefit from the new opportunities presented by policy reform. Some will be "losers" who are adversely affected by the reduction or loss of subsidies or import protection.
