The Farm War of the early 1980s was rooted in the political economy of agriculture, but it was a crisis for the international trading system. The war was evident in disruptions on the farm and in world markets, in conflicts among major governments, and in disagreements in international organizations. Wolfe shows how and why battles over agricultural protectionism were largely resolved through the Uruguay Round of GATT negotiations, demonstrating that the global economy is not self-regulating: it needs institutions if it is to be stable.
