Why have agricultural policies become more inward-looking as the world becomes increasingly interdependent economically? Disarray in World Food Markets addresses the nature and causes of this crisis in international trade policy. Its analysis of the effects of these food policies is complemented by a quantitative review of the long term trends in world food markets. The study also extensively examines the reasons why governments choose to implement distortionary policies. This ambitious book, based on a dynamic, multi-commodity model of world food markets, will be an important reference work for policy practitioners and all those with an interest in trade policy, particularly in countries active in the trade negotiations.
