摘要：The United States embarked on a policy assuming excess demands for commodities are elastic. Some analysts question the success of that policy and argue that excess demands for farm commodities are inelastic. The controversy is deepened because the two traditional techniques for determining excess demand elasticities yield opposing estimates. We use an alternative technique based on observed variation in commodity prices, production, and use. The point estimates show excess demands for wheat, coarse grains, soybeans, rice, and cotton are elastic. However, a one-sided bootstrap test cannot reject the null hypothesis that the excess demands for wheat, coarse grains, and soybeans are inelastic.
