The Dynamics of Agriculture Supply: A Reconsideration


  • Zvi Eckstein


This paper presents a dynamic rational expectations equilibrium model for a given crop. The dynamic supply equation is derived from the farmer optimization problem; and the equilibrium movements of commodity price, production, and land allocations are solved analytically. It is shown that the observed dynamics of agriculture supply, which are usually explained and measured with the Nerlovian supply response model, can be explained and measured at least as well by the rational expectations equilibrium model. However, interpretation of the results is different, and the paper defines explicitly the dynamic supply elasticities and presents an econometric method for consistent estimators for the parameters.
