Abstract :
An agricultural market model which includes the effects of government support and stockpiling programs has been developed as a component of AGRIMOD, a dynamic simulation model of the U.S. food production system. The model is formulated as a nonlinear optimization problem with nonlinear constraints. The concept of a Support supply function is introduced to deal with discontinuities in the supply caused by government policies. Finally, a scaling method is developed to achieve rapid convergence.
