Equilibrium quantity and timing of exports of Mexican vegetables

In order to evaluate possibilities for further expansion a linear programming production model for specific regions in Mexico was constructed and tested. Various equilibrium situations were analyzed to appraise possible future trends. Special features of the model were the inclusion of risk, demand functions for all crops, and allowances for both competitive and monopolistic supply structures. It was concluded that rising wage rates and tighter supply controls would halt Mexico"s expansion of export winter vegetables.
