Excess supply and price volatility in the Mexican potato market: a decision making framework.

摘要

The objective of this research was to use a spatial and inter-temporal equilibrium model to develop a plan to assist the Mexican potato production sector in moderating extreme swings in potato prices. Results indicate that excess supplies of potatoes in some months could be eliminated with a storage policy or if changes in irrigated potato production were implemented. The storage policy and changes in production practices would reduce price volatility and increase producer incomes; however, a storage policy cannot be recommended due to the large capital investment required for storage infrastructure development. Seasonal production planning would increase producer incomes by more than 1,500 million pesos and not require extensive capital investment
