Soberanía Alimentaria de granos básicos en México: un enfoque de cointegración de Johansen a partir del TLCAN

This document presents a graphical and econometric analysis of food sovereignty of basic grains (rice, beans, corn and wheat), measured through their imports, for the case of Mexico since the establishment of NAFTA. The graphical analysis described the behavior of the harvested area, the production, the import, as well as the supply of each crop. Regarding the econometric analysis, a Johansen cointegration approach was used, with which the income and price elasticities of the demand for basic grain imports were gotten. It was concluded that food sovereignty deteriorated in the period 1994-2016; each year Mexico depended more on imports to satisfy domestic demand of basic grains, increasing this demand with raises in economic activity and the real exchange rate.
