RETES MANTILLA, Rogel Fernando; TORRES SANABRIA, Guillermo  e  GARRIDO ROLDAN, Samuel. An econometric model of demand of maize tortilla in Mexico, 1996-2008. Estud. soc [online]. 2014, vol.22, n.43, pp.37-59. ISSN 0188-4557.

The maize tortilla is a fundamental food in the diet of the Mexicans. Nevertheless, its demand diminished 36.7% from 1996 to 2008. The objective of this study was to identify and to measure through strata the main economic factors that affected the demand of maize tortilla in Mexico. For it, three uniecuacionales models of the behavior of their demand were estimated using data of ENIGH and Banxico. The results indicate an inelastic answer of the consumers to the changes in the price of the tortilla, expenditure and related goods; reason why the tortilla behaves like a normal inferior good for the strata before referred. Also, the bean, the pork, the beef, the sauce (chili, tomato and onion) and the cheese work like tortilla's complement, and the bread, rise and potato works like their substitutes.

Palavras-chave : basic food; inferior good; substitute goods; expenditure; price.
