PEREZ VERA, Flor del Carmen; MARTINEZ DAMIAN, Miguel Ángel; GARCIA MATA, Roberto  and  ESPINOSA TRUJILLO, Marco Antonio. Simultaneous effect between consumer prices of the main meats consumed in Mexico. Rev. Mex. Cienc. Agríc [online]. 2015, vol.6, n.2, pp.239-251. ISSN 2007-0934.

In the present investigation was proposed that the real consumer price of the main meats consumed in Mexico (beef, pork and chicken) are interwoven with the displacement demand factors such as the price of their respective substitutes and income; thus price was taken as the dependent variable in function of the quantity demanded, which allowed to estimate simultaneously the functional relationships of each of the meats, modeling joint endogeneity. According to this, the proposed model is estimated through least squares in three-stages for the period 1961-2010; the effects on the price in open economy were quantified by a sensitivity analysis for the period 1994-2010. The results indicated that there is a substitution effect between pork and beef, being the price of pork more sensitive to changes in the price of its substitute. Pork and chicken are substitutes for each other, being these goods cheaper compared to beef; with a greater effect on the price of chicken meat to changes in consumer prices of pork. No substitution between beef and chicken was found. The trade liberalization policy had a negative effect on the average level of consumer prices of pork and chicken, while for beef the same effect was positive.
