MARTINEZ-DAMIAN, M. Ángel  y  HERNANDEZ-ORTIZ, J.. Basic grains imports and domestic price in México: an inverse-demand system approach. agric. soc. desarro [online]. 2012, vol.9, n.4, pp.401-410. ISSN 1870-5472.

In this article, the reducing effect of imports on prices of five basic products is estimated: rice (Oryza sativa), bean (Phaseolus vulgaris), maize (Zea mays), sorghum (Sorghum spp.), and wheat (Triticum aestivum). After applying an inverse-demand system, the results show that this effect is lower than one, in proportional terms, and therefore a policy of price regulations based on imports turns out to be costly in expenditure.
