Concentración empresarial y cambio estructural: alimentos, bebidas y tabaco en México

Abstract

This article analyzes how major corporations in the food, beverage and tobacco industries in Mexico have grown, as well as potential implications for the structure and eficiency of this sector. Building a labor productivity indicator for 12 branches and 38 classes of activities for the 1994-2008 time period, and applying these to the series obtained from shift-share decomposition analysis, revealed growing structural heterogeneity along with increasing eficiency for a limited number of activities. Similarly, the results indicate that the impact of workers changing sectors on the evolution of productivity varies as a function of the business strategies adopted, but was negative on the whole for the period, evidence of a regressive structural change in the sector.
