This paper draws on employer-employee and longitudinal plant data from Mexico to investigate the impact of exports on wage premia, defined as wages above what workers would receive elsewhere in the labor market. We decompose plant-level average wages into a component reflecting skill composition and a component reflecting wage premia. Using the late-1994 peso devaluation interacted with initial export propensity as a source of exogenous changes in exports, we find that exports have a significant positive effect on wage premia, and that the effect on wage premia accounts for essentially all of the medium-term effect of exporting on plant-average wages.

We construct a novel data set matching occupational data from separate establishments to the establishments' corporate parents, in order to study labor market links across establishments within diverse firms. We find substantial wage components common to all establishments within firms, even after netting out industry and occupation effects. However, employment changes are localized to establishments. The data suggest that internal labor markets of multiestablishment firms are linked throughout their entire organizations, but that establishment-level demand shocks do not permeate the firm.
