This short paper examines the effect of exporting on within-plant wage distributions in employer-employee data on Mexican manufacturing plants. Using the late-1994 peso devaluation interacted with initial plant size as a source of exogenous variation in exporting and focusing on wages at the 10th, 25th, 50th, 75th and 90th percentiles within each plant, we document three patterns: (1) there is no evidence of an effect of exporting on wages at the 10th percentile; (2) the wage effects of exporting are larger at higher percentiles, up to the 75th; and (3) there is no evidence of an increase in dispersion within the top quartile.

This paper draws on employer-employee and longitudinal plant data from Mexico to investigate the impact of exports on wage premiums, 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 premiums. 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 premiums and that the effect on wage premiums accounts for essentially all of the medium-term effect of exporting on plant-average wages.
