In principle, firms in developing countries benefit from the fact that advanced technologies and products have already been developed in industrialized countries and can simply be adopted, a process often referred to as industrial upgrading. But for many firms this advantage remains elusive. What is getting in the way? This paper reviews recent firm-level empirical research on the determinants of upgrading in developing countries. The first part focuses on how to define and measure various dimensions of upgrading—learning, quality upgrading, technology adoption, and product innovation. The second part takes stock of recent evidence on the drivers of upgrading, classifying them as output-side drivers, input-side drivers, or drivers of know-how. I conclude with some thoughts about promising directions for research in the area. (JEL D21, D24, D83, F14, L26, O14, O31)

Comparing two sources of wage data in Mexico—firms' reports to the social security agency and individuals' responses to a household survey—we document extensive underreporting of wages by formal firms, with compliance better in larger firms. We also present evidence that the 1997 Mexican pension reform, which tied pension benefits more closely to reported wages for younger workers, led to a relative decline in underreporting for younger age groups. The results suggest that giving employees incentives and information to improve the accuracy of employer reports can be an effective way to improve payroll tax compliance.

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.
