We conduct a meta-analysis of more than 30 papers that study the causal relationship between exporting and firm productivity. Our results, robust to different specifications and to different weights for each observation, indicate that the impact of exporting upon productivity is higher 1) at...

Using matched employer-employee panel data, we estimate measures of pay dispersion per firm-year that take into account both rm and worker unobserved heterogeneity. Unlike research that controls only for differences in observables, we nd that within-firm pay inequality is significantly...

In the context of the debate on the labour-market consequences of globalisation, we examine worker mobility in order to identify the wage differences between foreign and domestic firms. Using matched employer-employee panel data for Portugal, we consider virtually all spells of interfirm...

How much do developing countries benefit from foreign investment? We contribute to this question by comparing the employment and wage practices of foreign and domestic firms in Brazil, using detailed matched firm-worker panel data. In order to control for unobserved worker differences, we...

Theory and evidence are ambiguous about the effect of within-firm wage inequality on firm performance. This paper tests empirically this relationship drawing on detailed Brazilian matched employer-employee panel data, considering alternative measures of inequality and performance and different...

Many biases plague the analysis of whether employers share rents with their employees, unlike what is predicted by the competitive labour market model. Using a Portuguese matched employer-employee panel, these biases are addressed here in three complementary ways: 1) Controlling directly for the...

We present evidence about the effects of dismissals-for-cause requirements, a specific component of employment protection legislation that has received little attention. We study a quasi-natural experiment generated by a law introduced in Portugal: out of the 12 paragraphs in the law that...

Do workers benefit from the education of their co-workers? This question is examined first by introducing a model of on-the-job schooling, which argues that educated workers may transfer part of their general skills to uneducated workers and that this spillover is affected by the degrees of...

Many biases plague the estimation of rent sharing in labour markets. Using a Portuguese matched employer-employee panel, these biases are addressed in this paper in three complementary ways: 1) Controlling directly for the fact that firms that share more rents will, ceteris paribus, have lower...
