The analysis of the effects of firm-level international trade on wages has so far focused on the role of exports, which are also typically treated as a composite good. However, we show in this paper that firm-level imports can actually be a wage determinant as important as exports. Furthermore,...

This paper presents evidence that real wage cyclicality can be a particularly heterogeneous parameter, depending on different worker characteristics and also on the specific stage of the business cycle. Using matched employer-employee panel data for Portugal covering the period 1986-2004, real...

EPIS is an original and large private-sector program aimed at improving student achievement and eroding early school leaving at Portuguese state schools. The program first screens students to focus only on those more likely to perform poorly; and then conducts a number of small-group sessions...

Using matched employer-employee data, we analyse the impact of immigrants on natives' employment in Portugal. Using different model specifications, we show that the natives and immigrants are 'complements' at most occupation levels, in the sense that they are jointly hired and fired. Controlling...

We investigate the relationship between exporting, importing, and wage premia using a rich matched employer-employee data set. We improve on the previous literature (i) by using a new methodology to quantify the contribution of an extensive set of worker- and firm-level observable and...

We show why considering a number of education-dependent covariates in the wage equation decreases coefficient of education in the wage equation. We use a meta-analysis of results for Portugal to show, empirically, that this is the case. The coefficient decreases when we use covariates that can...

We address the impact of education upon wage inequality by drawing on evidence from fifteen European countries, during a period ranging between 1980 and 1995. We focus on within-educational-levels wage inequality by estimating quantile regressions of Mincer equations and analysing the...

We contribute to the literature on Foreign Direct Investment and labour markets by examining wage differentials between domestic and foreign firms, drawing on a large Portuguese matched employer-employee panel. Using OLS, the foreign-firm premium is large and significantly positive but falls...
