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...

We present evidence about the role of rent sharing in fostering the interdependence of labour markets around the world. Our results draw on a firm-level panel of more than 2,000 multinationals and more than 5,000 of their affiliates, covering 47 home and host countries. We find considerable...

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 provide new evidence about earnings and labour market volatility in Britain over the period 1992-2008, and for women as well as men. (Most research about volatility refers to earnings volatility for US men.) We show that earnings volatility declined slightly for both men and women over the...
