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

This paper provides evidence about the effects of dismissals-for-cause requirements, aspecific component of employment protection legislation that has received little attentiondespite its potential relevance. We study a quasi-natural experiment generated by a lawintroduced in Portugal in 1989:...

In this paper we show that panel estimates of tenure specific sensitivity to the business cycle of wages is subject to serious pitfalls. Three canonical variates used in the literature – the minimum unemployment rate during a worker's time at the firm (min u), the unemployment rate at the...

Politicians can use the public sector to give jobs to cronies, at the expense of the efficiency of those organisations and general welfare. Motivated by a simple model of cronyism that predicts spikes in appointments to state-owned firms near elections, we regress 1980-2008 monthly hirings...

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...

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...

This paper analyses to what extent working conditions in foreign-owned firms differ from those in their domestic counterparts. It makes three main contributions. First, we replicate the consensus in the empirical literature by applying a standardised methodology to firm-level data for three...

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...

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...

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,...
