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...

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,...

In 2012, in the midst of a recession, a labour law reform in Portugal allowed firms to reduce the overtime premium paid to their workers by 50% or more. Until then, overtime premiums were set by law at a relatively high level and could not be cut unilaterally. We analyse matched...

In 2012, a new law allowed firms in Portugal to reduce the overtime premium paid by half. Until then, as in other countries, premiums were subject to a minimum level. We analyse matched panel data, including worker-level (base and overtime) hours and pay, to study the effects of the resulting...

Personnel economics tends be based on single-firm case studies. Here we examine the personnel practices of nearly 5,000 firms, over a period of 20 years, using detailed matched employer-employee panel data from Portugal. In the spirit of Baker et al. (1994a,b), we consider different dimensions...
