We estimate the impact of union density on wages using Portuguese matched employer-employee-contract data, extending Gelbach's (2016) omitted variable bias decomposition procedure to obtain the contribution of worker, firm, and job-title heterogeneity to the union wage premium. The principal...

This paper provides the first definitive estimates of union density in Portugal, 2010-2012, using a unique dataset. The determinants of union density at firm level are first modeled. Next, we draw upon a very recent study of the union wage premium to provide summary estimates of the union wage...

This paper provides estimates of the union wage gap in Portugal, a nation until recently lacking independent data on union density at firm level. Having estimated nonlinear and linear estimates of the effect of union density on the wage gap, the next stage of the analysis seeks to account for...

Using matched employer-employee-contract data for Portugal - a country with near-universal union coverage - we find evidence of a sizable effect of union affiliation on wages. Gelbach's (2016) decomposition procedure is next deployed to ascertain the contributions of worker, firm, match, and...

At first blush, most advances in labour demand were achieved by the late 1980s. Since then progress might appear to have stalled. We argue to the contrary that significant progress has been made in understanding labour market frictions and imperfections, and in modelling search behaviour and...
