This study examines the potential impact of works councils and unions on the deployment of fixed-term contracts and agency temps. We report inter al. that works councils are associated with a higher number of temporary agency workers when demand volatility is high while the opposite holds for...

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...

Perhaps no other country in recent years has witnessed greater change in its collective bargaining framework than the UK. This paper describes the dramatic developments and their consequences. Like Gaul, it is in three parts. The first part charts the six major pieces of legislation –...

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...

This study provides updated evidence on the union contract differential in Germany using establishment-wide wage data and two estimation strategies. It provides pairwise estimates of the union differential based on separate samples of collective bargaining leavers and joiners vis-à-vis the...

Using linked employer-employee data, this paper estimates the effect of collective bargaining coverage on wages over an interval of continuing decline in unionism. Unobserved firm and worker heterogeneity is dealt with using two establishment sub-samples, comprising collective bargaining joiners...

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...

German law guaranteeing works councils is not a datum. The thrust of legislation has changed significantly on a number of occasions since 1920. The most recent legal change in the form of the Works Constitution Reform Act marks a controversial swing in favor of works council formation and...
