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...

Using a multi-dimensional measure of occupational mismatch, we report distinct gender differences in match quality and changes in match quality over the course of careers. A substantial portion of the gender wage gap stems from match quality differences among more educated individuals....

Job mobility, especially early in a career, is an important source of wage growth. This effect is typically attributed to heterogeneity in the quality of employee-employer matches, with individuals learning of their abilities and discovering the tasks at which they are most productive through...

We model how investors allocate between asset managers, managers choose their portfolios of multiple securities, fees are set, and security prices are determined. The optimal passive portfolio is linked to the “expected market portfolio,” while the optimal active portfolio has elements of...

Despite recent changes in the relationship between unionism and various indicators of firm performance, there is one seeming constant in the Anglophone countries: unions at the workplace are associated with reduced employment growth of around -2.5% a year. Using German data, we examine the...

This paper examines the pattern of employment adjustment in Portugal. First, the issue is addressed using a long time series of aggregate data. Although the employment data show persistence, there is nonetheless a fairly rapid rate of employment adjustment. Second, a much shorter time series of...
