We present an empirical analysis of job reallocation and labor mobility using matched worker-firm data for the Netherlands to investigate how firms adjust their workforce over the cycle. Our data cover the period 1993-2002. We find that cyclical adjustments of the workforce occur mainly through...

We present a Search and Matching model with heterogeneous workers (entrants and incumbents) that replicates the stylized facts characterizing the US and the Spanish labor markets. Under this benchmark, we find the Post-Match Labor Turnover Costs (PMLTC) to be the centerpiece to explain why the...

Using a novel database of 82.5 million online job postings, we show that employer skill requirements fell as the labor market improved from 2010 to 2014. We find that a 1 percentage point reduction in the local unemployment rate is associated with a roughly 0.27 percentage point reduction in the...

We present a Search and Matching model with heterogeneous workers (entrants and incumbents) that replicates the stylized facts characterizing the US and the Spanish labor markets. Under this benchmark, we find the Post-Match Labor Turnover Costs (PMLTC) to be the centerpiece to explain why the...

Although labor market "mismatch" often refers to an imbalances in supply and demand across occupations, mismatch within occupations can arise if skill requirements are changing over time, potentially reducing aggregate matching efficiency within the labor market. To test this, we examine changes...
