This paper studies the dynamics of labor demand at the plant and aggregate levels. The correlation of hours and employment growth is negative at the plant level and positive in aggregate time series. Further, hours and employment growth are about equally volatile at the plant level while hours...

We explore how the rapid adoption of computer-related assets affects the recent polarization of employment in the U.S. labor market, which is inconsistent with the skill-biased technological change hypothesis. Similar to Goos and Manning (2007), we show that the job polarization could be...

In order to simplify the representation of a technological relationship between inputs and outputs, a production unit's technology must typically satisfy some restrictive conditions, some of them being well known in the literature. This paper presents new results for aggregating labour inputs...

This paper develops and tests a new model of asymmetric information in the labour market involving employer learning. In the model, I provide theoretical conditions for the identification - based on the experience and tenure profiles of estimated returns to ability and education - of employer...

This paper develops a multi-period model, in which workers are matched with jobs according to imperfect educational signals and in which their subsequent productivities depend on both their inherent ability and on the quality of the job match. It outlines a sequential process, in which underpaid...

This paper studies the dynamics of labor demand at the plant and aggregate levels. The correlation of hours and employment growth is negative at the plant level and positive in aggregate time series. Further, hours and employment growth are about equally volatile at the plant level while hours...

This paper presents a model where wage differences between men and women arise from taste-based discrimination and monopsonistic mechanisms. We show how preferences against women affect heterogeneity in firms’ pay policies in the context of an imperfect labour market, deriving a test for the...
