Toward understanding assortative matching, this is a self-contained introduction to research
on search and matching. We first explore the nontransferable and perfectly transferable …

We propose leave‐out estimators of quadratic forms designed for the study of linear models
with unrestricted heteroscedasticity. Applications include analysis of variance and tests of …

We propose a framework to identify and estimate earnings distributions and worker
composition on matched panel data, allowing for two‐sided worker‐firm unobserved …

Using administrative German data, we show that large cities allow for a more efficient
matching between workers and firms and this has important consequences for geographical …

Rent-sharing by workers can reduce the incentives for investment if some of the returns to
sunk capital are captured in higher wages. We propose a simple measure of this “holdup” …

We estimate an equilibrium on-the-job search model with endogenous search intensity.
Workers differ by skill, firms by productivity. Workers respond to mismatch by intensive …

We assess the empirical content of equilibrium models of labor market sorting based on
unobserved (to economists) characteristics. In particular, we show theoretically that all …

We present evidence that is consistent with large disparities across firms in their on-the-job
learning opportunities, using administrative datasets from Brazil and Italy. We categorize …

The quality of an employment match is a central concept in labour economics. It is relevant
for evaluating the welfare impact of labour market policies, and for our understanding of …

The process of matching between firms and workers is an important mechanism in
determining the distribution of wages. In a labor market characterised by large dispersion of …
