We present a model in which efficient long-term employment relationships are sustained by wage adjustments prompted by productivity shocks and outside job offers. These wage adjustments occur only sporadically, due to the presence of renegotiation costs. The model is amenable to analytical...

At the onset of the COVID pandemic, the U.S. economy suddenly and swiftly lost 20 million jobs. Over the next two years, the economy has been on the recovery path. We assess the labor market two years into the COVID crisis. We show that early employment dynamics were almost entirely driven by...

This paper evaluates the impact of slowing economic growth on labor market dynamism and misallocation. It provides a model of endogenous growth via imitation in a frictional labor market. The framework accounts for rich data on worker job-to-job transitions as well as stochastic and lifecycle...

Do recessions speed up or impede productivity-enhancing reallocation? To investigate this question, we use U.S. linked employer-employee data to examine how worker flows contribute to productivity growth over the business cycle. We find that in expansions high-productivity firms grow faster...

We develop a frictional labor market model with multiple regions and heterogeneous firms to study how frictions impeding labor mobility across space affect the joint allocation of labor across firms and regions. Bringing the model to matched employer-employee data from Germany, we find that...
