We present a model in which temporary shocks can permanently scar the economy's productive capacity. Unemployed workers lose skill and are expensive to retrain, generating multiple steady state unemployment rates. Large temporary shocks push the economy into a liquidity trap, generating...

A large and growing share of hires in the United States are replacement hires. This increase coincides with a growing productivity-wage gap. We connect these trends by building a model where firms post long-lived vacancies and engage in on-the-job search for more productive workers. These...

We provide an information-based theory of matching efficiency fluctuations. Rationally inattentive firms have limited capacity to process information and cannot perfectly identify suitable applicants. During recessions, higher losses from hiring unsuitable workers cause firms to be more...

We analyze monetary policy in a model where temporary shocks can permanently scar the economy's productive capacity. Unemployed workers' skill losses generate multiple steady-state unemployment rates. When monetary policy is constrained by the zero bound, large shocks reduce hiring to a point...
