We set up a model with on-the-job search in which firms infrequently post vacancies for which workers occasionally apply. The model nests the standard job ladder and stock-flow models as special cases, while remaining analytically tractable and easy to estimate from standard panel data sets. The...

Unemployment insurance schemes face a well-known trade-off between providing income support to those out of work and reducing their incentive to look for work. This trade-off between benefits and incentives is central to the public debate about extending benefit periods during the recent...

This paper develops a sufficient-statistic formula for the unemployment gap-the difference between the actual unemployment rate and the efficient unemployment rate. While lowering unemployment puts more people into work, it forces firms to post more vacancies and to devote more resources to...
