Firm Dynamics, On-the-Job Search, and Labor Market Fluctuations
Abstract
We devise a tractable model of firm dynamics with on-the-job search. The model admits analytical solutions for equilibrium outcomes, including quit, layoff, hiring and vacancy-filling rates, as well as the distributions of job values, a fundamental challenge posed by the environment. Optimal labor demand takes a novel form whereby hiring firms allow their marginal product to diffuse over an interval. The evolution of the marginal product over this interval endogenously exhibits gradual mean reversion, evoking a notion of imperfect labor market competition. This in turn contributes to dispersion in marginal products, giving rise to endogenous misallocation. Mirroring establishment microdata, quit and layoff rates fall, while hiring and vacancy-filling rates rise with firm growth in the model. We further show how it is possible to solve for the dynamic equilibrium path of model outcomes—including the distribution of job values—out of steady state.Bad Jobs and Low Inflation
Abstract
The low rate of inflation observed in the U.S. over the entire past decade is hard to reconcile with traditional measures of labor market slack. We show that an alternative notion of slack that encompasses workerspropensity to search on the job explains this missing inflation. We derive this novel concept of slack from a model in which a drop in the on-the-job search rate lowers the intensity of interfirm wage competition to retain or hire workers. The on-the-job search rate can be measured directly from aggregate labor-market flows and is countercyclical. Its recent drop is corroborated by micro data.Job Ladder and Business Cycles
Abstract
I study the aggregate implications of job-to-job flows in a Heterogeneous Agents New Keynesianmodel. Workers search on-the-job and cannot directly insure against the earnings risk
stemming from climbing and falling off the ladder. The state of the economy depends on the
distribution of workers over match productivity, earnings, and wealth. The job ladder is shown to have both supply and demand-side consequences over the business cycle: the employment reallocation over the ladder moves labor productivity in response to aggregate shocks, while workers’ demand for consumption reacts to changes in labor market flows. In the wake of an adverse financial shock, reallocation over the job ladder slows down, keeping workers stuck at low-productivity jobs. Aggregate productivity falls gradually over time, and drags down consumption and output even further. These patterns match the behavior of aggregates during and after the Great Recession, with the reduction in labor productivity explaining both the slow recovery and the missing disinflation.
