Job differentiation gives employers market power, allowing them to pay workers less than their marginal productivity. We estimate a differentiated jobs model using application data from Careerbuilder.com. We find direct evidence of substantial job differentiation. Without the use of instruments...

This paper evaluates a class of endogenous job destruction models based on how well they explain the observed experiences of displaced workers. We show that pure reallocation models in which relationship-specific productivity drifts downward over time are difficult to reconcile with the evidence...

This paper measures excess labor supply in equilibrium. We examine hiring shocks--which employ 24% of the labor force in external month-long jobs--in Indian local labor markets. In peak months, wages increase instantaneously and local aggregate employment declines. In lean months, consistent...

I study unemployment insurance (UI) in general equilibrium with incomplete markets, search frictions, and nominal rigidities. An increase in generosity raises the aggregate demand for consumption if the unemployed have a higher marginal propensity to consume (MPC) than the employed or if agents...

This paper summarizes the results of nearly a dozen new papers presented at the Sundance Conference on Monopsony in Labor Markets held in October 2018. These papers, to be published as a special issue of the Journal of Human Resources, study various aspects of monopsony and failures of...

We study the labor markets in China and the United States, the two largest economies in the world, by examining the evolution of their cross-sectional age-earnings profiles during the past thirty years. We find that, first, the peak age in the cross-sectional age-earnings profiles, which we...

This paper examines the macroeconomic properties of imperfectly competitive economies. The focus is on the coordination failures that might arise in these economies, a study of alternative policies and the comparative static properties of these models. This paper differs from others in this area...

In the most widely analyzed type of efficiency wage model of involuntary unemployment, firms pay wages in excess of market clearing to give workers an incentive not to shirk. Such payments in excess of market clearing and the resultant equilibrium unemployment act as a worker discipline device....

7mplicit contracts resolve the distribution of uncertainty and utilization of specific human capital between risk averse workers and less risk averse firms. Incomplete contracts are required to yield involuntary layoffs in contract markets: otherwise, contracts are efficient and pareto optimal...

This paper exposits the modern theory of equalizing differences,viewed as optimal assignments of workers to jobs. The basic ideas are first illustrated in a simple model with binary choices of work attributes.Multinominal choices are briefly considered after that. Empirical implications are...
