Firm heterogeneity and worker turnover

Previous empirical analyses of job mobility focus on worker rather than firm characteristics. This paper exploits a unique data set on enterprise employment. We describe sectoral differences in turnover rates and in the persistence of turnover. We also present evidence of persistent turnover differences at the level of the individual firms—a result that is expected if firms have managers with differing ability to screen workers. When we consider the consequences to the firm of such turnover, we discover that high turnover firms are less likely to survive.     

Do Borrowing Constraints Change U.S. Homeownership Rates?

This study has two main objectives. First, we estimate various alternative specifications of the tenure choice model with borrowing constraint variables, originally put forth by Linneman and Wachter, using a more recent sample of the Survey of Consumer Finance. Second, we simulate effects of policy changes governing constraints and changes in mortgage interest rates, both on households' owning decisions and on the aggregate homeownership rate. While the impact of constraints has been demonstrated in previous studies, our research provides the first microsimulation estimates of the impact for aggregate homeownership rates for the entire U.S. population.     

Nash as an Organizing Principle in the Voluntary Provision of Public Goods: Experimental Evidence

Experiments are reported that add to the growing literature on the voluntary provision of public goods. Information conditions are manipulated to address whether early findings of above-equilibrium contributions to a public good are a result of complete information regarding the symmetry of the game. No significant information effect was found. Further, by examining designs with an interior Nash equilibrium, this research suggests that the nonzero contributions observed in the previous dominant strategy environments, where the prediction was a zero level of provision of the public good, were not simply transitional errors as the system converged to a boundary equilibrium.

Market share and price rigidity

Survey evidence shows that the main reason why firms keep prices stable is that they are concerned about losing customers or market share. We construct a general equilibrium model in which firms care about the size of their customer base. Firms and customers form long-term relationships because consumers incur costs to switch sellers. In an environment with sectoral productivity shocks, we show that cost pass-through is a non-monotonic function of the size of switching costs. Specifically, prices tend to become more stable as the fraction of repeat customers increases and the elasticity of the customer base falls.
