Worker Selection

This paper incorporates worker selection into a random matching model with multi-worker firms. Unlike the standard Diamond-Mortensen-Pissarides (DMP) model, the extended model is compatible with cross-sectional behavior of vacancy yields, which rise with employment growth and worker turnover, but fall with establishment size. Using calibrated versions of the standard and worker selection models, I show that accounting for these patterns has quantitatively important policy implications. I also compare the worker selection and the directed search models. While both models account for these patterns equally well, they differ with regard to labor market policy.

Current State

We review theories of race discrimination in the labor market. Taste-based models can generate wage and unemployment duration differentials when combined with either random or directed search even when strong prejudice is not widespread, but no existing model explains the unemployment rate differential. Models of statistical discrimination based on differential observability of productivity across races can explain the pattern and magnitudes of wage differentials but do not address employment and unemployment. At their current state of development, models of statistical discrimination based on rational stereotypes have little empirical content. It is plausible that models combining elements of the search models with statistical discrimination could fit the data. We suggest possible avenues to be pursued and comment briefly on the implication of existing theory for public policy. (JEL J15, J31, J64, J71)

A NOTE ON MONOTONE COMPARATIVE STATICS FOR MONETARY DIRECTED SEARCH MODELS

The Impact

This note uses monotone methods to derive two sets of comparative statics results for monetary directed search models. First, it characterizes the impact of a higher inflation rate or a higher cost of using credit on market outcomes, regardless of the choice of matching function. Second, the seller-to-buyer ratio, output level, and money demand increase as the matching function becomes more efficient in a log-supermodular sense. I also consider an extension with endogenous search intensity and show that search intensity and trade volume always decrease in the nominal interest rate.
