The Right Man for the Job - Increasing Returns in Search?
View PDF Version
This paper describes a search model with a continuum of worker and job types, transferable utility and an IRS contact technology. We apply a second order Taylor expansion to approximate an analytical solution of the equilibrium. We find that one third of the increasing returns in contacts are absorbed by firms and workers being more choosy. Hence, strongly increasing returns in contact rates are consistent with weakly increasing returns in matching. In addition, we derive and decompose the efficiency loss due to inadequate incentives and show how unemployment benefits can reduce the loss. Finally, we derive a relation between the size of the surplus due to search frictions and the degree of substitutability of worker types at given job complexity levels. Numerical simulations of the model show that our approximations are quite accurate.
