This paper makes two contributions to the literature on equilibrium search models. We cast the problem of determining the number of productivity types into a search for modes of the wage distribution and we use recent techniques of mode hunting to estimate the number and location of these modes.

Stimulus-response (SR) and belief-based learning (BBL) models are estimated with experimental data from sender-receiver games and compared using the Davidson and MacKinnon P-test for non-nested hypotheses. Depending on a certain adjustment parameter, the P-test favors the SR model, the BBL model...

This paper applies an equilibrium search to study the transition from schooling to work of US high school graduates. We consider the case where there is heterogeneity in firm productivity and the number of firm types is discrete. For this case the estimation problem is non-standard and the...
