Previous empirical work on job search has proposed different approaches to estimating mobility rates assumed in models of search. However, these methods either only work for specific models of wage determination, or else require that we know the initial distribution of productivity for workers in our sample. In this paper we show it is possible to estimate mobility rates without having to restrict attention to models in which wages are constant over the course of a job or to assume that the initial distribution of productivity is known. More generally, the approach we propose allows us to freely estimate one degree of unobserved heterogeneity, be it in initial conditions or mobility rates. Applying our results to data from the NLSY suggests that the theoretical restrictions on the initial distribution of productivity implied by the standard model can overstate the extent of frictions to upward mobility.

This paper extends previous work on the identification of search models in which observed worker productivity is imperfectly observed. In particular, it establishes that these models remain identified even when employment histories are left-censored (i.e. we do not get to follow workers from their initial job out of unemployment), as well as when workers set different reservation wages from one another. We further show that allowing for heterogeneity in reservation can affect the empirical estimates we obtain, specifically estimates of the rate at which workers receive job offers.
