Job changes and individual-job specific wage dynamics

This paper develops an error components model that is used to examine the impact of job changes on the dynamics and variance of individual log earnings. I use data on work histories drawn from the Panel Study of Income Dynamics (PSID), that makes possible to do the distinction between voluntary an involuntary job-to-job changes. The potential endogeneity of job mobility in relation to earnings es circumvented by means of an instrument variable estimation method that also allows to control for unobserved individual-job specific heterogeneity.
