Tenure Proﬁles and Eﬃcient Separation in a Stochastic Productivity Model, forthcoming in Journal of Business and Economic Statistics, also as CELSI DP No. 7
The authors develop a theoretical model based on efficient bargaining, where both log outside productivity and log productivity in the current job follow a random walk. This setting allows the application of real option theory. They derive the efficient worker-ﬁrm separation rule and show that wage data from completed job spells are uninformative about the true tenure proﬁle. The model is estimated on the PSID. It ﬁts the observed distribution of job tenures well. Selection of favourable random walks can account for the concavity in tenure proﬁles. About 80% of the estimated wage returns to tenure is due to selectivity in the realized outside productivities.
