Job mobility and careers in firms

This paper presents a theoretical model that combines employers learning about worker productivity, human capital acquisition, job-assignment and resolution of worker uncertainty regarding disutility of work from a job, to show how widely documented findings on both wage and promotion dynamics and turnover can be captured in a single set-up. Specifically we show how our model can capture results such as; probability of turnover decreases with labor market experience, wage changes during job changes is more in earlier periods, serial correlation in wages and probability of promotion increases in wages, amongst others.
