Earnings Dynamics and Firm-Level Shocks

We use matched employer-employee data from Sweden to study the role of the Þrm in affecting the stochastic properties of wages. Our model accounts for endogenous participation and mobility decisions. We find that firm-specific permanent productivity shocks transmit to individual wages, but the effect is mostly concentrated among the high- skilled workers. The pass-through of temporary shocks is smaller in magnitude and similar for high- and low-skilled workers. The updates to worker-Þrm specific match effects over the life of a Þrm-worker relationship are small. Substantial growth in earnings variance over the life cycle for high-skilled workers is driven by Þrms. In particular, cross-sectional wage variances by age 55 are roughly one- third higher relative to a scenario with no pass-through of Þrm shocks onto wages.
