This paper presents and estimates a unified model where both human capital investment and job search are endogenized. This unification enables us to quantify the relative contributions of each mechanism to life cycle earnings growth, while investigating potential interactions between human...

How does the persistence of earnings change over the life cycle? Do workers at different ages face the same variance of idiosyncratic shocks? This paper proposes a novel specification for residual earnings that allows for an age profile in the persistence and variance of labor income shocks. We...

Analyses of savings rates needed for successful retirement rates (SSRs) typically assume constant real earnings growth throughout one's career. However, data on the life-cycle earnings patterns of millions of U.S. workers suggest that earnings growth does not occur at a constant rate that...
