This paper posits a notion of the value of an individual’s human capital and the associated return on human capital. These concepts are examined using U.S. data on male earnings and financial asset returns. We decompose the value of human capital into a bond, a stock and a residual value...

Is lifetime inequality mainly due to differences across people established early in life or to differences in luck experienced over the working lifetime? We answer this question within a model that features idiosyncratic shocks to human capital, estimated directly from data, as well as...

We provide theory for calculating bounds on both the value of an individual's human capital and the return on an individual's human capital, given knowledge of the process governing earnings and asset returns. The large idiosyncratic component of earnings risk implies that bounds on values and...

We analyze the Diamond-Saez policy recommendation within a human capital model. We calculate the steady-state welfare implications of raising the marginal income tax rate on top incomes from current levels to those in the range of 54 percent to 80 percent. We also calculate the transitional...

When does an individual's expected wealth accumulation profile increase as earnings risk increases? This paper answers this question for multi-period models where earnings shocks are independent over time. Sufficient conditions are stated in terms of properties of a decision rule for savings...
