We develop a model of retirement and human capital investment to study the effects of tax and retirement policies. Workers choose the supply of raw labor (career length) and also the human capital embodied in their labor. Our model explains a significant fraction of the US-Europe difference in...

We propose an original model of human capital investments after leaving school in which individuals differ in their initial human capital obtained at school, their rate of return, their costs of human capital investments and their terminal values of human capital at a fixed date in the future....

This paper derives optimal income tax and human capital policies in a dynamic life cycle model of labor supply and risky human capital formation. The wage is a function of both stochastic, persistent, and exogenous "ability" and endogenous human capital. Human capital is acquired throughout life...

We hypothesize, and examine empirically, two types of association between organization capital and firm life cycle. Are firms with high organization capital more likely to be in a particular stage of their life cycle than firms with low organization capital? Are firms' transitions from one life...
