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...

After a brief summary of Ben Porath's 1967 model approach, I enquire into the empirical validity and some implications of his insights. Section 2 is an attempt to answer the question: Are the shapes and magnitudes of growth in wage profiles largely attributable to human capital investments?...

The purpose of this paper is to consider human capital models of earning behavior over an individual lifetime. A general class of life cycle models relating to individual earnings behavior is developed by considering alternative formulation of the basic Ben- Porath type model. An explicit...

This paper re-examines the classic question of how a household should optimally allocate its portfolio between risky stocks and risk-free bonds over its lifecycle. We show that allowing for the wage indexation of social security benefits fundamentally alters the optimal decisions. Moreover, the...

This paper incorporates two empirically-grounded insights into a dynamic life cycle portfolio choice model: the fact that investors forego the opportunity to accumulate job-specific skills when they spend time managing their own money, and the observation that efficiency in financial decision...

This paper derives optimal life cycle portfolio asset allocations as well as annuity purchases trajectories for a consumer who can select her hours of work and also her retirement age. Using a realistically-calibrated model with stochastic mortality and uncertain labor income, we extend the...

We investigate optimal consumption, asset accumulation and portfolio decisions in a realistically calibrated life-cycle model with flexible labor supply. Our framework allows for wage rate uncertainly, variable labor supply, social security benefits and portfolio choice over safe bonds and risky...

We analyze consumption and portfolio behavior in a life-cycle model with realistic borrowing costs and income processes. We show that even a small wedge between borrowing costs and the risk-free return dramatically shrinks the demand for equity. When the cost of borrowing equals or exceeds the...

Empirical studies of the life cycle savings model have tended to rej ect the hypothesis of a quot;hump-shapedquot; pattern for the wealth-age profile. In this paper we show, using new data on net worth for 12,734 families, that there is evidence that wealth declines after retirement provided...
