We investigate the optimal nonlinear wage and interest-income taxes with money as an asset, assuming that there are two types of labor, which are not perfect substitutes in production, and that each type is difficult for the policymaker to observe. It is shown that the optimal interest-income...

This paper examines retirement and related behavioral responses to policies that on average are actuarially neutral. Many conventional models predict that actuarially neutral policies will not affect retirement behavior. In contrast, our model allows those with high time preference rates to find...

This paper describes the correlations between inequality and the growth rates in cross-country data. Using non-parametric methods, we show that the growth rate is an inverted U-shaped function of net changes in inequality: Changes in inequality (in any direction) are associated with reduced...

By 1992, pensions and retiree health insurance represented one quarter of the wealth of families on the verge of retirement. Our simulations suggest that between 1969 and 1992, abstracting from the effects of changes in wages and years of covered work on pension benefit amounts, changing pension...

In this paper we use indirect inference to estimate a joint model of earnings, employment, job changes, wage rates, and work hours over a career. Our model incorporates duration dependence in several variables, multiple sources of unobserved heterogeneity, job-specific error components in both...

Interest in economic mobility stems largely from its perceived role as an equalizer of opportunities, though not necessarily of outcomes. In this paper we show that this view leads very naturally to a methodology for the measurement of social mobility which has strong parallels with the theory...
