This paper solves a real business cycle model with heterogeneous agents and uninsurable income risk using perturbation methods. A second order accurate characterization of agent's optimal decision rules is given, which renders the implications of aggregation for macroeconomic dynamics...

This paper accepts for the sake of argument the hypothesis that much of the time series correlation between tax and profit rates is spurious, and shows how nonetheless time series for profit rates, tax rates, and consumption can be organized, compared and interpreted using Fisher's (1930) theory...

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...

In recent decades, the US wage structure has been transformed by a rising college premium, a narrowing gender gap, and increasing persistent and transitory residual wage dispersion. This paper explores the implications of these changes for cross-sectional inequality in hours worked, earnings and...

This paper compares the dynamics of two general equilibrium models of endogenous growth in which agents have comparison utility.' In the inward-looking' economy, individuals care about how their consumption in the current period compares to their own consumption in the past (one way to describe...

This study demonstrates how constrained efficient allocations can arise endogenously as equilibria in an economy with a limited ability to enforce contracts and with private agents behaving competitively, taking a set of taxes as given. The taxes in this economy limit risk-sharing and arise in...

This paper employs a simple intertemporal model to show that presence of liquidity constraints can depress the price of a durable good below its net present rental value, regardless of the overall supply elasticity. The existence of price effects implies that the relaxation of liquidity...

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...

Economic theory assigns a central role to risk preferences. This paper develops a measure of relative risk tolerance using responses to hypothetical income gambles in the Health and Retirement Study. In contrast to most survey measures that produce an ordinal metric, this paper shows how to...
