Standard portfolio advice is that agents should hold a constant share of risky assets. All agents cannot, however, follow this advice because supply and demand of risky assets must be equal. To study equilibrium rebalancing, the paper develops an overlapping generations model in which agents...

The effect of Social Security rules on the age people choose to retire can be critical in evaluating proposed changes to those rules. This research derives a theory of retirement that views retirement as a special type of labor supply decision. This decision is driven by wealth and substitution...

Labor supply is unresponsive to permanent changes in wage rates. Thus, income and substitution effects cancel, but are they both close to zero or both large? This paper develops a theory of labor supply where income and substitution effects cancel, taking into account optimization over time,...

Individuals' preferences underlying most economic behavior are likely to display substantial heterogeneity. This paper reports on direct measures of preference parameters relating to risk tolerance, time preference, and intertemporal substitution. These experimental measures are based on survey...

Survey measures of preference parameters provide a means for accounting for otherwise unobserved heterogeneity.This paper presents measures of relative risk tolerance based on responses to survey questions about hypothetical gambles over lifetime income.It discusses how to impute estimates of...
