This paper discusses the recent research on the consumption function that has attempted to relax the assumption of certainty equivalence. While there remain many open questions, both theoretical and empirical, it is clear that the assumption of certainty equivalence can be misleading. Under more...

This paper focuses on Social Security benefit claiming behavior, a take-up decision that has been ignored in the previous literature. Using financial calculations and simulations based on an expected utility maximization model, we show that delaying benefit claim for a period of time after...

When the cost of a suit exceeds the expected judgment, will a potential plaintiff be able to extract any amount in settlement from the defendant? If so, what is the source of the plaintiff's ability to extract a settlement? This essay discusses existing theories as to why (and when) plaintiffs...

This paper considers the appropriate stabilization objectives for monetary policy in a microfounded model with staggered price-setting. Rotemberg and Woodford (1997) and Woodford (2002) have shown that under certain conditions, a local approximation to the expected utility of the representative...

Among the most important changes brought about by the Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (PRWORA) is the imposition of time limits. In this paper, we analyze a simple model in which a potential welfare recipient chooses how to allocate her time-limited...

Nearly all life-cycle models adopt Yaari's (1965) assumption that individuals know the survival probabilities that they face. Given that an individual's exact survival probabilities are likely unknown, we explore the implications of relaxing this assumption. If there is no annuity market, then...

Even if an asset has no fundamental uncertainty with a constant dividend process, a stochastic sentiment-driven equilibrium for the asset price exists besides the well-known fundamental equilibrium. Our paper constructs such sentiment-driven equilibria under general utility functions within an...
