In an intensively discussed paper, Andreoni and Sprenger (2012) , henceforth A&S, present an experiment where subjects can allocate money between two different points of time under the condition of risk. A&S claim that their results refute discounted expected utility (DEU) as well as prospect...

Banks should evaluate whether a borrower is likely to default. The author applies several techniques in the extensive mathematical literature of stochastic optimal control/dynamic programming to derive an optimal debt in an environment where there are risks on both the asset and liabilities...

In this paper we analyze theoretically and empirically the impact of an increase in income inequality on the current account balance. We develop a model with consumption externalities and heterogeneous agents which explains how an increase in income inequality can affect negatively or positively...

Aphorisms that "Rising tides raise all boats" or that material advances of the rich eventually "Trickle Down" to the poor are really maxims regarding the nature of stochastic processes that underlay the income/wellbeing paths of groups of individuals. This paper looks at the implications for the...

We construct a Blanchard-style overlapping generations model consisting of long-lived individuals who have uninsurable idiosyncratic risk resulting from uncertain retirement periods and medical costs in retirement. Without social insurance, such individuals must save for these eventualities. We...

Much analysis in macroeconomics empirically addresses economy-wide incentives behind consumer/investment choices by using insights from the way a single representative household would behave. Heterogeneity at the micro level can jeopardize attempts to back up the representative consumer...

Based on the aggregation of individual willingness-to-pay for a statistical life, we calibrate an intertemporal optimization model to determine the aggregate welfare losses from HIV/AIDS in 25 Eastern European countries. Assuming a discount rate of three percent, we find a total welfare loss for...

This paper analyzes insurance demand under prospect theory in a simple model with two states of the world and fair insurance contracts. We argue that two different reference points are reasonable in this framework, state-dependent initial wealth or final wealth after buying full insurance....
