In the context of extreme climate change, we ask how to conduct expected utility analysis in the presence of catastrophic risks. Economists typically model decision making under risk and uncertainty by expected utility with constant relative risk aversion (power utility); statisticians typically...

This note proposes the Burr utility function. Burr utility is a flexible two-parameter family that behaves approximately power-like (CRRA) remote from the origin, while exhibiting exponential-like (CARA) features near the origin. It thus avoids the extreme behavior of the power family near the...

We explicitly derive and explore the optimal consumption and portfolio policies of a loss- averse individual who endogenously updates his reference level over time. We find that he protects his current consumption by delaying painful reductions in consumption after a drop in wealth, and...

This paper explores the joint impact of reference-dependent preferences and non- tradable risky labor income on optimal savings and portfolio decisions. We develop a non-trivial solution procedure to determine the optimal policies. Our results reveal that the impact of permanent labor income...
