Markowitz’s challenge. We augment the Markowitz utility function with arguments that have roots in the theory of natural … selection: peer wealth, and status. Our specification yields testable implications about gambling, insuring and peer selection …

We report an experimental test of the four touchstones of rationality in choice under risk – utility maximization …, stochastic dominance, expected-utility maximization and small-stakes risk neutrality – with students from one of the best …

This chapter of a collective book aims at presenting the basics of decision making under risk. We first define notions … of risk and increasing risk and recall definitions and classifications (that are valid independently of any … representation) of behavior under risk. We then review the classical model of expected utility due to von Neumann and Morgenstern …

The economic theory of decision making under risk has seen remarkable advances over the 50 years since Pratt’s (1964 …) characterization of risk aversion under expected utility. We review developments in three key areas to which Louis Eeckhoudt has made … significant contributions: (1) increases in risk and risk taking; (2) self-protection and risk aversion; and (3) higher (and lower …

As in any research field, risk theory has its important questions, results, and paradoxes, as well as its seminal … papers and key authors. Louis Eeckhoudt has been a key author in the field of risk theory. To celebrate his many … contributions to the literature, and provides some illustrations of the remarkable research saga in risk theory over the last 50 …
