We estimate a dynamic programming model of schooling decisions in which the degree of risk aversion can be inferred … homogeneous with respect to the degree of risk aversion. We allow endogenous schooling attainments to affect the level of risk … experienced in labor market earnings through wage dispersion and employment rate dispersion. We find a low degree of relative risk …

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 theory of existence of equilibrium with short-selling is reconsidered under risk and ambiguity modelled by risk … of the risk adjusted sets of expectations overlap. This condition is necessary if agents are not risk neutral at extreme … compatible trades, with non negative expected value with respect to any risk adjusted prior, strictly positive for some agent and …

, which allow to take into account observed behaviors as in Allais' paradox under risk or Ellsberg's paradox under uncertainty … uncertainty, and Quiggin and Yaari under risk, succeeded to characterize preferences which generalize the EU model, by means of a … for more diversified patterns of behavior under uncertainty as well under risk. …
