چکیده

In this paper, we consider the relationship between supermodularity and risk aversion. We show that supermodularity of the certainty equivalent implies that the certainty equivalent of any random variable is less than its mean. We also derive conditions under which supermodularity of the certainty equivalent is equivalent to aversion to mean-preserving spreads in the sense of Rothschild and Stiglitz. © 2006 Elsevier B.V.

Supermodularity is not Falsifiable∗

Supermodularity has long been regarded as a natural notion of complementarities in individual decision making; it was introduced as such in the nineteenth century by Edgeworth and Pareto. But supermodularity is not an ordinal property. We study the ordinal content of assuming a supermodular utility, i.e. what it means for the individual’s underlying preferences. We show that supermodularity is ...

Prudence, temperance, edginess and higher degree risk apportionment as decreasing correlation aversion

This paper shows that the notions of prudence, temperance, edginess, and, more generally, risk apportionment of any degree are the consequences of the natural idea that the sensitivity to detrimental changes should decrease with initial wealth. In the setting of Epstein & Tanny (1980), this turns out to be equivalent to the supermodularity of the expected utility for some specific 4-state lotte...

Monotone Comparative Statics under Uncertainty

This paper analyzes monotone comparative statics predictions in several classes of stochastic optimization problems. The main results characterize necessary and sufficient conditions for comparative statics predictions to hold based on properties of primitive functions, that is, utility functions and probability distributions. The results apply when the primitives satisfy one of the following t...

Surplus Maximization and Optimality

I identify assumptions under which policies that maximize expected surplus are Pareto Optimal–even when expected consumer surplus does not even locally represent preferences over price-income lotteries. Besides the oft-made partial equilibrium assumptions that only one price varies, and that income changes do not affect demand, the two other assumptions are that every consumer’s indirect utilit...
