We provide revealed preference axioms that characterize models of translation invariant preferences. In particular, we characterize the models of variational, maxmin, CARA and CRRA utilities. In each case we present a revealed preference axiom that is satisfied by a dataset if and only if the dataset is consistent from the corresponding utility representation.

The interesting implication is that the observation that PSDF elasticity must be around −50 holds for any prefer- ence specification to which our framework applies, not only for time-separable CRRA preferences. Hence the search for preferences that generate a high enough Sharpe ratio can be reduced to a search for preferences with a PSDF ...

In the first essay, we analyze the welfare effects of an unfunded social security system. We do so using an overlapping generations economy wherein agents have self-control preferences, face mortality risk, individual income risk, and borrowing constraints. Given our specification of preferences, unfunded social security helps reduce the agents' temptation to consume in every period ...

preferences whose measure of relative risk aversion is constant. These constant relative risk averse (CRRA) risk preferences are represented by a utility function of the power function form. This utility function is given by u(x) = 1-β x1 - β, where β is the level of relative risk aversion, and A(x) = x β is the absolute risk aversion measure.

New approach to eliciting risk preferences by framing risky choice as a satisficing task is proposed • Acceptable worst-case outcomes are traded off against best-case outcomes • New analytic links between satisficing and expected utility theory (EUT) under the assumptions of CARA and CRRA preferences •

Downloadable! This paper suggests a new approach for Portfolio Choice. In this framework, the investor, with CRRA preferences, has two objectives: the maximization of the expected utility and the minimization of the portfolio expected illiquidity.

In this paper, I elicit risk attitudes of U.S. executives by calibrating a subjective option valuation model for option exercising data (1996 to 2008), yielding approximately 65,000 values of relative risk aversion (RRA) for almost 7,000 executives. The observed behavior is generally consistent with moderate risk aversion and a median (mean) RRA close to one (three).

4/12/2016 · CARA and CRRA preferences are extremely common in applied work in macroeconomics and finance, among other fields. The authors of refs. 8, 9, and 10 carried out exercises similar to ours, also focusing on financial market experiments, but in a context of risk, not uncertainty. The closest papers to ours are those given in refs.

Investors generally dislike the risk of losses during bad times. Optimal portfolio choice trades off these risks with the potential of returns. While mean-variance utility treats gains and losses symmetrically, other models of preferences allow investors to seek safety first, to weight the pain of losses more heavily than the benefit of gains, and to have their utility depend on their past ...

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Preferences are defined over payoffs that are contingent on a finite number of states representing a horse race (Knightian uncertainty) and a roulette (objective risk). The class of scale-invariant (SI) ambiguity-averse preferences, in a broad sense, is uniquely characterized by a multiple-prior utility representation.
