Résumé / Abstract A l'aide de données sur la consommation des ménages et d'équations d'Euler, cet article estime le taux d'aversion au risque relatif. Ces équations d'Euler sont les implications de structures de marché qui ne permettent pas toujours aux agents de s'assurer parfaitement. Cet article porte plus particulièrement sur des tests de l'équation d'Euler inconditionnelle. Dans le cadre d'un agent représentatif, ce type de test mène aux rejets les plus intuitivement convaincants des modèles d'évaluation d'actifs, comme l'énigme de la prime de risque et l'énigme du taux sans risque. Lorsque l'on ignore les erreurs de mesure de la consommation, les erreurs de l'équation d'Euler ne sont pas statistiquement différents de zéro pour les valeurs du taux d'aversion au risque relatif comprises entre 1 et 3. Lorsque l'on tient compte de la présence des erreurs de mesure, les estimations conservatrices du taux d'aversion au risque relatif pour les participants à un marché d'actifs indiquent une valeur entre 2 et 8. Ces résultats suggèrent que le taux d'aversion au risque pourrait être plus bas que ce qui est couramment perçu. Par conséquent, l'imperfection des marchés pourrait servir à résoudre les énigmes d'évaluation d'actifs. This paper estimates the rate of relative risk aversion using Euler equations based on household-level consumption data. These Euler equations are implications of market structures that do not necessarily allow agents to perfectly insure themselves. The paper focuses on tests of the unconditional Euler equation. In representative-agent frameworks, this type of test leads to the most intuitively convincing rejections of asset-pricing models, such as the equity premium puzzle and the riskfree rate puzzle. When measurement error in consumption is ignored, …

Risk premiums and certainty equivalents of loss-averse newsvendors of bounded utility
Loss-averse behavior makes the newsvendors avoid the losses more than seeking the probable gains as the losses have more psychological impact on the newsvendor than the gains. In economics and decision theory, the classical newsvendor models treat losses and gains equally likely, by disregarding the expected utility when the newsvendor is loss-averse. Moreover, the use of unbounded utility to m...
متن کاملDo You Reward and Punish In The Way You Think Others Expect You To?
This paper addresses three questions: (1) When deciding on whether to reward or punish someone, how does how you think others expect you to behave affect your decision? (2) Does it depend upon whether others expect you to reward them vs. punish them? (3) What is the interpretation of such a causal effect? We investigate these questions using a modification of the lost wallet trust game (Dufwenb...

متن کاملConsumption-Based Asset Pricing with Recursive Utility
In this paper it has been attempted to investigate the capability of the consumption-based capital asset pricing model (CCAPM), using the general method of moment (GMM), with regard to the Epstien-zin recursive preferences model for Iran's capital market. Generally speaking, recursive utility permits disentangling of the two psychologically separate concepts of risk aversion and elasticity of i...
