Asset Pricing with Loss Aversion∗
نویسندگان
چکیده
Using standard preferences for asset pricing has not been very successful in matching asset price characteristics such as the risk-free interest rate, equity premium and the Sharpe ratio to time series data. Behavioral finance has recently proposed more realistic preferences such as those with loss aversion. Research is starting to explore the implications of behaviorally founded preferences for asset price characteristics. Encouraged by some studies of Benartzki and Thaler (1995) and Barberis et al. (2001) we study asset pricing with loss aversion in a production economy. Here, we employ a stochastic growth model and use a stochastic version of a dynamic programming method with adaptive grid scheme to compute the above mentioned asset price characteristics of a model with loss aversion in preferences. As our results show using loss aversion we get considerably better results than one obtains from pure consumption-based asset pricing models including the habit formation variant.

Consumption-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...
متن کاملExamination of Equity Premium Puzzle by Consumption Capital Asset Pricing Model with Fuzzy Nested Regimes: Evidence from Iran
The aim of this study is to examine the equity premium puzzle in Iran for the quarterly period of 1993-2016. In this regard, the hybrid bivariate Garch model and also fuzzy dummy variables with consumption capital asset pricing model (C-CAPM) have been used. The results of study show that using C-CAPM within fuzzy dummy variables (CCAPM-F), the relative risk aversion coefficient of investor is ...
متن کاملInvestigating the Role of real Money Balances in Households' Preferences function in the Framework of the Assets Pricing Models (M-CCAPM): Case study of Iran
In this paper, we try to develop and modify the basic model of the consumption-based capital asset pricing model by adding the growth in real money balances rate as a risk factor in the household's utility function as (M-CCAPM). For this purpose, two forms of utility function with constant relative risk aversion (CRRA) preferences and recursive preferences have been used such that M1 and M2 are...
متن کامل“Asset Prices under Habit Formation and Reference-Dependent Preferences”
This article explains the high level and the countercyclical variation of the equity premium in a consumption-based asset pricing model with low large-scale risk aversion. Investors have gain-loss utility over consumption relative to slowly time-varying habit. Stocks deliver low returns in recessions when consumption falls below habit; investors therefore require a high premium for holding stoc...
متن کاملTime-Varying Preferences and SAD: Evidence from an Asset-Pricing Model∗
We investigate a representative agent consumption-based asset pricing model with two states: low risk aversion and high risk aversion. We explore whether there is a reasonable parameterization capable of generating the empirically observed seasonally-varying equity and Treasury returns documented by Kamstra, Kramer, and Levi (2008). Calibrating the asset-pricing model to observed consumption da...
