چکیده

We study asset prices in an economy where investors derive direct utility not only from consumption but also from uctuations in the value of their Žnancial wealth. They are loss averse over these uctuations, and the degree of loss aversion depends on their prior investment performance. We Žnd that our framework can help explain the high mean, excess volatility, and predictability of stock returns, as well as their low correlation with consumption growth. The design of our model is inuenced by prospect theory and by experimental evidence on how prior outcomes affect risky choice.

Prospect Theory and the Law of Small Numbers in the Evaluation of Asset Prices

We develop a model of one representative agent and one asset. The agent evaluates the earnings according to Prospect Theory and he does not know exactly the stochastic process generating earnings. While the earnings are generated by a random walk process, the agent considers a Markovian process, according to which firm’s earnings move between two regimes, represented by a mean-reverting process...

Prospect Theory and Asset Pricing in an RBC Framework

We construct a fully-fledged production economy model with Kahneman and Tversky’s Prospect Theory features. The agents’ objective function is a weighted sum of the usual utility over consumption and leisure and the utility over the relative changes of the agents’ wealth. It is also assumed that the agents are more sensitive to wealth losses than to gains. Apart from the changes in the utility, ...

Prospect Theory and Stock Returns: An Empirical Test

We test the hypothesis that, when thinking about allocating money to a stock, investors mentally represent the stock by the distribution of its past returns and then evaluate this distribution in the way described by prospect theory. In a simple model of asset prices in which some investors think in this way, a stock whose past return distribution has a high (low) prospect theory value earns a ...
