We develop a tractable equilibrium asset pricing model with Cumulative Prospect Theory (CPT) preferences. Using GMM on a sample of U.S. equity index option returns, we show that by introducing a single common probability weighting parameter for both tails of the return distribution, the CPT...

We propose a new asset pricing model which generalizes the mean-variance framework by including probability weighting, specifically the overweighting of rare, high-impact events. Our model—the Π-CAPM—allows for disentangling volatility and skewness effects and predicts that idiosyncratic...
