Prospect theory (PT) has long been linked with the disposition effect. Despite significant progress towards rigorously modeling the trading behavior of PT investors, the literature has been largely silent on the effect of probability weighting. In this paper we incorporate probability weighting...

We study Cautious Stochastic Choice (CSC) agents facing optimal timing decisions in a dynamic setting. In an expected utility setting, the optimal strategy is always a threshold strategy - to stop/sell the first time the price process exits an interval. In contrast, we show that in the CSC...

This paper investigates option prices in an incomplete stochastic volatility model with correlation. In a general setting, we prove an ordering result which says that prices for European options with convex payoffs are decreasing in the market price of volatility risk.As an example, and as our...

Is there any point to which you would wish to draw my attention? To the curious incident of the investment in the market. The agent did nothing in the market. That was the curious incident. (with apologies to Sir Arthur Conan-Doyle.)In this paper we study an optimal timing problem for the sale...
