In the United States, many employees can save for retirement by participating in Defined Contribution Plans (DCPs). We propose a tractable framework for calculating the employee’s subjective value of the participation option. The framework allows us to separate multiple benefits of...

In response to how they are compensated, mutual fund managers who are under-performing by mid-year are likely to increase the risk of their portfolios towards the year-end. We argue that an increase in the liquidity of the stocks that managers use to shift risk can lead to an increase in the...

We consider superhedging of contingent claims under ratio constraint. It has been widely recognized that the minimum cost of superhedging a contingent claim with certain constraints is equal to the price of a dominating claim without constraints. In terms of the backward stochastic differential...

Extant theories on the disposition effect are largely silent on most of the related trading patterns, including the V-shape results for probabilities of buying and selling against unrealized profit. On the other hand, portfolio rebalancing and learning have been shown to be important, even for...

We examine the problem of an investor who trades in a market with unobservable regime shifts. The investor learns from past prices and is subject to transaction costs. Our model generates significantly larger liquidity premia compared to a benchmark model with observable market shifts. The...

We generate large liquidity premia endogenously from the interaction of transaction costs with convexity in preferences, offering a novel explanation for a longstanding puzzle. We derive this result from the dynamic portfolio problem of mutual fund managers facing either convex flows or year-end...
