Research Topics

The role of higher moments in hedging under transactions costs (with Miao Chen)
A local time analysis of delta hedginghunder transactions costs reveals that the higher moments of the probability distribution of the costs incurred influence the width of the hedging band.
The value of a storage facility
The paper derives the value of a facility to store a commodity whose exogenously defined price process has both seasonal and mean-reverting components. It provides an elegant new analytic continuous-time model of storage. Closed form solutions are obtained as functions of the underlying price (when there is no seasonality), and a local time analysis provides an even simpler unconditional formula which extends to the general case. An interesting feature is that both buy and sell transactions are triggered by a single critical price. The analysis provides insights into the profitability of storing under alternative price process assumptions.
Fixed odds bookmaking with stochastic betting demands (with Hao Lin)
This paper studies the fixed odds bookmaking in the market for bets in a British horse race. The bookmaker faces the risk of unbalanced liability exposures. Even random shocks in the noisy betting demands are costly to the bookmaker since his book could become less balanced. In our model, the bookmaker sets appropriate odds to influence the betting flow to mitigate the risk. The stylized fact of the favorite-longshot bias only arises from the model under specific assumptions. Our model offers insights into the complexity of managing a series of state contingent exposures such as options.
