We study a firm that justifies its novel use of equity derivatives as a cash-flow hedging strategy. Our purpose is to understand the challenge of translating risk management theory into managerial action. Cephalon Inc., a biotech firm, bought a large block of call options on its own stock. If...

This paper analyzes optimal portfolio choice and consumption with stochastic volatility in incomplete markets. Using the Duffie-Epstein (1992) formulation of recursive utility in continuous time, it shows that the optimal portfolio demand for stocks under stochastic volatility varies strongly...

This paper develops a simple approach to solving multi-period consumption and investment problems. All numerical methods in use for these types of problems work by solving the problem backward, i.e., solving the consumption and investment decision at the end of the investment horizon and working...

A great deal of work has focused on market microstructure, but relatively little work has been devoted to the study of risk associated with liquidity. The work that has been done has almost exclusively focused on US equities - primarily because that market is fairly liquid and therefore data is...

This paper derives a methodology for the exact estimation of continuous-time stochastic models based on the characteristic function. The estimation method does not require discretization of the process, and it is easy to apply. The method is essentially generalized method of moments on the...
