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...

In early 1997, Cephalon, Inc., a biotechnology firm, purchased 2.5 million capped call options on its own stock, with a potential value of as much as $45 million, in exchange for $9.8 million worth of its common shares. Cephalon's first major drug, Myotrophin, was under review by the U.S. Food...

This paper models transaction costs as the rents that a monopolistic market maker extracts from impatient investors who trade via limit orders. We show that limit orders are American options. The limit prices inducing immediate execution of the order are functionally equivalent to bid and ask...

We present a new measure of liquidity known as "latent liquidity" and apply it to a unique corporate bond database. Latent liquidity is defined as the weighted average turnover of investors who hold a bond, in which the weights are the fractional investor holdings. It can be used to measure...

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 examines the optimal consumption and portfolio choice problem of long-horizon investors who have access to a riskless asset with constant return and a risky asset (‘stocks’) with constant expected return and time varying precision – the reciprocal of volatility. Markets are...

This Paper derives an approximate solution to a continuous-time intertemporal portfolio and consumption choice problem. The problem is the continuous-time equivalent of the discrete-time problem studied by Campbell and Viceira (1999), in which the expected excess return on a risky asset follows...

This paper examines the optimal consumption and portfolio-choice problem of long-horizon investors who have access to a riskless asset with constant return and a risky asset ("stocks") with constant expected return and time-varying precision--the reciprocal of volatility. Markets are incomplete,...

We develop analytic pricing models for options on averages by means of a state-space expansion method. These models augment the class of Asian options to markets where the underlying traded variable follows a mean-reverting process. The approach builds from the digital Asian option on the...
