We propose a parsimonious general equilibrium extension of the Black-Scholes economy that helps clarify how options' prices, expected returns, risk exposure, and optimal exercise policies respond to variations in the risk exposure of the underlying asset. The model allows one to separate the...

We examine the impact on an R&D valuation and its investment timing of abrupt events, options facing paradise (blockbusters) and purgatory (catastrophes). We show that the presence of a special case of Lévy jumps can model positive and negative effects in the investment opportunity even when...

Governments and corporations frequently auction assets with embedded real options using both cash and contingent bids. I characterize equilibrium bidding and option exercise strategies, and find that the moral hazard associated with uncontractible investment timing inefficiently and...

Compound options are options for which the underlying is another option. In other words, a compound option is an option written on an option. In this paper, we present two new approaches to compound option pricing. The first approach relies on Malliavin calculus methods and the Clark-Ocone...

Avian flu has been the focus of significant attention since 2004, when there were reports of human infections in Asia from the avian flu H5N1 strain. To prevent the catastrophic mortality of mankind, several governments are stockpiling antivirals and pharmaceutical firms are increasing their...

In this paper, we derive optimal hedging strategies for options in electricity futures markets. Optimality is measured in terms of minimal variance and the associated minimal variance hedging portfolios are obtained by a stochastic maximum principle. Our explicit results are particularly useful...

This paper investigates whether the overpricing of out-of-the money single stock calls can be explained by Tversky and Kahneman's (1992) cumulative prospect theory (CPT). We hypothesize that these options are expensive because investors overweight small probability events and overpay for...

In this paper we consider the problem of pricing and hedging European derivatives written on two underlying assets, when individual marginal distributions are known. Our aim is twofold. First, we conduct a parallel analysis between implied volatility and implied correlation for spread options in...

In this paper, I have used simple arbitrage argument to derive a dozen of model-free option price properties. In addition to deriving the Greeks under the model-free framework, the results show that first, in contrast to the traditional view, a European call (put) option for a...
