Option valuation models are usually based on frictionless markets. This paper extends and complements the literature by developing a model of option pricing in which the derivative and/or the underlying asset have an oligopolistic market structure, which produces an expected return on these...

This paper investigates pairwise efficient forward trading followed by spot market competition. The model finds that forward trading rules out a “bilateral oligopoly” spot market where at least one net seller under-supplies and least one net buyer under-procures. If not, both firms, by...

With the rapid development of option markets throughout the world, option pricing has become an important field in financial engineering. Among a variety of option pricing models, volatility of underlying asset is associated with risk and uncertainty, and hence is treated as one of the key...

As is well known, the classic Black-Scholes option pricing model assumes that returns follow Brownian motion. It is widely recognized that return processes differ from this benchmark in at least three important ways. First, asset prices jump, leading to non-normal return innovations. Second,...

We develop a simple robust test for the presence of continuous and discontinuous (jump) components in the price of an asset underlying an option. Our test examines the prices of at-the-money and out-of-the-money options as the option maturity approaches zero. We show that these prices converge...

We consider the hedging of derivative securities when the price movement of the underlying asset can exhibit random jumps. Under a one factor Markovian setting, we derive a spanning relation between a long term option and a continuum of short term options. We then apply this spanning relation to...

The binomial model has been used to price a wide variety of equity and interest rate options for more than two decades. Originally developed by Cox, Ross, and Rubinstein to clarify the basic pricing principle of its continuous-time counterpart with reduced mathematical requirements, the approach...

In the past decades several versions of the binomial model for option pricing, originally introduced by Cox, Ross, and Rubinstein, have been discussed in the finance literature. Some of these approaches model an arbitrage-free market in the discrete setup whereas others attain this property only...

Three years after the seminal work of Black and Scholes on the pricing of European options, Scholes presented a paper in which the impact of taxation on the value of an option is analyzed. We restart this discussion in a simple binomial setting emphasizing the economic principles of replicating...
