On the valuation of constant barrier options under spectrally one-sided exponential Levy models and Carr's approximation for American puts

摘要

This paper provides a general framework for pricing options with a constant barrier under spectrally one-sided exponential Levy model, and uses it to implement of Carr's approximation for the value of the American put under this model. Simple analytic approximations for the exercise boundary and option value are obtained. (C) 2002 Elsevier Science B.V. All rights reserved. [References: 31]
