This paper provides a method for pricing options in the constant elasticity of variance (CEV) model environment using the Lie-algebraic technique when the model parameters are time-dependent. Analytical solutions for the option values incorporating time-dependent model parameters are obtained in...

In this paper, we comment on the paper quot;Pricing Double Barrier Options using Laplace Transformsquot; by Antoon Pelsser. We illustrate that the same solutions of double barrier option values in terms of Fourier sine series can be obtained by using both Laplace transform and the method of...
