We consider perpetual Bermudan options and more general perpetual American options in discrete time. For wide classes of processes and pay-offs, we obtain exact analytical pricing formulae in terms of the factors in the Wiener-Hopf factorization formulae. Under additional conditions on the...

We present a very accurate algorithm for calculating prices of double barrier options, together with a simple set of detailed step-by-step instructions for implementing it in practice. Our algorithm works 5-10 times faster than any other known algorithm. At the same time, it involves no...

We consider the Heston model with the stochastic interest rate of the CIR type and more general models with stochastic volatility and interest rates depending on two CIR - factors. Time derivative and infinitesimal generator of the process for factors that determine the dynamics of the interest...

In the paper, we solve the pricing problem for American options in Markov-modulated Levy models. The early exercise boundaries and prices are calculated using a generalization of Carr's randomization for regime-switching models. The pricing procedure is efficient even if the number of states is...

In the paper, we solve the pricing problem for perpetual American options in Markov-modulated Levy models. The early exercise boundaries and prices are calculated using an iteration procedure. The pricing procedure is efficient even if the number of states is large provided the transition rates...

This paper studies pricing of perpetual American strangles under jump-diffusions. Explicit solutions for option values as functions of the exercise boundaries and the exercise boundaries as functions of the ratio between the boundaries are obtained. Calculation of the ratio of the exercise...
