In this paper we propose a jump-diffusion Libor model with jumps in a high-dimensional space (m) and test a stable non-parametric calibration algorithm that takes into account a given local covariance structure. The algorithm returns smooth and simply structured Levy densities, and penalizes...

<title>Abstract</title> In this paper we consider the valuation of Bermudan callable derivatives with multiple exercise rights. We present in this context a new primal--dual <italic>linear</italic> Monte Carlo algorithm that allows for efficient simulation of the lower and upper price bounds without using nested simulations...

Kolodko and Schoenmakers (2006) and Bender and Schoenmakers (2006) introduced a policy iteration that allows the achievement of a tight lower approximations of the price for early exercise options via a nested Monte Carlo simulation in a Markovian setting. In this paper we enhance the algorithm...

Numerical algorithms for the efficient pricing of multidimensional discrete-time American and Bermudan options are constructed using regression methods and a new approach for computing upper bounds of the options' price. Using the sample space with payoffs at optimal stopping times, we propose...
