Abstract: This paper concerns the problem of valuing Bermudan swaptions in
a Libor market model. In particular we consider various efficiency improvement
techniques for a Monte Carlo based valuation method. We
suggest a simplification of the Andersen (2000) exercise strategy and find
it to be much more efficient. Furthermore, we test a range of control
variates for Bermudan swaptions using a control variate technique for
American options proposed in Rasmussen (2002). Application of these
efficiency improvements in the Primal-Dual simulation algorithm of Andersen
& Broadie (2001) improves both upper and lower bounds for the
price estimates. For the Primal-Dual simulation algorithm we examine
the variance-bias trade-off between the numbers of outer an inner paths.
Finally, we demonstrate that the presence of stochastic volatility increases
the expected losses from using the simple strategy in Andersen (2000).
