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).
