Efficient Fourier Pricing of Multi-Asset Options Using Quasi-Monte Carlo
The authors advocate for using randomized quasi-Monte Carlo (RQMC) quadrature to enhance the scalability of Fourier methods in high dimensions, providing practical error estimates. They propose an efficient domain transformation procedure based on integrand regularity to improve RQMC convergence rates.
