Abstract:
|
Writers of insurance guarantees have increasingly sought pricing improvement through model complexity. However, complex options often have no closed-form pricing solution and guarantees must be priced through stochastic simulation of the underlying asset. Regime-switching models are an intuitive way to incorporate stochastic volatility into the simulated asset price and have been shown to accurately model single asset streams (e.g., stock index data). Many guarantees, however, are based on multiple assets. Ignoring between-asset correlation can expose the writer to significant pricing risk. We develop a multivariate regime-switching model and compare different prior specifications for the between-asset correlations.
