Summary Model: a life insurance company offering contracts

with a cliquet-style interest rate guarantee

Extension to Kling, Richter, and Ruβ (2007), by incorporating 3 correlated AR(1) GARCH(1,1) processes

Monte Carlo Simulations for different asset allocation strategies

Findings Benefits from investing in hedge funds:

Higher expected returns in the case of event-driven hedge funds
