For pricing any contingent claim that depends on financial risks and mortality an assumption has to be made about the dependency structure between the two sources of risk. It is often assumed that those two sources of risk are independent – a very strong assumption which might not always be satisfied. In this paper we consider annuity prices and the fair value of pension buyout contracts using a model in which interest rates, asset prices and mortality rates experience common shocks to investigate the impact of the (violation of the) independence assumption on pricing.
