In this paper insurance claims are priced using an indifference pricing principle. We first revisit the traditional economic framework and then extend it to include the presence of a complete financial market. In this context we derive lower bounds for claims' prices, and these bounds correspond to the market prices of some explicitly known financial payoffs. In particular we show that the discounted expected value is no longer valid as a classical lower bound for insurance prices in general, and has to be corrected by a covariance term which reflects the interaction between the insurance claim and the financial market. The paper is illustrated by examples with equity-linked insurance contracts subject to financial and mortality risk.
