| Abstract Text | The wealth dynamics of insurance companies strongly depends on the success of their investment strategies, but also on liquidity shocks which occur during unfavorable years, when indemnities to be paid to the clients exceed collected premia. An investment strategy that does not take liquidity shocks into account, exposes insurance companies to the risk of bankruptcy. This paper analyzes the behavior of insurance companies in an evolutionary framework. We show that an insurance company that merely satisfies regulatory constraints will eventually vanish from the market. We give a more restrictive no-bankruptcy condition for the investment strategies and we characterize trading strategies that are evolutionary stable, i.e., able to drive out any mutation. We study the existence of such strategies and the conditions under which financial and insurance markets are stable. |
