On the regulator-insurer-interaction in a structural model

In this paper, we provide a new insight to the previous work of Briys and de Varenne [1994], Grosen and Jørgensen [2002] and Chen and Suchanecki [2007]. We show that if the insurance company follows a risk management strategy, it can significantly change the risk exposure of the company, and that it should thus be taken into accountby regulators. We first study how the regulator establishes regulation intervention levels in order to control for instance the default probability of the insurance company. This part of the analysis is based on a constant volatility and there exists a one-to-one relation between the optimal regulation level and the volatility. Given that the insurance company is informed of regulatory rules, we study how results can be significantly different when the insurance company follows a risk management strategy with non-constant volatilities. We thus highlight some limits of prior literature and believe that the value of the company’s risk management should be included in the risk exposure estimation and the market valueof liabilities as well.
