Natural Catastrophe Insurance: How Should the Government Intervene?

An updated version of the joint paper with Benoit Le Maux is online on http://papers.ssrn.com/.

The present paper develops a new theoretical framework for analyzing the decision to provide or buy insurance against the risk of natural catastrophes. In contrast with conventional models of insurance, the insurer has a non-zero probability of insolvency that depends on the distribution of the risks, the premium rate, and the amount of capital in the company. Among several results, we show that risk-averse policyholders will accept to pay higher rates for a government-provided insurance with unlimited guarantee. However, depending on the correlation between and within the regional risks, a government program can be more attractive to high-correlation than to low correlation areas, which may lead to inefficiencies if the insurance ratings are not appropriately chosen.

Lecture notes on risk and insurance

I just finished some lectures notes on risk and insurance. The notes, that can be downloaded [pdf], are in French, and will be used at the JES (Journées d’Etudes Statistiques), organised at the CIRM (mentioned here). Previous notes on risk measures [pdf] and copulas [pdf]. Again, all comments are welcome…
