Risk management is now present in many economic sectors. We investigate the role of risk management and financial intermediation in creating value for financial institutions by analyzing U.S. property-liability insurers. Our main goal is to test how risk management and financial intermediation activities create value for insurers by enhancing economic(More)
The objective of this paper is to investigate the use of tick-by-tick data for market risk measurement. We propose an Intraday Value at Risk (IVaR) at different horizons based on irregularly time-spaced high-frequency data by using an intraday Monte Carlo simulation. An UHF-GARCH model extending the framework of Engle (2000) is used to specify the joint(More)
The identi…cation of information problems in di¤erent markets is a challenging issue in the economic literature. This paper performs tests of asymmetric information in the French automobile insurance market for the 1995-1997 period. This market is characterized by the presence of a regulated experience-rating scheme (bonus-malus). Contract choices are(More)
The rapid growth of off-balance-sheet activities raises a number of interesting issues regarding the relationship between banks capital, securitization and risk. This paper is the first attempt that empirically investigates this relationship. The evidence for Canada over the 1988–1998 period indicates that a) securitization has negative effects on both Tier(More)
The new NYSE rules for corporate governance require the audit committee to discuss and review the firm's risk assessment and hedging strategies. They also put additional requirements for the composition and the financial knowledge of the directors sitting on the board and on the audit committee. In this paper, we investigate whether these new rules as well(More)
Cet article établit une liaison entre la théorie de l'audit optimal et la méthodologie du scoring dans un contexte d'asymétrie d'information. L'application retenue concerne la fraude à l'assurance, mais la même approche peut être appliquée à d'autres activités qui utilisent le scoring. Nous montrons que la stratégie et l'audit optimal consistent à(More)
Studies about credit spread switching regimes typically make assumptions about the number of regimes for in-sample regime detection. This is because exploratory regime detection techniques are lacking in the literature. We employ a real time sequential technique to detect possible breakpoints in the mean and the variance of credit spreads. Our evidence(More)
We explore how the demand for a risky asset can be separated into an investment effect and a hedging effect by all risk-averse investors. This question has been shown to be complex when considered outside of the mean-variance framework. We restrict dependence among returns on the risky assets to regression dependence and find that the demand for one risky(More)
Les politiques de sécurité routière utilisent souvent des mécanismes incitatifs basés sur les infractions pour améliorer le comportement des conducteurs. Ces mécanismes sont par exemple des amendes, des primes d'assurance ou des permis à points. Nous analysons l'efficacité incitative de ces mécanismes. Nous obtenons leurs propriétés théoriques par rapport(More)
