Quantifying factors giving rise to temporal variation in forest fires is important for advancing scientific understanding and improving fire prevention. We demonstrate that eighty percent of the large year-to-year variation in forest area burned in California can be accounted for by variation in...

This paper examines the market for catastrophe event risk i.e., financial claims that are linked to losses associated with natural hazards, such as hurricanes and earthquakes. Risk management theory suggests protection by insurers and other corporations against the largest cat events is most...

Financial instruments whose payoffs are linked to exogenous events, such as the occurrence of a natural catastrophe or an unusual weather pattern depend crucially on actuarial models for determining event (e.g., default) probabilities. In many instances, investors appear to receive premiums far...

This paper discusses the recent changes in the market for catastrophe risk. These risks have traditionally been distributed through the insurance and reinsurance systems. However, because insurance companies tend to share relatively small amounts of their cat exposures and because insurance...

This paper examines the market for catastrophe event risk -- i.e., financial claims that are linked to losses associated with natural hazards, such as hurricanes and earthquakes. This market is in transition as new approaches for transferring risk are being explored. The paper studies several...

We explore two theories that have been advanced to explain the patterns in U.S. catastrophe reinsurance pricing. The first is that price variation is tied to demand shocks, driven in effect by changes in actuarially expected losses. The second holds that the supply of capital to the reinsurance...

This paper argues that the financial exposure of households and firms to natural catastrophe disasters is borne primarily by insurance companies. Surprisingly, insurers use reinsurance to cover only a small fraction of these exposures, yet many insurers do not have enough capital and surplus to...

We model the equilibrium price and quantity of risk transfer between firms and financial intermediaries. Value-maximizing firms have downward sloping demands to cede risk, while intermediaries, who assume risk, provide less-than-fully-elastic supply. We show that equilibrium required returns...

This paper examines the optimal design of insurance and reinsurance policies. We first consider reinsurance for catastrophes: risks which are large for any one insurer but not for the reinsurance market as a whole. Reinsurance for catastrophes is complicated by adverse selection. Optimal...

It is well established that the social and economic environment of medical care distinguishes its provision from that of other goods and services. While scholars have studied the influences of this idiosyncratic environment, there is relatively little empirical knowledge about how it affects...
