Interconnectedness among insurers and reinsurers at a global level is not well understood and may pose a significant risk to the sector, with implications for the macroeconomy. Models of the complex interactions among reinsurers and with other participants in the financial system and the real...

This paper demonstrates that the link between heterogeneity in longevity and lifetime income across countries is mostly high and often increasing; that it translates into an implicit tax/subsidy, with rates reaching 20 percent and higher in some countries; that such rates risk perverting...

Deductibles in health insurance are often regarded as a means to contain health care costs when individuals exhibit moral hazard. However, in the absence of moral hazard, voluntarily chosen deductibles may instead lead to self-selection into different insurance contracts. We use a set of new...

The reliability of general self-rated health status is examined using the reform of the public health insurance system of Germany in 2004 as a source of exogenous variation. Among others, the reform introduced a co-payment for ambulatory doctor visits and increased the co-payments for...

In tandem with the growth of microloans and microsavings, insurance policies geared towards low-income households have also become increasingly widespread over the past decade in developing and emerging countries. There is hope that microinsurance will allow large segments of the population who...

The main objective of this paper is to survey and evaluate the performance of the most popular univariate VaR methodologies, paying particular attention to their underlying assumptions and to their logical flaws. In the process, we show that the Historical Simulation method and its variants can...

We analyze optimal hedging contracts and show that although hedging aims at sharing risk, it can lead to more risk-taking. News implying that a hedge is likely to be loss-making undermines the risk-prevention incentives of the protection seller. This incentive problem limits the capacity to...

We study the optimal design of clearing systems. We analyze how counterparty risk should be allocated, whether traders should be fully insured against that risk, and how moral hazard affects the optimal allocation of risk. The main advantage of centralized clearing, as opposed to no or...

In 2015, 70% of newly-issued leveraged loans had weaker enforcement features, called covenant-light or "cov-lite;" this is nearly a three-time increase in cov-lite issuance compared to a previous peak in 2007. We evaluate whether this development can be attributed to market overheating, increased...
