Suppose are independent subexponential random variables with partial sums. We show that if the pairwise sums of the ’s are subexponential, then is subexponential and . The result is applied to give conditions under which as , where are constants such that is a.s. convergent. Asymptotic tail...

Traditionally, insurance risks are borne in reinsurance markets. In 1990s, however, after the sequence of huge natural disasters and huge insurance payments, the reinsurance markets reduced its capability to bear risks, especially those related to catastrophic natural disasters....

The paper studies insurance with moral hazard in a system of contingent-claims markets. Insurance buyers are modelled as Cournot monopolists or oligopolists. The other agents condition their expectations on market prices, as in models of rational-expectations equilibrium with asymmetric...

It is widely recognized that ?market failure? prevents efficient risk sharing in natural disaster insurance. As a consequence, many countries adopted institutional frameworks presenting public sector participation, often praised as public-private partnerships. We define risk selection as a...

Risk transfer between primary insurance and reinsurance companies today takes place against a backdrop of major changes in international insurance and financial markets. One of these changes is the trend for the two markets to converge. This trend manifests itself in a growing number of product...

We study the consequences and optimal design of bank deposit insurance in a general equilibrium model. The model involves two production sectors. One sector is financed by issuing bonds to risk-averse households. Firms in the other sector are monitored and financed by banks. Households fund...

The use of catastrophe bonds (cat bonds) implies the problem of the so called basis risk, resulting from the fact that, in contrast to traditional reinsurance, this kind of coverage cannot be a perfect hedge for the primary’s insured portfolio. On the other hand cat bonds offer some very...
