A Two-layer Stochastic Game Approach to Reinsurance Contracting and Competition Bin Zou University of Connecticut Résumé We propose a two-layer stochastic game model to study reinsurance contracting and competition in a market with one insurer and two competing reinsurers. The insurer negotiates with both reinsurers simultaneously for proportional reinsurance contracts that are priced using the […]

The Bernoulli structure of discrete distributions and applications Patrizia Semeraro Politecnico di Torino Résumé We provide a geometrical structure for classes of high dimensional Bernoulli distributions that turns out to be important to address open issues such as dependence or aggregate risk. We focus on the class of Bernoulli variables X = (X1,…,Xd) with given […]
