• Existence and uniqueness of equilibrium in a reinsurance syndicate 

      Aase, Knut K. (Discussion paper, Working paper, 2008-07)
      In this paper we consider a reinsurance syndicate, assuming that Pareto optimal allocations exist. Under a continuity assumption on preferences, we show that a competitive equilibrium exists and is unique. Our conditions ...
    • Financial economics 

      Aase, Knut K. (Discussion paper, Working paper, 2003-01)
      We consider a one period (two time points-) model of efficient risk sharing, when the risk of possible sharing rules are constrained to be linear. This can be interpreted as a model of a market for common stocks. Here we ...
    • Optimal risk sharing 

      Aase, Knut K. (Discussion paper, Working paper, 2003-01)
      Optimal risk sharing is considered from the perspective of the risk sharing model introduced by Karl Borch in the late 50ies. First we introduce, in a modern setting, the main concepts from this theory. These we apply ...
    • Optimal Risk-Sharing and Deductables in Insurance 

      Aase, Knut K. (Discussion paper, Working paper, 2006)
      Risk-sharing in insurance is analyzed, with a view towards explaining the prevalence of deductibles. First we introduce, in a modern setting, the main concepts of the theory of risk-sharing in a group of agents. This theory ...
    • Perspectives of risk sharing 

      Aase, Knut K. (Discussion paper, Working paper, 2000-05)
      In this paper we present an overview of the standard risk sharing model of insurance. We discuss and characterize a competitive equilibrium, Pareto optimality, and representative agent pricing, including its implications ...
    • Pooling in insurance 

      Aase, Knut K. (Discussion paper, Working paper, 2003-01)
      Risk sharing resulting in pooling of risk is considered. First pooling is discussed from the perspective of life and pension insurance. Second we take the perspective of Pareto optimal risk sharing, originating from a model ...
