Das Working Paper von Lukas Reichel, Hato Schmeiser und Florian Schreiber mit dem Titel «On the Optimal Management of Counterparty Risk in Reinsurance Contracts» ist im Journal of Economic Behavior and Organization zur Publikation angenommen worden. Die Ergebnisse der Arbeit können wie folgt zusammengefasst werden:
We use a normative analysis and consider the optimal reinsurance coverage structure in the presence of counterparty risk. From the perspective of a risk-averse primary insurer, we derive a cost criterion that indicates the optimality of under-, over- and full hedging of the reinsurers’ counterparty risk and show how the hedging preference can define a vertical layering of the reinsurance coverage. We also determine the optimal diversification strategies between two reinsurers that differ in their counterparty risk. Our results provide evidence that the coverage is allocated either to a single reinsurer or to both in the form of a vertical (quota share) and horizontal (excess-of-loss) allocation. Finally, we demonstrate how to optimally combine hedging and diversification.

About the Journal:
The Journal of Economic Behavior and Organization is devoted to theoretical and empirical research concerning economic decision, organization and behavior and to economic change in all its aspects. Its specific purposes are to foster an improved understanding of how human cognitive, computational and informational characteristics influence the working of economic organizations and market economies and how an economy’s structural features lead to various types of micro and macro behavior, to changing patterns of development and to institutional evolution. Research with these purposes that explore the interrelations of economics with other disciplines such as biology, psychology, law, anthropology, sociology, finance, marketing, political science, and mathematics is particularly welcome. The journal is eclectic as to research method; systematic observation and careful description, simulation modeling and mathematical analysis are all within its purview. Empirical work, including controlled laboratory experimentation that probes close to the core of the issues in theoretical dispute is encouraged.
