Reinsurance or Securitization: The Case of Natural Catastrophe Risk


Gibson, Rajna; Habib, Michel; Ziegler, Alexandre (2014). Reinsurance or Securitization: The Case of Natural Catastrophe Risk. Journal of Mathematical Economics, 53:79-100.

Abstract

We investigate the suitability of securitization as an alternative to reinsurance for the purpose of transferring natural catastrophe risk. We characterize the conditions under which one or the other form of risk transfer dominates using a setting in which reinsurers and traders in financial markets produce costly information about catastrophes. Such information is useful to insurers: along with the information produced by insurers themselves, it reduces insurers’ costly capital requirements. However, traderswho seek to benefit from trading in financial markets may produce ‘too much’ information,thereby making risk transfer through securitization prohibitively costly.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
