    Multifactor spread models for cat bonds in the primary and secondary market
    (Universidad EAFIT, 2014) Gómez Cardona, Laura; Cárcamo Cárcamo, Ulises
    As a result of the reinsurance industry seeking for additional capital capacity in the financial markets, a new class of financial instruments for trading insurance related assets has emerged -- This class is known as Insurance Linked securities (ILS), being Cat bonds the most successful class of ILS so far, reaching an outstanding trading volume of US$7 billion just after 10 years since its public appearance -- Their success derives from its innovative structure, which is attractive to the sponsors as an alternative to reinsurance protection against catastrophic losses, and to the investors as a high yield asset, uncorrelated with other financial securities -- This research seeks to address the need for market players to fully understand the dynamics of Cat Bonds prices in the primary and secondary market, and, to provide a reliable valuation tool for making sound investment decisions -- We propose multifactor spread models in which several variables are included as determinants for the Cat Bond’s spread -- Our results are robust, and have a general applicability in both for the P&C and Life market

    Valle de Aburrá: ¿Quo vadis?
    (Universidad Nacional de Colombia, 2007-08-31) Hermelin Arbaux, Michel; Universidad EAFIT. Departamento de Geología; Michel Hermelin Arbaux (hermelin@eafit.edu.co); Geología Ambiental e Ingeniería Sísmica (GIGAI)
    This paper intents a brief description of the evolution that characterised natural risk prevention in the area surrounding the city of Medellin, Colombia, called the Aburra Valley. Both the lithological and structural composition of the Valle and its topographic and climatic conditions contribute to the abundance of destructive natural phenomena as earthquakes, slope movements, flash floods and, in a lower proportion, to floods. The population increase, which reaches now 3.5 millions inhabitants and the frequent occupation of sites exposed to natural hazards have resulted in numerous disasters. At present two entities called SIMPAD and DAPARD work on risk prevention, on city and department scale respectively. The amount of knowledge about physical environment is considered to be insufficient, together with regulations which should direct land use in accordance to restrictions related to natural hazards. Several seminars on this topic have already been carried out and the organisers of the present one, destined to commemorate the twentieth anniversary of the Villa Tina disaster, should make the decision to meet each two years. Furthermore, the creation of a permanent commission dedicated to study past events, to foster information broadcasting and to seek a better knowledge of the Aburra Valley, should be considered.
