This article focuses on business risk management in the insurance industry. A methodology for estimating the profit loss caused by each customer in the portfolio due to policy cancellation is proposed. Using data from a European insurance company, customer behaviour over time is analyzed in order to estimate the probability of policy cancelation and the resulting potential profit loss due to cancellation. Customers may have up to two different lines of business contracts: motor insurance and other diverse insurance (such as, home contents, life or accident insurance). Implications for understanding customer cancellation behaviour as the core of business risk management are outlined.
We generalize the test proposed by Kojadinovic, Segers and Yan which is used for testing whether the data belongs to the family of extreme value copulas. We prove that the generalized test can be applied whatever the alternative hypothesis. We also study the effect of using different extreme value copulas in the context of risk estimation. To measure the risk we use a quantile. Our results have been motivated by a bivariate sample of losses from a real database of auto insurance claims.MSC: MSC62-07 MSC62F05.
Para Oviedo, América fue la Tierra Prometida, el Jardín edénico, pero también el Imperio del Demonio. Su Historia General y Natural de las Indias, tan omniabarcadora, minuciosa, y tan moral, representó el choque de estos dos escenarios; la pugna librada en el Nuevo Mundo entre las fuerzas del Bien y el Mal, ambas protagónicas en su intransigente crónica. Frente a una exultante naturaleza -símbolo de inocencia, abundancia y divinidad-, hambre, plagas, enfermedades, adversidades naturales, todos los pecados capitales e innumerables fuerzas diabólicas danzaron por su Historia, cual desfile apocalíptico, acongojando al lector. A partir del Libro XXIX, sobre las crueldades de Pedrarias y sus esbirros, y denominado «infernal»; y del desalentador Libro L de «Infortunios y naufragios», este artículo pone su foco en los padecimientos de conquistados y conquistadores, en el modo en que Oviedo enjuició a estos actantes y en cómo narró sus trágicos avatares en tierras indianas.
