Centro de Documentacion de Fundación MAPFRE - Determinants of corporate diversification : evidence from the property-liability insurance industry

Notas: Sumario: This article analyzes variations in line-of-business diversification status and extent among property-liability insurers. Our results show that the extent of diversification is not driven by risk pooling considerations; insurers operating in more volatile business lines do not diversify more. Diversification can rather be explained by the benefits of internal capital markets and barriers to business growth like market size and concentration. In our analysis, we distinguish between related and unrelated diversification. Using a measure of unrelated line-of-business diversification we find the first support for the diversification prediction of the managerial discretion hypothesis that mutual insurers should be less diversified than stock insurers. While mutual insurers tend to exhibit higher levels of total diversification, they engage in significantly less unrelated diversification than do stock insurers.Registros relacionados: En: The Journal of risk and insurance. - Nueva York : The American Risk and Insurance Association, 1964- = ISSN 0022-4367. - 04/06/2012 Volumen 79 Número 2 - junio 2012 , p. 381-414Materia / lugar / evento: Property Liability Mercado de seguros Métodos analíticos Empresas de seguros Seguro de daños patrimoniales Diversificación de los riesgos Estados Unidos Otros autores: Berry-Stölzle, Thomas R.
