Seção: Artigos Título: Equilibrium in insurance markets with adverse selection when insurers pay policy dividends / Pierre PicardAutor: Picard, Pierre Notas: Sumario: We show that an equilibrium always exists in the RothschildStiglitz insurance market model with adverse selection and an arbitrary number of risk types, when insurance contracts include policy dividend rules. The MiyazakiWilsonSpence state-contingent allocation is an equilibrium allocation (defined as a set of type-dependent lotteries sustained at a symmetric equilibrium of a market game), and it is the only one when out-of-equilibrium beliefs satisfy a robustness criterion. It is shown that stock insurers and mutuals may coexist, with stock insurers offering insurance coverage at actuarial price and mutuals cross-subsidizing risks.Registros relacionados: En: The Journal of risk and insurance. - Nueva York : The American Risk and Insurance Association, 1964- = ISSN 0022-4367. - 02/12/2019 Volumen 86 Número 4 - diciembre 2019 , p. 887-914Materia / lugar / evento: Gerencia de riesgos Contrato de seguro Modelos actuariales Matemática del seguro Outras classificações: 7 Direitos: In Copyright (InC) Ver detalhe do número
