Document Details : Title: Initial Selection and Cause of Disability for Individual Permanent Health Insurance Author(s): GUTIÉRREZ-DALGADO, M.C. , KORABINSKI, A. Journal: ASTIN Bulletin Volume: 30 Issue: 2 Date: November 2000 Pages: 369-390 DOI: 10.2143/AST.30.2.504641 Abstract : We investigate the influence of initial selection (the impact of underwriting during the early years of a policy's life) on individual Permanent Health Insurance claim inceptions. In Gutiérrez-Delgado (1999) a decreasing trend was found. In this paper we include the effect of cause of disability and fit a generalized linear model in order to gain a greater understanding of the phenomenon. Both effects, policy duration and cause of disability, are found to have a significant effect on the number of claims. We describe their influence using factors that collect the information available through the fitted model. Results from both factors suggest that Ihe grouping of diseases selected for the research helps to explain partially our earlier results. In addition there is some evidence of moral hazard in metatal disorders and musculoskeletal diseases which also contributes to the understanding of the negative trend found. |
