Document Details : Title: Measuring Process Risk in Income Protection Insurance Author(s): HABERMAN, S. , BUTT, Z. , RICKAYZEN, B. Journal: ASTIN Bulletin Volume: 34 Issue: 1 Date: May 2004 Pages: 199-227 DOI: 10.2143/AST.34.1.504962 Abstract : The main objective of this paper is to measure the process error for a portfolio of independent disability insurance policies in a multiple state modelling context. We consider the calculation of premiums for a portfolio of income protection insurance policies in a stochastic environment represented both by random transitions in the underlying multiple state model and random external economic factors in the form of stochastic investment returns and inflation. We also investigate the sensitivity of the process error to the level of volatility incorporated in a given model using suitably defined risk measures. We then draw conclusions and identify possible avenues for future research. |
