Stochastic Vortexes and Permanent Disability

Research output: Contribution to journalArticle

Abstract

Stochastic vortexes offer useful models in great variety of situations in which populations are open with entrances and departures. The population covered by Social Security is such a population. The cases where workers receive a disability pension are the basis of this study. Using a Spanish data set, we developed a model to estimate the long run distribution for the number of permanent invalid in the various ages, which is used to calculate a lower bound for Social Security responsibility, per capita.
