Sensitivity analysis has become an important tool to test the robustness of estimated economic models. In this paper we propose the use of simulation-based sensitivity analysis to identify the fundamental structure of the economy. To show the possibilities of this technique, we provide empirical evidence on the path of structural change occurring in the Chicago economy by running simulation in ...

BACKGROUND Work life expectancy (WLE) expresses the expected time a person will remain in the labor market until he or she retires. This paper compares a life table approach to estimating WLE to an approach based on multi-state proportional hazards models. The two methods are used to estimate WLE in Danish members and non-members of an early retirement pensioning (ERP) scheme according to level...
