In our project, we focus on the labor force participation of older workers with adverse healthconditions (i.e., chronic conditions, injuries, or illnesses, both in physical and mental terms). Evidence shows that a non-negligible share of workers experiences adverse health conditions at the end of their careers. While many older workers exit the labor force due these adverse healthconditions, others remain in the labor force. This raises the question which factors affect the labor force participation of older workers with adverse health conditions. On the one hand, some older workers with adverse health conditions may be constraint to continue working involuntary, for instance to guarantee their level of living. Onthe other hand, some of them may continue to work voluntarily, for instance because they are able to adjust their activity level.
