In this paper, we present estimates of the effect of informal care provision on female caregivers' health. We use data from the German Socio-Economic Panel and assess effects up to seven years after care provision. The results suggest that there is a considerable negative short-term effect of informal care provision on mental health which fades out over time. Five years after care provision the effect is still negative but smaller and insignificant. Both short- and medium-term effects on physical health are virtually zero throughout. A simulation analysis is used to assess the sensitivity of the results with respect to potential deviations from the conditional independence assumption in the regression adjusted matching approach.
