This paper estimates the effect of informal care provision on female caregiver’s health. We use data from the German Socio-economic Panel and assess effects up to seven years after care provision. A simulation-based sensitivity analysis scrutinizes the sensitivity of the results with...

An increasing number of developing countries engage in contract manufacturing for a decreasing number of global buyers. This constellation characterises many labour intensive export sectors. The positioning of developing country enterprises in such buyer-driven chains is central to research...

Non-response weighting is a commonly used method to adjust for bias due to unit non-response in surveys. Theory and simulations show that, to reduce bias effectively without increasing variance, a covariate that is used for non-response weighting adjustment needs to be highly associated with...
