In this study, the causal nexus between child mortality rate, fertility rate, GDP, household final consumption expenditure, and food production index in Ghana was investigated spanning from 1971 to 2013 using the Autoregressive and Distributed Lag (ARDL) method. The study tested for unit root,...

This paper examines the causal effect of the experience of a hospital with treating hip fractures (volume) on treatment outcome for patients. A full sample of administrative data from Germany for the year 2007 is used. We apply an instrumental variable approach to eliminate endogeneity concerns...

This paper examines the causal effect of volume on outcome on the example of patients with a hip fracture. We use an instrumental variable approach and consider both the practice-makes-perfect and selective-referral hypothesis as well as unobserved patient heterogeneity. Our results indicate...

One cornerstone of current attempts to reform the German public health care system by introducing private insurance schemes is the assumption that economic incentives play an important role in individual decision-making about using medical help. This hypothesis is examined for the case of demand...

Learning-by-doing is a fundamental concept in economics but a challenging one to document in high-skilled settings due to non-random assignment of workers to tasks and lacking performance measures. Our paper overcomes these challenges in the context of heart attack treatments in Sweden, where we...

We investigate the impact of obstetrician supervision, as opposed to midwife supervision, on the short-term health of low-risk newborns. We exploit a unique policy rule in the Netherlands that creates a large discontinuity in the probability of a low-risk birth being attended by an obstetrician...

This paper examines the efficiency of the German hospital sector over time and the relative efficiency of public, welfare (both nonprofit) and private (for-profit) hospital sectors using data from the Federal Statistics Office of German hospitals. Efficiency scores were computed using Data...
