The economics 'credibility revolution' has promoted the identification of causal relationships using difference-in-differences (DID), instrumental variables (IV), randomized control trials (RCT) and regression discontinuity design (RDD) methods. The extent to which a reader should trust claims...

Understanding the mechanisms through which treatment effects come about is crucial for designing effective interventions. The identification of such causal mechanisms is challenging and typically requires strong assumptions. This paper discusses identification and estimation of natural direct...

Let Y be an outcome of interest, X a vector of treatment measures, and W a vector of pre-treatment control variables. Here X may include (combinations of) continuous, discrete, and/or non-mutually exclusive "treatments". Consider the linear regression of Y onto X in a subpopulation homogenous in...

Longitudinal studies on associations between changes in living environment and health are few and focus on movers. Next to causal effects, differences in health between living environments can, however, result due to residential mobility. The present study explored changes in living environment...

Big Data refers to data sets of much larger size, higher frequency, and often more personalized information. Examples include data collected by smart sensors in homes or aggregation of tweets on Twitter. In small data sets, traditional econometric methods tend to outperform more complex...

Eine wichtige zwischen den Bundesländern variierende schulrechtliche Regelung ist die Verbindlichkeit der Schullaufbahnempfehlung beim Übergang von der Grundschule auf die weiterführenden Schulen. Während sie in einigen Bundesländern bindend ist, wird in anderen Bundesländern den Eltern...
