As part of a joint investigation, DIW Berlin and the Institute for Employment Research (IAB) in Nuremberg analyzed how investing in the labor market integration of the refugees who came to Germany in 2015 might impact the overall economy. The institutionsbased their analyses on a simulation model. What are the assumptions underlying this model? We examined data on the 2015 refugees and analyzed this ...
Fundamental changes to security policy in European democracies raise the question of the acceptance of new security measures. This paper aims to explain why new measures are accepted (or not). It combines three core elements that are typically analysed separately in the literature: individual attitudes (especially trust), social context and cost/benefit balancing. Comparing Germany and the UK, the ...

Against this background, the Institute for Employment Research (IAB) in Nuremberg and DIW Berlin conducted a joint investigation (funded by the German Federal Ministry of Labor and Social ...
In a meta-analysis of 126 impact evaluation studies, we find that financial education significantly impacts financial behavior and, to an even larger extent, financial literacy. These results also hold for the subsample of randomized experiments (RCTs). However, intervention impacts are highly heterogeneous: Financial education is less effective for lowincome clients as well as in low and lower-middle ...
Hybrid choice models with latent variables aim to capture unobserved attributes of the individuals and the alternatives, such as attitudes, perceptions, etc., increasing the predictive capability and realism of discrete choice models. Even though, their fundaments are fairly well-established, some technical and theoretical issues have not been extensively analyzed, leading to controversies in the literature. ...
Do increased instruction hours improve the performance of all students? Using PISA scores of students in ninth grade, we analyse the effect of a German education reform that increased weekly instruction hours by two hours (6.5 percent) overalmost five years. In the additional time, students are taught new learning content. On average, the reform improves student performance. However, treatment effects ...
