This paper makes use of Hierarchical Bayes Models to model and estimate spatial health effects. We focus on Germany, combining rich individual-level household panel data with administrative county level information to estimate spatial county-level health dependencies. As dependent variable, we...

Excessive alcohol consumption among youth and young adults is a major public health concern. On March 1, 2010 the German federal state of Baden-W rttemberg banned the sale of alcoholic beverages between 10pm and 5am in off-premise outlets (e.g. kiosks, petrol stations, supermarkets). We use rich...

This paper analyses the causal effects of educational mismatch on wages, individual health and job satisfaction. As educational mismatch is subject to unobserved heterogeneity in all of these fields, different identification strategies are applied to derive causal effects. In the wage...

Dual-process theories view decisions as the result of the interaction of two qualitatively different types of processes, automatic/impulsive and controlled/deliberative. This paper considers a model of self-control where each decision can be taken by either an automatic process or a deliberative...

We consider the interaction of intrinsic motivation and concerns for social approval in a laboratory experiment. We elicit a proxy for Fairtrade preferences before the experiment. In the experiment, we elicit willingness to pay for conventional and Fairtrade chocolate. Treatments vary whether...

The classical Heckman (1976, 1979) selection correction estimator (heckit) is misspecified and inconsistent if an interaction of the outcome variable and an explanatory variable matters for selection. To address this specification problem, a full information maximum likelihood estimator and a...

As the number of young children in daycare increases, people start to worry about the effect of early non-parental care. This is of special relevance as investments in the early periods of life are shown to be most important for a child’s long term development. Based on the German national...

This paper investigates the role of early life adversity and home resources in terms of competence formation and school achievement based on data from an epidemiological cohort study following 364 children from birth to adolescence. Results indicate that organic and psychosocial risks present in...

We exploit a policy change in Sweden to estimate the effect of copayments on the demand for children's and adolescents' usage of medical care. To this end, we use population-wide registry data including detailed characteristics of individuals and their medical visits. We examine whether the...

This paper evaluates the impact of reference pricing on prices and co-payments in the (German) market for off-patent pharmaceuticals. We present a theoretical model with price-sensitive and loyal consumers that shows that a decrease in the reference price affects the consumers' co-payments in a...
