Since 2009, German nursing homes have been evaluated regularly with quality report cards published online. We argue that most of the information in the report cards does not reliably measure quality of care, but a subset of seven measures does. Using a sample of more than 3,000 nursing homes...

Many countries with national health care providers and health insurances regulate the market for pharmaceuticals to steer drug demand and to control expenses. For example, they introduce reference pricing or tiered co-payments to enhance drug substitution and competition. Since 2006, Germany...

We investigate the welfare impact of parallel imports using a large panel data set containing monthly information on sales, ex-factory prices, and further product characteristics for all 700 anti-diabetic drugs sold in Germany between 2004 and 2010. We estimate a two-stage nested logit model of...

It is a persistent phenomenon in many societies that a large proportion of alcohol consumption takes place in company of other people. While the phenomenon of social or public drinking is well discussed in disciplines as social psychology and anthropology, economists have paid little attention...

Hospital markets are often characterised by price regulation and the existence of different ownership types. Using a Hotelling framework, this paper analyses the effect of heterogeneous objectives of the hospitals on quality differentiation, profits, and overall welfare in a price regulated...

We study the voluntary revelation of private information in a labor-market experiment where workers can reveal their productivity at a cost. While rational revelation improves a worker's payoff, it imposes a negative externality on others and may trigger further revelation. Such unraveling can...

We elicit the willingness to sell personal data (contact information, Facebook details, preferences) in laboratory experiments, using a BDM and take-it-or-leave-it offers. Our experiments are novel in that (i) the experiments are incentivized, (ii) the focus on privacy issues is salient, and...

We analyze the impact of product bundling in experimental markets. One firm has monopoly power in a first market but competes with another firm à la Cournot in a second market. We compare treatments where the multi-product firm (i) always bundles, (ii) never bundles, and (iii) chooses whether...

We explore whether lawful cooperation in buyer groups facilitates collusion in the product market. Buyer groups purchase inputs more economically. In a repeated game, abandoning the buyer group altogether or excluding single firms constitute credible threats. Hence, in theory, buyer groups...
