This paper shows that reciprocity has powerful implications for many economic domains. It is an important determinant in the enforcement of contracts and social norms and enhances the possibilities of collective action greatly. Reciprocity may render the provision of explicit incentive...

In this paper, we develop the concept of a psychological tax contract that goes beyond the traditional deterrence model and explains tax morale as a complicated interaction between taxpayers and the government. Based on crowding theory, the impact of deterrence and rewards on tax morale is...

Field evidence suggests that agents belonging to the same group tend to behave similarly, i.e., behavior exhibits social interaction effects. Testing for such effects raises severe identification problems. We conduct an experiment that avoids these problems. The main design feature is that each...

The traditional economic approach to tax evasion does not appear to be particularly successful in explaining the extent of tax compliance. We argue instead that a psychological tax contract which establishes a fiscal exchange between the state and the citizens shapes tax compliance to a large...

Tax compliance has been studied in economics by analysing the individual decision of a representative person between paying and evading taxes. A neglected aspect of tax compliance is the interaction of taxpayers and tax authorities. The relationship between the two actors can be understood as an...

Why so many people pay their taxes, although fines and audit probability are low, has become a central question in the tax compliance literature. A homo economicus, with a more refined motivation structure, helps us to shed light on this puzzle. This paper provides empirical evidence for the...

Many politicians blame physician dispensing (PD) to increase health care expenditure and to undermine independence of drug prescription and income leading to a suboptimal medication. Therefore, PD is not allowed in most OECD countries. In Switzerland, PD is allowed in some regions depending on...

This paper sheds light on some unexpected consequences of health insurance regulation that may pose a big challenge to insurers’ risk management. Because mandated uniform contributions to health insurance trigger risk selection efforts risk adjustment (RA) schemes become necessary. A good deal...

This study seeks to provide evidence for deciding whether or not a pharmaceutical innovation should be included in the benefit list of social health insurance. A discrete choice experiment (DCE) was conducted in Germany to measure preferences for modern insulin therapy. Of the 1,100 individuals...

When premiums are community-rated, risk adjustment (RA) serves to mitigate competitive insurers’ incentive to select favorable risks. However, unless fully prospective, it also undermines their incentives for efficiency. By capping its volume, one may try to counteract this tendency, exposing...
