This paper investigates in a principal-agent environment whether and how group membership influences the effectiveness of incentives and when incentives can have hidden costs, i.e., a detrimental effect. We show experimentally that in all interactions control mechanisms can have hidden costs for...

This paper investigates in a principal-agent environment whether and how group membership influences the effectiveness of incentives and when incentives can have “hidden costs”, i.e., a detrimental effect. We show experimentally that in all interactions control mechanisms can have hidden...

During the Great Recession mass demonstrations indicated weakened political support in Europe. We show that growing dissatisfaction often reflects poor economic conditions and unemployment is particularly important. Using individual level data for 16 Western European countries for 1976-2010, we...

In most laboratory experiments concerning prosocial behavior subjects are fully informed how their decision influences the payoff of other players. Outside the laboratory, however, individuals typically have to decide without such detailed knowledge. To assess the effect of information...

We show that growing dissatisfaction reflects poor economic conditions; unemployment is particularly important.

Experimental evidence from simple distribution games supports the view that some individuals have a concern for the effciency of allocations. This motive could be important for the implementation of economic policy proposals. In a typical lab experiment, however, individuals have much more...
