We conducted a laboratory experiment to study the price setting behavior in two-sided markets. We seek to answer two specific research questions: Do participants charge the equilibrium prices that can be derived from a theoretical model? How is the price setting affected by the characteristics...

Price transparency in the sense of ‘more information for customers’ is known to increase efficiency. However, the introduction of price transparency platforms does not only providemore information for customers but also for rival firms—who may (mis)use the legal information channel to...

We explore how competition between physicians affects medical service provision. Previous research has shown that, in the absence of competition, physicians deviate from patient-optimal treatment under payment systems like capitation and fee-for-service. While competition might potentially...

We study private communication in social networks prior to a majority vote on two alternative policies. Some (or all) agents receive a private imperfect signal about which policy is correct. They can, but need not, recommend a policy to their neighbors in the social network prior to the vote. We...

We investigate the effects of voting power in a committee in which one member (the chairman) holds, on top of a regular vote, also the power to break ties. The chairman is able to induce her preferred outcome much more often than predicted by theory, but only partially because of exercising...

I investigate if, how, and why the effect of a contribution rule in a public goods game depends on how it is implemented: endogenously chosen or externally imposed. The rule prescribes full contributions to the public good backed by a nondeterrent sanction for those who do not comply. My...

We consider a model of redistributive politics in which politicians have the possibility to raise some debt and to implement a pie-increasing reform, i.e. a reform creating a net increase in the total taxable endowment. The reform benefits occur in the future and the reform costs have to be paid...

In using their citizen candidate framework, Besley and Coate (2001) fi nd that if citizen candidates with sufficiently extreme preferences are available, lobbying has no in fluence on equilibrium policy. I show that this result does not hold in a model with ideological parties instead of citizen...

This paper investigates the effects of different prize structures on the effort choices of participants in two-stage elimination contests. A format with a single prize is shown to maximize total effort over both stages, but induces low effort in stage 1 and high effort in stage 2. By contrast, a...
