During the last decade unicameral proposals have been put forward in fourteen US states. In this paper we propose a theoretical framework casting some lights on the drawbacks of bicameral state legislatures and on the effects of the proposed constitutional reforms. In a setting where lawmakers...

Gordon Tullock has been one of the most important founders and contributors to Public Choice. Two innovations are typical “Tullock Challenges”. The first relates to method: the measurement of subjective well-being, or happiness. The second relates to digital social networks such as Facebook,...

Since not many valid economic, social or military arguments in favor of the draft can be put forward, the question emerges why societies choose to rely on it.

Although many real bargaining situations involve more than two people, much of the theoretical and experimental research concentrates on the two player situation. We study the simplest possible extension: four people (two two-person groups) of different patience bargain with each other....

We model centralized school matching as a second stage of a simple Tiebout-model and show that the two most discussed mechanisms, the deferred acceptance and the Boston algorithm, both produce inefficient outcomes and that the Boston mechanism is more efficient than deferred acceptance. This...

Neither marriage nor a legally enforceable contract serves any useful purpose if the parties have access to a perfect credit market. In the presence of credit rationing, efficiency and utility equalization are guaranteed only by a legally enforceable contract. Separate-property marriage may...
