We develop a model that combines competitive exchange of private commodities across endogenously formed groups with public good provision and global collective decisions. There is a tension between local and global collective decisions. In particular, we show that group formation and collective...

Since the middle of the 1980s many European countries have reduced the strictness of their employment protection mainly by relaxing it for temporary jobs. These countries are Belgium, Denmark, Germany, Greece, Italy, the Netherlands, Portugal, Spain and Sweden. The article explores the...

We study political competition in an environment in which voters have private information about their preferences. Our framework covers models of income taxation, public-goods provision or publicly provided private goods. Politicians are vote-share-maximizers. They can propose any policy that is...

We study the role of self-interest and social preferences in referenda. Our analysis is based on collective purchasing decisions of university students on deep-discount flat rate tickets for public transportation and culture. Individual usage data allows quantifying monetary benefits associated...

Institutions are an important means for fostering prosocial behaviors, but in many contexts their scope is limited and they govern only a subset of all socially desirable acts. We use a laboratory experiment to study how the presence and nature of an institution that enforces prosocial behavior...

This paper overviews theoretical and empirical contributions that study political borders from an economic perspective. It reviews theories of the number and size of nations focused on the trade-off between economies of scale in public-good provision and heterogeneity of preferences over public...

Do democratically chosen rules lead to more cooperation and, hence, higher efficiency, than imposed rules? To discuss when such a "dividend of democracy" obtains, we review experimental studies in which material incentives remain stacked against cooperation (i.e., free-riding incentives prevail)...

This paper investigates the relationship between electoral incentives, institutions and corruption. We assume that voters use a yardstick criterion. The incumbent provides a public good and extracts rent, which are financed by imposing a distortionary tax. We demonstrate the possibility that...

This paper develops an expanded framework for social planning in which the existence of coercion is explicitly acknowledged. Key issues concern the precise definition of coercion for individuals and in the aggregate, its difference from redistribution, and its incorporation into normative...
