We provide a solution to the free-rider problem in the provision of a public good. To this end we define a biased indirect contribution game which provides the efficient amount of the public good in non-cooperative Nash equilibrium. No confiscatory taxes or other means of coercion are used. We...

Immigration is a major challenge and opportunity for rich Western countries. Integration of immigrants is a two-way process, the success of which depends both on immigrants and on natives. We provide new evidence on the determinants of individual attitudes towards immigration, using data from...

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...

We analyze the revenue-enhancing potential of favoring specific contestants in complete information all-pay auctions and lottery contests with several heterogeneous contestants. Two instruments of favoritism are considered: Head starts that are added to the bids of specific contestants and...

We develop and test a theory of voting and turnout decisions that integrates self-interest, social preferences, and expressive motives. Our model implies that if pocketbook benefits are relevant, voters either perceive their impact on the outcome to be non-negligible, or expressive motivations...
