In the last thirty years, economists and other social scientists have investigated people’s normative views on distributive justice. Here we study people’s normative views in social dilemmas, which underlie many situations of economic and social significance. Using insights from moral...

We consider duopolists innovating and producing a good subject to network externalities, so that the reservation price of a consumer increases with aggregate consumption. The post-innovation network consists of two compatible sub-networks, with increased network valuation of the new product....

We provide a test of the role of social preferences and beliefs in voluntary cooperation and its decline. We elicit individuals’ cooperation preferences in one experiment and use them – as well as subjects’ elicited beliefs – to explain contributions to a public good played repeatedly....

We examine whether government ideology was correlated with the growth in military expenditure in Germany over the period 1951-2011. By using various measures of government ideology, the results do not show any effect. The exception is an ideology measure based on the Comparative Manifesto...

We revisit the classical result that financing a pure public good through taxation of private consumption is inefficient. To this standard setup we add a consumption contest in which consumers can win a prize. We show that an appropriately chosen contest—which we call a ‘tax lottery’—can...

We study fiscal spending by supranational unions, where participation is voluntary and countries bargain over contributions to and the allocation of a central budget. We explore the link between the allocation and nations’ contributions that occurs since bargaining power is endogenous, and...

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...

We examine the role of CSR as a mechanism for private provision of public goods. We argue that corporations are using CSR to signal high product quality and demonstrate that signaling gives rise to an excessive level of contributions that offsets the positive externality, which causes the...

We investigate the link between leadership, beliefs and pro-social behavior. This link is interesting because field evidence suggests that people’s behavior in domains like charitable giving, tax evasion, corporate culture and corruption is influenced by leaders (CEOs, politicians) and beliefs...

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...
