The provision of public goods often relies on voluntary contributions and cooperation. While most of the experimental literature focuses on individual contributions, many real-world problems involve the formation of institutions among subgroups (coalitions) of players. International agreements...

We use a laboratory experiment to investigate the behavioral effects of obligations that are not backed by binding deterrent incentives. To implement such expressive law' we introduce different levels of very weakly incentivized, symmetric and asymmetric minimum contribution levels (obligations)...

We analyze the interplay of group identity and inter-group conflict in a contest where each of two conflicting groups can develop either a group or an individualistic identity. Contest structures impact on the adoption of identities which themselves influence behavior in the contest. We show the...

This papers sheds light on the puzzling evidence that even though open source software (OSS) is a public good, it is developed for free by highly qualified, young and motivated individuals, and evolves at a rapid pace. We show that once OSS development is understood as the private provision of a...

In this paper I examine the relationship between Pareto-optimality and group size in linear public goods games or experiments. In particular, I use the standard setting of homogeneous linear public goods experiments and apply a recently developed tool to identify all Pareto-optimal allocations...

We present a legislative bargaining model of the provision of a durable public good over an infinite horizion. In each period, there is a societal endowment which can either be invested in the public good or consumed. We characterize the optimal public policy, defined by the time path of...

We show that the standard trust question routinely used in social capital research is importantly related to cooperation behavior and we provide evidence on the microfoundation of this relation. We run a large-scale public goods experiment over the internet in Denmark using a design that enables...

We develop and apply a new method for estimating the economic benefits of an environmental amenity. The method fits within the household production framework (Becker 1965), and is based upon the notion of estimating the derived demand for a privately traded option to utilize a freely-available...

Socially responsible investment in analyzed in a general equilibrium context. This is important in order to understand the ultimate consequences of SRI on the decisions of economic agents. Building on models by Brock (1982) and Merton (1987), SRI is modelled as the choice to voluntarily give up...

A framework is proposed to subsume public goods and common-pool resources, respectively, as specific cases of positive and negative externalities. A pure public good is a positive externality whose appropriable benefits are too small or too uncertain relative to the high private cost for anyone...
