Empirical evidence is provided for the importance of non-reciprocal pro-social behavior of individuals in an anonymous, n-person pure public good setting. A unique panel data set of 136,000 observations is matched with an extensive survey. Even under anonymous conditions, a large number of...

Attempts to curb illegal activity through regulation gets complicated when agents can adapt to circumvent enforcement. Economic theory suggests that conducting audits on a predictable schedule, and (counter-intuitively) at high frequency, can undermine the effectiveness of audits. We conduct a...

This paper studies public goods provision in an experiment in which contributors repeatedly interact with rent-extracting administrators. Our main result is that the presence of an administrator reduces contributions but only because rent extraction lowers the MPCR. Analysing the dynamic...

In this paper, we show that a concept of aggregation can hold in network games. Breaking up large networks into smaller pieces, which can be replaced by representative players, leads to a coarse-grained description of strategic interactions. This method of summarizing complex strategic...

Institutions for co-financing agreements often exist to encourage public good investment. Can such frameworks deliver maximal investment when agents are motivated by reciprocity? We demonstrate that indeed they can, but not in the way one might expect. If maximal investment is impossible in the...

In a family context with endogenous timing, multiple public goods and alternative parental instruments, we show that the optimal timing for the sequential-action game played by rotten kids and a parent depends crucially on whether the kids are homogeneous or heterogeneous. For homogeneous kids,...

This paper extends theory and experimentation in the context of two parties in a group who contribute to a public good with a provision point. This study analyzes the voluntary contributions game in which a public good is provided if and only if the sum of contributions meets or exceeds a...

In many empirically relevant situations agents in different groups are affected by the provision of a public characteristic in divergent ways: While for one group it represents a public good, it is a public bad for another group. Applying Cornes'and Hartley's (2007) Aggregative Game Approach, we...

This paper analyses the private provision of public goods where agents interact within a fixed network structure and may benefit only from their direct neighbours' provisions. We survey the literature and then generalise the public goods in networks model of Bramoullé and Kranton (2007) to...

This paper considers endogenous coalition formations and endogenous technology choices in a model of private provision of global public goods. We show that the possibility of future interstate (partial) coordination may hinder the current adoption of better technology by a country outside the...
