In this paper we show how the Kolm triangle method, which is a standard tool for visualizing allocations in a public good economy, can also be used to provide a diagrammatical exposition of matching mechanisms and their effects on public good supply and welfare. In particular, we describe, on...

We study the effect of leadership in an experimental threshold public "bad" game, where we manipulate both the relative returns of two investments (the more productive of which causes a negative externality) and the extent to which the gains from leadership diffuse to the group. The game...

We consider a theoretical model of a public goods game that incorporates reciprocity, guilt-aversion/surprise-seeking, and the attribution of intentions behind these emotions. In order to test our predictions, we implement the ‘induced beliefs method' and a within-subjects design, using the...

When providing public goods through voluntary contributions, a donor may introduce unilateral matching in order to reduce underprovision of the public good and thus inefficiency. By itself, however, matching benefits the donor but harms the recipient. We apply Cornes and Hartley's aggregative...

The provision of global public goods, such as climate change mitigation and managing fisheries to avoid overharvesting, requires the coordination of national contributions. The contributions are managed by elected governments who, in turn, are subject to public pressure on the matter. In an...

In public good games, voluntary contributions tend to start off high and decline as the game is repeated. If high contributors are matched, however, contributions tend to stay high. We propose a formalization predicting that high contributors will self-select into groups committed to charitable...
