Experiments involving multiple public goods with contribution thresholds capture many features of charitable giving environments in which donors try to coordinate their contributions across various potential recipients. We present results from a laboratory experiment that introduces endowment...

This paper characterizes efficient tax subsidies for charitable contributions, and considers the properties of potential reforms. Contributions are underprovided in the absence of subsidies, and are misdirected if subsidies fail to account for all of the costs that donors incur. It is costly for...

We experimentally investigate the path dependence of voluntary contributions in a public good game with heterogeneous agents who vary in their ability to increase the public good. More specifically, we analyze whether contribution norms observed in a first phase of the experiment under a...

Using a diagram called a "Kolm triangle" adopted in Kolm (197'7, the important issues of 1) Pareto efficiency and the core, and 2) Lindahl equilibrium and the core in the resource allocation problem involving public goods analyzed by Foley (197'7 and Nikaido (1976) can be illustrated merely...

This paper analyzes the effects of spillovers on the formation of jurisdictions in a local public good economy with free mobility. The number of jurisdictions is fixed and spillovers are parametrized by a matrix [αij where αij ε [0,1]. When spillovers are symmetric and close to 0 or 1 (pure...

Most of the literature on government intervention in models where public goods are provided through voluntary contributions focuses on interventions that change the total level of a public good, which is known to be (almost always) underprovided relative to the "efficient" level. However,...

We prove existence and generic regularity of equilibria in a general equilibrium model of a completely decentralized pure public good economy. Competitive firms using private goods as inputs produce the public good, which is privately provided by households. Previous studies on private provision...

We analyze a general equilibrium model of a completely decentralized pure public good economy. Competitive firms using private goods as inputs produce the public good, which is privately provided by households. Previous studies on private provision of public goods typically use one private good,...
