We experiment a new mechanism for the provision of a discrete public good: in a fixed period individuals can contribute several times; at any moment they can see the total amount collected; at the end of the period, the public good is provided if the amount covers the cost. We find that the...

The Conditional Contribution Mechanism for public good provision gives all agents the possibility to condition their contribution on the total level of contribution provided by all agents. In this experimental study the mechanism's performance is compared to the performance of the Voluntary...

Many mechanisms have been designed to solve the free-rider problem in public good environments. The designers of those mechanisms focused on good static equilibrium properties. In this paper, I propose a new mechanism for the provision of public goods that has good dynamic properties instead....

We present a new and simple mechanism for repeated public good environments. In the Conditional Contribution Mechanism (CCM), agents send two message of the form, "I am willing to contribute x units to the public good if in total y units are contributed." This mechanism offers agents risk-free...

We study the provision of an excludable public good to discuss whether the imposition of participation constraints is desirable. It is shown that this question may equivalently be cast as follows: should a firm that produces a public good receive tax revenues, or face a self-financing...

The literature on public goods has shown that efficient outcomes are impossible if participation constraints have to be respected. This paper addresses the question whether they should be imposed. It asks under what conditions efficiency considerations justify that individuals are forced to pay...

We study how an optimal income tax and an optimal public-goods provision rule respond to preference and productivity shocks. A conventional Mirrleesian treatment is shown to provoke manipulations of the policy mechanism by individuals with similar interests. We therefore extend the Mirrleesian...
