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 the relation between mechanism design and voting in public-good provision. If incentive mechanisms must satisfy conditions of coalition-proofness and robustness, as well as individual incentive compatibility, the participants' contributions to public-good provision can only depend on...

In a large economy, a first-best provison rule for a public good is robustly implementable with budget balance because no one individual alone can affect the aggregate outcome. First-best outcomes can, however, be blocked by coalitions of agents acting in concert. With a requirement of immunity...

We study the provision of public goods. Different public goods can be bundled provided there is enough capacity, i.e. resources to pay for all the public goods in the bundle. The analysis focuses on the all-or-nothing-mechanism: Expand provision as much as resource feasible if no one vetoes -...

We propose a new family of mechanisms, whereby players may give more or less directly to one another. A cornerstone case is the regular linear public goods mechanism (LPGM), where all contribute into a single common group account, the total amount of which is then distributed equally among...

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...
