This paper deals with the existence of anonymous mechanisms to realize the Lindahl correspondence. We consider, in turn, constant and decreasing returns to scale technologies for producing public goods. In each case, we provide a continuous (but not smooth) and weakly balanced mechanism, which...

This paper considers the issue of a catastrophic environmental collapse and the way one should deal with it. In the model used here, one faces the choice to cross or not a critical threshold of pollution, which consequences are a definitive destruction of some environmental characteristic. The...

In this paper, we amend the standard model of law enforcement, by introducing a marginal cost of public funds. We derive the associated optimal enforcement policy. We show that, as the marginal cost of public funds increases, the objective of raising public funds gradually replaces that of...

This note provides a simple characterization of the optimal extraction of a non-renewable resource. The proposed formula determines the solution in its feedback form. It is shown to hold for a large class of models, as long as the utility is stock-independent.
