We revisit the problem of providing a pure public good in economies involving two agents, under the assumption that preferences are quasilinear. We characterize the class of strategy-proof, anonymous and feasible mechanisms that are not dominated by another strategy-proof, anonymous and feasible...

In recent years, the increasing awarding of patents has captured the attention of scholars operating in different fields. The economic literature has studied the causes of this proliferation; we propose an entry game focusing on one of the consequences, showing how an incumbent may create a...

The paper proves that (static) non cooperative foreclosing or collusive equilibria in the upstream roaming market are sustainable even if there exist more incumbents. In particular we focus on the complementarity that occurs when an incumbent upstream signs a roaming agreement with a new...
