A planner chooses an allocation of a divisible resource and charges agents based on their reported type. We discover and describe the set of dominant-strategy incentive-compatible (strategy-proof) mechanisms when the planner has the ability to observe the true type of agents ex-post and punish...

We consider the problem of sharing the cost of connecting a large number of atomless agents in a network. The centralized agency elicits the target nodes that agents want to connect, and charges agents based on their demands. We look for a cost-sharing mechanism that satisfies three desirable...
