Abstract: 

For excludable public goods, we propose simple mechanisms to uniquely implement a (core) stable and efficient production and cost-sharing outcome: consumers are asked to announce sequentially their minimal requested level of public good and a subscription towards its production. In one mechanism the subscriptions are order-independent and thus symmetric. The equilibrium outcomes induced by our mechanisms are immune to strategic deviations by coalitions. Keywords: Excludable public good, demand-subscription mechanism, implementation, stand alone core, coalition formation, strong equilibrium.
