Who Matters in Coordination Problems?
研究在协调问题中，如何以最小成本通过补贴实现成功协调，发现最优补贴对象是那些对他人施加高外部性、同时受他人影响低的人。
Agents face a coordination problem akin to the adoption of a network technology. A principal announces investment subsidies that, at minimal cost, attain a given likelihood of successful coordination. Optimal subsidies target agents who impose high externalities on others and on whom others impose low externalities. Based on the analysis of the role of strategic uncertainty in coordination processes, we provide a methodology that can be used to find the optimal targets for a variety of interventions in a large class of coordination problems with heterogeneous agents.
