R&D Networks: Theory, Empirics, and Policy Implications
研究了企业通过研发合作降低生产成本并在产品市场竞争的模型，完整刻画了纳什均衡，确定了最优研发补贴方案，并用企业面板数据估计模型，比较了针对性补贴与非歧视性补贴的效果。
We analyze a model of R&D alliance networks where firms are engaged in R&D collaborations that lower their production costs while competing on the product market. We provide a complete characterization of the Nash equilibrium and determine the optimal R&D subsidy program that maximizes total welfare. We then structurally estimate this model using a unique panel of R&D collaborations and annual company reports. We use our estimates to study the impact of targeted versus nondiscriminatory R&D subsidy policies and empirically rank firms according to the welfare-maximizing subsidies they should receive.
