A Dynamic Game of R and D: Patent Protection and Competitive Behavior
用微分博弈分析n家企业行业中的研发动态最优资源配置，计算并讨论了投资规则的纳什均衡，对理解专利保护下的企业竞争行为有参考价值。
A theory of dynamic optimal resource allocation to R and D in an n-firm industry is developed using differential games. This technique represents a synthesis of the analytic methods previously applied to the problem: static game theory and optimal control. The use of particular functional forms allows the computation and detailed discussion of the Nash equilibrium in investment rules.
