Dynamic Mixed Duopoly: A Model Motivated by Linux vs. Windows
分析一个利润最大化企业与一个零价格（或边际成本）竞争者互动的动态混合双寡头模型，受Linux与Windows竞争启发，强调需求侧学习效应带来的动态规模经济，并刻画均衡及比较静态与福利效应。
This paper analyzes a dynamic mixed duopoly in which a profit-maximizing competitor interacts with a competitor that prices at zero (or marginal cost), with the cumulation of output affecting their relative positions over time. The modeling effort is motivated by interactions between Linux, an open source operating system, and Microsoft’s Windows and consequently emphasizes demand-side learning effects that generate dynamic scale economies (or network externalities). Analytical characterizations of the equilibrium under such conditions are offered, and some comparative static and welfare effects are examined.
