Bandwagon Effects and Long Run Technology Choice
提出一类“从众博弈”，推广了多于两种技术且存在部分兼容时的网络外部性概念，并用随机演化方法分析长期均衡，找出全局成对风险占优技术成为长期均衡的条件。
We introduce a class of “bandwagon games” which generalizes the notion of network externalities when there are more than two competing technologies and various degrees of partial compatibilities among them. We then apply the stochastic evolutionary approach to this class of games. We determine the conditions under which aglobally pairwise risk-dominanttechnology is the long-run equilibrium (LRE). We also show the conditions under which one technology takes over another technology by directly switching consumers from the latter to the former (also calleddirect domination). Parametric examples illustrate the properties of the technology which is the LRE.Journal of Economic LiteratureClassification Numbers: C72, C73.
