Adoption of Technologies with Network Effects: An Empirical Examination of the Adoption of Automated Teller Machines
研究网络效应如何影响企业采纳新技术的时间，以银行采纳自动柜员机为例，发现分支机构和存款规模越大，银行越早采纳。
The literature on networks suggests that the value of a network is positively affected by the number of geographically dispersed locations it serves (the "network effect") and the number of its users (the "production scale effect").We show that as a result a firm's expected time until adoption of technologies with network effects declines in both users and locations.We provide empirical evidence on the adoption of automated teller machines by banks that is consistent with this prediction.Using standard duration models, we find that a bank's date of adoption is decreasing in the number of its branches (a proxy for the number of locations and hence for the network effect) and the value of its deposits (a proxy for number of users and hence for production scale economies).The network effect is the larger of the two effects.
