Regulation and Preemptive Technology Adoption
两家竞争企业决定是否及何时采纳新技术，考虑成本下降和利润变化。价格与进入管制通过削弱先发策略的吸引力来减缓技术采纳，有时甚至改变采纳顺序。以有线电视和电话公司采纳光纤技术为例，取消跨业禁令取决于电话公司能否实施更优技术。
Two rival firms must decide if and when to adopt a new technology, knowing how adoption costs decline over time and how profit flows vary with adoption patterns. In many cases, price and entry regulations beneficially slow technology adoption by making preemption strategies less attractive. In some cases, these regulations can so discourage a firm from preemption as to change the order in which firms adopt new technologies, speeding one firm's adoption date and slowing the other's. In the context of a particular scenario for cable and telephone companies' adoption of new fiber optic technologies, the case for lifting the cross-ownership ban depends on the extent to which telephone companies are able to implement a superior technology. Reregulation of cable companies strengthens this case.
