滚转和共享数据计划的经济分析
Economic Analysis of Rollover and Shared Data Plans
AI总结：
本文通过博弈论模型分析无线服务提供商在提供滚转和共享数据计划时的时机决策，考虑了新用户到达和动态用户流失的影响，发现市场占有率小的运营商倾向于率先推出新计划以吸引用户，而市场占有率大的运营商则倾向于推迟推出以避免短期收入损失。
摘要：
在当今快速增长的数据市场中，无线服务提供商（WSPs）通过宣布创新的数据计划激烈竞争以吸引用户。两种最受欢迎的创新数据计划是滚转计划和共享计划，前者允许用户将未使用的数据配额保留到下个月，后者允许家庭成员共享未使用的数据。作为提供此类数据计划的先驱，WSPs会立即面临现有用户因较少的数据超支而造成的收入损失，但通过吸引新用户和那些在其他WSPs的用户，其市场份额会逐渐增加。在某些国家，WSPs在提供此类创新数据计划时存在不对称的时机安排，而在其他市场，WSPs则有对称的时机安排或没有计划。这引发了问题：为什么以及何时竞争性的WSPs应提供新的数据计划。本文通过考虑新用户到达和动态用户流失，对WSPs提供创新数据计划的时机进行博弈论建模和分析。我们的均衡分析显示，市场占有率小的WSP倾向于率先宣布创新数据计划以吸引更多用户，而市场占有率大的WSP倾向于推迟宣布以避免立即的收入损失。在新用户众多的市场中，市场占有率相似的WSPs会同时提供数据计划，但面对少数新用户时，这些WSPs可能不会提供任何新计划。令人惊讶的是，WSPs的利润可能随着新用户数量的增加而减少，他们可能无法从创新数据计划的选项中获益。最后，不同于滚转数据计划，我们显示共享数据计划的时机进一步取决于用户的构成。
英文摘要：
In today's growing data market, wireless service providers (WSPs) compete severely to attract users by announcing innovative data plans. Two of the most popular innovative data plans are rollover and shared data plans, where the former plan allows a user to keep his unused data quota to next month and the latter plan allows users in a family to share unused data. As a pioneer to provide such data plans, a WSP faces immediate revenue loss from existing users who pay less overage charges due to less data over-usage, but his market share increases gradually by attracting new users and those under the other WSPs. In some countries, WSPs have asymmetric timing for providing such innovative data plans, while some other markets' WSPs have symmetric timing or no planning. This raises the question of why and when the competitive WSPs should offer the new data plans. This paper provides game theoretic modelling and analysis of the WSPs' timing of offering innovative data plans, by considering new user arrival and dynamic user churn between WSPs. Our equilibrium analysis shows that the WSP with small market share prefers to announce the innovative data plan first to attract more users, while the WSP with large market share prefers to announce later to avoid the immediate revenue loss. In a market with many new users, WSPs with similar market shares will offer the data plans simultaneously, but these WSPs facing few new users may not offer any new plan. Perhaps surprisingly, WSPs' profits can decrease with new user number and they may not benefit from the option of innovative data plans. Finally, unlike rollover data plan, we show that the timing of shared data plan further depends on the composition of users.
