我们研究信息设计的有效性,以减少拥挤的社会服务迎合不同层次的需要的用户。在没有价格歧视和集中准入的情况下,供应商依赖于共享有关等待时间的信息来改善福利。我们考虑一个程式化的模型与不同的用户在他们的私人外部选项:低需求用户有一个可接受的外部选项的社会服务,whereashigh-needusers没有可行的外部选项。到达后,用户决定加入一个不可观察的先到先得队列来等待服务,或者离开并寻求她的外部选项。为了减少拥挤和改善社会结果,服务提供商试图说服更多的低需求用户利用他们的外部选择,从而更好地服务于高需求用户。我们描述了帕累托有效的信号机制,并比较他们的福利结果对几个基准。我们表明,如果任何一种类型是人口的绝大多数,那么信息设计并没有提供改善共享全部信息或没有信息。另一方面,当人口具有足够的异质性时,信息设计不仅在完全信息和无信息机制中处于帕累托支配地位,而且在某些制度中,它还实现了与“第一最佳”相同的福利,即了解用户类型的帕累托有效集中式准入政策。本文被收入管理和市场分析的Gabriel Weintraub接受。这项工作得到了美国国家科学基金会民用、机械和制造业创新部的支持[赠款CMMI-2002155和CMMI-2002156]。补充材料:数据和电子伴侣可在www.example.com上获得https://doi.org/10.1287/mnsc.2022.4548。
We study the effectiveness of information design in reducing congestion in social services catering to users with varied levels of need. In the absence of price discrimination and centralized admission, the provider relies on sharing information about wait times to improve welfare. We consider a stylized model with heterogeneous users who differ in their private outside options:low-needusers have an acceptable outside option to the social service, whereashigh-needusers have no viable outside option. Upon arrival, a user decides to wait for the service by joining an unobservable first-come-first-serve queue, or leave and seek her outside option. To reduce congestion and improve social outcomes, the service provider seeks to persuade more low-need users to avail their outside option, and thus better serve high-need users. We characterize the Pareto-efficient signaling mechanisms and compare their welfare outcomes against several benchmarks. We show that if either type is the overwhelming majority of the population, then information design does not provide improvement over sharing full information or no information. On the other hand, when the population is sufficiently heterogeneous, information design not only Pareto-dominates full-information and no-information mechanisms, in some regimes it also achieves the same welfare as the “first-best,” that is, the Pareto-efficient centralized admission policy with knowledge of users’ types.This paper was accepted by Gabriel Weintraub, revenue management and market analytics.Funding:This work was supported by the National Science Foundation, Division of Civil, Mechanical and Manufacturing Innovation [Grants CMMI-2002155 and CMMI-2002156].Supplemental Material:The data and e-companion are available at https://doi.org/10.1287/mnsc.2022.4548.
