最近的监管和技术变化表明，本地电信市场可能很快就会出现有利可图的进入机会。企业绕过活动，再加上普遍较高的商业费率，表明企业服务收入可能正在补贴居民接入本地网络。在监管机构允许大规模进入当地电信市场之前，他们需要了解当地电话服务费率是否存在交叉补贴。利用新英格兰电话公司提供的数据，本文检验了一组新的不需要观察独立成本的交叉补贴的充分条件。结果表明，商业服务收入补贴了近65%的郊区中心办公室的住宅服务提供。对于样本中的所有中心办公室，住宅到企业交叉补贴的充分条件都不成立。
Recent regulatory and technological changes suggest that the local telecommunications market may soon present opportunities for profitable entry. Bypass activity by businesses, combined with the generally higher business rates, suggests that business-service revenues may be subsidizing residential access to the local network. Before regulators allow wide-scale entry into local telecommunications, they need to know if local phone service rates exhibit cross subsidies. Using data supplied by New England Telephone, this article tests a new set of sufficient conditions for cross subsidization that do not require observations on stand-alone cost. The results indicate that business-service revenues subsidize residential-service provision at nearly 65% of the suburban central offices. The sufficient conditions for a residential-to-business cross subsidy fail for all central offices in the sample.
