讲座内容摘要：

We study the impact of mobile internet technology on analyst forecast performance. Mobile internet facilitates uninterrupted access to various types of information and provides productivity tools for professionals. As such, it can help financial analysts gain immediate access to information and integrate it into their forecasts, leading to improved forecast timeliness. Mobile internet may also allow analysts to gather or receive additional information more promptly, improving forecast accuracy. Our tests utilize the rollout of 3G mobile internet in the U.S. and include both continuous treatment and sharp-increase differences-in-differences models, comparing forecast characteristics for a given firm-year across analysts with varying degrees of access to mobile internet. Results indicate that enhanced access to mobile internet results in significant improvements in analysts’ forecast timeliness and accuracy. We link these improvements empirically to the rollout of productivity apps, and confirm their effect with a tool particularly pertinent for analysts, the Bloomberg app.

我们研究了移动互联网技术对分析师预测业绩的影响。移动互联网有助于不间断地访问各种类型的信息，并为专业人员提供生产力工具。因此，它可以帮助财务分析师立即获取信息，并将其集成到预测中，从而提高预测的及时性。移动互联网还可以让分析师更快地收集或接收更多信息，从而提高预测的准确性。我们的测试利用了3G移动互联网在美国的推出，比较了不同程度接入移动互联网的分析师对给定公司年度的预测特征。结果表明，移动互联网接入的增强显著提高了分析师的预测及时性和准确性。
