When Do Sell‐side Analyst Reports Really Matter? Shareholder Protection, Institutional Investors and the Informativeness of Equity Research
研究了国家监管环境和机构投资者的监管背景如何影响卖方分析师报告的信息价值，发现投资者保护越强，分析师研究的信息含量越高。
Abstract We examine whether the informativeness of sell‐side analyst reports depends on the strength of the regulatory environment of a country and the regulatory background of the institutional investors of a company. Based on both measures that we use to proxy the informativeness of analyst research (i.e., short‐term market reaction and forecast errors with respect to corporate earnings), our results show that the information value of research increases as the level of investor protection increases. This result is robust to different specifications of investor protection. We further demonstrate that analyst forecasts are more (less) valuable when the majority of institutional investors are from strong (weak) investor protection countries.
