The Consequences of Management Earnings Forecast Regulation : Stock Price Informativeness and Disclosure Externalities

We examine the consequences of a management earnings forecast regulation implemented in a staggered manner. The regulation substantially increases the directly affected firms' frequency of management forecasts. Nevertheless, approximately 14% of the directly affected firms fail to comply with the regulation (noncompliant firms). The regulation helps increase the stock price informativeness of the directly affected firms that issue a forecast. The regulation also helps increase the stock price informativeness of the noncompliant firms (a spillover), but we find no evidence of a similar spillover for the firms that are not required to issue mandatory forecasts in the post-regulation period
