摘要：This study aims to analyze the impact of adopting international accounting standards on the accuracy and dispersion of
analysts' forecasts in the Brazilian stock market. Data were extracted from the Institutional Brokers Estimate System
(IBES) database and reference forms of companies published on the Brazilian Securities and Exchange Commission's
website for the period 2000–2015. The difference-in-differences methodology was used to compare the results of
companies that voluntarily adopted the IFRS with those of companies that adopted the IFRS after the mandatory
adoption period. The results suggest that mandatory IFRS adoption contributed to an increase in the accuracy of
analysts' earnings forecasts for non-financial companies, while it did not significantly impact the dispersion of analysts'
forecasts. These findings suggest that IFRS adoption contributed to an increase in the quality of analysts' earnings
forecasts, providing investors with more security when utilizing this information for decision-making.
