“…In view of the discussion presented, the main objective of this study was to investigate whether the systematic risk of companies listed on the Brazilian Stock Exchange (B3) is affected by the quality of accounting information. As a secondary objective, we verified whether this risk was affected after the mandatory adoption of IFRS in Brazil, given that studies carried out in the country reveal controversial results regarding the increase in the quality of accounting information after mandatory adoption in 2008 (Silva, 2013;Gatsios, 2013;Cardoso, Souza, & Dantas, 2015;Rezende, Almeida, & Lemes, 2015;Silva, Brighenti, & Klann, 2018).…”
