Persistence of Accounting Information in Regulated and Unregulated Firms in the Brazilian Economy
Main Article Content
Abstract
Objective: this study aims to analyze differences in the persistence of accounting information between firms operating in regulated and unregulated sectors of the Brazilian economy. Methods: the sample comprises, on average, 276 companies listed on B3, with data spanning from 2011 to 2022. Ordinary least squares (OLS) regression tests were performed, and a total of 20 models were analyzed. Persistence was measured using two different models, focusing on earnings, cash flows, and accruals. Fifteen dummy variables were constructed and grouped into four categories: regulation, purely economic vs. economic and accounting regulation, national regulatory agencies, standardized chart of accounts, and individual dummies for each regulated sector. Results: firms in the sample exhibit persistence in earnings, cash flows, and accruals. Regulated firms demonstrate higher earnings and cash flow levels compared to unregulated firms; however, these are less persistent, suggesting lower quality of accounting information in regulated sectors. Conclusions: the findings indicate that firms may prioritize performance at the expense of accounting information quality. These results support the development of regulatory policies and may aid the decision-making processes of investors and creditors.
