In the context of a process of change in accounting rules and standards, the Institutional Theory of Douglas North provides help in understanding the adoption of IFRS, since the new international accounting standards to harmonize the accounting practices of various countries seeking improved effectiveness of accounting.

As a result of the research, it was not possible to verify reduction in the diversity of financial statements of listed companies in the capital market in Brazil - which differs from the findings of Jones and Finley (2011 ), which indicated some statistically significant reductions in the variability of the measurements after IFRS, even controlling factors such as company size, industry and status of adoption.
