Comparative Evidence on Corporate Governance Outcomes in the G20 Countries

The purpose of this study is to investigate the differences between developed countries in terms of corporate governance outcomes at aggregate and granular levels. The population of companies was collected from the database curated by Refinitiv. The sample was selected according to two criteria: the existence of governance scores for the financial year 2021 and the registration of a company in any of the G20 countries or the European Union. The results are presented by ranking the G20 countries based on four aggregate indicators and four granular indicators of corporate governance quality. While the differences regarding the aggregate indicators are not statistically strong, the intercountry differences on board independence, board gender diversity, board skills, and auditor tenure are especially relevant. The present article opens an avenue of research on international corporate governance linked to cultural dimensions, comparative legal systems, national approach to corporate social responsibility, and corporate governance principles.
