Purpose This paper aims to analyse the implications of globalisation and the adoption of international standards (International Financial Reporting Standards IFRS) for accounting information quality. Design/methodology/approach This paper uses a sample of 329 banks across 29 countries leading up to and beyond the implementation of IFRS to test for related hypotheses. Findings First, banks’ financial statements are prepared on the basis of international standards as national economies are integrated when social norms are diffused. Building on these results, the second test suggests that the relatively high-quality earnings among banks in Africa during the period is attributable to the adoption of and interaction of IFRS with globalisation and the strategy of banks to diversify within and across interest and non-interest income. Originality/value The authors investigate how globalisation and the adoption of IFRS affect accounting information quality.
