Jannis Bischof, ‘The effects of IFRS adoption on bank disclosure in Europe’, looks at the effects of adopting IFRS 7, Financial Instruments: Disclosures, for 171 banks (16 non-EU) in 28 European countries (three non-EU) for 2006 and 2007. The author finds that ‘the effects of IFRS 7 adoption substantially vary across countries’ and that ‘regulatory activity by national supervisory authorities explains some of these differences’. He comments that ‘Harmonization and, thereby, comparability of bank disclosures cannot be achieved by a common content of accounting standards alone; it is also necessary to agree on a uniform approach to the enforcement of those standards.’
