IFRS adoption and financial reporting quality: a review of evidences in different jurisdictions

Conventional and commonly held wisdom with respect to the adoption of International Financial Reporting Standards (IFRS) is that they lead to improved financial reporting quality and comparability and thereby favorable economic consequences. There are however contradicting evidences disproving this conventional wisdom or rejecting its gross generalization over the entire jurisdictions harmonizing on IFRS. Driven by this fact, quests for knowledge about the dynamics and contexts that lead to differential effects of IFRS get momentum. In an attempt to explore the insight into the effects of international accounting harmonization by way of IFRS adoption, this paper reviews selected literatures on the consequences of IFRS adoption. This review discusses some empirical evidences that have been reported in various countries that include Europe, USA, United Kingdom, Germany, Spain, Norway, Greece, Poland, Belgian, France, Italian, Turkey, United Arab Emirates (UAE), Kuwait, Jordan, China, Malaysia, Australia, Hong Kong, New Zealand, Kenya and Nigeria. Our review focuses on the aspects of value relevance, disclosure quality, cost of capital, earning management and financial statement impact due to the IFRS adoption. This review reveals that the economic consequences of IFRS adoption is significantly different though its impact reported to be positive in majority of cases. There are also notable number of studies that report indifferent and or negative effects of IFRS adoption. When IFRS studies report mixed evidence with respect to value relevance of book value of equity and earing, book value of equity supersedes the earning parameters. IFRS are found to supersede many other domestic financial reporting standards in terms of amount and the quality of disclosures in financial statement. This review also obtains that IFRS's impact on the reduction of cost of capital depends on financial reporting incentives, law enforcement, types of legal systems and various other country-specific and capital market characteristics. Further, though there are some evidences to the contrary, the quality of earnings reported under IFRS has been established to be superior to other local standards
