In particular, the mandatory adoption of IFRS in the European Union has represented an
extraordinary opportunity for empirical studies. A certain number of studies have focused on the
effects of making IFRS mandatory in different countries at the same time. Aubert and Grudnitski
(2011), for instance, examine 13 countries in the European Union and 20 industries, but fail to
document a statistically significant increase in the value-relevance of accounting information after the
adoption of IFRS. Daske et al. (2008)
