“…The studies on the adoption of IAS/IFRS by European companies investigate the implications of the introduction of this set of international accounting standards by adopting two main research approaches: a first group of studies focuses on the transition and implementation of IAS/IFRS and in particular it highlights their effects for firms (Jermakowicz, 2004;Street and Larson, 2004;Sucher and Jindrichovska, 2004;Vellam, 2004) and for local and international regulators (Weißenberger et al, 2004;Haller and Eierle, 2004;Shipper, 2005;Whittington, 2005); a second category investigates the financial reporting under IAS/IFRS with reference to the compliance to IAS/IFRS (Emenyonu and Gray, 1996;Dumontier and Raffounier, 1998;El-Gazzar et al, 1999;Murphy, 1999;Street and Bryant, 2000;Ashbaugh, 2001;Glaum and Street 2003;Tarca, 2004;Cuijpers and Buijink, 2005) and the quality of information under IAS/IFRS (Ashbaugh and Pincus, 2001;Hung and Subramanyam, 2004;Barth et al, 2005;Van Tendeloo and Vanstraelen, 2005).…”
