Regulations and audit opinions: Evidence from EU banking institutionsRegulations and audit opinions: Evidence from EU banking institutions Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-272013enIn this study, we empirically investigate the relationship between financial and auditing requirements, capital requirements, official supervisory power, and the likelihood of receiving a qualified audit opinion. The sample consists of 71 qualified financial statements and 17,526 unqualified ones, from 3,642 banking institutions operating in 15 old and new EU countries over the period 1999–2006. The results indicate that financial and auditing requirements have a negative influence, while supervisory power has a positive impact, on the likelihood of qualified audit opinions. Concerning capital requirements, we find that only initial stringency has an impact on audit opinions.http://creativecommons.org/licenses/by/4.0/Computational Economics413387-405 Pasiouras Fotios Πασιουρας Φωτιος Chrysovalantis Gaganis Charalambos Spathis Springer Verlag
