“…Building on this statement, US empirical studies provide generalised evidence that auditor size is positively related with audit quality using different sources such as audit premiums (Simunic, 1980;Moizer, 1997;DeFond, Francis and Wong, 2000;Ferguson, Francis and Stokes, 2003), the level of sanctions (Palmrose, 1988;Feroz, Park and Pastena, 1991), audit thresholds (Francis and Krishnan, 1999), abnormal accruals (Becker et al, 1998;Francis, Maydew and Sparks, 1999) and the market value of earnings surprises (Teoh and Wong, 1993). As a consequence of this, auditor size has been widely accepted as a good proxy for audit quality in the literature (DeFond, 1992;Mutchler, Hopwood and McKeown, 1997;Francis, Maydew and Sparks, 1999;Callaway, Lulseged and Nowlin, 2002;Vander Bauwhede and Willekens, 2004;Tilis, 2005).…”
