Recent high profile cases of management fraud resulting in the collapse of large international corporations have lead to increased calls for an improved corporate governance system, including in Switzerland. Assuming asymmetric information and potentially opportunistically acting managers, the verification of external reporting carried out by independent and qualified auditors builds the foundation for a sound communication on capital markets. These auditors are also, however, economic agents and as such may be biased in the auditing process. This doctoral thesis, therefore, investigates methods to measure and control audit quality. Drawing on the theoretical grounds of current literature, an empirical study focuses on the perception of audit services from chief financial officers, boards of directors and auditors of companies listed on the Swiss Stock Exchange, as well as from financial analysts. Using Marten’s symmetric gap-model for measuring audit quality, this study explains statistically significant quality gaps relating to the perception, assessment and expectation of various attributes of the audit function, which are relevant to the overall quality assessment. These results then lead to a discussion on the question of whether quality uncertainty (i.e. adverse selection) might exist in the audit market and whether audit committees have an impact on the perceived audit quality. Finally, this thesis investigates whether the audit function is relevant to the capital market.
