Audit quality in the Czech Republic
Pěkná, Martina ; Havel, Jiří (advisor) ; Hollmannová, Monika (referee)
Audit of statutory financial statements is mandatory for major part of big companies. Auditor ascertains the validity and reliability of information in the financial statements. Since stakeholders use financial statements for their decisions, quality of audit services is important for all users of financial statements. This thesis concerns about the quality of audit services in the Czech Republic. We focus on suppliers concentration on audit market using market concentration measures and based on these data we outline structure of audit market. Our findings suggest significant heterogeneity of supply side of audit market. We also examine the relationship between audit quality and cost of capital of audited companies when we expect that higher quality audit may decrease cost of capital of audited companies. For this purposes we build up unique data set of non- financial companies and design a model respecting the specifics of Czech financial market. Surprisingly, results are not consistent with those of existing research based on US and Chinese data when they suggest that there is no significant relationship between audit quality and cost of capital.

Response by Czech Auditors and Audit Regulators to the Financial Crisis
Chudá, Tatiana ; Hollmannová, Monika (advisor) ; Gutiérrez Chvalkovská, Jana (referee)
Auditors play an important role in the reliability of financial statements. Many investors and other financial information users rely on their opinion. During the financial crisis, auditors were critised since they did not warn the markets about financially distressed companies. In our thesis, we examine whether auditors change their behaviour during a financial crisis. Using our collected data for joint stock companies in the Czech Republic, we focus on frequency of modified and going concern opinions, amount of audit and non-audit fees charged by auditors, and audit reporting lag. Our audit fees model showed that there were significantly lower audit fees after the crisis than during the crisis years. The results also suggest that both Big 4 and non-Big 4 auditors increased their frequency of issuing modified opinions (most of which were going concern opinions) during the crisis period. In our logit going concern models for the individual years we observed change of the auditors' behaviour during the crisis years 2008-2010. We have also found out that Big 4 auditors increased their audit reporting lag in 2008 but our overall results suggest that the audit reporting lag was shorter during the crisis.
