We find that Sarbanes-Oxley (SOX) had two significant effects on the audit market for nonpublic entities. The first short-run effect stems from inelastic labor supply coupled with an audit demand shock from public companies. As a result, private companies reduced their use of attested financial...

We provide evidence on the long standing concern on auditor conflicts of interest from providing non-audit services (NAS) to audit clients by using rarely explored NAS fee data from 1978-80 Using this earlier setting, we find cross-sectional evidence of improved earnings quality when auditors...

By the end of the 20th century, the competitive structure of the public accounting industry evolved into a tight oligopoly. We predict a reversal of this trend, because new issuers of public equity, who steadily replace legacy companies in the set of public companies, display less verifiable...

We employed a frame-theoretic framework to formulate and analyze a number of tax audit rules, especially the lowest income reporter audited rule. We explicitly considered the auditor's resource constraint to choose one target from a continuous type of taxpayer. We then tested the theoretical...

The paper studies the relative effectiveness of extrinsic monetary disincentives and intrinsic non-monetary disincentives to corruption. In doing so, we also test the Beckarian prediction that at the same level of expected payoff, a low probability of detection with high penalty is a stronger...

This paper studies the effect of endogenous audit probabilities on reporting behavior in a face-to-face compliance situation such as at customs. In an experimental setting in which underreporting has a higher expected payoff than truthful reporting we find an increase in compliance of about 80%...

We investigate the strategic decision making of audit firms in a tendering process. In particular, we are interested in how audit firms behave to acquire audit clients and which audit quality is ensured. Our main findings are manifold. First, if two big audit firms are competing, we do not...

Contract audits aimed at reducing information asymmetry and transaction costs are frequently used in imperfect markets such as defense procurement. This contradicts predictions from standard economic theory. We conduct a laboratory experiment to investigate this paradox. Our laboratory setup...
