Product Differentiation in Auditing
Auditor Choice in the Market for Unseasoned New Issues
Description:... A fundamental question with respect to the market for audit services is whether or not such services are homogeneous across suppliers ... In this monograph, we review the basic principles and findings concerning differentiated product markets as they have been developed in the economic literature. Using Lancaster's characteristics framework, we posit that the audit service contains several attributes which are valued by top management. A key attribute is "credibility", which is communicated by an audit firm's brand name and is identified with the power of an auditor's test ... We posit that, along with other product characteristics, the power of test varies systematically across audit firms. Hypotheses concerning the demand for different audit service specifications (qualities) are developed in a context where companies are changing their capital structure through an initial public offering of common shares. These hypotheses are tested using a sample of 469 U.S. corporations which first "went public" during 1981. The results are consistent with the existence of differential audit services.
