Independence in Appearance and in Fact: An Experimental Investigation*

In this study, we use experimental markets to assess the effect of the Security and Exchange Commission's (SEC's) new independence rule on investors' perceptions of independence, investors' payoff distributions, and market prices. The new rule requires client firms to disclose in their annual proxy statements the amount of nonaudit fees paid to their auditors. The new disclosure is intended to inform investors of auditors' incentives to compromise their independence. Our experimental design is a 2 3 between‐subjects design, where we control the presence (unbiased reports) or absence of auditor independence in fact (biased reports). While independence in fact was not immediately observable to investors, we controlled for independence in appearance by varying the public disclosure of the extent of nonaudit services provided by the auditor to the client. In one market setting, investors were not given any information about whether the auditor provided such nonaudit services; in a second setting, investors were explicitly informed that the auditor did not provide any non‐audit services; and in a third setting, investors were told that the auditor provided nonaudit services that could be perceived to have an adverse effect on independence in fact. We found that disclosures of nonaudit services reduced the accuracy of investors' beliefs of auditors' independence in fact when independence in appearance was inconsistent with independence in fact. This then caused prices of assets to deviate more from their economic predictions (lower market efficiency) in the inconsistent settings relative to the no‐disclosure and consistent settings. Thus, disclosures of fees for nonaudit services could reduce the efficiency of capital markets if such disclosures result in investors forming inaccurate beliefs of auditor independence in fact ‐ that is, auditors appear independent but they are not independent in fact, or vice versa. The latter is the maintained position of the American Institute of Certified Public Accountants (AICPA), which argued against the new rule. Further research is needed to assess the degree of correspondence between independence in fact and independence in appearance.     

Evidence of Industry Scale Effects on Audit Hours,Billing Rates,and Pricing

Using a proprietary data set consisting of all private firm audit engagements in 2000 from one Big 4 firm in Belgium, we investigate (i) whether audit office industry scale is associated with a reduction of total, partner, and staff audit hours and thus with efficiency gains triggered by organizational learning from servicing more clients in an industry and (ii) whether the extent of efficiency pass‐on from the auditor to its clients depends on the audit firm's market power. We find that auditor office industry scale is associated with efficiency gains and a reduction of the variable costs (i.e., fewer total audit hours, partner hours, and staff hours), ceteris paribus. Our results also suggest that, on average, realized efficiencies are entirely passed on, as evidenced by a nonsignificant effect of auditor industry scale on the auditor's billing rate. Furthermore, we find that the extent of the efficiency pass‐on decreases with the market power of the audit firm in the industry market segment as we document a higher billing rate for auditors with high market power (versus low market power). In addition, we find that the lower audit hours associated with auditor industry scale do not compromise audit quality.     

A Multiperiod Model and Experimental Evidence of Independence and “Lowballing”*

Abstract. Auditors, regulators, and academics are interested in the pricing practice of “lowballing” and its relationship to auditor independence. Several analytical models have examined these issues. However, these theories have gone untested primarily due to a lack of field data concerning important environmental variables. In this study, a multiperiod model of lowballing and independence is developed and tested in laboratory markets via the experimental economics methodology. The study contributes to the literature in two respects. First, it represents one of the first studies providing empirical evidence and theory testing of the relationship between lowballing and independence. Second, the model presents a new rationale for low-ball pricing and its relationship to auditor independence. Lowballing and impairment of independence, occurring without exogenous transaction costs, are caused by positing cross-sectional variation in audit cost and quality and an informational advantage that accrues to an incumbent auditor-client pair regarding future variation in these audit dimensions. The model is operationalized in a multiperiod laboratory market consisting of multiple sellers and buyers. Sixteen markets are conducted to test price and reporting predictions of the model. The markets strongly exhibit lowballing behavior, but the exact price predictions are generally not supported. The markets also support reporting predictions, with sellers deviating from truthful reporting (impairing their independence) only when additional future profits are greater than the additional cost of misreporting.

Auditor underreporting of time and moral reasoning: An experimental lab study*

Abstract. This paper introduces the theory of moral reasoning as a valid determinant of the underreporting of audit time. In an experimental lab design for a sample of 88 auditors from a national public accounting firm, actual underreporting on an audit task was observed. Findings show that underreporting is systematically related to the auditor's level of moral reasoning as measured by the Defining Issues Test (DIT). Here those with relatively low DIT scores were shown to underreport most severely. Results also show that although an unattainable time budget affects behavior, peer pressure has the most significant impact on underreporting. The present study makes three important contributions to the auditing and psychology literature. First, it establishes the significance of peer pressure as an antecedent to underreporting. Second, it shows that an auditor's moral reasoning explains actual underreporting behavior under conditions of work-related pressure. Third, it reveals marked underreporting under simulated audit conditions.     

Crash Risk and the Auditor–Client Relationship

This study examines whether the term of the auditor–client relationship (i.e., auditor tenure) is associated with future stock price crash risk measured both ex ante and ex post. Using a large sample of U.S. public firms with Big 4 auditors, we find robust evidence that auditor tenure is negatively related to one‐year‐ahead stock price crash risk. The evidence is consistent with monitoring‐by‐learning where development of client‐specific knowledge over the term of the auditor–client relationship enhances auditors’ ability to detect and deter bad news hoarding activities by clients, thereby reducing future crash risk. This result holds even after controlling for endogeneity of the tenure/crash risk relation. We further provide evidence indicating that option market investors do not fully incorporate the information contained in the term of auditor–client relationship in predicting future stock price crash risk. Our empirical results have important policy implications for regulators concerned with ensuring auditor independence.     

Future Nonaudit Service Fees and Audit Quality

Prior to the Sarbanes–Oxley Act of 2002, audit partners experienced economic pressure to grow revenue from the sale of nonaudit services to their audit clients. To an auditor who is highly rewarded for revenue generation and growth, nonaudit services may represent a particularly strengthened economic bond with the client. Prior research shows that, in general, nonaudit service fees received in the current period do not impair audit quality. We examine a different setting. We propose that auditor independence can become impaired, and audit quality compromised, when clients that currently purchase relatively low amounts of nonaudit services, increase their purchases of nonaudit services from the auditor in the subsequent period. We test our prediction in the context of earnings management as a proxy for audit quality, measured by (a) performance‐adjusted discretionary accruals and (b) classification shifting of core expenses. Our results indicate that prior to the Sarbanes‐Oxley Act, rewards to the auditor in the form of future additional nonaudit service fees from current‐year high fee‐growth‐opportunity clients adversely affects audit quality. This effect is particularly strong among companies with powerful incentives to manage earnings. Our findings indicate that regulators should consider the multiperiod nature of the client–auditor relationship when contemplating policies that restrict nonaudit services, as well as the overall environment in which audit partners operate. This might include partner compensation arrangements that put pressure on audit partners to focus on increasing revenue at the expense of audit quality.     

Auditor Reputation,Auditor Independence,and the Stock‐Market Impact of Andersen's Indictment on Its Client Firms*

In this paper, we study a broad sample of Arthur Andersen clients and investigate whether the decline in Andersen's reputation, due to its criminal indictment on March 14, 2002, adversely affected the stock market's perception of its audit quality. Because these reputa‐tional concerns are more of an issue if an auditor's independence is impaired, we investigate the relationship between the abnormal market returns for Andersen clients around the time of the indictment announcement and several fee‐based measures of auditor independence. Our results suggest that when news about Andersen's indictment was released, the market reacted negatively to Andersen clients. More importantly, we find that the indictment period abnormal return is significantly more negative when the market perceived the auditor's independence to be threatened. We also examine the abnormal returns when firms announced the dismissal of Andersen as an auditor. Consistent with the audit quality explanation, we document that when firms quickly dismissed Andersen, the announcement returns are significantly higher when firms switched to a Big 4 auditor than when they either switched to non‐Big 4 auditors or did not announce the identity of the replacement auditor. Our empirical results support the notion that auditor reputation and independence have a material impact on perceived audit quality and the credibility of audited financial statements, and that the market prices this.     

Nonaudit Services and Earnings Conservatism: Is Auditor Independence Impaired?*

We examine whether the provision of nonaudit services (NAS) by incumbent auditors is associated with a reduction in the extent to which earnings reflect bad news on a timely basis (that is, news‐based conservatism). Reduced conservatism is expected to occur if relatively high levels of NAS result in reduced auditor independence and, ultimately, lower‐quality auditing. Because client‐specific demand for NAS is expected to vary, our proxy for the auditor‐client economic bond is the extent to which NAS purchases (relative to audit fees) are greater or less than expected. Using several different methods for identifying news‐based conservatism, we consistently find that higher than expected levels of NAS are not associated with reduced conservatism. This result is robust to allowing for endogenous NAS demand, as well as several explicit factors that may be associated with differences in conservatism. Similar conclusions arise from tests that use alternative measures of the economic bond between auditors and their clients, as well as in tests confined to either the Big 6 or non‐Big 6 audit firms. Our results are consistent with factors such as market‐based incentives, the threat of litigation, and alternative governance mechanisms offsetting any expected benefits to the audit firm from reducing its independence. We therefore conclude that recent legislative intervention aimed at restricting the supply of NAS is unlikely to result in increased independence in fact, although independence in appearance may be improved.     

Auditor Responses to Shareholder Activism

In this paper, we investigate how auditors respond to shareholder activism against their clients. Our study is important because activism may be viewed by auditors as a source of increased engagement risk, thereby impacting audit outcomes. The potential relationship between shareholder activism and audit outcomes leads us to predict that activism targets will pay higher audit fees and also will be more likely to receive adverse internal control opinions (ICOs) and first‐time going concern opinions (GCOs). Our results, which support all three predictions, suggest that the public scrutiny associated with activism campaigns heightens auditors' concerns about reputational damage and litigation risk. Consistent with this notion, we find that activism targets are more likely to experience accounting‐related lawsuits. We also find that the increased likelihood of adverse ICOs documented in our baseline tests reflects higher‐quality reporting rather than increased auditor conservatism. Overall, our findings suggest that activism campaigns spur auditor diligence while also increasing the possibility of negative outcomes that may not be fully anticipated by activist investors.     

Social Learning in Beauty‐Contest Games

We study the impact of social learning on the depth of reasoning in an experimental beauty‐contest game. Naive advice and observation of others' decisions as two forms of social learning trigger faster convergence to the equilibrium. We find that subjects who receive advice outperform uninformed subjects permanently, whereas subjects who observe others' past behavior before making their decision only have a temporary advantage over uninformed subjects. A series of control‐treatments and simulations indicate that the latter result is due to subjects failing to make the most out of observing others.     

An Experimental Investigation of Approaches to Audit Decision Making: An Evaluation Using Systems‐Mediated Mental Models*

The objective of this research is to articulate a decision‐making foundation for the systems audit approach. Under this audit approach, the auditor first gains an understanding of the auditee's economic environment, strategy, and business processes and then forms expectations about its performance and financial reporting. Proponents of this audit approach argue that decision making is enhanced because the knowledge of the system allows the auditor to focus on the most important risks. However, there has not been an explicit framework to explain how systems knowledge can enhance decision making. To provide such a framework, we combine mental model theory with general systems theory to produce a hypothesis we refer to as a systems‐mediated mental model hypothesis. We test this hypothesis using experimental economics methods. We find that (1) subjects make systematic errors under the setting without an organizing framework provided by the systems information, and (2) the presence of an organizing framework results in lower reporting errors. Importantly, the organizing framework significantly enhances decision making in the settings where the environment changed. Establishing a decision‐making foundation for systems audits can provide an important building block that, in part, can contribute to the development of a more effective and efficient audit technology ‐ an important objective now when audits are facing a credibility crisis.     

Experimental Evidence of the Impact of Increasing Auditors' Legal Liability on Firms' New Investments*

This laboratory market study examines the potential effect of increasing auditors' liability on firms' new investments. The experimental hypotheses are derived from Shibano's 2000 model, which predicts that an increase in auditors' liability will decrease the frequency of audit failures and may decrease firms' new investments if the liability level is “excessive”. Results from three experimental market settings (with low, medium, and high liability levels) suggest two major conclusions. First, firms' new investments increase significantly when auditors' liability level increases from low to medium, and decrease significantly as the liability level increases from medium to high. This result provides support for the argument that adequate auditor liability is necessary to motivate firms to invest in new projects. Excessive liability, however, may discourage firms from making new investments. Second, the frequency of audit failure decreases insignificantly when auditors' liability increases. These two results have an important policy implication: the benefit of imposing high liability on the auditor (i.e., an insignificant decrease in audit failure) may be more than offset by its cost (i.e., a significant decrease in new investments).     

Consumer Rationing and Cournot Outcomes: Experimental Evidence

We report the results of duopoly market experiments where firms first commit to capacities and then compete in prices. The theoretical literature pertaining to these duopoly models suggests that the way residual demand is rationed is fundamental to the character of equilibrium outcomes when capacity costs are sufficiently low. The experiments test this prediction by varying capacity cost and demand‐rationing schemes. We find that residual demand rationing does not significantly impact the capacity choices of experimental subjects, although it does affect pricing. Regardless of rationing scheme, the Cournot outcome is common with high capacity costs and rare with low capacity costs.     

Market Structure and Audit Fees: A Local Analysis*

This study conducts a local analysis of the relation between market structure and audit fees. The research question of interest to us is how audit fees are determined by each practicing local office, after taking into account the auditor's own position in a local market and the influence exerted by his or her clients. Appealing to the economic theories of monopoly and monopsony power, we hypothesize a positive audit fee‐concentration relation, and a negative audit fee‐client influence relation. Results indicate that auditor market concentration is positively associated with the non‐Big 6 audit fees but is unrelated to the Big 6 audit fees. Evidence is mixed concerning the client influence hypothesis. When this construct is proxied by the number of rival auditors operating within a geographic area centered on the municipality, the prediction of negative audit fee‐client influence relation is strongly supported for both groups of auditors. Results are much weaker using measures developed based on the relative importance of a municipal client to its auditor's audit portfolio. The issues addressed in this study are important at a time when the Canadian municipal sector is undergoing major changes because of municipal amalgamation, altering the underlying market structure for audit services and the bargaining position of a municipality vis‐Ã‐vis its auditor. More broadly speaking, our analysis implies that when assessing an auditor's report for signs of client pressure, the professional oversight bodies and regulatory authorities need to consider the relative, rather than the absolute, bargaining position of the client in question.     

Auditor Fees and Fraud Firms

The issue of whether auditor fees affect auditor independence has been extensively debated by regulators, investors, investment professionals, auditors, and researchers. The revised Securities and Exchange Commission (SEC) requirements that resulted from the implementation of the Sarbanes‐Oxley Act (2002) limit nonaudit services (NAS) and mandate NAS fee disclosure. The SEC's requirements are based on the argument that auditor independence could be impaired—and hence audit quality may be reduced—when auditors become economically dependent on their clients or audit their own work. Economic bonding leads to reduced independence, which can lead to reduced audit quality. We study a sample of firms sanctioned by the SEC for fraudulent financial reporting in Accounting and Auditing Enforcement Releases (SEC‐sanctioned fraud firms) and examine whether there is a relationship between auditor fee variables and the likelihood of being sanctioned by the SEC for fraud. We use SEC sanction as a measure of audit quality that has not previously been used in the auditor fee literature and is more precise than some of the other proxies used for flawed financial/auditor reporting. We find, in univariate tests, that fraud firms paid significantly higher (total, audit, and NAS) fees. However, in multivariate tests, when controlling for other fraud determinants and endogeneity among the fraud, NAS, and audit fee variables, we find that while NAS fees and total fees are positively and significantly related to the likelihood of being sanctioned by the SEC for fraud, audit fees are not. These findings suggest that higher NAS fees may cause economic bonding, thereby leading to reduced audit quality. Our findings of significantly higher NAS fees and total fees in fraud firms hold after controlling for latent size effects and other rigorous testing. These results contribute to the literature that examines the SEC's concerns regarding NAS and can be used by policy makers for additional consideration.     

Home Country Investor Protection,Ownership Structure and Cross‐Listed Firms' Compliance with SOX‐Mandated Internal Control Deficiency Disclosures

We examine whether home country investor protection and ownership structure affect cross‐listed firms' compliance with SOX‐mandated internal control deficiency (ICD) disclosures. We develop a proxy for the likelihood of cross‐listed firms' ICD misreporting during the Section 302 reporting regime. For cross‐listed firms domiciled in weak investor protection countries, we have three main findings. First, firms whose managers control their firms and have voting rights in excess of cash flow rights are more likely to misreport ICD than other firms during the Section 302 reporting regime. Second, there is a positive association between the likelihood of ICD misreporting and voluntary deregistration from the SEC prior to the Section 404 effective date. Third, for firms that chose not to deregister, there is a positive association between the likelihood of ICD misreporting and the reporting of previously undisclosed ICDs during the Section 404 reporting regime. We do not find similar evidence for cross‐listed firms domiciled in strong investor protection countries. Our findings are consistent with the hypothesis that, for cross‐listed firms domiciled in weak investor protection countries, managers who have the ability and incentive to expropriate outside minority shareholders are reluctant to disclose ICDs in order to protect their private control benefits. The results of our study should be of interest to regulators who wish to identify noncompliant firms for closer supervision, investors who wish to identify ex ante red flags for poor financial disclosure quality, and researchers who wish to understand the economic forces governing cross‐listed firms' financial disclosure behavior.     

声誉能解决医疗保险的“双刃剑”难题吗？——来自实验的证据

医疗保险虽然有利于提高医疗卫生服务的可及性和公平性，但也滋生了严重的道德风险问题。文章基于医疗服务的信任品属性，利用实验方法刻画了商业保险和社会保险两种保险形式，并通过对比私人信息和公开信息探究了加强声誉建设对解决医疗保险“双刃剑”难题的作用。实验结果表明，首先，商业保险和社会保险均会导致医患双方的道德风险问题，且商业保险更严重。其次，声誉加强有利于缓解保险的道德风险，其作用机制在不同保险条件下有所不同。在商业保险条件下，声誉通过弥补患者的信息劣势，加大了对医生欺骗行为的约束；而在社会保险条件下，声誉在提振患者对市场的初始信心的同时，降低了患者因保险依赖而盲目交易的可能性。最后，综合医疗市场的经济效益和社会效益来看，公开信息商业保险和公开信息社会保险是两种相对高效的政策组合。     

Equity,Bonds, Institutional Debt and Economic Growth: Evidence from South Africa

We examine the finance‐growth nexus in South Africa accounting for the role of bond markets, stock markets, and bank and non‐bank financial intermediaries using a vector autoregressive technique. Extant empirical literature has largely accounted for only banks and stock markets, ignoring bond market and non‐bank financial intermediaries. We find that bond market development affects economic growth in South Africa, and no similar effect is observed for the bank and non‐bank financial intermediaries and the stock market. Our finding shows that examination of individual elements of the financial system is important in understanding the unique effect of each on growth. The observation that the bond market rather than stock market, bank and non‐bank institutions promote economic growth in South Africa induces an intriguing question as to what unique roles bond markets play that the intermediaries and equity market are unable to play.     

Do Mutual Fund Investors Care About Auditor Quality?

We study the influence of perceived auditor quality on investment decisions by bond mutual fund investors. Audits of bond mutual funds require significant auditor expertise. Fund managers estimate daily the fair market values of holdings that are often opaque and illiquid. Managers can use their discretion to manipulate their fund's performance results. While it is known that investment flows into funds that report good past performance, little evidence exists about whether investors' confidence in the reliability of fund financial reports is influenced by auditor quality. Using hand‐collected data from SEC filings, we find that the positive association between reported performance and investment flows is stronger for funds with auditors who are industry specialists and are longer‐tenured, as well as for funds that pay higher audit fees. We do not find that auditor office size strengthens the association. We also find that the presence of industry‐specialist auditors, long‐tenured auditors, and higher audit fees lead to additional disclosure in the form of emphasis‐of‐matter. This study contributes to the streams of research investigating perceived audit quality, fund investment decisions, and auditing for financial services.
