Management Ownership and Audit Firm Size*

The finance literature identifies two agency problems between managers and outside shareholders. First, there is a divergence‐of‐interests problem as management ownership falls. Second, there is an offsetting entrenchment problem when management ownership increases within intermediate regions of ownership. Agency problems are mitigated through contracting, but contracts are often based on accounting numbers prepared by management. Because accounting numbers must be reliable for contracts to be enforced, agency theory predicts a demand for higher‐quality auditors when agency problems are more severe. However, extant studies find no significant or robust relation between management ownership and audit firm size. In contrast to extant research, this study samples unlisted companies rather than listed companies for two reasons. First, the monitoring value of auditing may be higher in unlisted companies because they are less vulnerable to takeover and they are required to disclose much less nonaccounting information to shareholders. Second, unlisted companies have greater variation in management ownership, which permits more powerful tests of the demand for auditing as ownership varies between 0 percent and 100 percent. Consistent with a divergence‐of‐interests effect, the association between management ownership and audit firm size is found to be significantly negative within low and high regions of management ownership. The association is flatter and slightly positive within intermediate regions of management ownership, suggesting the existence of an opposite entrenchment effect. The negative association and the nonlinearity is consistent with the finance literature and with the predictions of agency theory.     

政治关联、事务所规模与审计质量

本文以我国A股上市公司为样本,探讨政治关联、事务所规模与审计质量的关系。研究发现,事务所规模与其审计质量正相关,即规模更大的事务所具有较高的审计质量;政治关联作为我国资本市场上市公司的普遍现象对审计行为具有显著负面影响,有政治关联的上市公司更倾向于选择小规模(非"十大")事务所,无政治关联的上市公司则更倾向于选择大所("十大");具有政治关联的上市公司获得"非标"审计意见的概率低于无政治关联上市公司。

Learning by Doing and Audit Quality*

In this study, we present a nonstrategic, dynamic Bayesian model in which auditors' learning on the job and their choice of professional services jointly affect audit quality. While performing audits over time, auditors accumulate client‐specific knowledge so that their posterior beliefs about clients are updated and become more precise (that is, precision is our surrogate for audit quality) — what we call the learning effect. In addition, auditors can enrich their knowledge accumulation by performing nonaudit services (NAS) that, in fact, may influence clients' managerial decisions — what we call the business advisory effect. This advisory effect permits auditors to anticipate and to learn about changes in clients' business models, which in turn improves their advisory capacity. These dual “learning” and “advisory” effects are interdependent and mutually reinforcing. The advisory effect of NAS may increase or reduce auditors' engagement risk. We show that large professional fees can induce auditors to provide NAS that increase engagement risk and diminish audit quality. However, when NAS reduce engagement risk and increase audit quality, auditors may provide NAS without charging clients. The feature that distinguishes our study — the interdependence between the learning and advisory effects — provides new insight into the trade‐off between audit fees and audit quality. Consequently, our analysis helps explain why the scope of the audit has evolved over time and why the boundaries between audit and NAS are constantly shifting. A recent example of such a shift is that the Sarbanes‐Oxley Act adds control attestation to audits for public companies traded in U.S. markets.     

The Significance of Audit Decision Aids and Precase Jurists' Attitudes on Perceptions of Audit Firm Culpability and Liability*

Abstract. During the past decade, public accounting firms have found themselves targets of litigation. The legal costs associated with the “expectations gap” have been observed to be nontrivial. Among the responses made by some firms in the profession is the increased use of auditor decision aids in an effort to improve auditor adherence to a “standard” that these firms believe they can defend in court. However, once implemented, these “standards,” if not adhered to, may have profound legal ramifications. This paper reports on a behavioral study of these issues. The subjects were 82 U.S. general jurisdiction judges. Findings indicate that the jurists did rely on internal firm guidance when evaluating injured-party claims. Résumé. Depuis une dizaine d'années, les cabinets d'experts-comptables ont été la cible de poursuites en justice. Les observations effectuées démontrent que les frais juridiques associés au « déficit par rapport aux attentes » sont appréciables. Certains cabinets de la profession réagissent, entre autres, en recourant davantage aux aides à la décision conçues pour les vérificateurs, de façon à favoriser chez leurs employés le respect de « normes » que ces cabinets estiment pouvoir défendre devant les tribunaux. Or, une fois établies, ces « normes ?, si elles ne sont pas respectées, peuvent avoir de sérieuses conséquences juridiques. Les auteurs rendent compte d'une étude de comportement relative à ces questions. Dans le cadre de cette étude, 82 juges américains de compétence générale ont été interrogés. Les résultats de l'étude indiquent que les juristes se sont appuyés sur les directives internes du cabinet dans l'évaluation des griefs des parties lésées.     

Audit Firm Tenure,Bank Complexity,and Financial Reporting Quality

Theory from organizations and economics research posits that in an inter‐organizational relationship, both parties invest in relationship‐specific knowledge, which in turn facilitates the effectiveness of the relationship while strengthening the attachment between the parties. In complex settings where there are more opportunities for knowledge creation, the investments will be larger and the attachment stronger. Because banks are complex institutions that present unique challenges to auditors, we suggest that effective audits critically depend on the accumulation of significant investments in client‐specific expertise through a long association with the client. We find a positive association between audit firm tenure and financial reporting quality, and this association is particularly strong in banks that are more complex. Also, contrary to recent research we find that benefits of audit firm tenure for complex banks accrue even for long tenure and are not limited to medium tenure. Our findings largely support the notion that a long relationship with the client reflects the underlying demand for expertise, which is critical for high‐quality audits of complex organizations. Imposing short‐term limits on audit firms would adversely affect the investments in client‐specific expertise especially in the cases where this expertise is needed the most. Our findings do not support calls for mandatory audit firm rotation for large complex institutions.     

Tests of a Deferred Tax Explanation of the Negative Association between the LIFO Reserve and Firm Value*

Guenther and Trombley (1994) and Jennings, Simko, and Thompson (1996) document a negative association between a firm's last-in, first-out (LIFO) reserve and the market value of its equity. In this paper, we test a deferred tax explanation of this negative association. Specifically, we argue that investors, conditional on adjusting inventory to as-if first-in, first-out (FIFO), estimate a firm's future LIFO liquidation tax burden as its LIFO reserve multiplied by the appropriate corporate tax rate and include this tax-adjusted LIFO reserve in the valuation of a LIFO firm's net assets. On the basis of this argument, the tax-adjusted LIFO reserve is in effect an estimate of an off-balance-sheet deferred tax liability and, as a result, we predict a negative association between the tax-adjusted LIFO reserve and market value of equity. We test our deferred tax explanation by estimating a valuation model in which a firm's market value of equity is expressed as a function of the firm's assets, liabilities, deferred tax liability, and tax-adjusted LIFO reserve; the model is estimated separately in years preceding and following the reduction of tax rates mandated by the US Tax Reform Act of 1986. Test results provide strong support for the deferred tax explanation of the negative association between a firm's LIFO reserve and the market value of its equity.     

The Effect of Audit Quality on Earnings Management*

This study examines the relation between audit quality and earnings management. Consistent with prior research, we treat audit quality as a dichotomous variable and assume that Big Six auditors are of higher quality than non-Big Six auditors. Earnings management is captured by discretionary accruals that are estimated using a cross-sectional version of the Jones 1991 model. Prior literature suggests that auditors are more likely to object to management's accounting choices that increase earnings (as opposed to decrease earnings) and that auditors are more likely to be sued when they are associated with financial statements that overstate earnings (as compared to understate earnings). Therefore, we hypothesize that clients of non-Big Six auditors report discretionary accruals that increase income relatively more than the discretionary accruals reported by clients of Big Six auditors. This hypothesis is supported by evidence from a sample of 10,379 Big Six and 2,179 non-Big Six firm years. Specifically, clients of non-Big Six auditors report discretionary accruals that are, on average, 1.5-2.1 percent of total assets higher than the discretionary accruals reported by clients of Big Six auditors. Also, consistent with earnings management, we find that the mean and median of the absolute value of discretionary accruals are greater for firms with non-Big Six auditors. This result also indicates that lower audit quality is associated with more “accounting flexibility”.     

Auditors' Responses to Workload Imbalance and the Impact on Audit Quality*

Using detailed data for fieldwork hours and audit hours by rank from audit engagements in Korea, we examine whether audits conducted under workload imbalance, proxied by busy‐season audits, impair audit quality, and how auditors adjust staff assignments for busy‐season audits. We generally find that busy‐season audits are associated with lower audit quality, and that audit firms reduce the involvement of senior auditors during busy‐season audits. In addition, the greater the involvement of senior auditors and junior auditors, the lesser the deterioration in audit quality. Finally, although there is no increase in interim audits in response to workload imbalance during busy seasons, increasing interim audits can mitigate the negative impact of busy‐season audits on audit quality. Our results are relevant to auditors and regulators, who have expressed concerns about the adverse effects of workload imbalance on audit quality.     

A Note on the Relation between Frames,Perceptions, and Taxpayer Behavior*

In this study, we incorporate taxpayers' threat /opportunity perceptions into our analysis of taxpayer behavior in order to refine and extend our understanding of the internal cognitive forces that shape taxpayer behavior. Decision‐making frames (that is, the gain and loss domains from the prospect theory value function) and individual perceptions (that is, perceptions of decision alternatives as being threats or opportunities) are both likely to influence behavior, yet prior research has generally ignored the behavioral effects of individual perceptions. The results of our experiment reveal that taxpayers who are due a tax refund (owe additional taxes) prior to considering a judgemental tax deduction tend to perceive the conservative (aggressive) tax deduction to be more of an opportunity/less of a threat. In turn, we find that taxpayer frames have a direct effect on taxpayer behavior and an indirect effect on behavior through their effect on taxpayers' threat/opportunity perceptions. Perhaps the most important message of this study is that researchers can advance our understanding of the internal cognitive processes that shape taxpayer behavior by incorporating taxpayer perceptions into their research designs.     

Expertise and Its Relation to Audit Decision Quality*

Abstract. This research study examines the effect of expertise on the quality of audit decision making in an audit planning context. Unlike previous studies, expertise is measured in terms of domain-specific knowledge. The quality of audit decision making is evaluated with three measures: consistency with professional standards, consistency with the firm's standards, and consensus among auditors. In general, findings indicate that the quality of audit decision making, as defined in this study, is better among experts than among novices. More specifically, it appears that both experts and novices possess some minimum level of knowledge to be consistent with professional standards. Second, experts are more consistent with firms' standards for both reliance and substantive decisions, indicating that expert auditors may have finer knowledge than novices. Finally, the experts' consensus level is higher than the novices' consensus level for standard auditing situations although for less standard situations, the consensus level is lower for experts.     

Audit‐Firm Tenure and the Quality of Financial Reports*

This study examines whether the length of the relationship between a company and an audit firm (audit‐firm tenure) is associated with financial‐reporting quality. Using two proxies for financial‐reporting quality and a sample of Big 6 clients matched on industry and size, we find that relative to medium audit‐firm tenures of four to eight years, short audit‐firm tenures of two to three years are associated with lower‐quality financial reports. In contrast, we find no evidence of reduced financial‐reporting quality for longer audit‐firm tenures of nine or more years. Overall, our results provide empirical evidence pertinent to the recurring debate regarding mandatory audit‐firm rotation — a debate that has, to date, relied on anecdotal evidence and isolated cases.     

The Riskiness of Large Audit Firm Client Portfolios and Changes in Audit Liability Regimes: Evidence from the U.S. Audit Market*

We investigate whether the financial riskiness of large U.S. audit firm clienteles varied with the changing audit litigation liability environment during the period 1975‐99. Partitioning the period of study into four distinct periods (a benchmark period (1975‐84), a period of increasing concerns about litigation liability (1985‐89), a period of lobbying for reform (1990‐94), and a post‐relief period (1995‐99)), we find some evidence of risk decreases during 1985‐89, strong evidence of risk decreases during 1990‐94, and strong evidence of risk increases during 1995‐99. However, we also find that over the period of our study, a time during which Big 6 market shares grew appreciably, the proportion of litigious‐industry clients in Big 6 client portfolios grew at about the same rate as the proportion of such clients in the population. Moreover, the Big 6 share of the financially riskiest clients in the economy did not grow as fast as the overall Big 6 market share. In sum, although our evidence is consistent with the hypothesis that the riskiness of Big 6 client portfolios responded to changes in the audit litigation liability environment, we find no systematic evidence of a "race to the bottom" or "bottom fishing" by these firms in a bid to increase their market shares.     

城市规模分布的齐普夫法则评述

在区域经济学关于城市系统中城市规模分布问题研究的文献中,排序—规模原则占据相当的数量,而学者们所津津乐道的则是所谓的城市规模分布的齐普夫法则。分析表明,齐普夫法则只是描述城市规模分布的一个简单的统计关系,一个可供直接的经验检验的假说命题。迄今为止的有关经验研究,只是部分地支持了齐普夫法则。齐普夫法则及其经验研究的最大弱点,在于缺乏一个经济理论基础。     

Legal Penalties and Audit Quality: An Experimental Investigation*

The purpose of this paper is to investigate the impact of legal penalties on audit quality under different legal regimes. We investigate whether audit quality is affected differentially due to the complexity inherent in legal regimes and the frequency of imposing legal penalties. Economic theory predicts that players adopt equilibrium strategies that reflect the expectation that a penalty will be incurred, but the actual occurrences of penalties, if consistent with this expectation, should not prompt an individual to modify his or her strategy. However, learning theory suggests that players' choices will be repeated in the future based on outcomes. We found that penalties triggered both increases and decreases in effort, and seemed to introduce a “shock” that increased the variability of effort. We also observed a “funnel” effect — that is. greater changes in effort closer to the imposition of penalties, and smaller changes as more periods go by without a penalty.     

Audit Committees,Boards, and the Quality of Reported Earnings*

I use data on 252 U.S. firms between 1994 and 2000 to study the relationship between audit committees and boards of directors with financial reporting quality. I initially document several changes in committee and board profile during the sample period. Results from logistic regressions suggest that measures of audit committee and board structure are related to earnings quality in a manner that is generally consistent with the predictions of agency theory. This study contributes to extant knowledge by employing different earnings quality measures from prior studies, and by expanding the range of audit committee attributes deemed important in determining audit committee performance.     

A Note on the Interdependence between Hypothesis Generation and Information Search in Conducting Analytical Procedures*

This study examines the linkage among the initial hypothesis set, the information search, and decision performance in performing analytical procedures. We manipulated the quality of the initial hypothesis set and the quality of the information search to investigate the extent to which deficiencies (or benefits) in either process can be remedied (or negated) by the other phase. The hypothesis set manipulation entailed inheriting a correct hypothesis set, inheriting an incorrect hypothesis set, or generating a hypothesis set. The information search was manipulated by providing a balanced evidence set to auditors (i.e., evidence on a range of likely causes including the actual cause ‐ analogous to a standard audit program) or asking them to conduct their own search. One hundred and two auditors participated in the study. The results show that auditors who inherit a correct hypothesis set and receive balanced evidence performed better than those who inherit a correct hypothesis set and did their own search, as well as those who inherited an incorrect hypothesis set and were provided a balanced evidence set. The former performance difference arose because auditors who conducted their own search were found to do repeated testing of non‐errors and truncated their search. This suggests that having a correct hypothesis set does not ensure that a balanced testing strategy is employed, which, in turn, diminishes part of the presumed benefits of a correct hypothesis set. The latter performance difference was attributable to auditors' failure to generate new hypotheses when they received evidence about a hypothesis that was not in the current hypothesis set. This demonstrates that balanced evidence does not fully compensate for having an initial incorrect hypothesis set. These findings suggest the need for firm training and/or decision aids to facilitate both a balanced information search and an iterative hypothesis generation process.
