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”.     

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.

本文经过实证发现,收入和利润同时增长的公司具有(1)较好的盈利质量和(2)比只有利润增长的公司更大的利润反应系数(Earnings Response Coefficients,ERC).从盈利质量来看,收入上升拉动利润的公司的收益更具有持久性,更不易受到盈余管理的干扰,以及在未来具有更佳的业绩.从反应系数来看,这类公司的利润反应系数较大,而账面净资产反应系数则较小,这和Ohlson(1995)的结论相一致.     

The Effect of Corporate Merger Transactions on the Information Content of Earnings Announcements*

Abstract. This study develops and tests the proposition that corporate merger transactions give rise to changes in the association between firm accounting earnings and security returns. A model of the effect of merger transactions on stock price responses to information releases suggests that the earnings response coefficient of a postmerger entity is a weighted average of the earnings response coefficients of the combining firms, with the weights depending on relative earnings variability of the combining firms. Empirical results, based on a sample of 90 mergers completed over a 12-year period, are consistent with the model. Résumé. L'auteur élabore et vérifie une proposition selon laquelle les opérations de fusion donnent lieu à des changements dans la relation entre les bénéfices comptables de l'entreprise et le rendement de ses titres. Selon le modèle de l'incidence des opérations de fusion sur la réaction du cours des valeurs mobilières à la communication d'information, le coefficient de réaction des bénéfices d'une entité résultant d'une fusion est la moyenne pondérée des coefficients de réaction des bénéfices des entreprises qui fusionnent, les pondérations dépendant de la variabilité relative des bénéfices des entreprises constituantes. Les résultats empiriques, fondés sur un échantillon de 90 fusions s'échelonnant sur une période de plus de 12 ans, confirment la validité du modèle.     

Pricing of Initial Audit Engagements by Large and Small Audit Firms*

We investigate the extent to which auditors of U.S. companies reduce fees on initial audit engagements (“fee discounting”). We hypothesize that rivalries among sellers, in terms of client turnover and price competition, are more intense among small audit firms. The data support this hypothesis. New clients account for 34 percent of all clients for small audit firms, but only 9 percent of all clients for large audit firms. We theorize that differences in client turnover rates between large and small audit firms can be explained by the market structure of the audit industry, which consists of an oligopolistic segment dominated by a few large audit firms and an atomistic segment composed of many small audit firms. We further hypothesize and confirm that fee discounting is more extensive in the atomistic sector, and our results confirm this hypothesis. Our analysis of audit fee changes indicates that clients who switch auditors within the atomistic sector receive on average a discount of 24 percent over the prior auditor's fee. However, clients who switch auditors within the oligopolistic sector receive on average a discount of only 4 percent. Given that price competition is known to be less intense in oligopolistic markets than in atomistic markets, we believe that market structure theory can explain why fee discounting is lower when larger audit firms compete for clients.     

Earnings Attribution and Information Transfers

Managers frequently attribute the news in their earnings forecasts to various economic events. Using textual analysis, we identify the economic factors underlying earnings news from press releases. We document a wide range of industry‐wide shocks and firm‐specific actions to which the earnings news in management forecasts is attributed. As expected, earnings attributions significantly affect peer firms’ price reactions to the earnings news. Specifically, earnings news attributed to industry‐wide trends or firm structural changes leads to positive information transfers but earnings news attributed to firm competitive moves triggers negative information transfers. Information transfers are much stronger when each economic factor is mentioned the first time in a given industry‐year. Further analysis reveals that the strength of information transfers varies with firm‐level rivalry within the industry (i.e., similar business strategies, market position, and level of competition).

Production Efficiency and the Pricing of Audit Services*

In this paper, we examine the relative efficiency of audit production by one of the then Big 6 public accounting firms for a sample of 247 geographically dispersed audits of U.S. companies performed in 1989. To test the relative efficiency of audit production, we use both stochastic frontier estimation (SFE) and data envelopment analysis (DEA). A feature of our research is that we also test whether any apparent inefficiencies in production, identified using SFE and DEA, are correlated with audit pricing. That is, do apparent inefficiencies cause the public accounting firm to reduce its unit price (billing rate) per hour of labor utilized on an engagement? With respect to results, we do not find any evidence of relative (within‐sample) inefficiencies in the use of partner, manager, senior, or staff labor hours using SFE. This suggests that the SFE model may not be sufficiently powerful to detect inefficiencies, even with our reasonably large sample size. However, we do find apparent inefficiencies using the DEA model. Audits range from about 74 percent to 100 percent relative efficiency in production, while the average audit is produced at about an 88 percent efficiency level, relative to the most efficient audits in the sample. Moreover, the inefficiencies identified using DEA are correlated with the firm's realization rate. That is, average billing rates per hour fall as the amount of inefficiency increases. Our results suggest that there are moderate inefficiencies in the production of many of the subject public accounting firm's audits, and that such inefficiencies are economically costly to the firm.     

Corporate Governance and the Information Content of Earnings Announcements: A Cross‐Country Analysis

Using firm‐level data from 23 developed markets, we document a positive association between overall firm‐level governance quality and the informativeness of earnings announcements measured by abnormal stock return variance. This finding is robust after controlling for the potential endogeneity of firm‐level corporate governance. Further analyses reveal that firms with strong governance show little evidence of earnings management, appoint Big 4 auditing firms, and attract analyst following, implying a positive link between strong corporate governance and the information quality of earnings announcements. Finally, there is some evidence that the relation between firm‐level governance and market reactions around the announcements exists only in countries characterized by a transparent information environment and strong legal investor protection.     

A Comparison of Dividend,Cash Flow,and Earnings Approaches to Equity Valuation*

Standard formulas for valuing the equity of going concerns require forecasting payoffs to infinity but practical analysis requires that payoffs be forecasted over finite horizons. This truncation inevitably involves often-troublesome terminal value calculations. This paper contrasts dividend discount techniques, discounted cash flow analysis, and techniques based on accrual earnings when each is applied with finite-horizon forecasts. Valuations based on average ex post payoffs over various horizons, with and without terminal value calculations, are compared with ex ante market prices to discover the error introduced by each technique in truncating the horizon. Valuation errors are lower using accrual earnings techniques rather than cash flow and dividend discounting techniques. The accounting features that make a given technique less than ideal for finite horizon analysis are also detailed. Conditions where a given technique requires particularly long forecasting horizons are identified and the performance of the alternative techniques under those conditions is examined.     

Determinants of the Time Series of Earnings and Implications for Earnings Quality*

This paper examines whether differences in accrual accounting methods across balance sheet accounts influence the time‐series process of earnings. We define earnings quality as the responsiveness of earnings to shifts in permanent earnings and predict that responsiveness will increase in a firm's use of variable rate debt, where accruals move directly with shifts in interest rates. We also predict that responsiveness will decrease in a firm's investment in property plant and equipment because depreciation is largely predetermined and does not respond to shifts in opportunity costs. </P><P>To test these hypotheses, we regress earnings on lagged earnings and a proxy for permanent earnings (that is, the implied dividend annuity in lagged equity value). Within the context of an adjustment cost model, this regression captures the responsiveness of earnings by the coefficient on lagged price and by one minus the coefficient on lagged earnings. Consistent with this framework, we find the unconstrained estimated coefficients on these two variables to be negatively correlated. Furthermore, consistent with our hypotheses, we find that the coefficient on lagged earnings (lagged price) is positively (negatively) associated with the relative magnitude and life of fixed assets on the balance sheet and negatively (positively) associated with the relative magnitude of variable rate debt on the balance sheet.</P>     

预算软约束、企业财务风险与审计定价

本文具体考察在上市公司存在预算软约束的情况下,我国的会计师事务所在审计定价时如何考虑上市公司的财务风险.研究结果表明:①事务所的审计收费与上市公司的负债比率之间呈显著的正相关关系;②在国有上市公司中,预算软约束程度的增加降低了公司的财务风险,因此审计收费与公司负债比率之间的正相关关系有所减弱;③在金融发展水平比较高的地区,预算软约束程度的减轻提高了公司的财务风险,因此审计收费与公司负债比率之间的正相关关系有所增强.这一研究结果说明,我国的会计师事务所在审计定价时不仅考虑了上市公司的财务风险,而且还会根据公司的预算软约束程度对其财务风险进行相应的调整.     

Understanding Audit Quality: Insights from Audit Professionals and Investors

Projects seeking to define, measure, and evaluate audit quality are on the agendas of auditing standards setters as well as audit firms. The Public Company Accounting Oversight Board (PCAOB) currently provides information regarding audit quality through the release of inspection reports, and the Board intends to establish and report audit quality indicators. To provide additional perspective on audit quality, we obtain auditors' and investors' views, definitions, and indicators of audit quality. We find that investors' definitions of audit quality focus more on inputs to the audit process than do auditors', and that investors view the number of PCAOB deficiencies as an indicator of overall firm quality. We find a consensus that auditor characteristics may be the most important determinants of audit quality, and that restatements may be the most readily available signal of low audit quality. We relate responses to a general audit quality framework, provide support for archival audit research, and identify additional disclosures that participants suggest could signal audit quality. Taken together, we provide evidence regarding the construct of audit quality in the post‐SOX environment, evaluate many of the audit quality indicators proposed by the PCAOB, and suggest avenues for future research.
