data innovation in empirical audit research
Data Innovation in Empirical Audit Research
  • Do what you enjoy, and find the right data for the RQ
  • Innovation through new data
    • Use new data to answer “old” questions better or to answer “new” questions that could not previously be investigated
      • public data – new U.S. audit fee data or internal control reports
        • but risky because of competition
      • private data avoids competition
        • but can be risky because it’s costly and the outcome is unknown
  • Novel use of existing public data
    • Creatively use existing data in new ways
      • link financial statement properties (e.g., abnormal accruals) with auditor characteristics
        • Becker et al. (CAR 1998) & Francis et al. (AJPT 1999)
      • office-level analysis of Big 4 accounting firms
        • Reynolds &Francis (JAE 2000)
audit research i ntersection of practice theory research design choices
Audit Research:Intersection of practice, theory & research design choices
  • Practice drives research questions (RQ)
    • Some examples (next slides)
  • Theory informs/frames RQ
    • Economics, agency & signaling theory, psychology
  • Research design – many choices
    • Modeling, experimental, & archival
  • Inherent limits of RQs answerable by a single approach/method
    • Value of triangulation/complementarity

units of analysis in audit research red denotes prime empirical areas
Units of Analysis in Audit Research(“red” denotes prime empirical areas)
  • Audit testing & evidence-gathering procedures
  • Auditor judgments about testing & evidence
    • Auditors apply/interpret testing procedures
      • As individuals (individual judgments)
      • In teams (group judgments)
  • Accounting firms
    • Auditors work in firms
      • Observable “audit firm” outcomes are audit reports & audited financial statements (and who audits whom)
  • Audit industry and audit markets
    • Audit firms operate & compete in audit markets
  • Regulatory institutions and public policy
    • Auditors, firms and markets are regulated
audit testing procedures requires accounting firms

    • Archival - Do control risk assessments affect other audit tests?
      • Mock and Wright (AJPT 1999), test of the “audit risk model”
    • Experimental - Is the new “business risk” audit approach effective?
      • O’Donnell & Schultz (TAR 2005)

    • Do different “interventions” affect auditor-client negotiation outcomes?
    • Do alternative forms of “review” affect auditor performance?
    • Do “groups” outperform individuals?
      • Audit teams required to “brainstorm” for fraud risk
    • Does the “business risk” model improve auditor judgments?

empirical research on audit quality

Empirical Research on Audit Quality

Audits are relatively cheap, and proven

failures are infrequent.

But this does not necessarily mean audits

are always of high quality.

What do we know about audit quality

from empirical research?

research on audit outcomes

Research on Audit Outcomes

What do know about audit quality from audit report research?

inferring audit quality from audit reports
Inferring Audit Quality from Audit Reports
  • After 1989, only two primary audit reports
    • Standard clean opinion (90%)
    • Modified opinion for going concern (GC) (10%)
  • How do users respond to “modified” reports?
    • Are modified reports perceived to convey “negative” news?
    • If so, then audit reports are informative and auditing has value to users
type 1 2 error rates 1995 2003 compustat population
Type 1 & 2 Error Rates(1995-2003 Compustat Population)
  • Clean opinions (90%), GC (10%), n= 62,094 firm-year observations
      • Overall Error Rate – 9.5%
  • Type 1 Errors (false negatives) – 9% (over-qualifying or auditor conservatism)
      • No bankruptcy within one year, but 9% had GC reports
        • 5,467 GC reports for 785 bankruptcies (7 GC per bankruptcy)
  • Type 2 Errors (false positives) – 55% (under-qualifying)
      • Bankruptcy within one year (785) but no GC 55% of time, i.e., 432 cases over an 8-year period
do modified audit reports matter given type 1 2 errors
Do Modified Audit Reports Matter(given type 1/2 errors?)
  • Informational value is difficult to assess
    • Audit reports issued concurrently with financials
    • Most GC reports are “repeat offenders”
  • Evidence that “surprise” first-time GC reports reduce share prices
      • Dodd et al. (JAE 1984), Loudder et al. (AJPT 1992)
  • Predictive ability of modified audit reports for material loss contingences (lawsuits)
      • Raghundan (CAR 1993)
audit reports and the ipo setting
Audit Reports and the IPO Setting
  • Audit report has potentially more value
    • Greater information uncertainty/asymmetry
  • Weber and Willenborg (JAR 2003)
    • Microcap IPO’s < $10 million
    • 23% have GC reports preceding IPO
    • Pre-IPO audit reports predict delistings and future stock returns
    • But more so for large (Big 4 & national) auditors
who audits whom

Who Audits Whom?

What do we know about auditor differences and audit quality?

differential audit quality research
Differential Audit Quality Research
  • Audit quality cannot be directly observed
    • Except for “proven” audit failures (ex post) which are rare
  • Instead – differential audit quality is inferred
    • Comparing audit outcomes between “classes” of auditors
  • All firms are assumed to meet minimum professional & legal requirements
  • But many different types of firms exist
    • Suggests supply of differential auditing
    • Implies differential demand (clienteles)
audit firm size is bigger better
Audit Firm Size:Is Bigger Better?
  • The big firm/small firm dichotomy
    • Big 8 (now Big 4) firms have brand name reputation and incentives to protect their reputation
      • Simunic and Stein (1987 CGA Monograph)
  • Auditor size proxies for quality due to less fee dependence (DeAngelo, JAE 1981)
    • Client dependence = 1/n (where n=number of clients)
    • Now we can use actual fee dependence
  • Doesn’t mean Big 4 audits are always better
    • It just means that on average they are better
    • Individual audit failures can and do occur
evidence of big 4 audit quality differentiation
Evidence of Big 4 Audit Quality Differentiation
  • Audit pricing
    • Big 4 audit fee premia of 20-50%
      • US, Australia, Hong Kong, UK
    • Implies more quantity and/or better quality auditing
      • Higher fees imply voluntary demand for higher quality audits by some clients
  • Demand for quality
    • Demand for Big 4 audits is increasing in agency costs
      • Francis & Wilson (TAR 1988), DeFond (AJPT 1992)
    • IPOs with larger auditors have less IPO underpricing
      • Beatty (TAR 1989), Willenborg (JAR 1999)
other evidence
Other Evidence
  • Big accounting firms are sued less often
    • Litigation as quality proxy (Palmose, TAR, 1987)
  • Big firms sanctioned less often by regulators
    • Feroz et al. (JAR 1991)
  • Alternative explanation is that big firms are more powerful and have resources to fight
    • But evidence on audit “outcomes” is more consistent with higher quality
    • Let’s turn to that evidence
evidence from audit outcomes
Evidence from Audit Outcomes
  • Audit Reports of Large (Big 4) Auditors
    • More conservative reports (more modifications)
      • Francis & Krishnan (CAR 1999), (APJAE 2003)
    • More informative reports (predictive power)
      • IPO setting, Weber & Willenborg (JAR 2003)
      • More accurate reports in UK, Lennox (ABR 1999)
  • Financial Statements Audited by Big 4 Auditors
    • Smaller abnormal accruals -- less managerial discretion
      • Becker et al. (CAR 1998), Francis et al. (AJPT 1999)
    • Accruals/earnings surprises valued higher in the stock market
      • Teoh & Wong (TAR 1993), Krishnan (AJPT 2003)
conclusions on auditor size
Conclusions on Auditor Size
  • Evidence is supportive of higher Big 4 audit quality
  • But an alternative explanation is endogeneity
    • i.e., “good” companies choose good (Big 4) auditors, in which case selection may explain outcomes, not audit quality
  • Heckman 2-stage approach is trendy
    • But most studies using it support prior findings on audit quality
      • Weber & Willenborg (JAR 2003), Hogan (TAR 1997), Ireland & Lennox (JAAF 2002)
      • Chaney et al. (TAR 2004) is an exception
  • Can we identify good “instruments” in accounting research?
    • Larcker & Rusticus (SSRN WP) are skeptical
  • If there’s reason to think selection exists, an alternative is to control through research design choices
      • e.g., matched pairs, or samples limited to smaller clients
moving beyond the big small dichotomy

Moving Beyond the Big-Small Dichotomy

Differentiation within

the dominant Big 4 group

within big 4 differentiation
Within-Big 4 Differentiation
  • In past, Big 4 viewed as homogenous group
  • B4 (90%) & NB4 (10%) U.S. market shares
    • Low power due to small variance in auditor type
  • May be more variation within Big 4 firms
    • Some plausible within-Big 4 variations:
      • Industry expertise
      • Geographical variation
      • Offices (cross-city differences)
      • Countries (cross-country differences)
industry expertise
Industry Expertise
  • Firms actively promote their industry expertise
  • Industry experts have more experience and appear to make better audit judgments
    • Solomon et al. (JAR 1999); Low (TAR 2004)
  • Auditor clienteles proxy for industry expertise
    • More clients create more opportunities to acquire deep industry knowledge/expertise
  • Industry shares are not evenly distributed
    • Using 2000-2001 U.S. fee data & 2-digit SIC codes
      • #1 firm has 50% of industry fees, #2 firm only 22%
      • Leadership among Big 5 firms for 63 industries
        • AA (14), DT (5), EY (16), KPMG (9), PWC (19)
evidence from audit fees
Evidence from Audit Fees
  • Big 4 industry leaders have higher fees (10-30%) and higher fees imply higher quality audits
  • Financial statement outcomes evidence higher quality audits by Big 4 industry leaders
    • Smaller abnormal accruals (less discretion)
      • Balsam et al. (APJT 2003), Krishnan (AH 2003)
    • Higher valuation of earnings surprises
      • Balsam et al. (AJPT 2003)
    • Less fraudulent reporting (AAERs)
      • Carcello & Nagy (2004 Managerial Auditing Journal)
    • Less IPO underpricing and smaller accruals
      • Elder and Zhou (2003 WP)
what is an accounting firm

What is an Accounting Firm?

What’s the relevant unit of

analysis?

Individual offices, national

practices, or international

operations?

arguments for an office level analysis
Arguments for an Office-Level Analysis
  • Accounting firms are decentralized networks of quasi-independent practice offices
  • Engagement partners in local offices contract and administer audits to clients in the same locale
      • Issue audit reports on office letterhead
        • Francis et al. (ABACUS 1999); Reynolds & Francis (JAE 2000); Ferguson et al. (TAR 2003)
  • Client influence/fee dependence is stronger at the office level
      • Enron < 2% of Andersen fees nationally
      • Over 30% of Houston office fees
first office level study reynolds francis jae 2000
First Office-Level StudyReynolds & Francis (JAE 2000)
  • Auditors are more conservative for larger clients in U.S. practice offices
    • They issue more GC audit reports
    • Clients have smaller abnormal accruals
      • Client size measured “relative” to office clienteles
  • Client size is not significant using national clienteles to measure relative client size
  • Conclusion
    • Office-level data provides better understanding
      • No results using aggregate data; but evidence of auditor conservatism using office-level data
office level reputation for industry expertise
Office-Level Reputation for Industry Expertise
  • Is industry expertise firm-wide (national), office-specific (city), or combination of both?
    • Office-specific arguments
      • Deep expertise is client-specific and cannot be fully captured by firms and distributed across offices
      • Gilson & Mnookin (SLR 1985), law firms
    • Firm-wide arguments
      • Standardized training/audit practices and knowledge sharing is possible across offices
how is national versus city industry leadership priced
How is National Versus City Industry Leadership Priced?
  • 4 possibilities(Francis et al., TAR 2005)
    • Engagements where auditor is both the national and the city-specific industry leader
        • 18% of US sample
    • Engagements where auditor is a national industry leader (alone)
        • 10% of US sample
    • Engagements where auditor is a city-specific industry leaders (alone)
        • 23% of US sample
    • Nonleaders (neither city/national leaders)
        • 49% of US sample
evidence
Evidence
  • Joint national-city #1 has +28% premium
  • City-alone #1 has +10% premium
  • National-alone #1 has no fee premium relative to nonleaders (default group is nonleaders)
  • Implication - audit quality is office-specific
    • Industry premia only when a city leader
      • Either alone or joint national-city leader
    • National market share is driven by city leadership
      • National #1, 86% of fees where city leader
rq does city leadership affect earnings quality
RQ - Does City Leadership Affect Earnings Quality?
  • Follow-up WP to Francis et al. (TAR 2005)
    • Uses same B5 sample from 2000-01 first-time cycle of fee disclosures to measure industry leaders
  • What do we find?
    • Clients of city industry leaders have smaller abnormal accruals, and smaller income-increasing accruals
      • Magnitude is 6-12% of pre-tax earnings
    • Clients of joint national-city leaders are less likely to meet or beat by +1 cent analysts’ forecasts (40%  29%)
    • City-only leaders are also less likely to do so (40%  33%)
    • In both tests results for national leaders (alone) are n.s.
legal systems and differential auditing over time countries
Legal Systems and Differential Auditing(over time/countries)
  • Institutions & legal regimes affect auditor incentives
  • Two research approaches
    • A regime change within a single country (over time)
      • The Private Securities Litigation Reform Act of 1995
        • Lee and Mande (AJPT 2003), Francis & Krishnan (APJAE 2003)
    • Cross-country studies of different legal regimes
      • Seetharaman, Gul and Lyn (JAE 2002)
        • higher audit fees of UK firms cross-listed in US
        • implies higher fees due to increased litigation risk exposure
      • Khurana et al. (TAR 2004)
        • B4 clients have lower COC in US (but not Australia, UK, Canada)
        • Implies US litigation risk drives B4 behavior (not reputations)
rq do b4 incentives vary across legal regimes
RQ – Do B4 incentives vary across legal regimes?
  • Do B4 audits vary across jurisdictions?
  • Three Scenarios
    • Big 4 are uniform around the world
      • Incentives to maintain brand name (standardization)
    • U.S. is an outlier due to extreme liability exposure
      • More lawsuits in US than rest of world combined
    • Big 4 conservatism is increasing in country-level investor protection and auditor litigation risk

Preliminary Results Indicate that Legal Regime Matters
  • Big 4 conservatism is
    • Increasing in investor protection/litigation risk
    • Holds both with/without U.S. observations
    • Implies less discretion to manage earnings
  • Magnitude
    • Abnormal accruals are smaller by around 5% of earnings in common law countries with stronger investor protection
  • Non-Big 4 firms are uniform across countries (and less conservative than Big 4)
    • Less incentive for reputation protection/litigation avoidance behavior (same as within US)
other examples of research on audit quality

Other Examples of Research on Audit Quality

Auditor tenure

Non-audit services (NAS)

Audit committees/corporate

governance

Accounting firm alumni

auditor tenure
Auditor Tenure
  • Tenure and mandatory auditor rotation
    • Long tenure is good because auditors know more about the client (deeper knowledge)
    • Long tenure is bad because of entrenchment and self-serving bias
  • The evidence to date:
      • Audit quality is lower in first 3 years
        • Johnson et al. (CAR 2002)
      • But longer tenure (5+ years) increases audit quality
        • Meyer et al. (TAR 2003)
      • Studies of partner tenure in Australia and Taiwan
        • Office level analysis
nonaudit services nas
Nonaudit Services (NAS)
  • Do NAS impair auditor independence?
    • More fee dependence
    • Inherent conflict of interest
    • SEC attempted to ban NAS in 2000
  • Profession’s defense
    • Increases auditor’s knowledge
    • Clients demand and value NAS
    • Incentives exist to protect reputations for independence
evidence45
Evidence
  • Frankel, Johnson & Nelson (TAR 2002)
    • Compelling set of results against NAS
    • Firms with higher NAS are associated with more earnings management:
      • Larger abnormal accruals (more discretion)
      • More likely to meet analysts’ earnings targets
  • But also counter-evidence
    • Ashbaugh et al. (TAR 2003), Chung & Kallapur (TAR 2003), Reynolds et al. (AJPT 2004), DeFond et al. (JAR 2003), Larcker & Richardson (JAR 2004)
broader implications
Broader Implications
  • Accounting journals generally don’t publish replications and no-result studies
  • But replications show fragility and sensitivity to design choices
    • e.g., Frankel et al. (TAR 2002) & Ashbaugh et al. (TAR 2003) get different results on main tests, but with slightly different samples/models
audit quality and corporate boards governance
Audit Quality and Corporate Boards/Governance
  • Audit quality is better when strong boards and audit committees exist (independence/outside directors)
    • Auditors are more likely to issue GC reports
        • Carcello and Neal (TAR 2000)
    • Less likely to be replaced following GC report
        • Carcello and Neal (TAR 2003)
    • Auditors are more likely to detect fraud
        • Dechow et al. (CAR 1995)
    • Accruals are smaller (less earnings management)
        • Klein (JAE 2002), Bedard et al. (AJPT 2004)
    • Auditors have higher audit fees and are less likely to perform non-audit services
        • Abbot et al. (SSRN 2001), Abbott et al. (AJPT 2003)
accounting firm alumni and auditor independence
Accounting Firm Alumni and Auditor Independence
  • Outplacement to clients impairs audit quality
    • Clients know the auditor’s methods too well
    • Auditor is cozy with former colleagues
  • Lennox (JAE 2005)
    • Outplacement is less than perceived (10%)
    • But GC reports are less frequent than predicted (suggests client leniency)
  • Menon & Williams (TAR 2004)
    • Firms with alumni have larger abnormal accruals
policy making

Policy Making

What’s the role of

academic auditing research

on audit quality?

the u s experience
The U.S. Experience
  • Academic research has little influence on regulation and policy-making
  • Two recent examples that ignored research
    • SEC’s proposed ban on NAS in 2000
      • Arthur Levitt was convinced a ban was needed
    • Quick adoption of Sarbanes-Oxley (SOX) in 2002
      • Political cover following Enron/Worldcom scandals
why so little impact
Why so little impact?
  • Partly our fault
    • We rarely frame our research around normative regulatory issues or ‘sell’ its policy importance
    • We may not appear to be neutral
      • There’s often an explicit anti-regulatory posture
      • And we may (rightly) be viewed as apologists for the accounting profession
  • Partly policy-makers’ fault
    • No tradition of basing policy on research
    • Policy-making is inherently political (not scientific)
    • Overtures by the PCAOB are encouraging
some important unanswered questions
Some ImportantUnanswered Questions
  • Does the U.S. evidence generalize to countries with different legal and regulatory institutions?
  • How much auditing is optimal?
    • Audits are not very costly and proven failure rate is low
    • Is ‘more’ auditing desirable, or cost-effective, e.g., SOX?
  • Is differential audit quality a good thing?
    • If Big 4 or industry leaders are better, should they be mandated?
    • Or should there be choice?
  • Is government regulation (SEC/PCAOB) better than self-regulation with government oversight?
and finally
And Finally
  • What level of “legal risk” achieves optimal audit quality?
      • U.S. is an outlier in legal-liability risk, although we observe B4 conservatism in other common law countries
      • The risk of “audit firm failure” is real in the U.S. but nearlyimpossible in rest of world
  • Does “extreme” legal risk create the best incentive?
      • It didn’t prevent the Arthur Andersen collapse or frauds such as Worldcom, Adelphia, and HealthSouth
  • Another U.S. audit firm failure could end private-sector auditing around the world (global Big 4)
      • All Big 4 firms have serious legal problems
      • Is a “Big n <= 3” viable for private-sector auditing
