“What about liars, cheats, and thieves?”
Jonathan Karpoff, Scott Lee, Gerald Martin
University of Washington, Texas A&M University, American University
… A summary of three related papers on the
consequences and causes of financial
misrepresentation
Question #1: What are the consequences at the firm level?
Paper title: “The cost to firms of cooking the books”
Question #2: What are the consequences for the individual
perpetrators?
Paper title: “The consequences to managers for financial
misrepresentation”
Question #3: What motivates the decision to misrepresent
financial statements?
Paper title: “The determinants of managerial decisions to cook the
books”
The invisible hand
“[Each person] generally, indeed, neither intends to promote the
public interest, nor knows how much he is promoting it … by
directing [his] industry in such a manner as its produce may be of
the greatest value, he intends only his own gain, and he is in this,
as in many other cases, led by an invisible hand to promote an
end which was no part of his intention… By pursuing his own
interest he frequently promotes that of the society more effectually
than when he really intends to promote it.”
– Adam Smith
(IV.ii.6-9, page 456 of the 1776 Glasgow Edition of Smith’s works; vol. IV, ch. 2, p. 477 of 1776 U. of
Chicago Edition.)
Not always?
When does the
pursuit of selfinterest not
promote society’s
interest?
What about liars, cheats, and thieves?
John Rigas, Founder and CEO of Adelphia
Communications. He took home the popcorn.
Dennis Kozlowski, CEO of Tyco
International, Ltd.
– “One of theTop 25 Managers of
the Year” (Business Week
magazine in 2001)
– Now Prisoner 05A4820, in jail
Kenneth Lay, former CEO of Enron Corp.
- Convicted of fraud, false statements
(died, July 5, 2006, before sentencing)
Cheating, and its effects, have become important
concerns in financial markets
“In many countries, expropriation of minority shareholders and creditors
by the controlling shareholders is extensive.”
La Porta, Lopez-de-Silanes, Shleifer, and Vishny (JFE 2000, p.4)
“…[T]he nexus between the accounting firms and the corporations, and
the aggressive attitudes of CFOs and CEOs, has created a pattern of
deception; that has created a situation which has eroded public
confidence in the sanctity of the numbers which is the basis of our
markets today.”
... Arthur Levitt, SEC Chairman 1993-2001, quoted in
http://www.pbs.org/wgbh/pages/frontline/shows/regulation/lessons/
What to do?
“A more activist SEC is what’s needed.”
– The Christian Science Monitor
La Porta et al. (JF 2006) - public enforcement does not work
Jackson and Roe (wp 2007) - public enforcement does work
“It’s time to stop coddling white-collar crooks. Send them
to jail ... Enough is enough: They lie, they cheat, they steal
and they’ve been getting away with it for too long.”
– Fortune magazine
What else can we do?
“The first thing we do, let's kill all the lawyers.”
– William Shakespeare, in Henry VI
“…[L]et's kill all the accountants.”
– New York Daily News
The economic problem
Fraudulent, deceptive, and opportunistic behavior creates a
lemons problem
Information and contracts are costly
Contracts are incomplete
Contracts are costly to enforce
Buyers will demand a discount for the expected amount of
cheating by sellers
The economic problem, continued
All sellers know better than their counterparties whether
they are trustworthy
At “average” terms, only sellers with less-than-average
trustworthiness will engage in trade
Buyers know this, and demand even higher “cheating
discounts”
The market breaks down
What keeps it all together?
Why isn’t fraud, self-dealing, and opportunistic cheating the norm in most
transactions?
Agency theory and internal governance
External discipline and the market for control
International law and finance
Business misconduct, markets, and reputation
The focus
of these
slides
Examine the exceptional transactions, where someone acts
opportunistically
What can we learn about most normal transactions – in which no one gets
cheated or ripped off?
Concern about business misconduct drives
business school curriculae
Ethics teaching is big business
AACSB accreditation requires ethics courses
“Beyond Grey Pinstripes” – A World Resources Institute annual award for
teaching ethics (and sustainability)
“Teaching the Moral Leader” – well-publicized HBS course
Finance scholars have little influence in these areas
Have abandoned the topic – both the budgets and the intellectual
leadership – to non-economics based disciplines
But, we have a lot to say as a positive science
Question #1:
What are the consequences at the firm level?
Data: All (788) SEC and DOJ enforcement actions for financial
misrepresentation initiated from 1978 through September 30, 2006 for:
Books and records violations (15 USC § 78m(b)(2)(A))
Internal controls violations (15 USC § 78m(b)(2)(B))
Data sources:
Lexis-Nexis database
SEC website (all public releases since September 19, 1995)
DOJ staff (direct communications)

to firms
Large losses in share values (~ 40%)
Most of the loss is due to lost reputation, i.e., the value of higher
financing costs and lower net revenues
Consistent with prior law and economics literature on the impact of
cheating on operations
For each dollar that firm value was inflated due to the inflated earnings
and assets…
The firm loses this dollar…
Plus an additional $3.08
$0.36 due to legal costs and settlements
$2.71 due to lost reputation

Takeaways regarding culpable individuals
When misrepresentation is exposed, the perpetrators experience
significant costs:
Job loss (91% of culpable execs)
Losses through shareholdings
SEC fines (average $14.4 million)
Class action/derivative lawsuit awards
Debarment (42% of all culpable execs)
Criminal charges (26% of all culpable execs)
Jail time (average sentence = 5.7 yrs)
Internal governance plays an important role
The sky’s not falling, i.e., “They lie, they cheat, they steal, and they’ve
been getting away with it for too long” is wrong
Question #3: Getting caught is really costly
… So why do they risk it?
Impacts on firms:
40% loss in share value
About 25% of that is
revaluation
Most (66%) of the loss in
value is lost reputation, i.e.,
higher future costs, lower
revenues
Impacts on perpetrators:
91% lose jobs (60% explicitly
are fired)
42% barred from serving as
officers/directors
SEC fine = $14.4 million
Shareholdings decline from
$6m – $39m
26% indicted on criminal
charges
Avg jail time = 5.7 years

A second issue:
Prior results are based on small samples
Median sample size = 101 misrepresentation events
Mean = 176
In actual tests, sample sizes are severely reduced due to data availability
problems
A third issue:
Prior tests have omitted variables issues
Eight types of hypotheses
Like the blind men and the elephant(?)
“…[I]t is not feasible to consider all proposed motivations…”
– Dechow, Sloan, and Sweeney (CAR 1996)
Most focus on one or two types of motive
Efendi et al. (JFE 2007)
Burns-Kedia (JFE 2006)
Agrawal-Chadha (JLE 2005)
So we try a megastudy approach
Group various conjectures, theories into eight types
of motives or constraints
Consider many proxies for each hypothesis
Call them “hypotheses”
Avoid – or at least reduce – omitted variable bias
We have more than 100 proxy variables
Preliminary results use a subset of these proxies
Use large, comprehensive sample
Most prior studies have small samples
Ways to construct a sample
Our approach: All 868 SEC/DOJ enforcement actions from
1978-June 30, 2007 for financial misrepresention
Securities class action (10b-5) lawsuits (e.g., Gande-Lewis,
JFQA 2007; Fich-Shivdasani JFE 2007)
46% of our sample events have corresponding 10b-5 lawsuits
Accounting and auditing enforcement release (AAER)
15 U.S.C. §§ 78m(b)(2)(A) - requires accurate books and records
15 U.S.C. §§ 78m(b)(2)(B) - requires internal controls
AAER is a secondary designation assigned when the enforcement
release names an accountant or auditor
Created in 1982
May not have anything to do with financial misrepresentation
GAO (2002, 2003) restatement database
Currently popular, it’s easy
Universe of financial
misrepresentations
Our sample
• Type I error (miss events in which
misrepresentation occurred) may be high
• Type II error (events include innocent firms or
individuals) is essentially zero
AAER samples
• AAERs miss 18% of enforcement actions, and
29% of all Administrative and Litigation
Releases - so Type I error is higher
• AAERS include many instances in which there
is no financial misrepresentation (e.g., Boston
Scientific – Securities Exchange Act Release
34-43183, also assigned AAER-1295) - so Type
II error is non-trivial.
GAO restatement sample
• 1997–June 2002 (total = 919)
• Attempted to screen for fraud, but SEC now says that
over 50% are not misrepresentations or violations
(implying that Type I and Type II error rates are very
large)
• Hand-collected restatement database in PalmroseScholz (e.g., CAR 2004) does not have these problems
Other data issues
What is the event we wish to examine?
Called 13(b)
(of the SEC
Act of 1934)
violations
We focus on SEC/DOJ actions for financial misrepresentation
Others (e.g., Dechow et al. 1996) look at 13(a) “disclosure” violations
15 U.S.C. §§ 78m(b)(2)(A) - requires accurate books and records
15 U.S.C. §§ 78m(b)(2)(B) - requires internal controls
… Failure to report (e.g., 10-Qs and 10-Ks), failure to disclose information that
should be disclosed, inaccurate info other than in financial statements
(inaccuracies in financial statements trigger violations in bullet item above)
Example #1: Changing from LIFO to FIFO and not disclosing the gain
Example #2: Filing a 10-Q late
Is it “fraud?”
Most researchers say they examine “fraud”
But 25% of all enforcement actions do not include fraud charges

Univariate results - summary
Many things are correlated with the incidence of financial
misrepresentation when viewed in isolation.
But all univariate comparisons suffer from omitted variables
(and possibly problems of simultaneity and endogeneity)
Question: Which hypotheses (stories) are most important?
And which proxies should be used in empirical tests?
Use of multiple proxies causes attenuation bias
Our current approach – 4 types of tests

Ongoing steps in this project
Data reduction techniques to consider more of the 100+ proxies in
our dataset
Other empirical methods issues
Unconditional vs. conditional factor analysis
Factor rotation
Uneven data limitations (e.g., use all available data for each factor?)
Multiple factors/eigenvalue cut offs
Datamine for “best” factors, then use these in empirical tests?
Alternative empirical methods (e.g., the binomial test in my paper with
Boone, Field, and Raheja)?
Compare violation firm-years to non-violation firm-years for same
firms (or used fixed firm effects)?
Be more explicit about using both factor loadings and factor
coefficients in drawing inferences?
