THE CONTRIBUTIONS OF ACCOUNTING RESEARCH:
ACHIEVEMENTS AND THINGS TO DO

At a Glance 2
Accounting Research had
considerable success in the regulatory, managerial and investment areas. Examples:
Fair value accounting
Sarbanes-Oxley consequences
Managerial compensation—“Say on Pay”
Corporate governance
Earnings guidance
Managerial quality
lack of progress, or even serious efforts, to change the accounting model, its framework or practices
Accounting heavy reliance on subjective managerial estimates and projections
Fair Value (FV) Accounting is Not a Myth
3
Major questions: Is FV relevant for share valuations?
For risk assessment? Is it manipulated by management?
Did it enhance the 2007-2008 financial crisis?
Research findings:
Fair values of assets/liabilities, even Level 3, more
relevant to investors than amortized costs.
Fair values are highly informative regarding firm risk and
liquidity—a weak aspect of accounting.
Fair values are sometimes manipulated by managers.
There is no evidence that fair values were “procyclical”—
contributing to the financial crisis.
4
Major questions: given that the Act is very costly, are there
noticeable benefits to it? Particularly to disclosure of
material internal control weaknesses which adversely affect
quality of financial reports
Research findings:
Passage of the Act triggered significantly positive market reaction
of investors.
Firms disclosing material internal control weaknesses experienced
a significant decrease in stock prices.
These decreases were smaller if auditors were of high quality.
Material control weaknesses led financial analysts to reduce
earnings forecasts.
5
Major questions: “Say on Pay” regulation which
started in the U.K. (2002), and enacted recently in the
U.S. (2010) gives shareholders a vote on executive
compensation. Question: Is this a good thing?
Research findings:
The UK and US experience shows that negative SOP vote
targets companies with excessive compensation.
After negative vote, executive compensation is cut
significantly.
No evidence of serious political influence on SOP votes.
“Say on Pay” (SOP) Restricts
Unwarranted Compensation
6
Major questions: The corporate scandals of the early 2000s (Enron, Parmalat, Siemens) focused attention on corporate governance. Questions: Do governance refroms improve corporate performance, reduce fraud, increase reports quality?
Research findings:
The correlation between directors’ independence and corporate performance is weak at best (US data)
Directors’ financial expertise is associated with less fraud and higher quality reports.
No evidence that separating CEO from board chair contributes to performance.
Mixed Evidence on Corporate Governance
Earnings Guidance Benefits Investors
and Firms 7
Major questions: About 1,500 US companies regularly
disclose earnings and sales guidance (forecasts) to
investors. Question: What are the benefits of guidance?
Research findings:
Guidance decreases investors’ disappointment, increases
managers’ credibility, and reduces litigation exposure.
Firms that stop guidance suffer share price decreases.
Firms that stop guidance increase investors uncertainty and
lose analyst following.
Firms often guide when they see an increase in stock
volatility (investor uncertainty).
Managerial Quality Can Be Measured 8
Major questions: The most important asset of most
companies is the quality of their managers. Questions: Can
managerial quality be measure? Does it affect business
performance and ethical conduct?
Research findings:
With several teams of researchers I developed two approaches
to measure quality of managers.
These quality measures are strongly associated with business
performance and stock prices.
Managerial quality measures predict future stock performance.
High quality managers produce more reliable, less manipulated
financial reports.
Summary: Research Contributions 9
Relevance: The above examples clearly show that certain
research findings are relevant to society (regulations),
investors (managerial quality), and managers (guidance).
Accounting reforms: Surprisingly, accounting research has
very little to say about improving the accounting model,
new modes of reporting, accounting for intangibles, etc.
Post Mortem: Researchers don’t even try to explain why
financial information failed to alert investors and the public
to accounting scandals, or the excessive risk taken by
financial institutions before the 2007-2008 crisis.
A lot of things remain to be done.
Accounting Reform: An Example 10
Most financial statement items (accounts receivable, inventory, fixed assets, sales of long term products, pension expense, etc.) are based on managers’ estimates and forecasts; often multiple estimates.
These estimates and the consequent reliability of financial information are increasingly challenged by:
Deregulation, globalization, and fast technological changes, all enhancing business uncertainty, and making accounting forecasts (asset write-offs, options expense) increasingly difficult.
Managers’ manipulation of financial information by misestimates and biased forecasts. They can do it with impunity.
Investors Unable to Assess Impact
and Reliability of Estimates
“GE brings good things to life” (but not to accounting):
“We estimate total long-term contract revenues… We
measure long-term contract revenues by applying our
contract-specific estimated margin rates to incurred
costs. We routinely update our estimates of future
costs for agreements in process…We provide for any
loss that we expect to incur on these agreements when
the loss is probable.” (GE 2010 financial report).
Shouldn’t investors know how much of GE’s total 2010 revenue of
$150 billion is based on estimates?
11
Investors Unable…Continued
Investors are generally unable to determine the impact of estimates on key financial statement items (e.g., how much of earnings is fact, and how much estimate?)
Investors unable to assess reliability of estimates. For most accounting estimates, the ex post realizations are not reported (e.g., the multiple estimates underlying the stock option expense). An invitation to manipulation.
Managers are rarely tracking the quality of their estimates and projections—crucial for improving the estimation procedures. Auditors too are largely uninterested.
12
12
Standard-Setters constantly increase the
prevalence and impact of estimates in
financial reports:
13
assets and goodwill write-offs
fair value
accounting
stock option
expense
environmental
risks (?)

The Result: Constant Increase in
Earnings Uncertainty

Relevance-Challenged Earnings Have
Low Predictive-Ability
I compared the predictive-ability of net earnings with
that of gross profit, cash from operations, and free cash
flows (latter three are less affected by estimates than
net earnings) regarding future values of these series
(out of sample).
Results indicate that net earnings generally perform the
worst of the four measure. It is best only in predicting
next-year’s earnings. It is worst in beyond-one-year
predictions. Cash flows outperforms earnings in
predicting cash flows. Source: Lev, Li and Sougiannis, "The Usefulness of accounting estimates for predicting cash flows
and earnings," Review of Accounting Studies, 2010 15
15
So, What’s To Be Done?
Various suggestions have been made to mitigate
the adverse effects of unreliable estimates on the
usefulness of financial information.
None received serious consideration by accounting
policymakers.
None received serious attention by accounting
researchers.
A sad commentary

Forecasts*

Jim Ohlson’s Gradation of Reliability
The income statement should reflect gradations of reliability.
• Revenues and expenses not subject to estimates (recall GE)
• Items subject to high quality estimates (bad debt expense, warranties expense)
• Items subject to low-reliability estimates (stock options expense, gains/losses from Level 3 fair values)
• Net income
18
Lundholm’s Suggestion for Comparison
of Estimates with Ex-Post Realizations
A routine comparison in financial reports of key estimates with realizations, and managers comments on the deviations.
This will do wonders to improve managers’ ex-ante incentives to provide reliable estimates.

past: A new approach to
improving accounting today,"

Lev-Ryan-Wu’s Proposal for a Required
Revision of Earnings for Major Misestimates*
Research has documented that the history (pattern) of earnings matters to investors (Barth, Elliott, Finn, 1999), and that revisions of this history affects investors’ decisions (Lev, Ryan, Wu, 2008).
Significant deviations between estimates and realizations change the pattern of earnings, and therefore call for disclosure of revised earnings.
The result: an improved “history of the firm.”
This is done routinely in the national income numbers (GDP, unemployment).

Lastly, 21
The world benefitted from so many
Japanese innovations and contributions,
perhaps it is time that the accounting world
will benefit from a Japanese accounting
makeover.
