Meta-Analysis
Detailed Results
Summary of Key Findings
• The corporate social responsibility (CSR)
literature is more meaningful and coherent
than most researchers realize.
• Statistically significant relationship between
CSR and corporate financial performance
(CFP).
• These relationships are very unlikely to be
spurious or caused by publication effects.
Orlitzky’s Hypotheses
• There will be a statistically significant
relationship between CSR and CFP.
• The two factors will mutually reinforce one
another.
• The correlation will be shown to be due to:
– Improved managerial competency
– Improved corporate reputation
• Much of the variance in studies will be due to:
– Sampling or measurement error
– Different data sources

What is Meta-Analysis?
•
•
•
•
•
Complex statistical technique.
Goal: “Make sense out of nonsense.”
Aggregates many studies.
Widely used in medical research.
Use in management/financial research is new.
• “Such after-the-fact, or retrospective, analysis
falls pretty low on the scale of scientific reliability.
But sometimes it provides good clues about
where problem areas may lie.”
- Time magazine, 9/3/01
Meta Analysis and Vioxx

Meta-Analysis of COX-2s in 2001
• “The annualized myocardial infarction rates for COX-2 inhibitors in
both VIGOR and CLASS were significantly higher than that in the
placebo group of a recent meta-analysis of 23,407 patients in
primary prevention trials (0.52%): 0.74% with rofecoxib (P =.04
compared with the placebo group of the meta-analysis) and 0.80%
with celecoxib (P =.02 compared with the placebo group of the
meta-analysis). The available data raise a cautionary flag about the
risk of cardiovascular events with COX-2 inhibitors.”

• (Merck’s own meta-analysis did not show this effect.)
Final Warning
• [In an FDA-funded study by Kaiser Permanente]
“heart attack rates tripled for patients taking
Vioxx in doses higher than 25 milligrams per
day, according to the study. Lower doses of the
drug also increased the risk of a heart attack,
‘but not significantly so,’ the study indicated.
Merck defended the safety of its $2.5-billion-ayear drug and questioned the study."

The End
• “Merck &. Co., Inc. today announced a voluntary
worldwide withdrawal of VIOXX® (rofecoxib), its
arthritis and acute pain medication. The
company's decision, which is effective
immediately, is based on new, three-year data
from a prospective, randomized, placebocontrolled clinical trial...”

Bringing Meta Analysis to CSR
• Large body of quantitative work
• Controversy over:
– Definitions of key variables
– Methodology
• McWilliams and Siegel: Misuse of event studies
– Interpretation of results
• Griffin and Mahon: “25 years of incomparable research”
• Margolis and Walsh: Research is generally weak, but see
positive relationship
• “Despite the intensity of study directed at it, the relationship
between CSP and corporate financial performance (CFP)
remains in dispute.” – Barnett and Salomon, 2003
The Results – Hypothesis #1
• Hypothesis 1: There will be a statistically
significant relationship between CSR and
CFP.
• Supported:
– CSR explains 24% of the variance in CFP.
– File Drawer Analysis: 1,037
The Results – Hypothesis #2
• Hypothesis #2: The two factors will
mutually reinforce one another.
• Supported:
– By using time lags, Orlitzky finds that CFP is a
predictor of future CSR.
– But CSR also predicts CFP.
– “Taken together, these findings suggest a
virtuous cycle with quick cycle times or
concurrent bidirectionality.”
The Results – Hypothesis #3
• Hypothesis #3: The correlation will be
shown to be due to:
– Improved managerial competency
– Improved corporate reputation
• Supported:
– Both internal (competency) and external
(reputation) measures of CSR predicted CFP.
– Of the two, the reputation effect was stronger.
The Results – Hypothesis #4
• Hypothesis #4: Much of the variance in studies
will be due to:
– Sampling or measurement error
– Different data sources
• Supported:
– Sampling and measurement issues accounted for
24% of the variance across studies.
– Reputational measures were better predictors of CPF
than social audits (e.g., KLD ratings).
– Impact of CSR on CFP was stronger with accounting
measures than market measures.
