Interpersonal Corruption Market and Laboratory Evidence
Corruption is a pervasive problem for organizations
ANNUAL COSTS TO AMERICAN FIRMS• Prescription drug fraud: $72.5 billion
• Employee theft: $52 billion
• Corporate fraud: $37 billion
• Mortgage fraud: still unknown
The sources of corruption are important to identify
I research how interactions between individuals and organizational environments influence corrupt behavior
SOURCES OF CORRUPT BEHAVIOR• Financial incentives and extrinsic motivation
• Social comparison and envy
• Network or peer-based intrinsic motivation
It is the role of individual relationships and interactions that makes corruption “interpersonal”
I present two papers on one source of interpersonal corruption --- comparison of wealth
1. Robin Hood under the Hood (w/ Francesca Gino)– Forthcoming at Organization Science
2. Dishonesty in the Name of Equity (w/ Francesca Gino)– Forthcoming at Psychological Science
These papers demonstrate two different approaches to understanding individual fraud and corruption
Several mechanisms may link wealth-based comparisons to corrupt behavior
• Inequity may lead to emotional distress or decreased utility – Discrepancies in wealth or income may lead to seemingly
irrational behavior – Inequity-based envy may lead to sabotage, unwillingness to help
• A real or perceived relationship with the victim or beneficiary may influence the decision to engage in helpful corrupt behavior– Empathy/sympathy may motivate economic decisions
• Favoritism toward similar others in corruption may be: – Subconscious (Bazerman and Banaji, 2004; Zitzewitz, 2006;
Price and Wolfers, 2007)– Based in emotions (Cuddy et al., 2007; Schweitzer and Gibson,
2008)
In “Robin Hood” we use large-sample econometrics to study wealth-based discriminatory fraud in a market setting
EMISSIONS TESTING MARKET• There are financial and personal motivations for
fraudulently passing cars• Firm: Customer loyalty, repeat business• Inspector: Relationships, envy/empathy, bribery
• Inspectors have broad discretion to illegally temporarily lower emissions through engine additives, removal (or addition) of parts, or adjustment of tailpipe probe
This paper is unique in observing wealth-based corruption for an entire market
Fraud in the vehicle emissions testing market is widespread
VEHICLE EMISSIONS FRAUD
• Vehicles must test below a discrete cutoff for hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxide (NOx)
• Vehicle emissions may be illegally temporarily lowered through engine additives, removal (or addition) of parts, adjustment of tailpipe probe, or clean-piping (use of bogey cars)
• Hubbard’s (1998, 2002) evidence of fraud from 1992 CA data is supported by extensive anecdotal evidence
• Testing facilities have strong incentives to keep the gross polluting cars of their customers on the road

Do “Robin Hood” inspectors discriminate based on wealth in helping vehicles pass?
EMPIRICAL APPROACH• Over 9 million individual tests from 2001-2004 in a major MSA with vehicle
characteristics, inspector, facility, date, and test results
• We identify perceived customer wealth by whether or not they own a luxury vehicle
• We identify inspector fixed-effects for each car segment (luxury/standard) while controlling for vehicle, geographic, facility, and time characteristics
• We observe whether luxury and standard fixed effects are significantly different for specific inspectors
• We compare the patterns of discrimination with counterfactual simulations
We sample the 249 (out of 18,763) largest volume inspectors

“Robin Hood” suggests that customer wealth may influence employee corruptionKEY FINDINGS1. Many inspectors illegally help lower-wealth customers pass
emissions tests more than higher-wealth customers
2. This discriminatory fraud not explained by geography or facility, but correlated with per-capita income
3. We cannot fully separate intrinsic from extrinsic motivation or organizational policy from discretionary decisions
4. We also cannot control for selection in the labor market
Let’s go to the lab!
“In the Name of Equity” studies how individuals weigh financial and equity considerations in corrupt behavior
CORRUPTION IN THE NAME OF EQUITY
• Does inequity motivate corrupt behavior that hurts or helps others?
• How do individuals trade off between financial incentives and equity-based motivation?
This paper is the first to study how inequity motivates dishonest helping
Inequity (unfairness) causes psychological distress that individuals take action to relieve
TYPES OF INEQUITY• Negative inequity: Disadvantageous rewards compared to others
– Emotional distress from envy• Positive inequity: Advantageous rewards compared to others
– Emotional distress from guilt• Empathetic inequity: Disadvantageous rewards for a similar peer
compared to others– Emotional distress through empathy
Do individuals engage in helpful and hurtful corruption to relieve this distress?
We use a standard experimental design, but manipulate equity between participants
EXPERIMENTAL PROCEDURE1. Approximately 120 participants publicly flip a fair digital coin:
heads=$20, tails=$02. Each participant is randomly assigned to a role, “solver” or
“grader”, then paired off3. Solvers complete four rounds of anagrams4. Graders evaluate how many rounds the goal was reached by
their partner5. Graders then paid the solvers $2/round and received their
own payment
Solvers’ cash wealth is always visible in transparent lanyards
Initial lottery creates four equity-based conditions
Do financial and equity considerations motivate graders to dishonestly help or hurt others?

We run three studies with different financial incentives
FINANCIAL INCENTIVES1. Grader paid flat rate
– No financial incentive to misrepresent
2. Grader pay equal to solver pay– Financial incentive to dishonestly help
3. Grader residual claimant on money not earned by solver– Financial incentive to dishonestly hurt
Is equity worth real money?
Grader counts with no financial incentive

Both financial motivation and emotional distress from inequity drive corrupt behavior
MOTIVATORS OF CORRUPT BEHAVIOR• Financial motivation: Individuals on average respond to
incentives• Equity
– Positive inequity: Guilt increases dishonest helping– Negative inequity: Envy increases dishonest hurting and eliminates
dishonest helping– Empathetic inequity: Empathy with similar others increases
dishonest helping
• Personal ethics and fear of detection/punishment are other important, unmeasured factors
People will trade off absolute payoffs for relative payoffs
Collectively, these papers suggest that levels of equity in personal interaction motivate corrupt behavior
• “Robin Hood”: Workers discriminate in fraud based on perceived wealth– How much of the motivation is extrinsic or intrinsic?
• “Abundance”: Individual corruption is motivated by the proximity of wealth– Does this effect generalize to organizations and non-monetary wealth?
• “Equity”: Equity considerations influence decisions to dishonestly help or hurt others– Do managers or other workers dishonestly report information in
response to inequity?
The empirical evidence still leaves many questions unanswered
The next step empirically is to study organizations where extrinsic and intrinsic motivation can be separated
STUDIES IN DEVELOPMENT• How compensation systems influence peer effects and theft
among department store salespeople• How relationships between pharmacists and doctors influence
fraud• How interactions between doctors and patients influence
unnecessary drug prescriptions• Factory-based field experiments on how comparisons of
performance-based pay influence effort, sabotage, and turnover• Field experiments on how employee-customer interactions
influence cheating• Compensation changes on cruise ships• Interpersonal corruption in traffic stops
The overall goal of this research is to help firms and policy makers reduce corrupt behaviorORGANIZATIONAL APPLICATIONS• How do we better design compensation systems to account for both
economic and psychological mechanisms?– Sorting on ability and fit– Extrinsic and intrinsic motivation
• How do we better predict when discretionary behavior will be counter to firm interests– Decentralized decision-making yields information and adaptation
benefits– Moral hazard and intrinsically-motivated actions
• How do we design organizations to minimize perceptions of inequity or associated adverse reactions?– Better communication of performance or contribution– Better control of compensation information– Better design of organizational environment
