Key Business Ethics Case Studies

Why This Matters

These case studies aren't just cautionary tales. They're the foundation for understanding how ethical failures actually unfold in corporate environments. You're being tested on your ability to identify which ethical principles were violated, what systemic factors enabled the misconduct, and how stakeholders were harmed. Exams will ask you to analyze cases through frameworks like stakeholder theory, utilitarianism, deontological ethics, and corporate social responsibility. Each scandal illustrates specific mechanisms: fraudulent accounting, deceptive marketing, toxic corporate culture, or failures of governance.

Don't just memorize company names and fines. Know what concept each case best illustrates. When an FRQ asks about fiduciary duty, you should immediately think Enron or Tyco. When it asks about informed consent, Cambridge Analytica should come to mind. The cases below are grouped by the type of ethical failure they represent, which is exactly how exam questions will frame them.

Financial Fraud and Accounting Manipulation

These cases demonstrate what happens when companies deceive investors and regulators through deliberate misrepresentation of financial health. The core mechanism is the same: executives manipulate numbers to inflate perceived value, enriching themselves while destroying stakeholder trust.

Enron Scandal

• Fraudulent accounting through special purpose entities (SPEs): Enron created off-the-books shell companies to hide billions in debt. On paper, the company looked profitable. In reality, it was drowning in liabilities that investors and employees couldn't see.
• Fiduciary duty violation resulted in 20,000 job losses, $\$74\ \text{billion}$ in shareholder losses, and destroyed retirement savings tied to company stock.
• Auditor complicity is a critical piece of this case. Arthur Andersen, one of the "Big Five" accounting firms, signed off on Enron's books and later shredded documents. The firm's collapse showed how third-party gatekeepers can enable fraud rather than prevent it.

WorldCom Accounting Fraud

• Asset inflation of $\$11\ \text{billion}$: WorldCom recorded ordinary operating expenses (like line costs for network access) as capital expenditures. This made spending look like investment, artificially boosting profits on income statements.
• Largest bankruptcy in U.S. history at the time, wiping out employee pensions and investor savings.
• Catalyst for the Sarbanes-Oxley Act (SOX, 2002), which mandated stricter internal controls, required CEO/CFO personal certification of financial statements, and created the Public Company Accounting Oversight Board (PCAOB) to regulate auditors.

Tyco International Scandal

• Executive theft of $\$600\ \text{million}$: CEO Dennis Kozlowski and CFO Mark Swartz looted company funds for personal luxury, including a notorious $\$6{,}000$ shower curtain and a $\$2\ \text{million}$ birthday party in Sardinia, partly billed to the company.
• Corporate governance failure allowed unchecked executive compensation and self-dealing transactions. The board either didn't know or didn't act.
• Board oversight reforms followed, emphasizing independent directors and compensation committee accountability.

Deceptive Practices and Consumer Harm

These cases involve companies deliberately misleading consumers or regulators about product safety, performance, or practices. The ethical violation centers on informed consent: stakeholders couldn't make rational decisions because they were given false information.

Volkswagen Emissions Scandal

• "Defeat device" software detected when cars were undergoing emissions testing and temporarily reduced nitrogen oxide output to pass. During normal driving, the cars emitted up to 40 times the legal limit of pollutants.
• 11 million vehicles affected globally, with fines exceeding $\$30\ \text{billion}$ and criminal charges against multiple executives.
• Regulatory trust breakdown raised serious questions about whether self-reported compliance data can ever be trusted without independent verification.

Theranos Fraud Case

• Technology that never worked: Founder Elizabeth Holmes claimed a proprietary device called the "Edison" could run hundreds of diagnostic tests from a single finger-prick of blood. In reality, Theranos secretly ran most samples on conventional machines from other companies, and its own devices produced unreliable results.
• Patient safety endangered as people received false medical information that could have affected treatment decisions. This is where the case connects to informed consent in a medical context.
• Startup culture critique emerged, questioning whether the Silicon Valley "fake it till you make it" mentality creates ethical blind spots, especially in industries like healthcare where lives are at stake.

Wells Fargo Account Fraud Scandal

• Roughly 3.5 million unauthorized accounts created by employees desperate to meet aggressive sales quotas. Customers were charged unauthorized fees and some saw damage to their credit scores without ever knowing why. (Initial estimates were 2 million, but later investigations revealed the scope was larger.)
• Toxic incentive structure is the key concept here. The "cross-selling" strategy pressured low-level employees to open eight accounts per customer. Workers who couldn't hit targets were fired, while executives who designed the system collected bonuses.
• $\$3\ \text{billion}$ total penalties and ongoing reputational damage demonstrated how corporate culture can institutionalize misconduct from the top down.

Data Privacy and Digital Ethics

This category addresses the ethical challenges that arise when personal data becomes a commodity and consent mechanisms fail to protect users.

Facebook-Cambridge Analytica Data Breach

• 87 million users' data harvested without meaningful consent through a personality quiz app called "thisisyourdigitallife." The app collected not just the quiz-taker's data but also the data of all their Facebook friends, exploiting platform permissions that users didn't fully understand.
• Political manipulation concerns arose when the consulting firm Cambridge Analytica used this data to build psychographic profiles for targeted political advertising in the 2016 U.S. election and the Brexit campaign.
• GDPR acceleration: The scandal strengthened momentum for Europe's General Data Protection Regulation and sparked global privacy debates. It also raised the question of whether "agreeing to terms of service" constitutes genuine informed consent when users don't understand what they're agreeing to.

Supply Chain Ethics and Global Responsibility

These cases examine corporate responsibility for harms that occur outside direct company operations, in factories, communities, or environments where companies benefit from activity but don't directly control day-to-day conditions.

Nike Sweatshop Controversy

• Subcontractor exploitation: Factories in Vietnam, Indonesia, and China paid workers below living wages in unsafe conditions. Nike's initial defense was that it bore no direct responsibility because it didn't own the factories. This raised a fundamental question in business ethics: does outsourcing production outsource moral responsibility?
• "Race to the bottom" dynamics illustrated how global competition pressures companies to seek the cheapest labor regardless of human cost, with each supplier undercutting the next.
• CSR movement catalyst: After years of boycotts and public pressure, Nike eventually became an industry leader in supply chain transparency, publishing factory audit reports and adopting codes of conduct. This arc shows how reputational pressure can drive genuine reform.

Nestlé Infant Formula Controversy

• Aggressive marketing in developing nations discouraged breastfeeding and promoted formula use in communities where clean water for mixing formula wasn't reliably available. The result was increased infant illness and mortality.
• Vulnerability exploitation is what makes this case ethically distinct. Nestlé distributed free samples to new mothers in hospitals. By the time the samples ran out, many mothers' breast milk had dried up, forcing them to purchase expensive formula they often couldn't afford and couldn't safely prepare.
• The WHO International Code on the Marketing of Breast-Milk Substitutes (1981) emerged directly from this scandal, establishing global ethical marketing standards for infant nutrition products.

BP Deepwater Horizon Oil Spill

• 4.9 million barrels of oil released into the Gulf of Mexico after the Deepwater Horizon rig exploded in April 2010. Investigations revealed a pattern of safety shortcuts and ignored warning signs, including a failed blowout preventer and decisions to proceed despite abnormal pressure test results.
• 11 workers killed and massive ecosystem destruction across Gulf Coast fisheries, wetlands, and wildlife habitats.
• $\$65\ \text{billion}$ in total costs including cleanup, fines, and settlements. This figure is a powerful counter-argument to the claim that cutting safety corners saves money. The ethical shortcut cost BP more than decades of proper safety investment would have.
