The act of artificially manipulating market supply to increase prices does exist in reality, but it usually involves illegal or unethical methods and may have serious consequences. The following is an objective analysis of this issue, emphasizing legal and ethical risks, and providing relevant background knowledge： --- ###1. Common market manipulation methods (high risk and illegal) 1. **Monopoly or oligarchic alliance** -By controlling most of the industry's supply (for example, OPEC affects oil prices by restricting production), or by conspiring between companies to reduce production (cartels). However, such acts violate anti-monopoly laws in most countries. 2. **Hoarding strange** -Acquire and hoard a large number of commodities (such as rare metals and agricultural products) in large quantities, creating artificial shortages. For example, the cotton hoarding incident in 2010 caused prices to skyrocket, and the companies involved were subsequently investigated. 3. **Manipulation of false information** -Spreading false news of supply shortages, natural disasters, or policy changes, causing panic buying in the market. Typical cases include Enron artificially creating power outages to increase electricity prices during the California energy crisis. 4. **Manipulate the production cycle** -Companies deliberately delay production or destroy stocks (such as the dumping of milk in the 1929 economic crisis), but the supervision and supervision of public opinion in modern society make such behaviors unsustainable. --- ###2. Legal and ethical risks 1. **Legal consequences** -**Anti-monopoly Law**: For example, the U.S. "Sherman Act" and China's "Anti-Monopoly Law" both prohibit market manipulation, and violators face huge fines (up to 10% of global turnover) and criminal liability for executives. -**Securities and Commodities Law**: In financial markets, manipulating commodity or stock prices may constitute a crime (such as Section 6(c) of the U.S. Commodity Trading Act). -**International sanctions**: Cross-border manipulation may trigger a joint investigation by multiple countries, such as a 5 billion euro fine by the European Commission against the auto parts cartels. 2. **Economic backlash** -Inflated prices have led to shrinking demand or the rise of alternatives (for example, after the manipulation of rare earth prices from 2014 to 2016, countries accelerated the development of alternative materials). -Corporate reputation is damaged and long-term customers are lost. 3. **Ethical issues** -Harm the interests of consumers, exacerbate social inequality, and may cause public protests (such as the “drug price hunt” Shkreli was criminally sued after raising the price of AIDS drugs by 55 times). --- ###3. Business strategies for legally regulating supply Companies can optimize pricing in the following compliance methods, but they need to be based on the real supply and demand in the market： 1. **Dynamic pricing** -Adjust prices based on real-time supply and demand (such as floating pricing systems in the aviation industry and hospitality industry). 2. **Scarcity marketing** -Limited sales or high-end customization (such as the luxury industry), but consumers must be clearly informed and the information is not fictitious. 3. **Technological innovation to control production capacity** -Maintain market position through patents or technical barriers (such as the monopoly of lithography machine technology in chip manufacturing), but avoid abuse of dominant position. --- ###4. Historical cases and lessons learned 1. ** De Beer Diamond Monopoly (20th century)** -Maintaining high prices by controlling the global supply of diamond mines, the 21st century has declined due to antitrust litigation and the rise of synthetic diamond technology. 2. **Libor interest rate manipulation case (2012)** -A number of banks conspired to manipulate the London Interbank Offered rate, and were eventually fined more than US99 billion, and the executives involved went to jail. 3. **Garlic speculation (China, 2009-2010)** -Tourism speculation caused the price of garlic to rise 40 times a year, and the subsequent price crash wiped out speculators. --- ###5. Summary Although there are theoretically means to increase prices by controlling supply, the modern legal system and market supervision (such as big data monitoring and whistle-blower protection systems) make this kind of behavior extremely risky. Companies should achieve sustainable profitability through technological innovation, brand building and efficiency improvement, rather than relying on short-term manipulation. Consumers and investors also need to be vigilant and maintain rational judgments about abnormal price fluctuations.
