Provide an example of command-and-control regulation.

• A. Emissions standards requiring firms to meet fixed limits or face penalties.
• B. Cap-and-trade program for emissions.
• C. A pollution tax.
• D. Self-regulation by industry groups.

Answer: (A)

Command-and-control regulation is when the government sets explicit limits or mandates and enforces penalties for noncompliance. An emissions standard that requires firms to meet fixed emission limits and imposes penalties if they exceed those limits is a classic example. The regulator dictates exactly how much pollution is allowed and uses penalties to ensure firms comply, leaving little room for firms to choose alternative, cost-saving approaches.

This stands in contrast to market-based or voluntary approaches. A cap-and-trade program allocates pollution permits and lets firms trade them, which uses market mechanisms rather than a single fixed limit for every firm. A pollution tax uses price signals to influence behavior rather than mandating a specific emission limit. Self-regulation by industry groups lacks government-imposed penalties or standards.
