What is the difference between 'command-and-control' regulation and 'market-based' regulation?

• A. Command-and-control regulation uses market-based pricing.
• B. Market-based regulation uses price signals or incentives to influence behavior.
• C. Command-and-control is always more flexible and cost-effective.
• D. Market-based regulation sets fixed limits on emissions.

Answer: (B)

The main idea is how regulation nudges firms to change their behavior: by attaching a price to pollution or by mandating specific rules. Market-based regulation uses price signals or incentives to influence behavior, such as taxes on emissions or permit markets where firms can buy or sell allowances. This approach lets each firm choose the most cost-effective way to reduce pollution, often lowering overall costs because reductions are pursued where they are cheapest. Command-and-control regulation, on the other hand, sets explicit limits or requires particular technologies for everyone, which can be rigid and more costly since it doesn’t let firms select the cheapest path to compliance. So the description that market-based regulation uses price signals or incentives to influence behavior is the best fit. The other statements either mix up how command-and-control works, claim unnecessary flexibility for it, or describe market-based approaches as fixed limits instead of price-driven tools.
