Mixed Economies Involve Government Intervention

Steps:

• Recall that a mixed economy combines private markets with government regulation to balance efficiency and equity.
• Examine option A: Claims no government role in prices, which contradicts intervention in mixed systems.
• Check B, C, D: All align with government roles in taxation, profit regulation, and public services.
• Conclude A does not fit as a characteristic.

Why A is correct:

• Mixed economies feature government price controls (e.g., antitrust laws or subsidies), so "no role in setting prices" violates the definition of blending market and command elements.

Why the others are wrong:

• B: Taxation is a core government tool in mixed economies to fund services and redistribute income.
• C: Regulations like price caps prevent monopolistic excessive profits, a standard feature.
• D: Governments supply public goods (e.g., infrastructure) that private firms avoid due to non-profitability.

Final answer: A
