Which pairing best illustrates a free-market approach and a government-intervention approach in policy design?

• A. Carbon pricing using market mechanisms; universal healthcare with state-led provision.
• B. Universal healthcare with tax credits; carbon bans with decentralized markets.
• C. Price controls on essential goods; private charity funding instead of regulation.
• D. Subsidies for all public services; deregulation with no environmental oversight.

Answer: (D)

The main idea being tested is recognizing a pairing where one policy design leans on government intervention and the other on free-market mechanisms. Subsidies for all public services represent government intervention because they involve direct public spending and centralized decision-making to shape what services are provided and how they’re funded. Deregulation with no environmental oversight embodies a free-market stance by removing governmental constraints, allowing private actors to operate more freely and rely on market incentives rather than rules. This clear split between state-directed support and reduced regulation best illustrates the contrast between interventionist design and market-based design.

Other options mix elements in ways that aren’t as clean in showing one side as free-market and the other as government intervention. For example, market-based tools like carbon pricing still involve government design and oversight, even though they use market signals; universal healthcare with state-led provision is primarily government-led; price controls are government-imposed; private charity funding instead of regulation isn’t a full free-market policy.
