Price Mechanism Rations by Willingness to Pay

Steps:

• Identify the price mechanism: Prices adjust to balance supply and demand, allocating scarce goods.
• Recognize rationing role: Higher prices limit access to those valuing the good most (via payment).
• Evaluate advantages: Focus on efficient, non-arbitrary distribution without central planning.
• Match to options: Select the one highlighting fair access based on market rules.

Why C is correct:

• In competitive markets, the price mechanism allows consumption for anyone able to pay, ensuring efficient allocation per Adam Smith's "invisible hand" principle.

Why the others are wrong:

• A: Allocation follows wants weighted by willingness to pay, not purely consumer preferences.
• B: Suppliers can earn profits, including potentially high ones, in response to demand.
• D: Wealth-based allocation is a disadvantage, as it favors the rich over equitable distribution.

Final answer: C
