Information Asymmetry in Market Economies

Steps:

• Define a market economy as a system where prices, production, and distribution are guided by supply and demand with minimal government intervention.
• Identify common disadvantages: inefficiency from externalities, inequality, and imperfect information.
• Evaluate choices against these: A contradicts consumer sovereignty; B matches information failure; C describes government intervention, not pure markets; D ignores profit motives.
• Select B as it directly highlights a core flaw where buyers and sellers have unequal knowledge.

Why B is correct:

• In market economies, asymmetric information (per economic theory like Akerlof's "Market for Lemons") leads to adverse selection and moral hazard, causing market failures as consumers cannot make fully informed decisions.

Why the others are wrong:

• A: Market economies prioritize consumer choice through demand-driven allocation.
• C: Subsidies are a government tool, absent in pure market systems, and can distort efficiency.
• D: Profit incentives drive work and innovation in competitive markets.

Final answer: B
