How can information asymmetry lead to misallocation of resources? Provide an example used in economic learning.

• A. Perfect information always yields efficient outcomes
• B. Equal information about risk by buyers and sellers yields inefficiency
• C. If buyers or sellers lack information about quality or risk, markets may allocate resources inefficiently; example: used-car market with hidden defects
• D. Information asymmetry never affects market outcomes

Answer: (C)

When buyers and sellers don’t have the same information about quality or risk, prices can’t accurately reflect true value, so resources don’t flow to where they would be most beneficial. This information gap distorts decisions and leads to a misallocation of resources.

A classic example is the used-car market with hidden defects. Sellers usually know much more about a car’s condition than buyers. If a car has problems that aren’t easy to detect, buyers may be wary and willing to pay only a price that reflects average or uncertain quality. Good-quality cars end up underpriced because buyers fear hidden faults, while lemons (low-quality cars) may flood the market and be accepted at lower prices. As a result, resources—money and time—are funneled toward lower-quality cars, and the overall welfare in the market falls. This illustrates how information asymmetry can cause the market to misallocate resources.

The other statements assume perfect or equal information or deny any effect from information gaps, which would remove or contradict the mechanism that causes the misallocation.
