Q4MEDIUM

A chemical factory produces industrial solvents and dumps waste into a nearby river, causing health problems for downstream communities. Which of the following best explains why the market fails to allocate resources efficiently in this situation?

A) The factory has monopoly power and can restrict output to raise prices
B) Private marginal costs are less than social marginal costs, leading to overproduction
C) Consumer preferences for environmental quality are not reflected in market demand
D) The government has imposed price controls that prevent equilibrium from forming
E) Information asymmetry prevents consumers from knowing the true quality of the product
Show Answer

Answer: B — The correct answer is "Private marginal costs are less than social marginal costs, leading to overproduction". The factory's private marginal costs exclude the external costs (pollution damage) imposed on society. Since the factory only considers its own production costs when deciding output levels, it produces more than the socially optimal quantity. Option "The factory has monopoly power and can restrict output to raise prices" confuses market power with externalities. Option "Consumer preferences for environmental quality are not reflected in market demand" describes a preference issue but doesn't explain the efficiency failure mechanism. Option "The government has imposed price controls that prevent equilibrium from forming" involves price controls, not externalities. Option "Information asymmetry prevents consumers from knowing the true quality of the product" addresses information problems, which are a different type of market failure unrelated to pollution externalities.

A) The wealth of the richest 1% of the population
B) The poverty rate of a country
C) The income inequality of a country
D) The unemployment rate of a country

Answer: C — The income inequality of a country is correct because the Gini coefficient measures income inequality..
