Question

Quizplus · Accepted Answer

De-merit goods are those goods which are harmful to the consumers or society. Tobacco is a de-merit good which is over consumed when left to the market mechanism. This is because the market mechanism does not take into account the negative externalities associated with tobacco consumption, such as health problems and environmental pollution. As a result, the price of tobacco products does not reflect their true social cost, leading to overconsumption by consumers.
