What are the distinguishing features of a market economy, and how does government intervene?

• A. Central planning and state ownership of all resources
• B. Private property, voluntary exchange, competition, and consumer sovereignty; government intervention via regulation, taxation, and public goods
• C. No government involvement in economic decisions
• D. Resources allocated randomly by chance

Answer: (B)

In a market economy, private property, voluntary exchange, competition, and consumer sovereignty guide economic activity. People have the right to own resources and trade them freely, prices emerge from supply and demand through voluntary transactions, competition pushes producers to be more efficient, and consumers influence what gets produced through their choices. The government often steps in to keep markets fair and functional by regulating practices to prevent abuses, collecting taxes to fund public services, and providing public goods like roads, schools, and national defense. This combination—private property and voluntary exchange with competition, alongside government roles such as regulation, taxation, and public goods—describes how market economies operate and how government intervention fits in. By contrast, central planning and state ownership describe a system where the government makes production decisions; no government involvement describes an unrealistic absence of any public policy; and random allocation of resources wouldn’t create the coordinated outcomes a market aims for.
