Final answer:
The U.S. has a mixed but primarily market-oriented economy with some government intervention (option b), unlike command economies with extensive government control.
Step-by-step explanation:
The type of economy that the United States has is a mixed economy. This means that the U.S. economy combines elements of both command and market systems but is more positioned toward the market-oriented end of the spectrum, characterized by private ownership and minimal government interference in economic decisions. However, the government does play a role for example in regulating certain industries, providing social services, and implementing policies to influence the economy.
When looking at economies worldwide, those with more economic freedom are more likely to be market economies. Conversely, countries with more government control and planning are closer to command economies. The Heritage Foundation's economic freedom index provides insights into the degree of market orientation of different countries. For instance, many European and Latin American countries, while market-oriented, have more government involvement than the U.S. In contrast, China and Russia have moved towards a more market-oriented system over the past decades but are still considered closer to command economies.
