What is the economic principle of supply and demand?

The economic principle of supply and demand describes the relationship between the availability of a good or service (supply) and the desire for that good or service (demand). This fundamental concept in economics explains how market prices are determined. When supply exceeds demand, prices tend to fall, while if demand exceeds supply, prices typically rise. This interaction establishes a balance in the market, guiding producers and consumers in their economic decisions.

The other options, while related to economics, do not accurately capture the essence of the supply and demand principle. Financial independence of a country refers to broader economic stability and does not specifically relate to the dynamic between supply and demand. Governmental deficits and surpluses deal with fiscal policy and budgeting rather than market behavior. Lastly, focusing solely on consumer spending overlooks the role of producers and the supply side in determining market conditions. Understanding the balance between supply and demand is essential for comprehending how markets function and prices are set.
