The principle of supply and demand describes the relationship between product availability and consumer desire. In a market economy, supply refers to the quantity of a product that producers are willing and able to sell at various prices, while demand refers to the quantity of a product that consumers are willing and able to purchase at those prices. The interaction between supply and demand determines the equilibrium price of a good or service, where the quantity supplied equals the quantity demanded. This principle illustrates how changes in consumer preferences, production levels, or market conditions can lead to fluctuations in pricing and availability of products.

In contrast, concepts such as price stability over time focus on market conditions without directly discussing the dynamics of supply and demand. The allocation of resources in an economy encompasses broader economic principles beyond just the supply and demand mechanism, including factors such as resource scarcity and choices made by various economic agents. Government regulation on prices can affect market behavior and outcomes, but it is not an intrinsic property of the supply and demand relationship itself, which primarily centers on the natural interaction between buyers and sellers in a free market.
