What role do supply and demand play in determining prices?

Supply and demand are fundamental concepts that play a critical role in determining prices in a market economy. Market equilibrium refers to the point at which the quantity supplied meets the quantity demanded, resulting in a stable price for goods and services. When demand for a product increases or decreases while supply remains constant, the price typically adjusts accordingly. Conversely, if supply changes while demand remains constant, prices will also fluctuate to reach a new equilibrium.

Market dynamics are constantly at play. For instance, if a new technological advancement makes production cheaper, suppliers may increase their supply, which could lead to a decrease in price. Conversely, if a product becomes highly desirable and demand surges, prices may rise until a new equilibrium is established where consumer willingness to pay matches the available supply.

This interaction illustrates how supply and demand collectively establish market equilibrium, reflecting the preferences of consumers and the capacity of producers. The correct understanding of this relationship is essential for grasping how prices are set in a competitive market context, distinguishing it from concepts like government regulations or fixed pricing structures that do not allow for this natural adjustment.
