What two forces determine prices in a market economy?

In a market economy, prices are primarily determined by the forces of supply and demand. Demand refers to the quantity of a good or service that consumers are willing and able to purchase at various prices, while supply represents the quantity that producers are willing to offer for sale. When demand exceeds supply, prices tend to rise, and when supply exceeds demand, prices generally fall. This dynamic interaction helps to allocate resources efficiently within the economy.
