Supply and demand is the bedrock of economic theory — the model that explains how prices are set, how markets allocate resources, and why shortages and surpluses occur. Understanding these forces helps you make sense of everything from housing prices and gas costs to why concert tickets get scalped and why minimum wage debates are so contested.
