Look at These Prices!: Introduction


As the saying goes, “Everything has a price.” The question for anyone trying to understand our economy is, “Why that particular price?”

In Supply, Demand, and the Invisible Hand we saw how supply and demand interact in the market so that the “right” amount of goods and services is produced. That section also introduced the price mechanism and its role in determining supply and demand. In this section, we learn how the consumer's need for a product affects demand and how market interventions, such as sales taxes and rent control, affect supply, demand, and prices.
