If people are doing the best with what they have, we should be able to observe a predictable pattern of behavior over time regarding their willingness to sell goods and services at various prices.

Exploring Equilibrium

In this video, we’ll review equilibrium in the adjustment process, showing that the equilibrium price is the only stable price. Then we’ll take a look at equilibrium quantity, where quantity demanded is equal to quantity supplied, and how this plays out in a free market economy that seeks to maximize gains from trade.

Demand, Supply and the Market

A lesson plan on demand, supply, and the market.

This lesson focuses on suppliers and demanders, the participants in markets; how their behavior changes in response to incentives; and how their interaction generates the prices that allocate resources in the economy. Learning about the reaction of demanders and suppliers to price, and the impact of non-price conditions (the determinants of demand and supply) creates a foundation for understanding the dynamism of markets. Examining the interaction of consumers and producers as they respond to market conditions also generates an appreciation for the role of prices in transmitting information that coordinates the economic response to scarcity. The dynamics of the market, a vital part of students’ understanding of economics, may be explained with tables and narrative, or with graphs, or both – whatever is best suited to individual learning styles.

The concept of supply and demand is often considered the heart and soul of economics. It is the foundation for much of what is studied in the field, and understanding how supply and demand affect the economy can help us to recognize economics everywhere in our daily lives. (The British classical economist J.R. McCulloch is attributed with the famous saying that you can make a parrot an economist if you only teach it to say "supply and demand.") The supply and demand infographic highlights basic concepts such as the laws of supply and demand, changes in demand and supply versus changes in the quantity demanded and the quantity supplied, the determinants of demand and supply, and market equilibrium.
