20 | A Market: Supply and Demand
Supply and demand curves help us to predict how much will be traded and at what price under particular circumstances.

In this lesson, we investigate how prices reach equilibrium and how the market works like an invisible hand coordinating economic activity. At equilibrium, the price is stable and gains from trade are maximized. When the price is not at equilibrium, a shortage or a surplus occurs. The equilibrium price is the result of competition amongst buyers and sellers.
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.
You are about to participate in an economic experiment. The market structure used in this experiment is known as a “double-oral auction.”

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.
Does the equilibrium model work? Nobel Prize winner Vernon Smith conducted experiments testing this model.

In this video, we explore the relationship between price and quantity supplied. Why does the supply curve slope upward?

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.

Caltech economists put supply and demand experiment from 1960s to the test
This tool from Marginal Revolution University will ask students 10 questions about whether an event causes a shift in the demand curve or a shift in the supply curve. This tool is perfect for learning supply and demand, or for reviewing if you've already covered the topic!
How do increases or decreases in demand affect the demand curve? An increase in demand means an increase in the quantity demanded at every price.
This video looks at both the horizontal and vertical methods for reading the demand curve, how demand curves shift, and consumer surplus.
An inferior good is a good or service where your demand goes down when your income goes up, and vice versa.
What just happened to the price of oil, and what does it tell us about the world?
Before coronavirus hit, most of the U.S. GDP was driven by consumer demand for goods and services. And American demand for stuff drove growth all around the world.
