The law of demand states that quantity demanded increases when price decreases, but why? Two reasons why the demand curve slopes downward are the substitution effect and the income effect. The income effect states that when the price of a good decreases, it is as if the buyer of the good's income went up. The substitution effect states that when the price of a good decreases, consumers will substitute away from goods that are relatively more expensive to the cheaper good. Learn about the role of the income effect and the substitution effect on the shape of the demand curve in this video.
The seventh episode of our podcast series discusses the supply side of the market – the law of supply, slope of the curve and the difference between a change in supply and a change in quantity supplied.
This series of slides aids students in reviewing the determinants of supply and demand, provides an exercise for them to choose which of the curves shift and why, and allows them to determine which curve will shift given a market event.
This resource is a brief exercise to help students work with supply and demand and also to help students recognize how markets are connected.

Supply and demand are among the most fundamental concepts in economics. An understanding of these topics helps students better understand the economic world in which they live. This course includes three interactive lessons that introduce supply, demand and market equilibrium. This course uses a fictitious chocolate market to help explain the concepts.
According to Professor Michael Munger of Duke University, prices are akin to magic. In this video, Professor Munger explains how prices convert countless pieces of dispersed, complex information into a single signal that conveys to sellers what they should do to best benefit society.
