This video lesson from Khan Academy is intended for students who are taking the AP Macroeconomics course. Students will examine the two extremes of elasticity: perfectly elastic and perfectly in elastic demand. The extremes can help...

Looking a bit deeper at why elasticity changes despite having a linear demand curve. This resource is designed as a review for the AP Microeconomics Test or a college-level microeconomics course.

In this video lesson, explore a simple way to calculate the price elasticity of demand, how to interpret that calculation, and how price elasticity of demand varies along a demand curve. This resource is designed as a review for the AP...

This video lesson explains why we calculate percent changes in a strange way when calculating elasticities. This resource is designed as a review for the AP Microeconomics Test or a college-level microeconomics course.

There are several factors that affect how elastic (or inelastic) the price elasticity of demand is, such as the availability of substitutes, the timeframe, the share of income, whether a good is a luxury vs. a necessity, and how narrowly...

Walk through the logic of determining what kind of good has the most elastic demand in this video. This resource is designed as a review for the AP Microeconomics Test or a college-level microeconomics course.

This video lesson provides a case of price elasticity of demand, s demand curve with a constant unit elasticity. Explore what such a demand curve would look like in this video.

In this video lesson from Khan Academy, students will explore how changes in a few factors, including income, population, and consumer preferences, affect the demand curve. This resource is designed as a review for the AP Macroeconomics...

In this video lesson from Khan Academy, students will explore what happens when both supply and demand are simultaneously changing. This resource is designed as a review for the AP Macroeconomics Test or a college-level macroeconomics...

This video lesson from Khan Academy will help students understand the difference between the effects of the changes in supply with changes in the quantity supplied. This resource is designed as a review for the AP Macroeconomics Test or...

This video lesson from Khan Academy explains the differences between a change in the quantity demanded for a good (which causes a movement along a demand curve) and the change in a good's demand (which causes the entire demand curve to...

This video is an overview of full reserve banking in comparison to fractional reserve banking. [7:32]

This video explains how the price of one good impacts the quantity demanded of another. [11:19]

One of the biggest worries associated with deflation is a deflationary spiral, in which low unemployment and a decreasing price level lead to lower unemployment and an even lower price level. [3:50]

Price changes the quantity supplied, but what might cause supply to increase even if the price hasn't changed? In this video, we explore the determinants of supply: those factors that cause an entire supply curve to shift. [6:58]
