Are you ready to look a bit deeper at why elasticity changes despite having a linear demand curve? This video explains how the quantity of demand of good or service changes when it price changes. [6:00]

Discover what a demand curve with constant unit elasticity would look like. [4:37]

Clarification on the relationship between total revenue and elasticity. [8:25]

Examines how total revenue and elasticity are related. [11:31]

An explanation of how the elasticity of supply works.

A video [7:04] explaining how price elasticity relates to demand changes in response to income elasticity.

The burden of a tax falls most heavily on someone who can't adjust to a price change. That means buyers bear a bigger burden when demand is more inelastic, and sellers bear a bigger burden when supply is more inelastic.

This article discusses how quantity demanded react to artificial constraints on price.
