1)The price elasticity of demand is people’s responsiveness of quantity demanded (or consumption) when there is a change in price. Prior to beginning work on this discussion forum, read Chapter 4 of the textbook.

• Distinguish between a necessity and a luxury.
• How are the price elasticity of demand and total revenue related? Why is the price elasticity of demand important to pricing?
• Your initial post should be a minimum of 300 words.
• 2) Externalities are costs or benefits associated with consumption or production that are not incurred by the consumer or producer and are therefore not reflected in market prices.

Respond to the following:
