CHAPTER 5—THE SUPPLY CHAPTER 5.1 “What is supply?”
Why does supply increase as price increases? • Let’s think about it. • If you could tutor a kid after school, would you do it for… • $1/hr? • $5/hr? • $7.50/hr • $10/hr? • $20/hr? • If yes, is this price high enough where you would be willing to work more than 1 hr/week? How about 5 hours at this price? Or 20 hours? • $30/hr? • $50/hr? • $100/hr? • $250/hr?
Duh The supply of students willing to stay after school for $250/hr is much greater than the supply willing to stay for $1/hr
Does supply apply only to labor? • In other words, as the price increases, would the production of GOODS also increase? • Personal Examples SUPPLY SCHEDULE OR SUPPLY CURVE?
Classwork • Ch. 5.1 Definition • Subsidy • Identify and briefly describe the 7 reasons why changes in supply occur (p. 116-118).
Reasons for Change in Supply? • Cost of Inputs • Productivity • Technology • Taxes and Subsidies • Expectations • Government Regulations • Number of Sellers

INELASTICITY
The supply curve for products that can be made quickly without huge amount of capital and skilled labor is ________. • ELASTIC • Kites, candy, etc. • INELASTIC • Planes, shale oil ***Unlike demand, ONLY production considerations determine supply elasticity.*** (Substitutes, ability to delay purchase, etc. are not important for supply elasticity)
Finally (for this section)… • Unit Elastic Supply • KEY WORD: PROPORTIONAL (change)
