10. Demand
The desire, ability, and willingness to buy a product.

11. Demand
Demand Schedule - The listing (table) that shows the various quantities (amounts) demanded of a particular product at different prices.
Demand Curve - Graph showing the quantity demanded at each and every price that the product may have Shows us how price affects demand.

12. Law of Demand
When a product’s price is lower, consumers will buy more of it.
When a product’s price is higher, consumers will buy less of it.

Price Demand

13. Demand Curve
Change in quantity demanded - Movement along the curve that shows the change in the amount purchased in response to different prices.
Change in demand - When things other than price affect demand. The graph will shift to the right if there is more demand or shift to the left if there is less demand.

14. Reasons a Demand Curve will Shift
Consumer Income: Income increases - curve shifts right; Income decreases - curve shifts left
Consumer Tastes: Good advertisement or celebrity endorsement - curve shifts right; Product goes out of style - curve shifts left
Substitutes: Price of substitute goes up - curve shifts right; Price of substitute goes down - curve shifts left

15. Reasons a Demand Curve will Shift
Complements: related goods, use of one increases the use of the other Price of complement goes up - curve shifts left; Price of complement goes down - curve shifts right
Change in Expectations: If you expect something better to come out - curve shifts left; If you expect something to be scarce in the future - curve shifts right
Number of Consumers: More consumers - curve shifts right; Less consumers - curve shifts left

16. Which determinate of demand explains the change in demand.
There are negative reports in the news about the safety ratings on Chevrolet vehicles.
If personal income tax rates increase, the demand for most normal goods will decrease.
An increase in the price of ice cream will cause consumers to buy fewer ice cream cones.

17. Law of Supply Suppliers offer more for sale at high prices.
Supplier offer less for sale at low prices.

18. Supply
Supply Schedule - listing of the various quantities (amounts) of a particular product supplied at all possible prices in the market
Supply Curve - graph showing the various quantities supplied at each and every price that a product might have in the market

19. Supply
Change in quantity supplied - the amount offered for sale in response to a change in price.
Causes movement along the supply curve
Change in supply is when suppliers offer different amounts of products for sale at all possible prices in the market
Cause the curve to shift

20. Factors that cause the supply curve to shift
Cost of inputs: Cost of inputs (such as labor or packaging) drops, producers are willing to supply more, and the curve shifts to the right
Cost of inputs rises, producers offer fewer products for sale and the curve shifts to the left.

21. Factors that cause the supply curve to shift
Productivity: Workers are more productive, more of a product will be produced at every price, curve will shift right.
When workers are unproductive, less of a product will be produced, the curve will shift left.

22. Factors that cause the supply curve to shift
Technology: New technology lowers the cost of production and increases productivity, which shifts the curve to the right Sometimes the equipment breaks down which causes a business to be less productive, and the supply curve shifts to the left.

23. Factors that cause a supply curve to shift
Expectations: If a business thinks the price of a product will go up, then they will decrease their supply for now and the supply curve will shift left.
If a business thinks the price will be lower in the future, then they will want to produce and sell as many as they can now, so supply will increase and the curve will shift to the right

24. Factors that cause the supply curve to shift
Government Regulation: When the government establishes tighter regulations, less is produced, curve shifts left When there is is not much government regulation, supply increases, curve shifts right

25. Factors that cause the supply curve to shift
Number of Sellers: When a lot of sellers enter the market, more is supplied, and the curve shifts to the right
When sellers exit the market, less is supplied, and the curve shifts to the left.

26. The price of wood pulp rises. How does that affect the supply of paper?
If Nabisco stopped producing chocolate chip cookies, what would happen to the supply of cookies?
The price of manicures goes up. How does that affect the supply of manicures?

27. The use of 360-degree, zero-turn lawn mowers allows lawn-service providers to mow twice as many lawns in a given day. What happens to the supply of lawn service?

28. Price Floors and Ceilings
Price Floor: price is not allowed to decrease below a certain level. Examples: minimum wage, agricultural price supports.
Price Ceiling: price is not allowed to increase above a certain level. Example: rent controls.
