2. Supply   Supply is the desire and ability to produce and sell a product.   The law of supply states, as prices go up, suppliers will produce more

4. Costs of Production   FIXED COSTS– are expenses that businesses must incur whether they are producing nothing, a little or a lot. INSURANCE RENT LICENSES, FEES

5. Production Costs   VARIABLE COSTS – are expenses that vary as the level of PRODUCTION changes. FarmerAutomobile manufacturer Banana Republic Dairy Queen Variable costs SEEDS FERTILIZER WATER WORKERS STEEL WORKERS MACHINES TIRES GLASS TEXTILES WORKERS ADVERTISIN G ICE CREAM CONES WORKERS SPRINKLES

6. Total Cost   Adding fixed and VARIABLE gives a business their TOTAL COST. TOTAL COST = FC+VC

8. Changes in Supply   Change in Quantity Supplied (MOVER) is an increase or decrease in the amount SUPPLIED due to a change in PRICE. It only moves if it’s a change in the PRICE of that specific product!!!

9. Quantity Price A B C D E F Change in Quantity Supplied

10. Changes in Supply .  Change in Supply (SHIFTER) is when supply changes due to something other than PRICE.

12. 6 Factors for Change in Supply TECHNOLOGY LABOR PRODUCTIVITY INPUT COSTS # of PRODUCERSGOVT ACTION EXPECTATIONS http://www.yout ube.com/watch ?feature=endscr een&v=pt0rdKr hN1w&NR=1

13. Input Costs   Input costs are the price of the resources needed to produce a good or provide a service.   Cheaper costs = more goods supplied   Example   The cost of corn and oil go up resulting in less gas being produced.

14. Cost of production goes down Cost of production goes up

15. Technology   Technology is when one applies scientific methods and innovations to production.   Better tech enables companies to produce more goods.   Examples   Tractors allow farmers to grow more food.   Computers allow more work to be processed than typewriters.

16. Better technologyTechnology shutdown

17. Government Action   Government policies can either help or hurt costs of production.   Excise Tax, Regulations and…   Subsidies: payments that help to cover some costs, encourage companies to produce a certain good.   Examples   Tax on cigarettes, A subsidy for milk, The Clean Air Act

18. Subsidy for goodIncreased tax on good

19. Number of Producers   If a company is successful, other companies will try to copy that success.   With more producers, more goods or serviced are produced.   Examples:   Many car companies exist due to the success of Ford.   Increased competition drove out Pontiac and Saturn.

20. New company joins industry Company drops out of industry

21. Producer Expectations   If producers expect the price of their product to rise or fall in the future, that may affect their rate of production.   If expecting higher selling prices, Sony may choose to produce more PS4s now.

22. Producer expects price of good to rise Producer expects price of good to fall

23. Labor Productivity   Labor Productivity refers to the amount of goods and services that a person can produce at a given time.   Increased productivity means more goods can be sold.

24. New training methodLoss of workers

25. Elasticity of Supply   Elasticity of supply is how responsive producers are to price changes.   Elastic supply – quantity supplied will change greatly as price changes.   Inelastic supply – quantity supplied will change little as price changes.

26. Elastic Supply 0 Quantity Price 10 20 40 60 30 5 15 20 10 25 30 When supply is elastic, prices will not change much, but quantity supplied will change. A B C D E F 50

27. Inelastic Supply 0 Quantity Price 10 20 4050 30 5 15 20 10 25 30 A B C D E F When supply is in elastic, prices will change a lot, but quantity supplied will not change much.

28. Factor of Supply Elasticity   The only factor of elasticity for supply is the ease of changing production when the price of an item changes.   Bigger companies are inelastic in the short run as it takes time to adjust production.
