1. 1 Supply SECTION 1: Nature of Supply SECTION 2: Changes in Supply SECTION 3: Making Production Decisions CHAPTER 4

2. 2 Difference between supply and quantity supplied: supply—quantity of goods and services that producers are willing and able to offer at various prices during a given time period quantity supplied—the amount of a good or service that producers are willing to supply at each particular price Nature of Supply SECTION 1

3. 3 Law of supply: More goods and services are supplied when they can be sold at higher prices, and fewer goods and services are supplied when they must be sold at lower prices. Nature of Supply SECTION 1

4. 4 Supply schedule—the quantity of a product that a producer is willing to supply at various prices

5. 5 Table 4-4: Ben’s Supply Schedule 53.00 42.50 32.00 21.50 11.00 00.50 00.00 Quantity of cones Supplied Price of Ice-cream Cone ($)

6. 6 Supply curve graphs the data shown in supply schedules indicates a product’s market over a specific period of time

7. 7 Price of Ice- Cream Cone Quantity of Ice-Cream Cones 681012 0 2 1.50 1.00 1 2.00 3 4 $3.00 2.50 5 0.50 Figure 4-5: Ben’s Supply Curve

8. 8 Supply elasticity indicates the extent to which price changes affect the quantity supplied. Nature of Supply SECTION 1

9. 9 Price of Ice- Cream Cone Quantity of Ice-Cream Cones S3S3 S2S2 S1S1 Decrease in supply Increase in supply Figure 4-7: Shifts in the Supply Curve

10. 10 When a product’s supply shifts, different quantities of products are supplied at every possible price. Changes in Supply SECTION 2

11. 11 Determinants of product supply shifts: resource prices government tools technology competition prices of related goods producer expectations Changes in Supply SECTION 2

12. 12 Difference between a tax and a subsidy: tax—required payment to the government subsidy—payment to private businesses by the government Changes in Supply SECTION 2

13. 13 Objectives: Why do producers look at productivity when making supply decisions? How do varying levels of input affect the levels of output? How do changes in production costs affect producers’ supply decisions? Making Production Decisions SECTION 3

14. 14 Why producers look at productivity when making supply decisions: to determine how efficiently their resources are being used in production to maximize efficiency to increase profits Making Production Decisions SECTION 3

15. 15 How varying levels of input affects the levels of output: Adding levels of input increases productivity up to a point and then eventually results in decreased productivity and in negative marginal product. Making Production Decisions SECTION 3

16. 16 How changes in production costs affect producers’ supply decisions: by determining the prices at which producers supply quantities of goods or services by determining production goals Making Production Decisions SECTION 3

17. 17 1. 1.Define the law of supply. Be sure to include how the profit motive relates to this law. 2. 2.What causes movement along a supply curve—in other words, what prompts a change in the quantity supplied? How does this movement differ from a shift in supply? 3. 3.What determinants can cause a shift in supply? Give examples of at least three of these factors at work for a company that manufactures televisions. Wrap-Up CHAPTER 4

18. 18 4. 4.In how many ways does new technology affect the supply curve? Give at least one example for each way you come up with. 5. 5.Explain what happens in the three stages of production described by the law of diminishing returns. 6. 6.Explain the difference among the following types of costs: fixed, variable, total, marginal.
