3. Chapter Intro 1 In order to earn some extra money, you are considering opening a lawn or babysitting service. Brainstorm the resources you would need. What specific services would you offer? What prices would you charge? What information do you need to determine answers to these and other questions? Read Chapter 5 to find out about the factors that influence how businesses make production decisions.

4. Chapter Intro 2 1.Buyers and sellers voluntarily interact in markets, and market prices are set by the interaction of demand and supply. 2.The profit motive acts as an incentive for people to produce and sell goods and services.

8. Section 1 Supply is an amount of product offered for sale at prevailing market prices.Supply Law of Supply: Producers will offer more product at higher prices and less at lower pricesLaw of Supply What is Supply?

9. Section 1 An Introduction to Supply Supply can be illustrated by a supply schedule or a supply curve.

10. Section 1 An Introduction to Supply (cont.) Suppliers must determine how much to offer for sale at various prices, taking into account the factors of production. Like demand, supply can be shown in the form of a table—a supply schedule.supply schedule When information is plotted on a graph, it forms the supply curve.supply curve Supply of Compact Discs

11. Section 1 An Introduction to Supply (cont.) Normal supply curves have a positive slope—prices go up; quantity supply goes up. Economists are more interested in the market supply curve than for a single firm.market supply curve Individual and Market Supply Curves

12. Section 1 An Introduction to Supply (cont.) The quantity supplied is the amount producers bring to market at any given price.quantity supplied A change in price leads to a change in quantity supplied.change in quantity supplied Although the producer has the freedom to adjust production up or down, the interaction of supply and demand usually determines the final price of a product.

13. Section 1 Change in Supply Several factors can contribute to a change in supply.

14. Section 1 A change in supply occurs for several reasons.change in supply –Cost of resources –Productivity –Technology –Taxes Change in Supply (cont.) A Change in Supply

15. Section 1 –SubsidySubsidy –Expectations –Government regulations –Number of sellers Change in Supply (cont.)

16. Section 1 Elasticity of Supply The response to a change in price varies for different products.

17. Section 1 Supply, like demand, has elasticity. Supply elasticity measures how the quantity supplied responds to a change in price.Supply elasticity Elasticity of Supply (cont.) Elasticity of Supply

18. Section 1 Supply elasticity has three forms: –Elastic –Inelastic –Unit elastic Elasticity of Supply (cont.) Elasticity of Supply

19. Section 1 Supply elasticity is based solely on production considerations. A firm’s ability to adjust to new prices quickly is likely to be elastic. A firm that takes longer to react to a change in prices is likely to be inelastic. Elasticity of Supply (cont.) Elasticity of Supply

21. Section 2-Preview Section Preview In this section, you will learn how a change in the variable input called “labor” results in changes in output.

23. Section 2 The Production Function The production function shows how output changes when a variable input such as labor changes.

24. Section 2 The Production Function (cont.) Production can be illustrated with a production function. production function Economists focus on the short run when they analyze production.short run No changes occur in land, equipment, or technology. Changes in total product are caused by a change in the number of workers.total product Short-Run Production

25. Section 2 The Production Function (cont.) Long run changes involve other factors of production, including capital.Long run Marginal product—the extra output or change in total product caused by adding one more unit of variable inputMarginal product

26. Section 2 Stages of Production The stages of production help companies determine the most profitable number of workers to hire.

27. Section 2 In deciding how many workers to hire, firm must review the three stages of production.stages of production –Increasing returns, Stage I –Diminishing returns, Stage IIDiminishing returns –Negative returns, Stage III Stages of Production (cont.)

29. Section 3-Preview Section Preview In this section, you will learn how businesses analyze their costs and revenues, which helps them maximize their profits.

31. Section 3 Measures of Cost Businesses analyze fixed, variable, total, and marginal costs to make production decisions.

32. Section 3 Measures of Cost (cont.) There are several ways businesses measure costs. –Fixed costsFixed costs Total fixed costs, sometimes called overhead, remain the same. overhead –Variable costsVariable costs

33. Section 3 Measures of Cost (cont.) –Total costTotal cost –Marginal costMarginal cost Production, Costs, and Revenues

34. Section 3 Applying Cost Principles Fixed and variable costs affect the way a business operates.

35. Section 3 People engage in e-commerce conducted on the Internet becausee-commerce –Overhead costs are low. –There is a low need for inventory. Applying Cost Principles (cont.)

36. Section 3 After businesses measure their costs, they determine the break-even point.break-even point Businesses wanting to do better than break even apply principles of marginal analysis to their costs and revenues. Applying Cost Principles (cont.)

37. Section 3 Marginal Analysis and Profit Maximization Businesses compare marginal revenue with marginal cost to find the level of production that maximizes profits.

38. Section 3 Two key measures of revenue are used to find the amount of output that will produce the greatest profits: –Total revenueTotal revenue –Marginal revenueMarginal revenue Marginal Analysis and Profit Maximization (cont.) The Global Economy & YOU Air & Ground Shipping Market

39. Section 3 Like businesses, we use marginal analysis in our own decision making.marginal analysis When marginal cost is less than marginal revenue, hire more variable inputs (labor) to expand output. Marginal Analysis and Profit Maximization (cont.)

40. Section 3 Profit-maximizing quantity of output is reached when marginal cost and marginal revenue are equal.Profit-maximizing quantity of output Marginal Analysis and Profit Maximization (cont.)

41. Section 3-End

42. Law of Supply When the price of a product goes up, quantity supplied goes up. When the price goes down, quantity supplied goes down. VS 1

43. VS 2 Production Function The production function helps us find the optimal number of variable units (labor) to be used in production. As workers are added in Stage I, production increases at an increasing rate. In Stage II, production increases at a decreasing rate because of diminishing returns. In Stage III, production decreases because more workers cannot make a positive contribution.

44. VS 3 Cost and Revenue While businesses have several types of costs, they can find the profit-maximizing quantity of output by comparing marginal cost to their marginal revenue.
