12. 11 Section 1-4 People sometimes think of demand as the desire to have or to own a certain product.  In this sense, anyone who would like to own a swimming pool could be said to “demand” one.  Click the mouse button or press the Space Bar to display the information. Introduction In order for demand to be counted in the marketplace, however, desire is not enough; it must coincide with the ability and willingness to pay for it.

13. 12 Section 1-5 Only those people with demand—the desire, ability, and willingness to buy a product-can compete with others who have similar demands.  Introduction (cont.) Demand, like many other topics in Unit 2 is a microeconomic concept.  Microeconomics is the area of economics that deals with behavior and decision making by small units, such as individuals and firms.

14. 13 Section 1-5 Introduction (cont.) Collectively, these concepts of microeconomics help explain how prices are determined and how individual economic decisions are made.

15. 14 Section 1-6 Click the mouse button or press the Space Bar to display the information. Demand is the desire, ability, and willingness to buy a product.  An individual demand curve illustrates how the quantity that a person will demand varies depending on the price of a good or service.  An Introduction to Demand Economists analyze demand by listing prices and desired quantities in a demand schedule (chart). When the demand data is graphed, it forms a demand curve with a downward slope.

18. 17 Section 1-Assessment 1 Discussion Question Think about something you have been wanting to buy. What is its price? At what price would you be willing to buy the item? Answers will vary, but students should demonstrate an understanding of the concept of demand. Click the mouse button or press the Space Bar to display the answer.

19. 18 Section 1-11 Click the mouse button or press the Space Bar to display the information. The Law of Demand states that the quantity demanded of a good or service varies inversely with its price. When price goes up, the quantity demanded goes down; when price goes down, the quantity demanded goes up.  The Law of Demand A market demand curve illustrates how the quantity that all interested persons (the market) will demand varies depending on the price of a good or service.

20. 19 Section 1-Assessment 1 Discussion Question Why is price a consumer’s obstacle to buying? Answers will vary, but may include that a consumer’s money is limited, and the price of a product forces the consumer to determine how much his or her demand is for the product. Click the mouse button or press the Space Bar to display the answer.

21. 20 Section 1-15 Click the mouse button or press the Space Bar to display the information. Marginal utility is the extra usefulness or satisfaction a person receives from getting or using one more unit of a product.  Demand and Marginal Utility The principle of diminishing marginal utility states that the satisfaction we gain from buying a product lessens as we buy more of the same product.

22. 21 Section 1-Assessment 1 Discussion Question You have read about buying a cola as an example of diminishing marginal utility. What is another case in which more product gives less satisfaction? Answers will vary, but students should demonstrate an understanding of the concept of diminishing marginal utility. Click the mouse button or press the Space Bar to display the answer.

23. 22 Section 1-Assessment 1 Section Assessment Main Idea Using your notes from the graphic organizer activity on page 89, write a definition of demand in your own words. Answers should include the desire, ability, and willingness to buy a product. Click the mouse button or press the Space Bar to display the answer.

24. 23 Section 1-Assessment 2 Section Assessment (cont.) Describe the relationship between the demand schedule and demand curve. Both provide information about demand–the schedule in the form of a table and the curve in the form of a graph. Click the mouse button or press the Space Bar to display the answer.

25. 24 Section 1-Assessment 3 Section Assessment (cont.) Describe how the slope of the demand curve can be explained by the principle of diminishing marginal utility. Diminishing marginal utility says that as we use more of a product, we are not willing to pay as much for it. Therefore, the demand curve is downward sloping. People will not pay as much for the second and third product as they will for the first. Click the mouse button or press the Space Bar to display the answer.

26. 25 Section 1-Assessment 5 Section Assessment (cont.) Using Graphs Create your own demand schedule for an item you currently purchase. Next, plot your demand schedule on a demand curve.

32. 31 Section 2-4 The demand curve is a graphical representation of the quantities that people are willing to purchase at all possible prices that might prevail in the market.  Occasionally something happens to change people’s willingness and ability to buy.  These changes are usually of two types: a change in the quantity demanded, and a change in demand. Click the mouse button or press the Space Bar to display the information. Introduction

33. 32 Section 2-4 In 1983, the first audio compact discs were introduce to U.S. consumers. Within five years, record companies had begun to phase out the vinyl albums on which music was traditionally played because sales figures had shown that consumers preferred CD technology. Click the mouse button or press the Space Bar to display the information. Did You Know?

34. 33 Section 2-5 Click the mouse button or press the Space Bar to display the information. The change in quantity demanded shows a change in the amount of the product purchased when there is a change in price.  The income effect means that as prices drop, consumers are left with extra real income.  Change in Quantity Demanded The substitution effect means that price can cause consumers to substitute one product with another similar but cheaper item.

Students should explain how their responses illustrate the income effect. Click the mouse button or press the Space Bar to display the answer.

37. 36 Section 2-9 Click the mouse button or press the Space Bar to display the information. A change in demand can be caused by a change in income, tastes, a price change in a related product (either because it is a substitute or complement), consumer expectations, and the number of buyers. A change in demand is when people buy different amounts of the product at the same prices.  Change in Demand

39. 38 Section 2-Assessment 1 Discussion Question Although CDs are by far today’s most popular form of musical recording, interest in “vinyls” (the word people now use to refer to the old vinyl albums) is growing. What might happen to the demand for vinyls as interest increases? Students should indicate that increased interest probably will lead to an increase in demand for vinyls. Click the mouse button or press the Space Bar to display the answer.

40. 39 Section 2-Assessment 1 Section Assessment Main Idea How does the income effect explain the change in quantity demanded that takes place when the price goes down? Because of the decrease in price, consumers have more real income, leading to an increase in the quantity demanded of a product. Click the mouse button or press the Space Bar to display the answer.

41. 40 Section 2-Assessment 2 Section Assessment Describe the difference between a change in quantity demanded and a change in demand. A change in quantity demanded reflects a change in the quantity of the product purchased in response to a change in price. A change in demand reflects a willingness to buy different amounts of the product at the same price. Click the mouse button or press the Space Bar to display the answer.

42. 41 Section 2-Assessment 3 Section Assessment (cont.) Explain how a change in price affects the demand for a product’s substitute(s). The demand for a product tends to increase if the price of its substitutes goes up, and vice versa. Click the mouse button or press the Space Bar to display the answer.

43. 42 Section 2-Assessment 5 Section Assessment (cont.) Understanding Cause and Effect What happens to the price and the quantity of goods and services sold when a store runs a sale? How do these factors relate to the downward- sloping curve? A reduction in prices during a sale leads to an increase in quantity of products sold. The downward slope of the demand curve reflects these trends as prices decrease and quantity increases. Click the mouse button or press the Space Bar to display the answer.

49. 48 Section 3-4 Cause-and-effect relationships are important in the study of economics.  An important cause-and-effect relationship in economics is elasticity, a measure of responsiveness that tells us how a dependent variable such as quantity responds to a change in an independent variable such as price. Click the mouse button or press the Space Bar to display the information. Introduction For example, we often ask, “if one thing happens, how will it affect something else?” 

50. 49 Section 3-4 Elasticity is also a very general concept that can be applied to income, the quantity of a product supplied by a firm, or to demand. Click the mouse button or press the Space Bar to display the information. Introduction (cont.)

51. 50 Section 3-4 The drugs needed to get or stay well can take a large portion of a consumer’s income, especially if that income is fixed. However, the use of generic drugs had offered consumers a cheaper alternative to drugs with brand names.

Did You Know?

52. 51 Section 3-5 Click the mouse button or press the Space Bar to display the information. Elasticity measures how sensitive consumers are to price changes.  Demand is elastic when a change in price causes a large change in demand.  Demand Elasticity Demand is inelastic when a change in price causes a small change in demand.  Demand is unit elastic when a change in price causes a proportional change in demand.

53. 52 Section 3-Assessment 1 Discussion Question What are examples of items for which an increase in price would cause you or your family to reconsider buying them? Answers will vary but should illustrate an understanding of price elastic demand. Click the mouse button or press the Space Bar to display the answer.

54. 53 Section 3-9 Click the mouse button or press the Space Bar to display the information. Price times quantity demanded equals total expenditures.  Changes in expenditures depend on the elasticity of a demand curve—if the change in price and expenditures move in opposite directions on the curve, the demand is elastic, if they move in the same direction, the demand is inelastic; if there is no change in expenditures, demand is unit elastic.  The Total Expenditures Test Understanding the relationship between elasticity and profits can help producers effectively price their products.

55. Section 3-9 The Total Expenditures Test (cont.)

56. 55 Section 3-Assessment 1 Discussion Question What are examples of items for which a drop in price would not encourage you to buy more of an item?

57. 56 Section 3-14 Click the mouse button or press the Space Bar to display the information. Demand is elastic if the answer to the following questions are “yes”.  Determinants of Demand Elasticity –Can the purchase be delayed? Some purchases cannot be delayed, regardless of price changes.  –Are adequate substitutes available? Price changes can cause consumers to substitute on product for a similar product.  –Does the purchase use a large portion of income? Demand elasticity can increase when a product commands a large portion of a consumer’s income.

67. 66 Chapter Summary 1 Section 1: What Is Demand? Click the mouse button or press the Space Bar to display the information. Microeconomics is the area of economic study that deals with individual units in an economy, such as households, business firms, labor unions, and workers.  You express demand for a product when you are both willing and able to purchase it.  Demand can be summarized in a demand schedule, which shows the various quantities that would be purchased at all possible prices that might prevail in the market.  Demand can also be shown graphically as a downward sloping demand curve.

68. 67 Chapter Summary 2 Click the mouse button or press the Space Bar to display the information. Section 1: What Is Demand? (cont.) The Law of Demand refers to the inverse relationship between price and quantity demanded.  Individual demand curves for a particular product can be added up to get the market demand curve.  Marginal utility is the amount of satisfaction an individual receives from consuming one additional unit of a particular good or service.  Diminishing marginal utility means that with each succeeding unit, satisfaction decreases.

69. 68 Chapter Summary 3 Click the mouse button or press the Space Bar to display the information. Section 2: Factors Affecting Demand Demand can change in two ways–a change in quantity demanded or a change in demand.  A change in quantity demanded means people buy a different quantity of a product if that product’s price changes, appearing as a movement along the demand curve.  A change in demand means that people have changed their minds about the amount they would buy at each and every price. It is represented as a shift of the demand curve to the right or left.  A change in consumer incomes, tastes and expectations, and the price of related goods causes a change in demand.

70. 69 Chapter Summary 4 Click the mouse button or press the Space Bar to display the information. Section 2: Factors Affecting Demand (cont.) Related goods include substitutes and complements. A substitute is a product that is interchangeable in use with another product. A complement is a product that is used in conjunction with another product.  The market demand curve changes whenever consumers enter or leave the market, or whenever an individual’s demand curve changes.

71. 70 Chapter Summary 5 Click the mouse button or press the Space Bar to display the information. Section 3: Elasticity of Demand Elasticity is a general measure of responsiveness that relates changes of a dependent variable such as quantity to changes in an independent variable such as price.  Demand elasticity relates changes in the quantity demanded to changes in price.  If a change in price causes a relatively larger change in the quantity demanded, demand is elastic.  If a change in price causes a relatively smaller change in the quantity demanded, demand is inelastic.

72. 71 Chapter Summary 6 Click the mouse button or press the Space Bar to display the information. Section 3: Elasticity of Demand (cont.) When demand is elastic, it stretches as price changes. Inelastic demand means that price changes have little impact on quantity demanded.  Demand is unit elastic if a change in price causes a proportional change in quantity demanded.  The total expenditures test can be used to estimate demand elasticity.  Demand elasticity is influenced by the ability to postpone a purchase, by the substitutes available, and by the proportion of income required for the purchase.

78. 77 Chapter Assessment 5 Click the mouse button or press the Space Bar to display the answer. Explain how the principle of diminishing marginal utility is related to the downward-sloping demand curve. Diminishing marginal utility states that as we use more of a product, we are not willing to pay as much for it. People will not pay as much for the second and third product as they did for the first, therefore the demand is downward sloping. Reviewing the Facts (cont.)

79. 78 Chapter Assessment 6 Click the mouse button or press the Space Bar to display the answer. Describe the difference between the income effect and the substitution effect. The income effect is the change in quantity demanded due to a change in price that alters consumers’ real income. The substitution effect is the change in quantity demanded due to the change in the relative price of the product. Reviewing the Facts (cont.)

80. 79 Chapter Assessment 7 Click the mouse button or press the Space Bar to display the answer. Identify the five factors that can cause a change in market demand. The five factors that can cause a change in market demand are: –consumer income –consumer tastes –substitutes and complements –change in expectations –number of consumers Reviewing the Facts (cont.)

81. 80 Chapter Assessment 8 Click the mouse button or press the Space Bar to display the answer. Describe the difference between elastic demand and inelastic demand. When demand is elastic, there is a relatively large change in quantity demanded when the price changes, giving the demand curve a flat slope. The change in quantity demanded is much smaller for inelastic demand, making the slope of the demand curve steeper. Reviewing the Facts (cont.)

82. 81 Chapter Assessment 9 Click the mouse button or press the Space Bar to display the answer. Explain how the total expenditures test can be used to determine demand elasticity. By observing the change in total expenditures when the price changes, you can determine demand elasticity. If expenditures and price move in opposite directions, demand is elastic, If they move in the same direction, demand is inelastic. If expenditures do not change, demand is unit elastic.

93. Infobyte 1 Housing Starts The number of housing starts shows the demand for new homes. Economists forecast housing starts by using the current month’s permits as a predictor. Building permits tend to move in tandem with starts on a month- to-month basis. They are also considered to be a leading indicator of the economy in general. Increases in building permits and starts are common during periods following a drop in mortgage rates.

98. Companies now sell college textbooks over the Internet. Universities enroll online and provide the required reading lists for their classes. Students can buy new and used textbooks from these lists, saving up to 40 percent on the cost of books. There is an economic incentive for colleges to use these Internet companies: the colleges receive a share in the revenue. Cybernomics 3.2

99. More About … Online Shopping E-commerce is finally becoming a popular method of shopping. Although there has been no significant change in the technology, sales over the Internet are increasing due to the confidence level of the consumer. In 1998, more than half of Web users had been online for over a year. More people are comfortable with navigating the Internet and using it for information. Cybernomics 3.3 Continued on next slide.

100. Other factors have led to increased usage of the Web for shopping. Safety features have improved, so there is diminishing fear of hackers stealing credit card numbers. Web sites are better, too, and are often interactive, colorful, and informative. Many people find that the Internet allows them to save money because it is convenient for quick price comparisons. Cybernomics 3.4
