Consumption and the Consumer Society Answer Key

CONSUMPTION AND THE CONSUMER SOCIETY Chapter Overview This chapter presents the standard economic model of consumer behavior. We explain the notion of consumer sovereignty, show how to graph a budget line, and explain the rule for utility maximization derived from marginal thinking. We set this standard material in context by then moving on to different perspectives on consumer behavior. First, we consider the historical context of consumer behavior. Then we consider the social and environmental contexts of modern consumer society. Finally, we explore the relationship between consumerism and well-being, and discuss options for public policy. Objectives After reading and reviewing this chapter, you should be able to: 1. 2. 3. 4. 5. 6. 7. Draw a budget line and a utility function. Discuss how marginal thinking can be used to maximize consumer utility. Discuss the historical and international contexts of consumer society. Explain the implications of the social context for consumer behavior. Describe the link between consumption and the environment. Evaluate the relationship between consumption and well-being. Discuss policy options for influencing consumer behavior.

The idea of consumer sovereignty holds that _____________________________ is the ultimate economic goal. 2. A group to which a consumer wishes he or she could belong to is a(n) ________________ group. 3. A ________________ line shows all the combinations of two goods that a consumer can purchase, given his or her monetary resources and the prices of the two goods. 4. The idea that a consumer’s additional utility from successive units of a good tends to decrease is known as ______________________________. 5. The feeling of lack that comes from comparing oneself with someone who has more is known as _________________________________. 6. Annual advertising expenditures in the United States are equivalent to $________ per person. 7. The practice of reducing one’s overall level of consumption in order to reduce their environmental impacts is referred to as ________________________________________. 8. A conscious decision to live with a limited or reduced level of consumption is known as _________________________________________________. True or False 9. About one third of the world’s population suffers from absolute deprivation. 10. Economic research has shown that one’s income level has no effect on one’s happiness. 11. Shallow green consumerism means a consumer will choose ecofriendly products, but not necessarily reduce his or her overall level of consumption. 12. Renee allocates her income between soup and nuts. If the price of soup increases while the price of nuts remains constant, Renee’s budget line will shift inward to a new, parallel budget line. 2 13. John allocates his income between bows and arrows. Suppose that a graph of his budget line shows quantity of bows on the horizontal axis and quantity of arrows on the vertical axis. If the price of bows decreases, John’s budget line pivots outward to a new line with a shallower slope. 14. According to the traditional model, consumers maximize utility by purchasing an equal amount of each good that provides utility. 15. Having aspirational groups tends to reduce people’s level of consumerism. Short Answer 16. Explain why a utility curve becomes flatter as consumption levels increase. __________________________________________________________________ __________________________________________________________________ __________________________________________________________________ __________________________________________________________________ __________________________________________________________________ 17.

Joel has $10 to spend on some combination of roses and daisies. Roses cost $1 each, and daisies cost $2 each. a. Draw Joel’s budget line, putting daisies on the vertical axis. b. If Joel buys four daisies, how many roses can he buy? 2. Continuing the example from above, now suppose that Joel’s income increases from $10 to $12. Sketch the budget line from Problem #1 and then show the change to the new budget line. 4 3. Continuing with the same example, suppose that Joel takes his $12 to the flower shop and discovers that someone else just bought almost all the roses and daisies in the shop. Only 4 roses and 2 daisies remain in the shop, so that’s all Joel can buy. a. Show this consumption combination on the graph. Does it fall to the left or right of the budget line? b. The next day, Joel goes back to the store with his $12 and this time there are plenty of roses and daisies available for purchase. However, the price of roses has increased to $2. Show the budget line before the price change, and then the resulting change in Joel’s budget line. 5 4. Jenny divides her income between corn and beans. She has a total of $100. Beans cost $10 per sack, and corn costs $20 per sack. a. Draw Jenny’s budget line, with beans on the vertical axis. b. The price of both beans and corn decreases by 50%, to $5 and $10 respectively.

True 10. False 11. False 12. False. Her budget line will rotate, not shift. 13. True 14. False 15. False 16. A utility curve becomes flatter as consumption levels increase because of diminishing marginal utility. Each successive unit of consumption provides a smaller increase in utility. Thus the utility curve rises by a smaller amount with each additional unit of consumption. 17. Absolute deprivation is an inability to meet basic needs. One –third of humanity suffers from absolute deprivation, most of them in developing countries. Relative deprivation is a feeling of lack that comes from comparing oneself to others who have more, and can occur even among those with relatively high incomes. 18. Higher income levels tend to be associated with higher subjective well-being, but at a decreasing rate. This is consistent with the idea of diminishing marginal utility. Research indicates that “emotional well-being” – focusing on the positive and negative emotions people experience n a daily basis – also increases with income, at a decreasing rate, but only up to a point. At an income level of $75,000, in the United States, further increases in income did not improve emotional well-being. 19. An indifference curve shows the combination of two goods with which a consumer would be equally satisfied. For example, a consumer might theoretically be equally satisfied with one ice cream cone and seven cookies, or with three cookies and two ice cream cones. 20. The shape of the indifference curve reflects the assumption that the consumer experiences diminishing marginal utility for both goods in question. 13 Answers to Problems 1. a.
