There is [Select] by the market that is equal to [Select] units of potato chips. c) Suppose that Pete decides to go on a diet and will no longer purchases potato chips at any price. In addition, after Pete has left the market, suppose that we observe that the quantity of potato chips demanded by the market is equal to 14 units. We can therefore infer that the market price is [Select]arrow_forwardWhat is the shape of the marginal utility curve?arrow_forward

- Briefly discuss four disadvantages of using Cost-benefit analysis to measure utility.arrow_forwardRead the following passage that describes why some consumers clip coupons while others don't. Then answer the question that follows. V THE ECONOMIC RATIONALE BEHIND COUPON CLIPPING, BY THE APLIA ECONOMICS CONTENT TEAM If coupon clipping is so rewarding, why doesn't everyone do it? According to basic economic theory, the number one reason is that coupon clipping isn't actually free. Sure, it doesn't explicitly cost you money out of your pocket, but it does cost you time to scan newspapers, magazines, and the Internet for savings that sometimes seem insignificant. Economists refer to this as the opportunity cost of clipping coupons. For example, an hour spent clipping coupons means an hour less to spend earning income, enjoying leisure time, or sleeping. For those who have fewer high-value alternatives competing for their time, such as stay-at-home parents or retired senior citizens, coupon clipping may be time well spent.

- What is Marginal Utility, what is the concept of diminishing marginal utility?arrow_forwardSuppose that Biff enters a hot dog eating contest. He enjoys hot dogs, so he gladly pays the $20 entry fee. Biff realizes there is very little chance that he will actually win the contest. He just likes the idea of being able to eat all the hot dogs he wants. The table below shows Biff’s utility from eating hot dogs.    a. Use the table below and fill in the values for marginal utility.  Hot Dogs and Biff's Utility Hot Dogs Total Utility (utils) Marginal Utility (utils) 5 48 — 6 52  7 54  8 55  9 54  10 51   b. Use the table to graph Biff's total utility and marginal utility for hot dogs.         c. If Biff is rational, and has no intention of winning the hot dog eating contest, what is the optimal number of hot dogs he will eat? What is the maximum level of utility Biff can reach from eating that number of hot dogs?      Optimal number of hot dogs:      Maximum utility:arrow_forwardQ. 4 Economists suggest that common people consciously equate marginal utility with price as they are shopping for groceries, but I don't think anyone else but economists may do this and I suspect even they slip up. It is ridiculous to describe consumer behavior in terms of a theory that consumers have never even heard of. Humans are not super calculators. Many times people buy things on a whim. For example, I buy chewing gum at the checkout counter and it is not on my original list of items to purchase. Discuss Is the Homo Economicus assumption, that is, humans have the super-cognitive ability, are super-rational, and possess full information of all relevant costs, tradeoffs, budget available, and consequences, a reasonable assumption, or is there some other psychological model of consumer behavior that seem s more reasonable and explain observed human behavior well.arrow_forward
