Suppose Coke and Pepsi are perfect substitutes for me, and right and left shoes are perfect complements.
A. Suppose my income allocated to Coke/Pepsi consumption is $100 per month, and my income allocated to right/left shoe consumption is similarly $100 per month.
a. Suppose Coke currently costs $0.50 per can and Pepsi costs $0.75 per can. Then the price of Coke goes up to $1 per can. Illustrate my original and my new optimal bundle with "Coke" on the horizontal and "Pepsi" on the vertical axis.
b. Suppose right and left shoes are sold separately. If right and left shoes are originally both priced at $1, illustrate (on a graph with "right shoes" on the horizontal and "left shoes" on the vertical) my original and my new optimal bundle when the price of left shoes increases to $2.
c. True or False: Perfect complements represent a unique special case of homothetic tastes in the following sense: Whether income goes up or whether the price of one of the goods falls, the optimal bundle…
It is common for supermarkets to carry both generic (store-label) and brand-name (producer-label) varieties of sugar and other products. Many consumers view these products as perfect substitutes, meaning that consumers are always willing to substitute a constant proportion of the store brand for the producer brand. Consider a consumer who is always willing to substitute 4 pounds of a generic store brand for 2 pounds of a brand-name sugar. Do these preferences exhibit a diminishing marginal rate of substitution? Assume that this consumer has $24 of income to spend on sugar, and the price of store-brand sugar is $1 per pound and the price of producer-brand sugar is $3 per pound. How much of each type of sugar will be purchased? How would your answer change if the price of store-brand sugar was $2 per pound and the price of producer-brand sugar was $3 per pound?
Bart and Lisa are both optimizing consumers in themarkets for shirts and hats, where they pay $100for a shirt and $50 for a hat. Bart buys 8 shirts and4 hats, while Lisa buys 6 shirts and 12 hats. Fromthis information, we can infer that Bart’s marginalrate of substitution is _________ hats per shirt, whileLisa’s is _________.a. 2; 1b. 2; 2c. 4; 1d. 4; 2

- The following graph shows Hilary's weekly demand for cheesecake, represented by the blue line. Point A represents a point along her weekly demand curve. The market price of cheesecake is $3.00 per slice, as shown by the horizontal black line From the previous graph, you can tell that Hilary is willing to pay $_______ for her 8th slice of cheesecake each week. Because she has to pay only$3.00 per slice, the consumer surplus she gains from the 8th slice of cheesecake is $_______. Suppose the price of cheesecake were to fall to $2.25 per slice. At this lower price, Hilary would receive a consumer surplus of $_______.from the 8th slice of cheesecake she buys.The following graph shows the weekly market demand for cheesecake in a small economy. Use the purple point (diamond symbol) to shade the area representing consumer surplus when the price (P) of cheesecake is $3.00 per slice.

- Bob lives in San Diego and loves to eat desserts. He spends his entire weekly allowance on pudding and pie. A bowl of pudding is priced at $1.00, and a piece of apple pie is priced at $4.00. At his current consumption point, Bob's marginal rate of substitution (MRS) of pudding for pie is 4. This means that Bob is willing to trade four bowls of pudding per week for one piece of pie per week. Does Bob's current bundle maximize his utility—in other words, make him as well off as possible? If not, how should he change it to maximize his utility? Bob could increase his utility by buying more pudding and less pie per week. Bob's current bundle maximizes his utility, and he should keep it unchanged. Bob could increase his utility by buying less pudding and more pie per week.arrow_forwardQuestion 3 Maureen spends her budget on pizza and salad.

Suburbs makes $200 a week at her summer job and spends her entire weekly income on new running shoes and designer jeans, because these are the only two items that provide utility to her. Furthermore, Elizabeth insists that for every pair of jeans she buys, she must also buy a pair of shoes (without the shoes, the new jeans are worthless). Therefore, she buys the same number of pairs of shoes and jeans in any given week. a. If jeans cost $20 and shoes cost $20, how many will Elizabeth buy of each? b. Suppose that the price of jeans raises to $30 a pair. How many shoes and jeans will she buy? c. Show your results by graphing the budget constraints from part a and part b.

- 7. MRS and utility maximization Suppose your classmate Eleanor loves to eat dessert-so much so that she allocates her entire weekly budget to apple crisp and pie. The price of one bowl of apple crisp is $1.00, and the price of a piece of rhubarb pie is $3.00. At her current level of consumption, Eleanor's marginal rate of substitution (MRS) of apple crisp for pie is 3. In other words, Eleanor is willing to sacrifice three bowls of apple crisp for one piece of pie per week. Does Eleanor's current consumption bundle maximize her utility? That is, does it make her as well off as possible? If not, how should she change it to maximize her utility? Eleanor could increase her utility by buying more apple crisp and less pie per week. O Eleanor's current bundle maximizes her utility, and she should keep it unchanged. O Eleanor could increase her utility by buying less apple crisp and more pie per week.arrow_forward5. Complements and substitutes Jake enjoys eating peanut butter sandwiches and drinking soda. He is particular about proportions, though: For every peanut butter sandwich he eats, he must drink exactly one glass of sods, and vice versa. Jake can purchase the peanut butter for his sandwiches in two jar sizes: 20 ounces and 40 ounces. Jake cares only about the total amount of peanut butter he has available and not at all about the jar size. In other words, he's just as happy with two 20-ounce jars as he is with one 40-ounce jar. In this scenario, peanut butter sandwiches and glasses of soda are Two possible bundles of peanut butter sandwiches and glasses of sods are shown on the following graph, labeled A and B. Using three purple points (diamond symbol), plot Jake's indifference curve that passes through point A (1₁). Then, using three orange points (square symbol), plot Jake's indifference curve that passes through point B (1₂).
