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?
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…

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.

- 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_forwardWhy is it that this was wrong?

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. Also, draw Elizabeth’s indifference curves. d. To what effect (income or substitution) do you attribute the change in utility levels between part a and part b? e.
