Question 30
Link and Zelda each have 12 hours a week they can spend making costumes and accessories for their cosplay group. Link has been doing this for years and can make a costume piece in 2 hours and an accessory item in 1 hour. Zelda is still learning and can make a costume piece in 3 hours and an accessory item in 2 hours.
The opportunity cost of 1 costume piece for Link in terms of accessory items (i.e. accessory items per costume piece):
Assume two moms live next to each other and both have one preschooler. They meet each other for the first time and discover that both of them work part-time twice a week. It turns out that both of them have their children attend a child care facility close to home. Furthermore, they each learn that when one mom is working the other is at home and vice versa. One of the moms has an idea and proposes to the other mom that each take care of the other's child while they work. That way they can save money on child care. If they do this, what will happen to the official GDP reported by the government and why? Is society necessarily worse off as a result of this arrangement?
Suppose that Ciana is deciding whether or not to buy a pair of sneakers that she has been researching online, and also the best place to make her purchase. Three different stores in the area sell the sneakers she likes, but some stores are more convenient for Ciana to reach than others. One option is her local shoe store located only 15 minutes away from where she works, where they charge a marked-up price of $124 for the sneakers:

Ciana earns an hourly wage of $30 at her job. In order to purchase her sneakers she will have to take time off work, so each hour away from her job costs her $30 in lost income. Assume that Ciana’s travel time is the same each way (to and from the store) and that it will take her 30 minutes once she reaches a store to complete her shopping. Assume throughout the question…

- Suppose that there are three beachfront parcels of land available for sale in Astoria, and six people who would each like to purchase one parcel. Assume that the parcels are essentially identical and that the selling price of each is $745,000. The following table states each person's willingness and ability to purchase a parcel.

His opportunity cost of producing a second train per day is _________ per day. Now, suppose Yakov is currently using combination C, producing two trains per day. His opportunity cost of producing a third train per day is ________ per day. From the previous analysis, you can determine that as Yakov increases his production of trains, his opportunity cost of producing one more train increases or decreases? . Suppose Yakov buys a new tool that enables him to produce twice as many trains per hour as before, but it doesn't affect his ability to produce balls. Use the green points (triangle symbol) to plot his new PPF on the previous graph. Because he can now make more trains per hour, Yakov's opportunity cost of producing balls is higher than/lower than or stays same it was previously.arrow_forwardUse the following table to answer the question below.

- AFTER THE CHART Suppose Frances is currently using combination D, producing one truck per day. Her opportunity cost of producing a second truck per day is per day. Now, suppose Frances is currently using combination C, producing two trucks per day. Her opportunity cost of producing a third truck per day is per day. From the previous analysis, you can determine that as Frances increases her production of trucks, her opportunity cost of producing one more truck . Suppose Frances buys a new tool that enables her to produce twice as many trucks per hour as before, but it doesn't affect her ability to produce puzzles. Use the green points (triangle symbol) to plot her new PPF on the previous graph. Because she can now make more trucks per hour, Frances's opportunity cost of producing puzzles is it was previously.arrow_forwardTwo men, Robinson Crusoe and Friday, have been marooned separately on the same deserted island. There are two activities each man can undertake to obtain food: fishing and gathering coconuts. Robinson Crusoe can catch 40 fish per hour or gather 10 coconuts per hour. Friday can catch 10 fish per hour or gather 8 coconuts per hour. Answer the following questions: A. Who is more efficient in each activity? Could either or both of them benefit from meeting and deciding to form a trading relationship? Explain intuitively. B. Robinson and Friday have not yet met. Robinson is working 2 hours a day and producing (and consuming) 48 fish and 8 coconuts (note: the fish are very small). Friday is also working 2 hours a day, but he is producing and consuming 15 fish and 4 coconuts. Now assume that Robinson and Friday meet and develop a trading relationship. Come up with a production and trading scheme such that they can each work the same amount per day as before, but each is better off…arrow_forwardFor the three-part question that follows, provide your answer to each question in the given workspace.
