The interaction of individual choices

Individuals living in the state of Kansas like to consume both soybeans and blueberries. While it is possible for farmers to grow both crops in Kansas, almost no farmers elect to use their land to grow blueberries. Instead, every year, Kansas exports soybeans and imports blueberries from nearby Michigan, where growers specialize in blueberries.

5. Changes in incentives

Suppose that a large influx of electric scooter rentals in a crowded downtown area results in a lot of new riders on the streets. For their safety, the mayor of the city decides to enact a law requiring helmets when renting scooters. These new helmets reportedly decrease the probability of injury by 29% in the event of a scooter crash.
While the new helmets    the probability of injury resulting from a scooter accident, they also incentivize individuals to ride    recklessly, which could    the number of scooter collisions and therefore injuries to renters.

Suppose that Eric is a diligent hard-working fourth-year college student. One Friday, he decides to start the day by working through 150 practice problems to study for the econometrics class. Using a table to track his progress throughout the day, he notices that as the hours pass, it takes him longer to solve the problems.
TimeTotal Problems Solved
7:00 AM0
8:00 AM60
9:00 AM105
10:00 AM135
11:00 AM150
Use the table to answer the following questions.
a) The marginal, or additional, gain from Alivia’s second hour spent working, from 8:00 AM to 9:00 AM, is _ problems
b) The marginal gain from Alivia’s fourth hour spent working, from 10:00 AM to 11:00 AM, is problems
Question 2
The following week, Alivia’s econometrics faculty advisor gives her some advice. In all their years of teaching they claim to observe that working on 22.5 multiple choice questions boosts a student’s test score by about the same amount as spending an hour reviewing lecture notes. For simplicity, assume students are able to review lecture notes at a constant pace during each hour spent studying.
Given this information, in order to use her 4 hours of time spent studying to get the highest possible test score, how many hours should she have spent solving multiple choice problems, and how many hours should she have spent reviewing lecture notes?
Correct

a) 45 problemsb) 15 problemsExplanationsBy 8:00 AM, Alivia has answered 60 problems. By 9:00 AM, Alivia has answered 105 problems. So the marginal, or additional, gain from her work between 8:00 AM and 9:00 AM is 105−60=45105−60=45 problems.By 10:00 AM, Alivia has answered 135 problems. By...

Suppose that Juanita is deciding whether or not to buy a pair of sandals that she has been researching online, and also the best place to make her purchase. Three different stores in the area sell the sandals she likes, but some stores are more convenient for Juanita 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 $112 for the sandals:

StoreTravel Time Each WayPrice of a Sandals
(Minutes)(Dollars per sandals)
Local Shoe Store15112
Different Neighborhood in Town3098
Rural Outlet6086
Juanita earns an hourly wage of $42 at her job. In order to purchase her sandals she will have to take time off work, so each hour away from her job costs her $42 in lost income. Assume that Juanita’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 that Juanita incurs no additional costs other than the sandals, such as gas.


Complete the following table by computing the opportunity cost of Juanita's time and the total cost of shopping at each location.StoreOpportunity Cost of TimePrice of a SandalsTotal Cost(Dollars)(Dollars per sandals)(Dollars)Local Shoe Store42.00112154.00Different Neighborhood in Town63.0098161.00Ru...
