Suppose five people have houses on the same small lane. They all individually benefit from regular maintenance of the lane. Their individual marginal benefit curves are P = 8 ― (1/10)Q, where P reflects a willingness to pay in thousands and Q is the length of the road repaired in ten-yard units. The cost of maintenance is $2,000 per ten yards. Suppose one person is currently the only one paying for maintenance. How much does this person buy, and what is the deadweight loss? Does anyone individually have an incentive to pay for additional maintenance, and why or why not?
You are a professor of economics at a university. You've been offered the position of serving as department head, which comes with an annual salary that is $6,500 higher than your current salary. However, the position will require you to work 200 additional hours per year. Suppose the next best use of your time is spending it with your family, which has value of $20 per hour.
What is the difference in the net benefit from becoming the departmenthead?

A student has a part-time job in a restaurant. For this she is paid $8 per hour. Her utility function for earning $I and spending S hours studying is U(I,S) = I^1/4 S^3/4 (The utility function is a measure of the `usefulness' or `worth' to the student of a certain combination of money and study time). The total amount of time she spends each week working in the restaurant and studying is 100 hours. How should she divide up her time in order to maximise her utility?

- Suppose that before you began your college application process, you were offered a job to work as a floor-trainer at a local climbing gym, accompanied by a yearly salary of $30,000 (after taxes). Assume however that you decided to turn down this offer and instead attend a year of college. The total monetary cost of the year of college, including tuition, fees, and room and board expenses, is $42,000. You likely chose to attend college becausearrow_forwardYour classmates from the University of Chicago are planning to go to Miami for spring break, and you are undecided about whether you should go with them. The round-trip airfare is $600, but you have a frequent-flyer coupon worth $500 that you could use to pay part of the airfare. All other costs for the vacation are exactly $900. The most you would be willing to pay for the trip is $1,400. Your only alternative use for your frequent-flyer coupon is for your trip to Atlanta two weeks after the break to attend your sister's graduation, which your parents are forcing you to attend. The Chicago-Atlanta round-trip airfare is $450. If you do not use the frequent-flyer coupon to fly to Miami, should you go to Miami? Multiple Choice Yes, your benefit is more than your cost. No, your benefit is less than your cost. Yes, your benefit is equal to your cost. No, because there are no benefits in the trip.arrow_forwardYour Econ. Professor bought airline tickets to leave a conference early on Saturday morning. He later found out that he needed to present a paper later that Saturday, so he changed his tickets at a cost of $200. When he got to the conference, he discovered that he was scheduled twice: on Friday and on Saturday. He was given his choice of when to give the presentation. He said he would present on Saturday, because he paid an extra $200 in order to stay. Explain why you agree or disagree with his logic.arrow_forward

- Tully is a graduating high school senior deciding between three alternative combinations of education-work options. He could start working immediately and earn $30,000 working in a burrito truck in period one. His salary would increase to $60,000 in period 2 as he would become chef, and then fall in period 3 to $50,000 as he would become too physically tired to work too much in the kitchen. His first alternative is to spend $15,000 to attend Da-Lousy University for economics and earn an undergrad degree in period 1. Upon obtaining his degree he would earn $80,000 as an economist for periods 2 and 3. The final option is for Tully to complete a doctorate degree in economics after finishing his undergrad degree. There would be no direct costs as he would get scholarships, but he could not work in period 2 while he completed his PhD. After finishing his PhD he would earn $200,000 as an Econ Prof at Kings University in period 3. His discount rate is 15 percent per period.

- (2) Consider a Robinson Crusoe's economy, where he has 10 hours to spend on gathering coconuts (L), or a leisure (R). That is, L + R = 10. He can produce coconuts based on the production function given by C = 4√L, where C is the number of coconuts. He does not enjoy gathering coconuts, but does enjoy his leisure time and eating coconuts. His utility function is given by u(C, R) = CR. (a) Find the optimal allocation (C*, L*), in which Robinson Crusoe acts as a social planner. (b) Now consider a de-centralized economy. That is, think of this economy that consists of many individuals with the identical taste and technology. First, consider a firm's decision problem. The firm produces coconuts (C), employing workers (L). The firm hires L in a competitive market, given the wage rate (w). Without loss of generality, assume the price of coconuts to be Pc = 1. Given the market wage rate (w), how much labour would a firm hire in order to maximize its profits? Label your answer as L, and note…arrow_forwardYou have two options for how to spend the afternoon. You can either go see a movie with your roommate or work as a tutor for the Math Department. From experience, you know that going to see a movie gives you $20 worth of enjoyment, and with your student discount, a movie ticket only costs $12. If you spend the afternoon working as a math tutor, you will get paid $45. On a typical day, you wouldn't be willing to spend the afternoon working as a math tutor for less than $35. What is your opportunity cost of seeing a movie this afternoon?

Now Easton has asked you to evaluate the effectiveness of the spending increase. Their data show that before the spending increase, the average annual salary of recent high school graduates was $25,000 and that now that average salary has risen to $28,500. Fortunately for your analysis, a neighboring community (Allentown) did not change its annual spending on education. Ten years ago, recent Allentown high school graduates earned an average of $22,500, and now that average is $23,750. (a) Use a difference-in-differences estimator to determine whether Easton’s spending increase caused the wages of their high school graduates to increase.
