Smokey's Garage, Inc., provides routine auto diagnostics for customers in the Atlanta, Georgia, metropolitan area. Tests are supervised by skilled mechanics using equipment produced by two leading competitors in the auto test equipment industry. Staff at the company estimate that 4 tests per hour could be performed if they added another Sunny Tune System (STS) machine and 6 tests per hour could be performed on a new machine, the Car Care Tower (CCT). The STS can be leased at a cost of $5,000 per month, and the CCT can be leased at a rate of $9,000 per month. Labor to operate either of the machines would cost $3,000 per month. All other costs are fixed. On average, each machine is operated 25 eight-hour days per month. Smokey’s receives $15 for each test performed.
A. Compute and interpret the net marginal revenue products for the two types of equipment?
B. Should the company lease more STS machines? What about more CCT machines? Explain your answer.

Using OLS estimation methodology, the study of Morelli and Smith (2015) uses a cross sectional data of 2490 cars for the year 2013 to estimate the factors affecting the price of automobiles in the state of California. The estimation results of regressing the price variable on a set of explanatory variables are shown in Model (1), where the numbers in parentheses are the robust standard errors of the coefficients.
????? = 5647.02 + 5.77 ????ℎ? + 23.64 ??? + 3573.09 ??????? (1)
(1042.20) (1.50) (13.74) (1230)
???_?^2= 0.65, ? = 2490
Where price is in U.S. dollars, weight is in pounds, mpg is the number of miles per gallon, and foreign is a dummy variable that takes 1 if the ith car is foreign and 0 if domestic.
????? = 5524.02 + 6.54 ????ℎ? + 22.73 ??? + 3568.11 ??????? − 93.48 ?????ℎ (2)
(1033.10) (4.85) (13.68) (1232) (32.87)
???_?^2 = 0.92, ? = 2490
If the F-statistic of the coefficients of the four included variables in Model (2) is equal to 54.32, does the inclusion of the variable length in Model (2) creates an econometric problem? Explain in details.
????? = 5631.24 + 4.95 ????ℎ? + 25.99 ??? + 3650.22 ??????? + 88.31 ????? (3)
(1144.67) (1.62) (13.54) (1285.29) (44.38)
???_?^2 = 0.75, ? = 2490
Suppose that the correlations between the variable trunk and the variables price, weight, mpg, and foreign are equal to 0.25, 0.49, -0.38, and -0.36, respectively. Based on these correlations, refer to Model (1) and discuss the direction of the bias of each coefficient of the three included variables. What is your opinion about including the variable trunk as an additional regressor in Model (3)? Does the inclusion of the variable trunk violate any of the OLS assumptions? Explain in details.

Suppose that there are four people who enjoy a public good. One person has a willingness to pay for the public good of 20 - Q, while the other three each have a willingness to pay of 10 -Q/3.
a) Derive the aggregate willingness to pay?
b) Suppose that the marginal cost of providing the public good is 10. What is the efficient level of the public good, and how much will be supplied if there is no policy in place?
c) What is the deadweight-loss loss relative to the efficient solution - if there is no policy in place?

1. A million dollar lottery winner decides to quit working. How can you explain this behavior using economics?
2. How does outsourcing affect wages and unemployment in the short run and the long run?
3. If workers became more productive (produced more output in the same amount of time), what would happen to the demand for labor, the wages of labor, and the number of workers employed?
4. Why is it difficult to determine the amount of wage discrimination in the workplace?
5. Which anti-poverty program (welfare, in-kind transfer, or EITC) creates the strongest incentive for recipients to work? Why?

What did Smith mean by the Division of Labor and why did he see it as crucial to explaining the Wealth of Nations? What is the cause of the Division of Labor, for Smith? How does the division of labor increase productivity, in his view? What is the effect on workers? Explain how Smith's work on the division of labor challenges the standard neo-classical account of the economy built on the assumption of constant returns, and how it supports a different argument for free trade than we get from Ricardo's theory of comparative advantage

a. Josiah Bartlett collects 2 goods, carving knives (C) and antique books (B). His utility function is U(C, B) = 2C + B (they are perfect substitutes). Find Josiah’s demand curve for carving knives if he has $100 to spend and the price of antique books is $10.
b. Josiah's assistant Charlie collects the same two goods but has a different utility function: U(C, B) = min{2C, B} (they are perfect complements). Find Charlie’s demand curve for carving knives if he has $100 to spend and the price of antique books is $10.

Consider the following two investment alternatives, in which Alternative II is more economically attractive than Alternative I:
Alternative I Alternative II
Initial Investment $10,000 $40,000
Useful life 5 years 10 years
Terminal market value $1,000 $5,000
Annual expenses $20,000 $7,000
EUAC (12%), approx. $22,617 $13,800
Determine the percent change in the annual expenses for Alternative I that would make the two investments equally attractive. (Enter your answer as a positive or negative number without the percent % sign.)
