1.Part 1: 20 questions worth 3 points each for a total of 60 points.
FOR FILL-IN-THE-BLANK questions: If your answer is in decimal form, round to 2 decimal places. For example, if your answer is .412, enter it into the fill-in-the-blank as .41, or if your answer is 1.415, enter it into the fill-in-the-blank as 1.42. If there are no decimals in your answer, you will simply enter the number; so if your answer is 2, enter 2 with no decimals. Do not enter any extra spaces, do not enter $ or % symbols.
Suppose the consumption function is: C = a1 Yd + a2 WRE/S + a3CC Where all the a's (the sensitivity parameters) are greater than zero. Initial conditions: Let a1 = 0.60, a2 = 0.04, a3 = .5, WRE/S = 18,000: CC = 90 Solve for C in terms of Yd. Select the correct equation below.
A) C = 720 + .60 Yd
B) C = 765 + .60 Yd
C) C = 765 + .64 Yd
D) C = 90 + .60 Yd
E) None of the above are correct
2.Use the equation you found in #1 and let Yd = 2000. C is equal to .
3.Suppose that the stock market rallies so that WRE/S increases to 22,000. Additionally, consumer confidence (CC) rises to 100. Re-solve for C in terms of Yd. Select the correct equation below.
A) C = 720 + .65 Yd
B) C = 880 + .60 Yd
C) C = 765 + .64 Yd
D) C = 930 + .60 Yd
E) None of the above are correct
4.Now suppose disposable income (Yd) falls due to a tax increase (Uncle Sam is trying to balance the budget) to 1800. Solve for the level of consumption using the equation you found in #3. Consumption (C) is equal to .
5.Now we will calculate the level of consumption that would have occurred if Uncle Sam did not raise taxes. In other words, use the equation you found in question 3, but keep Yd at its original value of 2000. Consumption (C) is equal to .
6.Look at the consumption values you calculated in #2 and #4. The percent change in consumption between those values is %
NOTE: There is no graphing component to be collected for this homework. However, you should be comfortable graphing the equations you found in #1 and #3. You should also be able to plot the points you found in #2, #4 and #5.
7.Use the table below for questions 7 & 8. Let's consider some data on consumption and disposable income from the Federal Reserve Database (measured in billions of dollars)
Real Personal Consumption Expenditures Real Disposable Personal Income
January 1, 1990 5658.8 6376.6
April 1, 2013 10690.9 11591.4
The percent change in consumption between 1/1/90 and 4/1/13 is %.
8.The percent change in real disposable between 1/1/90 and 4/1/13 is %.
9.Given equation Y=330+.8Y, what does Y equal?
A) 183.33
B) 412.5
C) 1650
D) 264
E) None of the above are correct

C) 60 Computer Chips
D) 50 computer Chips
14.Using comparative advantage, which country should import bed linens?
A) United States
B) South Korea
C) Both countries have a comparative advantage in computer chips, so both should import bed linens
D) Both countries have a comparative advantage in bed linens, so both should import bed linens
