21) Assume the following open economy for Questions 1a, 1b, 1c and 1d below: — 48 points C = 300 + 0. 80(Y – 125)
I = 150
G = 250
X = 115
M = 125+. 05Y
21a). Determine (solve for) the equilibrium level of income or GDP (Y). The planned expenditure line is c+i+g+mx. I believe from the notation used in the problem that x is exports and m is imports so that mx= 115-(125+. 5y) = -10-. 5y. Thus, expenditures are 300 +. 8(y-125) + 150 + 250 – 10 – . 5y. This simplifies to 590 + . 3y. Thus, this intersects the 45-degree line at 842. 86 (the y where 590 + . 3y = y).
21b). Determine the impact on income of a 50 increase in government spending from 250 to 300. Adding 50 to g increases the expenditure line to 640 +. 3y. Thus, at y= 914. 29, y = 640 + . 3y.
21c). Using the original data, compute the impact of a 50 decrease in taxes from 125 to 75. The new level of consumption is c = 300 + . 8(y – 75) = 300 + . 8y + . 8(75) = 360 + . 8y. Plugging this into the new expenditure line you get 550 + . 3y. The y where y = 550 + . 3y is y= 785. 71.
21d). If the government seeks to raise income to 3, 000, how much should it raise government spending? To solve the problem, we need to backtrack the work. We want y to equal 3000. Thus, we want the new intercept term to the expenditure line, x, to be such that 3000 = x + . 3(3000), which simplifies to 2100 = x. The original problem (with g= 250) had the intercept equal 590. Thus, g needs to increase by 1510 to g= 1760 for y to equal 300
22. In calculating GDP, we normally exclude intermediate goods produced and used during the period under question. Explain why it is the case that the value of intermediate goods produced and sold during the year is not included directly as part of GDP, but the value of intermediate goods produced and not sold is included directly as part of GDP. – 12 points Intermediate goods produced and sold during the year are not included separately as part of GDP because the value of those goods will be included in the value of the final goods produced from them. If the intermediate good is produced but not sold during the year, its value is included as inventory investment for the year in which it was produced. If inventory investment was not included as part of GDP, true production would be underestimated for the year the intermediate good went into inventory, and overestimated for the year the intermediate good is used or sold. 23. Use the data on U. S. real GDP below to compute real GDP per person for each year. Then use these numbers to compute the percentage increase in real GDP per person from 1987 to 2005. There are 3 questions here gang. – 36 points

24). The table below uses data for the year 2003 provided by the Bureau of Labor Statistics and adjusted to be comparable to U. S. data. All values are in thousands. Fill in the blank entries in the table. — 48 points Country| AdultPopulation| LaborForce| Employed| Unemployed| UnemploymentRate| Labor-ForceParticipationRate| Japan| 109, 474| 66010| 62, 510| 3, 500| 5. 3%| 60. 29%|
France| 46803| 26, 870| 24293| 2, 577| 9. 5%| 57. 41|
Germany| 70, 159| 39, 591| 35754| 3836| 9. 69| 56. 4%| 25). . Teenage unemployment is higher than unemployment of people ages 20 and over. Explain why economists would attribute at least part of this difference to minimum-wage laws. – 12 points. Since teenagers possess less skills, education, training, and experience than most people who are much older there is less of a demand for their services especially at higher wages. If the government sets a minimum wage it is a way of setting up a sort of “ price floor” for labor charges. It can increase the supply and reduce the demand for teenage labor and therefore not allowing the market to clear at the equilibrium price and leading to an excess supply of labor, and finally unemployment.
Question 26) has 3 parts. Compute how much each of the following items is worth in terms of 2011 dollars using 177 as the price index for 2011. – 34 points 26a). In 1936, the CPI was 17. 7 and the price of a movie ticket was $0. 25. CPI1/CPI2 = P1/P2
17. 7/177 = $0. 25/P2
P2 = $2. 5
price of a movie ticket in 2011 = $2. 5
26b). In 1942, the CPI was 13. 1 and a cook earned $15. 00 a week. b. 13. 1/177 = $15. 00/P2
P2 = $15. 00*177/13. 1 =$202. 67
cook earned $202. 67 a week in 2011
26c). In 1953, the CPI was 17. 4 and a gallon of gas cost $0. 19.
c. 17. 4/177 = $0. 19/P2
P2 = $0. 19*177/17. 4
P2 = 1. 93
gallon of gas cost $1. 93 in 2011
