Sales tax is part of the value or price of the good and is thus counted. Add $2.13 to Consumption. c. The car is not resold, so the $10,000 of accesories are finished goods (not resold). Add $10,000 to consumption. d. The good is produced in the US and foreign workers working in the US are counted. Add $5,000 to wages and $6,000 to profits for a total of $11,000. e. China adds $200 of value added which is not counted. Lucky adds 2 · $125 $200 = $50 of value added. Nordstrom adds 2 · $125 2 · $125 = $50 of value added. Total value added is thus $100. Note that I have counted the inventory as a revenue to Nordstrom. This is consistent with the idea that Nordstrom “sold” the good to itelf, and has an inventory asset worth $150. Question 2 (30 points). a. For nominal GDP, we have: NGDP 2009 = 2 * $50 + 30 * $7 + 20 * $40 + 50 * $10 + 60 * $1 = $1 , 670 (1) Similarly, the nominal GDP for 2010 is $1,970 and for 2011 is $2030. b. The GDP deflator is always 100 for the base year, in this case 2009. For 2010, we have: GDP deflator 2010 = NGDP 2 * $50 + 40 * $7 + 22 * $40 + 50 * $10 + 40 * $1 × 100 = $1 , 970 $1800 100 = 109 . 4 (2) For 2011, I get 114.7. c. Real GDP is equal to nominal GDP in the base year, hence real GDP for 2009 is $1,670. For 2010, we have: RGDP 2010 = $1 , 970 109 . 4 100 = $1 , 800 (3) 1 One could arrive at the same answer by using current goods and base prices. For 2011, the real GDP is $1,770. d. The CPI for the base year (2009) is 100. For 2010, we have: CPI 2010 = 2 * $50 + 30 * $7 + 20 * $45 + 50 * $11 + 60 * $1 . 25 NGDP 2009 × 100 = $1 , 835 $1 , 670 100 = 109 . 9 (4)...
