Please help me with the following multiple choice questions. Thank you in advanced!

a) Assume that the prices of cars manufactured in Canada increase due to an increase in quality. Which of the following will happen if the same number of cars is sold?

• real GDP should increase but nominal GDP should stay the same
• nominal GDP should increase
• the GDP-deflator should decrease
• real GDP and the GDP-deflator should decrease
• both nominal GDP and real GDP should decrease

b) Assume government purchases = $1,500, the budget deficit = $120, consumption = $4,800, saving = $1,220, the trade deficit = $90, and transfer payments = $0. Which of the following is true?

• investment is $1,220
• national income is $7,400
• disposable income is $3,580
• tax revenue is $1,620
• national income is $7,800

c) The consumer price index (CPI) measures

• the average cost of raw materials purchased by producers
• the average price of energy prices
• the cost of buying a fixed basket of goods and services of a representative consumer
• price of final as well as semi-finished goods
• the average cost of all final goods excluding energy

d) If Canadian budget deficit increased substantially while saving and investment remained roughly the same, then

• Canada imported more than it exported
• Canada exported more than it imported
• Canada must have experienced a major recession
• Government transfer must have increased substantially
• Tax revenue must have increased substantially

e) The GDP-deflator and the consumer price index (CPI) differ since

• the CPI measures a fixed market basket but the GDP-deflator doesn't
• the GDP-deflator includes imported goods but the CPI doesn't
• the CPI includes more goods than the GDP-deflator
• the GDP-deflator does not include services but the CPI does
• the GDP-deflator measures increases in inflation earlier than the CPI

f) If nominal GDP was $9,200 billion in Year 1 and $9,420 billion in Year 2 and prices increased from Year 1 to Year 2, then

• real GDP must have been larger in Year 1 than in Year 2
• real GDP must have been larger in Year 2 than in Year 1
• the GDP deflator must have been 122
• the GDP deflator must have been 102
• we cannot determine the value of the GDP deflator or real GDP in Year 2

g) If nominal GDP is $8,820 billion and the GDP-deflator is 105, then real GDP is

• $9,261 billion
• $8,925 billion
• $8,715 billion
• $8,400 billion
• $8,000 billion

h) If we counted the value of autoworkers' salaries, wheels, tires, steel, body parts, and final car sales in calculating GDP, then we would be

• understating GDP by overlooking car dealers' profits
• ignoring the contribution of capital to output
• overstating GDP through double counting
• using the value-added technique for calculating GDP
• calculating GDP correctly only if we excluded any imported cars

i) For a simple economy with no depreciation, no government, and no foreign sector, which of the following identities would be correct?

• Y C
• C - I S
• Y - C S
• Y - C S + I
• Y C + S - I

j) Which of the following identities is FALSE?

• Y C + I + G + NX
• YD Y - TA + TR
• BS TA - TR - G
• I - S (G - TA + TR) + NX
• S + TA - TR I + G + NX

Thank you so much!
