  1. Which of the following is correct?
    1. The economy has a healthy debt burden as long as the nominal income growth rate exceeds the real debt interest rate.
    2. If the debt/GDP ratio is 200% and debt interest rate is 10%, the debt interest payment will represent 20% of GDP.

  8. When planned domestic leakages exceed planned domestic injections in an open economy
    1. the domestic circular flow will expand.
    2. capital outflow can make up for the difference.
    3. the quantity produced will fall short of the quantity people want to buy domestically.
    4. imports will make up for the difference between the quantity produced and quantity bought domestically.
  9. The spending multiplier model assumes that
    1. the multiplier effect will go on forever once a stream of new spending is injected into the economy.

    1. the output pie shrinks.
    2. consumption is reduced.
    3. what is saved is recycled back to investment.
    4. investment is reduced.
  13. A constant growth rate will
    1. lead to an ever shorter doubling time of the initial value.
    2. double the positive initial value every 10 years.
    3. result in a growth curve with an increasing slope on a semi-log graph paper.
    4. not be sustainable in a finite world.
  14. Gross saving is
    1. saving including capital depreciation allowances.
    2. equal to gross domestic investment.
    3. saving excluding capital depreciation allowances.
    4. saving including foreign capital inflow.
  15. When planned injections exceed planned leakages in a closed economy
    1. there will be a shortages of goods and services.
    2. the quantity produced falls short of the quantity people want to buy.
    3. there will be a surplus of goods and services.
    4. the circular flow will shrink in the next round.
    5. Both A and B.
  16. Net capital inflow into America was funded by
    1. recycled trade surplus earned by foreign countries.
    2. American household savings.
    3. capital depreciation allowances set aside by America's corporate sector
    4. trade deficits incurred by foreign countries.
  17. The government can do new non-debt servicing borrowing without increasing the debt/GDP ratio if
    1. the new borrowing does not exceed the excess of income growth rate over the debt interest rate.
    2. the debt interest rate is higher than the income growth rate.
    3. the income growth rate is equal to the debt interest rate.
    4. Both A and B.
  18. The simple "crowding out" model is
    1. based on the circular-flow model in a closed economy.
    2. not related to the circular-flow model.
    3. based on the circular-flow model in an open economy.
    4. Both B and C.
  19. In an economic recession, higher consumption is good because
    1. higher spending on ANY investment would simply increase the productive capacity which is already under-utilized.
    2. it leads to higher saving.
    3. it reverses the spending multiplier effect.
    4. higher rate of saving would further erode aggregate demand for goods and services.
