Show Answers:

  1. NIA for National Savings
    Y – C – G = National Savings
  2. Relationship between National Savings and budget deficits
    Increase in G means a decrease in National Savings
  3. Where does the government get resources for spending?
    Taxes, selling assets, borrowing
  4. Two tools the government can use to get out of recessions?
    Increased spending, decreased taxes
  5. What is the interest rate impact of the Fed tightening the money supply?
    Short-term interest rates will increase. Long term, prices fall.
  6. Tightening the money supply should have what impact on inflation?
    Lower inflation
  7. How to get out of hyperinflation?
    Reduce spending, peg the currency, currency board
  8. What’s the cost of holding money?
    Nominal interest
  9. What is the impact on the CA of an increase in the budget deficit?
    The CA will fall.
  10. CA =
    S – I or EX – IM
  11. Quantity Theory Equation:
    Change in Money Supply + Change in Velocity = Change in Price Level + Change in Output
  12. T/F: There would be no inflation if money grew at the rate of growth of the economy
    F: it depends on V. If V is constant then there is no inflation.
  13. In a fixed exchange system, what must happen if there’s an excess supply of FX?
    CB must clear the market, increasing the supply of domestic currency, lowering interest.
  14. If there is unexpected inflation the bondholders (gain/lose)
    Lose. Their future payments will be worth less.
  15. Causes of FX Crisis in fixed regimes?
    Loss of confidence, decreased demand for domestic goods/services, CA deficit
  16. Causes of low national savings in US over last 15 years?
    High G, Low T, low interest, increasing asset prices = higher portfolio value (perceived savings)
  17. Two ways to describe GDP:
    Total income of everyone in the economy. Total expenditure on the economy’s output.
  18. NIA
    Y = C + I + G + NX
  19. What parts of the NIA are impacted by fiscal policy?
    G and T
  20. Multipler Equation:
    Change in G x Multipler = Change in Y
  21. Why is the multipler hard to estimate?
    Rational Expectations, Crowding Out, Offsetting Monetary Polciy
  22. How do rational expectations impact estimations of the multipler?
    Budget deficit eventually has to be offset by taxes, so save for future taxes
  23. What is crowding out?
    Deficit spending increases interest rates, undercutting private I and C
  24. BOP Identity
    FA + CA = 0
  25. What does the FA measure?
    Cross-border trade in claims to capital
  26. What happens to the CA if I is NOT financed domestically?
    CA will fall because CA will decrease as I rises
  27. What happens to the CA if I is financed domestically?
    S and I increase in tandem, leaving CA unchanged.
  28. Types of currency (most liquid first):
    C, M1, M2, M3, L
  29. Monetary Policy:
    Changes in money supply or interest by the CB
  30. Problems with computing CPI:
    Substitution, List Prices, Quality Change, New Goods
  31. Seigniorage:
    Government purchases made by printing money
  32. Quantity Theory: If change in M > change in Y, what happens to P
    Increase in P aka INFLATION
  33. Fisher Equation
    Nominal Interest = Real Interest + Expected Inflation
  34. How to prevent seigniorage:
    Currency board, currency peg, create institutions to promote good monetary policy
  35. Tools of Monetary Policy:
    Discount Rate, Reserve Requirements, Open Market Operations
  36. Discount Rate:
    Rate at which the Fed lends to banks
  37. Federal Funds Rate:
    Market rate at which banks lend to one another overnight to meet reserve requirements.
  38. Quantitative Easing:
    Purchasing non-traditional assets on the secondary market to get bad debt off private balance sheets
  39. In Open Market Ops, how does the Fed pays for the bonds it buys?
    It credits the seller’s account with the Fed.
  40. Why don’t prices adjust faster?
    Menu costs, impact on business relationships, contract restrictions o
  41. Philips Curve:
    In the short run, a reduction in the money supply leads to unemployment.
  42. Why the Gold Standard is bad:
    No discretionary monetary policy, supply changes when gold is found, possible better uses for gold
  43. Why do countries peg exchange rates?
    Signal of stability, encourages trade, restricts CB’s power, gives government credibility
  44. How does a peg rely on reserves?
    The amount of money in circulation is a fixed proportion of the amount in reserves in the CB
  45. In which FX system is hyperinflation impossible?
  46. Disadvantages of pegging?
    No monetary policy, direct impact of foreign events, large reserves to stop speculation, FX crisis
  47. Does restricting capital flows work as monetary policy in with a pegged FX?
    NO! If gov tires to slow inflation by requiring bond purchase, locals look elsewhere, increasing inflation
  48. How to stop FX Crisis:
    Borrow more FX, raise interest rates, freeze assets/capital flows, devalue and abandon the peg
  49. What is the impact of abandoning the peg?
    The currency devalues, making FX too costly for locals, ending the FX crisis

  51. Carry Trade:
    Borrowing in a currency with a low interest rate to invest in a currency with high interest. Risky.
