Parity conditions
 For parity to hold
 efficient market conditions needed

existence of frictions in the market

in the exchange markets

Economic Growth
 Growth increases the demand for money

demand for money curve shifts up
 Assume CB keeps money supply constant
 no change in the vertical supply curve
 the value of money increases
 prices and value of money inversely related
 domestically - deflation
 internationally - exchange rate appreciation

Money Supply
 Central Bank increases supply of money
 supply curve shifts out
 Assuming no change in demand for money
 the demand for money curve remains stationary
 the value of money decreases
 prices and value of money inversely related
 domestically - inflation
 internationally - exchange rate depreciation

Shift in Term Structure of
Interest Rates
 Central bank changes the bank rate
 only rate directly controlled by CB
 least risky rate in the economy
 no default risk

 other rates will ratchet up relative to risk
 default - ability to pay
 interest rate risk - relative to term to maturity
