PPP, Price Levels And Exchange Rates In The LR Flashcards
What is the real exchange rate?
- rate of exchange for goods and services across countries
What is the formula for the real exchange rate
q=E X P(F) / P(H)
Hence,
E=P(H)/P(F) X q
What does a real depreciation in the home currency mean?
- q increases
- implies value of domestic goods relative to value of foreign goods falls
What does a real appreciation in the home currency mean?
- q decreases
- implies value of domestic goods relative to foreign goods rises
Describe why relative demand is upward sloping
- as q increases foreign goods become more expensive
- demand for domestic goods increases relative to foreign goods
- domestic output increased
When is real exchange rate at its equilibrium level?
When relative demand=relative supply
Describe the effect of an increase in RD of domestic goods on the real exchange rate
- increase in RD of domestic goods shifts RD curve right
- value of formative goods relative to foreign goods rises
- excess demand
- real appreciation of domestic goods
- q falls
- real appreciation decreases exports
- increased imports
- NX falls
- reducing relative quantity demanded of domestic goods
Describe the increase in relative supply of domestic goods
- RS curve shifts right
- domestic output has risen relative to foreign output
- causes price of domestic goods relative to cost of foreign goods to fall
- excess supply
- real depreciation of value of domestic goods
- q rosed
- imports fall
- exports rise
- NX rises
- increase im relative demand of US goods until equilibrium reached
Describe an increase of relative demand of domestic goods on the nominal exchange rate
- increase in RD
- real exchange rate falls
- nominal exchange rate falls
- home currency appreciates
- nominal and real appreciation of domestic currency
- no effect on long-run price levels
Describe the effect of an increase in relative supply of domestic goods on the nominal exchange rate
- increase in RS
- q rises
- increase in real output domestically increases real money demand
- domestic prices fall
- effect on nominal exchange rate is ambiguous
What is the real interest parity?
The real interest rate differential = growth in the real exchange rate
