Chapter 8 (Final Exam) Flashcards
What does the Purchasing Power Parity (PPP) theory explain?
It explains the relationship between inflation rates and exchange rates, suggesting that exchange rates adjust to equalize the price of goods across countries.
Note:
% change in exchange rate should be approx equal to the difference in inflation rate between 2 countries
What are the two forms of PPP?
Absolute PPP: Prices of identical products in different countries should be equal when expressed in a common currency.
Relative PPP: Exchange rates adjust to reflect differences in inflation rates between countries.
(Exchange rate in prices should be similar)
What happens if a country’s inflation rate is higher than another’s, according to PPP?
The currency of the country with higher inflation will depreciate relative to the other country’s currency.

ih<if
Then, ef (Derivation of PPP) should be -, foreign currency deppreciates
How can PPP be used to estimate exchange rate changes?
By comparing the inflation rate differences between two countries

What is the International Fisher Effect (IFE)?
It states that currencies with higher nominal interest rates will depreciate because higher rates reflect higher expected inflation.
How does IFE affect investors?
Investors earn similar returns on domestic and foreign investments after accounting for currency depreciation.
How are PPP and IFE connected?
Both involve inflation: PPP focuses on how inflation differences affect exchange rates, while IFE links interest rates to inflation and exchange rates.
What are the limitations of PPP?
-Exchange rates are affected by more than inflation (e.g., income levels, interest rates, government controls & expectations).
-Not all goods have substitutes, so trade may not equalize prices.
What are the limitations of IFE?
-The actual inflation rate may differ from expected inflation.
-High interest rates in a country can attract capital, strengthening its currency instead of causing depreciation.
What happens if PPP or IFE does not hold in reality?
Investment in foreign securities may yield higher or lower returns than domestic investments, depending on exchange rate movements.
