13. Purchasing Power Parity and Real Exchange Rates
Purchasing power parity (PPP) is a method of calculating exchange rates that values currencies at rates such that each currency will buy an equal basket of goods
According to PPP, if a basket of goods costs $7 in the U.S. and ¥1000 in Japan, the exchange rate should be
$1 = 1000/7 = ¥143
Purchasing power parity exchange rates may or may not be appropriate long-run exchange rates

14. Real Exchange Rates
A real exchange rate is an exchange rate adjusted for differential inflation or differential changes in the price level.
A nominal exchange rate is the actual exchange rate used when currencies are exchanged
%Δ real exchange rate =
%Δ nominal exchange rate + (domestic – foreign inflation)

15. Alternative Exchange Rate Systems
Three exchange rate regimes are:
Fixed exchange rate where the government chooses an exchange rate and offers to buy and sell currencies at that rate
Flexible exchange rate where the determination of exchange rates is left totally up to the market
Partially flexible exchange rate where the government sometimes buys or sells currencies to influence the exchange rate, while at other times letting private market forces operate
