int'l parity conditions (lecture #11) Flashcards
what happens with a fixed exchange rate in terms of government intervention?
if demand for currency is going, gov. will intervene to increase supply
-this causes foreign exchange reserves to increase because the ‘home’ country is selling their currency, and getting new currency
def. law of one price
states that all else being equal (no transaction costs or restrictions) a product’s price should be the same in all markets
regarding PPP, what would happen if the law of one price were true for all goods
the PPP exchange rate could be found from any set of prices
what is the absolute theory of purchasing power parity
absolute PPP states that the spot exchange rate is determined by the relative prices of similar basket of goods
describe the “Big Mac Index”
- prime example of the law of one price
- assuming that the Big Mac is identical in all countries
- serves as a comparison point as to whether or not currencies are trading at market prices
what do empirical tests of both relative and absolute PPP show
- PPP tends to not be accurate in predicting future exchange rates
- PPP holds up well over the very long term but is poor for short term estimates
- the theory holds better for countries with relatively high rates of inflation and underdeveloped capital markets
