Explanation:
Purchasing Power Parity (PPP) is said to hold when two currencies are in equilibrium (at par), and it is an economic theory that compares different currencies through an approach known as 'basket of goods approach'.
A PPP is said to exist when the same unit of good is priced the same in two different countries, taking into consideration the exchange rate of both currencies. PPP rates are considered more accurate measures than market exchange rates, because market exchange rates are influenced by several factors such as government intervention, different interest rates, speculation trading and edging.
PPP are also quite difficult to determine because of differences in purchasing habits, unequal qualities of the goods in the countries and differences in each country's economy, but once PPP is determined, it remains relatively constant over a long run.
Mathematically PPP is calculated as;
where;
S = exchange rate of currency 1 to currency 2 =
P₁ = cost of good X in currency 1
P₂ = cost of good X in currency 2
currency 1 = Canadian dollars
Currency 2 = U.S dollars
S = currency 1 : currency 2 = 1 : 0.71 = 1.4085
P₁ = 105 Canadian dollars
P₂ = ???
∴
P₂ = = 74.55 U.S dollars.
