Final answer:
For the purchasing power parity of the Audi A8, with prices at $61,000 in the U.S. and C$82,000 in Canada, the U.S. dollar to Canadian dollar exchange rate should be adjusted to $1.00 = C$1.34.
Step-by-step explanation:
To determine the exchange rate needed for purchasing power parity (PPP) of the Audi A8 based on its prices in the United States and Canada, we use the current prices in both countries. The car sells for $61,000 in the U.S. and C$82,000 in Canada. With an initial exchange rate of $1.00 to C$1.00, we calculate the new rate by dividing the Canadian price by the U.S. price.
The calculation is as follows: C$82,000 ÷ $61,000 ≈ 1.34426. This means that for purchasing power parity, $1.00 U.S. dollar should be able to buy approximately C$1.34. Therefore, the exchange rate should be $1.00 = C$1.34 for the prices of the Audi A8 in both countries to be equivalent.
In conclusion, for the PPP of the Audi A8, $1.00 U.S. dollar must be able to buy C$1.34. This calculation assumes no transaction costs, taxes, or other market frictions that can affect actual arbitrage activities.
