(a) What is the difference between Law of One Price (LOP) and Purchasing Power Parity (PPP)?
(b) Consider a world that only comprises 3 goods (Good 1, Good 2, Good 3) and 2 countries (France and Japan). Assume that consumption weights of these goods for both countries be (0.50, 0.25, 0.25).
The price of the goods at time t are listed below:
France (EUR) Japan (JPY)
Good 1 40 20
Good 2 80 55
Good 3 60 150
Note: EUR stands for Euros and JPY stands for Japanese yen
(i) For each good, what exchange rate, S(EUR/JPY), is consistent with the law of one price?
