A soda would cost 2 dollars in the USA, and the same soda costs 3.5 yen in Japan. If the USA/JAP exchange rate is 1 USD = 2 JPY, then PPP (does/does not)_____________ exist. If it did, the soda would cost yen______________ in Japan.
Ans. If Purchasing Power Parity is satisfied then,
Exchange rate (Yen/Dollar) = Price of soda in Japan/ Price of soda in USA
=> Thus, a $2 soda must cost,
Price if soda in Japan = 2*2 = 4 Yen
So, if purchasing power parity holds then, the $2 soda would
cost 4 Yen in Japan.
Thus, purchasing power parity does not hold as price of $2 soda is
3.5 Yen in Japan not 4 yen.
