In our example:
The demanders of dollars are Japanese households and firms who want to buy American PRODUCTS and FINANCIAL ASSETS.
The suppliers of dollars are American households and firms who want to buy Japanese PRODUCTS and FINANCIAL ASSETS.
More Specifically, suppose X-box is $300, Playstation is 27,000Yen, and indirect exchange rate is 90Yen/$. Assume Microsoft wants dollars and Sony wants Yen. Prices don't change regardless of exchange rate.
Q: What is the cost of a playstation for an American consumer? What is the cost of an X-box for a Japanese Consumer?
Q: Suppose Yen appreciates so that the exchange rate is now 80Yen/$. What is the cost of a playstation for an American consumer? What is the cost of an X-box for a Japanese Consumer?
Result: When Yen appreciates (dollar depreciates), American goods become less expensive for Japanese consumers. Japanese goods become more expensive for American consumers.
The quantity demand of dollars by the Japanese rises.
The quantity supply of dollars by the Americans falls.
Q: Suppose demand for IPads increase in Japan.
