International Investment and Real Returns

Suppose the nominal interest rate in Country A is 8% and its inflation rate is 3%. In Country B, the nominal interest rate is 6% and its inflation rate is 2%. Assuming financial markets are integrated and capital can move freely, what long-run adjustment is most likely to occur based on the principle that real returns tend to equalize across countries?

Implications of Equalized Real Returns

According to the theory that real returns tend to equalize across countries with integrated financial markets, if one country consistently experiences a higher inflation rate than another, its nominal interest rate must also be consistently higher in the long run.

Market Adjustment Mechanism for Real Returns

In a world with fully integrated financial markets where real returns are equalized across countries in the long run, match each economic scenario in a domestic country (relative to a foreign country) with its most likely long-run consequence.

Evaluating the Real-World Applicability of Interest Rate Equalization

Consider two countries, A and B, with fully integrated financial markets. The nominal interest rate in Country A is 5% and its inflation rate is 2%. The nominal interest rate in Country B is 7%. For the long-run condition of equal real returns between the two countries to hold, what must be the inflation rate in Country B?

Derivation of Real Return Equalization

Imagine a world with two large, financially integrated economies: Country A and Country B. The real rate of return on investment in Country A is currently 4%, while in Country B it is 2%. Given this difference, what is the most likely immediate reaction of global investors and the subsequent effect on interest rates?
