2. No, there is not cross-rate equality, since ($.0075/yen)/ (£.005/yen) = $1.50/£, not
$2.00/£. Consequently, arbitragers would use dollars to acquire yen, use yen to acquire pounds,
3. This statement is true. Unless one knows what happened to relative prices in the two
4. The real exchange rate provides an estimate of the purchasing power of a currency
relative to some previous period by removing the effect of price changes in each country by

Given the 2014 exchange rate of 14.72 peso/$, PPPrel would suggest that the peso is undervalued
6. The condition for equilibrium in this instance is that iNY ≈ iLondon + xa – RP [or (iNY –
iLondon) ≈ xa – RP]. In this example, the rate of return in New York is less than the expected rate
of return in London after accounting for expected depreciation of the pound and the required
payment for risk associated with the U.K. investment, i.e., 0.02 < 0.06 + (-0.01) – 0.02, [or (0.02
– 0.06) < (-0.01 – 0.02)]. As a result, investment funds should flow from the United States to the
United Kingdom. This raises the spot rate on pounds and, other things equal, reduces xa since xa
