where S is the nominal exchange rate, P is the U.S. price level and P* is the price level in the country of
interest, say Ghana. When the real exchange rate is appreciating, it means the U.S. price of the bundle

of goods in the basket is increasing relative to the Ghanaian price. Now, when the real exchange rates
appreciates, then the real value of the dollar has depreciated, suggesting a decline in its purchasing
power, relatively speaking.
To get to know how Q affects the poverty level, it is necessary to try to understand the factors that
influence changes in Q. The real exchange rate between the currencies of the two countries may
change when there is a change in the relative demand for U.S. goods as a result of preference shift,
leading to total expenditure on U.S. goods increasing. The shift may arise from two principal sources.
An increase in global private and public demand for U.S. goods is one source of such shifts. This shift is
exacerbated when the relative increase in demand for U.S. goods is much higher than the increase in
demand for Ghana goods. In an increasingly interconnected world, imports tend to account increasing
share of development countries’ consumption. Another source of the shift is an increase in U.S.
Government expenditure on U.S. goods, an event that increases during recessionary periods in attempts
to boost demand as an economic stimulant. When these events shift the demand for U.S. goods,
equilibrium can only be restored if the relative price of U.S. goods vis‐à‐vis Ghana goods rose. From
Equation (1), this implies a decline in Q, i.e., the purchasing power of the U.S. dollar has increased
relative to the Ghana cedi. The corollary is true: that the purchasing power of the Ghana cedi has
declined and its purchasing power has fallen.

Another source of change in the real exchange rate is a change in relative output supply in the U.S.
significantly exceeding that of Ghana. Output supply changes are a function of resource productivity‐
enhancing technologies, such as those for labor and capital. Tractors and other farm production
equipment are some of the visible productivity‐enhancing technologies that allow U.S. agriculture, for
example, to dwarf that of Ghana. One outcome of increasing productivity is increasing incomes and the
country with the highest relative productivity increase will also have the highest relative income
increase. Because the higher incomes often lead to increased consumption of imports, relative prices in
the U.S. need to fall to restore equilibrium. This fall in relative prices lead to an increase in Q and a fall
in the U.S. dollar in real terms. Conversely, Ghana’s relative productivity disadvantage suggests the
need for appreciation of the Ghana cedi in order to restore equilibrium, leading to an increase in
Ghana’s prices relative to those in the U.S., i.e., the Ghana cedi rises in real terms. The foregoing works
well if the goods and services in the basket of goods being compared between the two countries are all
traded. However, a fair proportion of goods in the basket of developing countries tend to be non‐
traded.
