The US dollar appreciates significantly against the euro. Which of the following effects would this most directly cause?
AUS exports become cheaper for European buyers, boosting US export sales
BUS exports become more expensive for European buyers, hurting US export sales
CUS imports become more expensive for American consumers
DEuropean tourists find the US more affordable to visit
When the dollar appreciates, each euro buys fewer dollars — meaning foreigners must spend more of their own currency to buy the same US goods. This makes US exports more expensive to foreign buyers and reduces demand for them. Option C is wrong: a stronger dollar makes imports *cheaper* for Americans, not more expensive. Option D is wrong: a stronger dollar makes the US *more* expensive for foreign tourists, not less.
Question 2 Multiple Choice
Country A has 8% annual inflation while Country B has 2%. The nominal exchange rate between them is unchanged over the year. What has happened to Country A's real exchange rate and trade competitiveness?
ACountry A has become more competitive because its currency remained stable
BCountry A has become less competitive because its goods are now relatively more expensive in real terms
CCompetitiveness is unchanged because the nominal exchange rate did not move
DCountry A has become more competitive because inflation signals faster economic growth
The real exchange rate adjusts the nominal rate for relative price levels. If Country A's prices rose 8% while Country B's rose only 2%, Country A's goods are now about 6% more expensive in real terms — even though the nominal rate is unchanged. This is why economists focus on real exchange rates when analyzing trade: a nominal rate that holds steady while domestic inflation exceeds foreign inflation represents a real appreciation and a loss of competitiveness.
Question 3 True / False
A currency appreciation that merely reflects higher domestic inflation relative to a trading partner does not represent a genuine loss of international competitiveness.
TTrue
FFalse
Answer: True
The real exchange rate = (Nominal rate × Domestic price level) / Foreign price level. If the nominal rate depreciates (currency weakens) by exactly as much as domestic inflation exceeds foreign inflation, the real exchange rate is unchanged — goods are no more or less expensive in real terms. Conversely, a nominal appreciation that only tracks inflation differentials leaves the real rate and competitiveness unchanged. This is why the real exchange rate, not the nominal rate, is the appropriate measure of trade competitiveness.
Question 4 True / False
A stronger national currency is generally beneficial for the overall economy because it increases purchasing power and therefore improves economic welfare.
TTrue
FFalse
Answer: False
This is the most common misconception about exchange rates. A stronger currency creates winners and losers: it benefits importers (cheaper foreign goods), consumers of imported products, and those traveling abroad, but it hurts exporters (their goods become more expensive to foreign buyers) and import-competing domestic manufacturers. For an export-dependent economy like Germany or South Korea, a strong currency can seriously damage economic output. There is no unambiguously 'better' exchange rate level.
Question 5 Short Answer
Why do economists focus on the real exchange rate rather than the nominal exchange rate when analyzing a country's international trade competitiveness?
Think about your answer, then reveal below.
Model answer: The nominal exchange rate is the quoted market price of one currency in terms of another, but it does not account for differences in price levels between countries. What matters for trade competitiveness is whether a country's goods are actually cheap or expensive for foreign buyers after adjusting for inflation. The real exchange rate makes this adjustment: Real rate = (Nominal rate × Domestic price level) / Foreign price level. A country with 10% higher inflation than its trading partner becomes less competitive even if the nominal rate is unchanged, because its goods now cost more in real terms.
The key insight is that trade flows respond to relative prices in real terms, not the nominal currency price. PPP theory formalizes this: in the long run, exchange rates should equalize the purchasing power of currencies across countries. This also explains why economists use PPP-adjusted GDP comparisons rather than nominal GDP when comparing living standards across countries with different price levels.
