Final answer:
A change in exchange rates making the euro cheaper for Americans would be expected to decrease U.S. exports to Germany, as U.S. goods become more expensive for Germans. Factors such as declining U.S. interest rates or an improved EU economy also have significant effects on exchange rates and trade balance.
Step-by-step explanation:
If exchange rates change such that the euro becomes cheaper for Americans to buy, we would expect U.S. exports to Germany to decrease. This is because the dollar has become relatively stronger compared to the euro, making U.S. goods more expensive for Germans to purchase. Consequently, demand for U.S. exports in Germany would likely diminish. If all else remains the same, such a scenario could potentially lead to a trade imbalance where the U.S. starts experiencing a trade surplus while Germany might run into a trade deficit.
Reflecting upon the scenarios provided where U.S. interest rates decline or the EU's economy picks up speed after sluggish growth, these factors influence the exchange rate and trade balance. If U.S. interest rates decline, the demand for dollars might decrease, supply might increase, and the dollar might weaken against the euro. Conversely, if the EU's economy improves significantly, this could potentially lead to a higher demand for European goods, potentially worsening the U.S. trade balance with the EU, impacting U.S. GDP and employment negatively.
