Review Questions

• Explain how the exchange rate affects a country's international trade and competitiveness.
  • The exchange rate plays a crucial role in a country's international trade and competitiveness. A stronger currency makes imports cheaper and exports more expensive, which can lead to a trade deficit as domestic consumers purchase more foreign goods. Conversely, a weaker currency makes imports more expensive and exports more affordable, potentially boosting a country's trade surplus and the competitiveness of its exports in the global market. The exchange rate, therefore, is a key factor in determining a country's trade balance and its ability to compete effectively in international trade.
• Describe the differences between a floating and a fixed exchange rate system, and discuss the advantages and disadvantages of each.
  • In a floating exchange rate system, the value of a currency is determined by the foreign exchange market based on the supply and demand for that currency. This system allows the exchange rate to fluctuate freely, which can help a country adjust to economic shocks and maintain its trade balance. However, it also introduces more volatility and uncertainty in the foreign exchange market. In contrast, a fixed exchange rate system pegs the value of a currency to another currency or a basket of currencies, with the government or central bank actively intervening to maintain the exchange rate within a predetermined range. This system provides more stability and predictability, but it can also limit a country's ability to respond to economic changes and may require the government to hold large foreign exchange reserves to defend the fixed rate.
• Analyze how changes in exchange rates can impact a country's inflation and the purchasing power of its citizens.
  • Changes in exchange rates can have a significant impact on a country's inflation and the purchasing power of its citizens. A depreciation of the domestic currency makes imported goods more expensive, leading to higher inflation as the prices of imported goods and services rise. This can erode the purchasing power of citizens, as their currency buys fewer foreign goods and services. Conversely, an appreciation of the domestic currency can reduce the cost of imports, potentially lowering inflation and increasing the purchasing power of citizens. However, this can also make a country's exports less competitive, which can negatively impact its trade balance and economic growth. Policymakers must carefully balance the trade-offs between exchange rate movements, inflation, and the overall economic well-being of the country and its citizens.
