Review Questions

• Explain how exchange rates affect international trade and the flow of goods and services between countries.
  • Exchange rates play a crucial role in international trade by determining the relative prices of goods and services between countries. A strong domestic currency makes imports cheaper and exports more expensive, while a weak domestic currency has the opposite effect. This can influence the competitiveness of a country's exports and the affordability of its imports, affecting the flow of goods and services across borders. Fluctuations in exchange rates can lead to changes in the volume and direction of trade, as businesses and consumers adjust their purchasing decisions based on the relative prices of foreign and domestic products.
• Describe the differences between a floating exchange rate system and a fixed exchange rate system, and discuss the advantages and disadvantages of each.
  • In a floating exchange rate system, the exchange rate is determined by the foreign exchange market based on supply and demand, without direct government intervention. This system allows currencies to adjust to economic conditions and can help a country absorb external shocks. However, it can also lead to exchange rate volatility, which can create uncertainty for businesses and investors. In a fixed exchange rate system, the government or central bank sets and maintains the exchange rate at a predetermined level. This can provide more stability and predictability, but it also requires the government to actively manage the currency, which can be costly and may limit a country's ability to respond to changing economic conditions. The choice between a floating or fixed exchange rate system often depends on a country's economic goals, the strength of its economy, and its integration with the global financial system.
• Analyze the concept of purchasing power parity (PPP) and its implications for understanding the relative value of currencies and the comparison of living standards across countries.
  • Purchasing power parity (PPP) is a theory that suggests exchange rates should adjust to equalize the purchasing power of different currencies, allowing for a fair comparison of living standards across countries. The idea behind PPP is that the same basket of goods and services should cost the same in different countries when converted at the prevailing exchange rate. If a currency is undervalued relative to PPP, it suggests the country's goods and services are relatively cheap, and its citizens' purchasing power is higher than the exchange rate would indicate. Conversely, if a currency is overvalued relative to PPP, it suggests the country's goods and services are relatively expensive, and its citizens' purchasing power is lower than the exchange rate would suggest. By using PPP-adjusted exchange rates, economists can make more accurate comparisons of economic indicators, such as GDP per capita, across countries, providing a better understanding of the relative standard of living.
