Exchange rates

Definition

Exchange rates are the values at which one currency can be exchanged for another, reflecting the relative strength of currencies in the foreign exchange market. They play a crucial role in international trade and finance by determining how much of one currency is needed to purchase a unit of another currency, impacting economic stability, inflation, and investment decisions.

1. Exchange rates can fluctuate based on various factors including interest rates, economic indicators, political stability, and market speculation.
2. Keynes believed that exchange rates should be more stable to promote international trade and economic growth, arguing against extreme volatility.
3. Floating exchange rates fluctuate freely based on market forces, while fixed exchange rates are maintained by government intervention.
4. Changes in exchange rates can directly impact the prices of imports and exports, influencing inflation and economic policy decisions.
5. The concept of purchasing power parity (PPP) is often used to assess whether currencies are undervalued or overvalued compared to each other.

Review Questions

• How do fluctuations in exchange rates affect international trade and investment decisions?
  • Fluctuations in exchange rates can significantly impact international trade by altering the cost of goods and services across borders. For instance, if a country's currency depreciates, its exports become cheaper for foreign buyers, potentially increasing demand. Conversely, imports become more expensive, which can lead to reduced consumption of foreign goods. These changes affect businesses' investment strategies as they consider potential returns and risks associated with varying currency values.
• Analyze how John Maynard Keynes' views on exchange rate stability might influence modern economic policies.
  • Keynes advocated for stable exchange rates to minimize uncertainty in international trade and investment. His ideas suggest that governments should actively manage their currencies to prevent extreme volatility that could disrupt economic growth. Modern economic policies may reflect this by implementing measures such as currency pegs or interventions in the foreign exchange market during times of instability, aiming to create a predictable environment for trade and investment.
• Evaluate the implications of adopting a fixed versus a floating exchange rate system in relation to Keynesian economics.
  • In evaluating fixed versus floating exchange rate systems through the lens of Keynesian economics, one sees that a fixed rate can provide stability conducive to trade but may limit a government's ability to respond to domestic economic changes. Conversely, a floating rate allows for more flexibility in monetary policy but can lead to instability that Keynes argued against. The choice between these systems reflects broader economic priorities: prioritizing stability and predictability or adapting rapidly to market conditions while managing potential risks associated with currency fluctuations.
