Review Questions
How does currency function as a medium of exchange in an economy?
Currency functions as a medium of exchange by providing a standardized way for people to trade goods and services without the need for bartering. This simplifies transactions because individuals do not need to find someone who has what they want and who also wants what they have. The use of currency facilitates commerce by allowing for easier price comparison and establishing consistent values for products, thereby enhancing economic efficiency.
Discuss how changes in monetary policy can impact the value of currency.
Changes in monetary policy can significantly impact the value of currency by altering interest rates and influencing inflation. For instance, if a central bank lowers interest rates, it may lead to an increase in money supply which can depreciate the currency's value. Conversely, raising interest rates can strengthen the currency by attracting foreign investment, as higher returns on investments make that currency more appealing. This relationship demonstrates how monetary policy plays a crucial role in stabilizing or destabilizing a currency's value within an economy.
Evaluate the implications of having multiple currencies within international trade on global economic stability.
Having multiple currencies in international trade can create complexities that affect global economic stability through fluctuations in exchange rates. Variations in currency values can lead to competitive advantages or disadvantages among countries, influencing trade balances and investment flows. Additionally, if currencies are volatile, it can lead to uncertainty for businesses engaging in cross-border transactions. This instability may deter investment and hinder economic growth as firms face challenges in forecasting costs and revenues when dealing with multiple currencies.
