1. Monetary expansion can stimulate economic growth by increasing the availability of credit and liquidity in the financial system.
2. An expansionary monetary policy can lead to a decrease in interest rates, encouraging borrowing and investment by consumers and businesses.
3. Excessive monetary expansion can result in higher inflation, as the increased money supply chases a limited supply of goods and services.
4. The effects of monetary expansion on the economy can be influenced by factors such as the velocity of money and the public's expectations about future inflation.

Review Questions

• Explain how monetary expansion relates to Keynes' Law in the AD/AS model.
  • According to Keynes' Law, an increase in aggregate demand (AD) can lead to a corresponding increase in real output, at least in the short run. Monetary expansion, which increases the money supply, can be a key driver of increased aggregate demand. By lowering interest rates and making credit more accessible, monetary expansion encourages consumer spending and business investment, shifting the AD curve to the right. This, in turn, can lead to higher real GDP and employment levels, in line with Keynes' emphasis on the role of demand-side factors in determining economic output.
• Describe the relationship between monetary expansion and Say's Law in the AD/AS model.
  • Say's Law posits that the supply of goods creates its own demand, suggesting that the economy will naturally tend towards full employment equilibrium. However, monetary expansion can challenge this view by demonstrating that demand-side factors, such as an increase in the money supply, can influence the level of economic activity. Monetary expansion can shift the AD curve to the right, potentially leading to a new equilibrium with higher output and employment levels, even if the economy was initially at full employment. This highlights the importance of demand-side management, as advocated by Keynes, in contrast to the supply-side focus of Say's Law.
• Evaluate the potential consequences of excessive monetary expansion on the economy, particularly in the context of the AD/AS model.
  • Excessive monetary expansion can have significant consequences for the economy, as depicted in the AD/AS model. A rapid and sustained increase in the money supply can lead to a significant shift in the AD curve to the right, resulting in higher inflation and potentially overheating the economy. This can push the economy beyond its potential output level, leading to inflationary pressures and a loss of purchasing power for consumers. Additionally, if the central bank fails to manage the pace of monetary expansion effectively, it can undermine the credibility of monetary policy and lead to a loss of confidence in the currency, further exacerbating inflationary concerns. Striking the right balance between supporting economic growth and maintaining price stability is a critical challenge for policymakers when considering the appropriate degree of monetary expansion.
