8. The conclusion that an increase in the money supply will lead to lower interest rates is based on which of the following effects?
Answer: D
The conclusion that an increase in the money supply will lead to lower interest rates is based on the liquidity preference effect.
An increase in the money supply typically results in lower interest rates due to the liquidity preference effect, which suggests that as more money is available in the economy, people prefer holding onto liquidity, reducing the cost of borrowing.
A) Real price level
The real price level refers to the value of goods and services adjusted for inflation. While changes in the money supply can influence price levels over time, this option does not directly explain the relationship between money supply and interest rates, making it incorrect in this context.
B) Expected inflation
Expected inflation can influence interest rates, as lenders demand higher rates to compensate for anticipated decreases in purchasing power. However, this explanation does not directly link the increase in money supply to lower interest rates, focusing instead on inflationary expectations rather than liquidity.
C) Income stabilization
Income stabilization relates to maintaining consistent income levels within the economy. While a change in the money supply can impact overall economic activity and income levels, this option does not address the mechanism through which an increase in the money supply leads to lower interest rates, making it an incorrect choice.
D) Liquidity preference
The liquidity preference theory posits that as the money supply increases, the demand for liquidity rises, leading to lower interest rates. This relationship directly supports the conclusion that an increase in the money supply will result in lower borrowing costs, making this the correct answer.
Conclusion
The liquidity preference effect provides the most direct explanation for why an increase in the money supply leads to lower interest rates. Other options, such as real price level, expected inflation, and income stabilization, do not adequately explain this relationship, thus confirming that D is the definitive correct choice.
