Question 10

Liquidity preference explains why an increase in the money supply results in a decrease in interest rates.

The liquidity preference theory posits that when the money supply increases, people have more funds available, leading to lower interest rates as the demand for money balances adjusts to the increased supply.

A) Real price level

The real price level refers to the price of goods and services adjusted for inflation. While it can influence economic conditions, it does not directly explain the relationship between money supply and interest rates. An increase in the real price level may affect purchasing power but does not account for changes in liquidity preference.

B) Liquidity preference

This concept is directly related to the question. According to liquidity preference theory, an increase in the money supply enhances the availability of funds, lowering the cost of borrowing, which is reflected in decreased interest rates. This is because individuals and businesses are more willing to hold onto liquid assets when there is more money available in the economy.

C) Income stabilization

Income stabilization refers to measures aimed at maintaining consistent income levels, which can influence economic activity. However, it does not specifically address the mechanisms by which an increase in the money supply affects interest rates. Therefore, it is not relevant to the question at hand.

D) Expected inflation

Expected inflation relates to the anticipation of price increases in the future. While it can influence interest rates, an increase in the money supply primarily affects interest rates through liquidity preference rather than expected inflation directly. Increased liquidity tends to lower interest rates before any inflationary expectations come into play.

Conclusion

Liquidity preference is the key concept that explains the inverse relationship between money supply and interest rates. While the other options touch on relevant economic themes, they do not adequately capture the mechanism of how an increased money supply leads to lower interest rates, making liquidity preference the definitive choice in this context.
