Q & A

What is the relationship between money supply and money demand in an economy?

Money supply refers to the total amount of money available in the economy, which can be influenced by central banks. Money demand refers to the public’s desire to hold money in liquid form, which is affected by factors like interest rates and income levels. The interaction between the two determines the equilibrium level of money circulating in the economy.

How does the movement of interest rates affect money demand?

As interest rates rise, the opportunity cost of holding money increases because people can earn higher returns from saving or investing. Consequently, money demand decreases. Conversely, lower interest rates encourage people to hold more money since the opportunity cost is lower.

What is the role of central banks in controlling money supply?

Central banks regulate money supply through monetary policy, often by adjusting the amount of money circulating in the economy. This can be done through mechanisms like open market operations, setting interest rates, or adjusting reserve requirements for commercial banks.

What are the three main motives for money demand mentioned in the script?

The three main motives for money demand are: (1) Transaction motive: holding money for day-to-day purchases, (2) Precautionary motive: holding money for unexpected needs, and (3) Speculative motive: holding money in anticipation of future investment opportunities, typically when interest rates are low.

How does income affect money demand according to the script?

As income increases, the demand for money also increases, particularly for transaction and precautionary purposes. With higher income, individuals and businesses tend to require more money for everyday activities and unexpected expenses.

What does the money supply curve typically look like, and why?

The money supply curve is typically vertical, indicating that the supply of money is not directly influenced by interest rates in the short term. Instead, it is determined by central bank policy, which sets a fixed amount of money in circulation.

What happens when the central bank increases the money supply?

When the central bank increases the money supply, the money supply curve shifts to the right. This can be done through actions like buying assets or injecting liquidity into the banking system, which increases the overall money available in the economy.

What is the opportunity cost of holding money, and how does it relate to interest rates?

The opportunity cost of holding money refers to the potential returns an individual forgoes by not investing or saving the money elsewhere. As interest rates rise, the opportunity cost of holding money increases, making people less inclined to hold money in liquid form.

How does the money demand curve behave with changing interest rates?

The money demand curve generally slopes downward, meaning that as interest rates rise, the quantity of money demanded decreases. This reflects the inverse relationship between interest rates and money demand, where higher rates make holding money less attractive.

Can the central bank influence both the supply and demand for money in the economy?

While the central bank can directly influence the supply of money through policy tools like setting interest rates and controlling liquidity, it has less direct control over money demand. However, the central bank can indirectly affect money demand by adjusting interest rates, which impacts how much people are willing to hold money.
