Question

In macroeconomic analysis, how does an economy behave when it enters a state known as a 'Liquidity Trap'?

• A. The interest rate drops to an extremely low level, making the speculative demand for money infinitely elastic as people prefer to hoard cash.
• B. The transactional demand for money drops to zero because economic activity stops completely.
• C. Commercial banks experience an acute shortage of liquid cash reserves, causing lending to drop sharply.
• D. The central bank loses its legal authority to issue new currency notes into circulation.

Hint:

In a liquidity trap, the opportunity cost of holding money becomes almost zero, so people prefer to hoard cash instead of investing in bonds or securities.

Answer 1

The Correct Option is A

Concept: According to Keynesian theory, the speculative demand for money depends inversely on the rate of interest. When interest rates are high, people prefer to invest in bonds and securities. When interest rates become extremely low, people expect them to rise in the future, which may reduce bond prices and create capital losses. Therefore, individuals prefer to hold cash instead of purchasing bonds.

Step 1: Understand the behavior of interest rates in a liquidity trap.
A liquidity trap occurs when the rate of interest falls to a very low level. At this stage: \[ \text{Interest Rate} \downarrow \] and people believe that interest rates cannot fall further. Because bond prices and interest rates move inversely, people expect bond prices to fall in the future. Hence, they avoid investing in bonds and prefer to hold liquid cash balances.

Step 2: Analyze the speculative demand for money.
In a liquidity trap, the speculative demand for money becomes highly elastic or infinitely elastic. This means that any additional money supplied by the central bank is simply hoarded by the public rather than being invested or spent. Thus: \[ \text{Additional Money Supply} \rightarrow \text{Cash Hoarding} \] As a result, expansionary monetary policy becomes ineffective in stimulating investment and economic activity.

Step 3: Evaluate the options.

• [(A)] Correct — This accurately describes a liquidity trap situation.
• [(B)] Incorrect — Transactional demand for money never becomes zero.
• [(C)] Incorrect — A liquidity trap is related to interest rates and speculative demand, not shortage of bank reserves.
• [(D)] Incorrect — The central bank does not lose its legal authority to issue currency.

Hence, the correct answer is: \[ \boxed{\text{(A)}} \]
