Step 1: Understanding the Concept:
A Liquidity Trap is a situation described by Keynesian economics where monetary policy becomes ineffective.
It occurs when interest rates are so low that they cannot fall any further.
At this point, the public expects interest rates to rise in the future, which would cause bond prices to fall (there is an inverse relationship between interest rates and bond prices).
Step 2: Detailed Explanation:
In a liquidity trap:
1. Interest Rates are Near Zero: The rate of return on alternative assets like bonds is so low that there is no incentive to hold them.
2. Speculative Demand for Money: People hold money for speculation, hoping to buy assets when prices fall. In a trap, because people expect rates to rise later, they believe bond prices are currently at a "ceiling" and will soon drop.
3. Infinite Elasticity: Because people are certain rates won't go lower, any new money injected by the Central Bank into the economy is simply "hoarded" as cash. The demand for money becomes horizontal (infinitely elastic).
4. Failure of Policy: Since any increase in money supply is hoarded, it fails to lower interest rates further or stimulate investment. The economy is "trapped" in stagnation.
Analysis of options:
- Option (B) is wrong; people still need money for transactions.
- Option (C) is wrong; the problem is not a lack of supply of money, but a lack of demand for investment.
- Option (D) is irrelevant to the economic definition of a trap.
Step 3: Final Answer:
A liquidity trap is defined by extremely low interest rates and infinitely elastic speculative demand for money.
Thus, Option (A) is correct.
