Long Descriptive Questions
- Explain the concept of ‘price elasticity of demand’ and how it affects revenue.
- Answer: Price elasticity of demand measures the responsiveness of the quantity demanded of a good to a change in its price. If demand is elastic (PED > 1), a price increase leads to a proportionally larger decrease in quantity demanded, reducing total revenue. If demand is inelastic (PED < 1), a price increase leads to a smaller decrease in quantity demanded, increasing total revenue.
- Discuss the role of central banks in controlling inflation through monetary policy.
- Answer: Central banks control inflation using tools such as interest rates, open market operations, and reserve requirements. By increasing interest rates, the central bank can reduce borrowing and spending, thereby reducing inflationary pressures. Open market operations involve buying and selling government securities to influence the money supply, while adjusting reserve requirements affects the amount of money banks can lend.
