Long Descriptive Questions
- Explain the law of demand with the help of a graph.
- Answer: The law of demand states that, all else equal, as the price of a good or service decreases, the quantity demanded increases. This relationship is typically depicted as a downward-sloping demand curve on a graph, where price is on the vertical axis and quantity demanded is on the horizontal axis.
- Discuss the various types of unemployment and their causes.
- Answer: Unemployment can be classified into four types: frictional, structural, cyclical, and seasonal. Frictional unemployment occurs when workers are between jobs. Structural unemployment arises due to technological changes or shifts in demand for certain skills. Cyclical unemployment is caused by economic downturns, and seasonal unemployment occurs due to changes in demand during different times of the year.

- Answer: Central banks control inflation by managing the money supply and interest rates. By increasing interest rates, they reduce borrowing and spending, which helps cool down an overheated economy. They can also use open market operations to buy or sell government securities to control liquidity in the economy.

demand and its types.**
- Answer: Elasticity of demand measures how much the quantity demanded of a good changes in response to a price change. There are three types: price elasticity of demand (PED), income elasticity of demand (YED), and cross-price elasticity of demand (XED). PED measures responsiveness to price changes, YED to changes in income, and XED to changes in the price of related goods.
