Long Descriptive Questions

1. Explain the concept of ‘elasticity of demand’ and its types.
   • Answer: Elasticity of demand refers to the responsiveness of the quantity demanded of a good to a change in its price. There are three types: price elasticity of demand (PED), income elasticity of demand (YED), and cross-price elasticity of demand (XED). PED measures the responsiveness of demand to a change in the price of the good itself. YED measures the responsiveness of demand to a change in consumer income, while XED measures how the demand for one good responds to a price change of another good.
2. Discuss the different types of unemployment and their economic implications.
   • Answer: Unemployment is categorized into frictional, structural, cyclical, and seasonal types. Frictional unemployment occurs when workers are between jobs. Structural unemployment arises due to shifts in the economy that change the demand for specific skills. Cyclical unemployment is linked to the business cycle, typically during recessions. Seasonal unemployment occurs

when demand for labor varies by season.

3. Analyze the role of government in the economy through fiscal policy.
   • Answer: Fiscal policy involves government spending and taxation decisions that affect economic activity. An expansionary fiscal policy, which involves increased government spending or tax cuts, is used to stimulate economic growth, especially during recessions. Conversely, a contractionary fiscal policy, involving reduced spending or increased taxes, is used to control inflation.
