Frequently Asked Questions
121. What is Supply and Demand, and why is it a fundamental concept for UPSC GS Paper 3?
Supply and Demand is a core economic principle that explains the relationship between the quantity of a good or service producers are willing to offer (supply) and the quantity consumers are willing to purchase (demand). Their interaction determines the market price and quantity. It's fundamental for UPSC GS Paper 3 because it underlies the analysis of inflation, market interventions, and economic growth.
Exam Tip
Remember that Supply and Demand is the foundation for understanding many economic issues. Focus on factors that shift the curves.
2. Explain the Law of Demand and the Law of Supply. How do they interact to determine the equilibrium price?
The Law of Demand states that as the price of a good or service increases, the quantity demanded decreases (inverse relationship). The Law of Supply states that as the price increases, the quantity supplied increases (direct relationship). The equilibrium price is the point where the quantity demanded equals the quantity supplied, representing a market-clearing price.
