- (ख)) Based on the information given below, calculate the price elasticity of demand and cross elasticity of demand: Qd=10-2P+Ps. Here Qd = Quantity demanded of a commodity; P = Price of the commodity given as Rs 10; Ps = Price of the substitute commodity given as Rs 20. (250 words)
- Law of Demand: Qualitative statement, inverse relationship between price and quantity demanded (ceteris paribus).
- Price Elasticity of Demand (PED): Quantitative measure of responsiveness of quantity demanded to price changes.
- Factors determining PED: Availability of substitutes, nature of good, proportion of income spent, and time period.
- Elasticity aids firms in pricing strategies and governments in taxation for revenue or consumption control.
Answer: The provided question delves into fundamental concepts of microeconomics, specifically differentiating between the qualitative statement of the law of demand and the quantitative measure of price elasticity of demand. It also explores the determinants of price elasticity and its critical role in decision-making for various economic agents. Furthermore, it requires the application of these concepts to calculate price and cross elasticity using a given demand function, illustrating how theoretical...
