ESSAY QUESTIONS
ANS:
The price elasticity of demand measures buyer responsiveness to a price change. If the price elasticity of demand coefficient equals 1.2, this means that for every 1 percent change in price there will be a 1.2 percent change in the quantity demanded in the opposite direction. This implies that consumers are relatively responsive to a change in the price and therefore the demand for this product is elastic.
ANS:
Total revenue will rise if the price rises and demand is inelastic. This is because the percentage increase in the price exceeds the percentage decrease in the quantity demanded. Indeed, whenever, the demand is inelastic this means buyers are relatively unresponsive to a change in the price. Therefore, total revenue rises when price rises.
ANS:
A product that has an inelastic demand has few substitutes, accounts for a relatively small share of buyers’ budget, and there is a relatively short time frame under consideration.
