Answer: Option A
Explanation: In simple words, substitution effect refers to the economic phenomenon which states that when price of one good rises the demand for the alternative of that particular good also rises. For example - coke and pepsi.
On the other hand, income effect states that when the price of a commodity rises, a number of consumers might find it hard to purchase due to the price exceeding their income power which further results in lower demand.
Hence from the above we can conclude that the correct option is A.
Answer:
the coefficient of elasticity is 1.25. therefore demand is elastic
Explanation:
Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.
Price elasticity of demand = percentage change in quantity demanded / percentage change in price
5% / 4% = 1.25
If the absolute value of price elasticity is greater than one, it means demand is elastic. Elastic demand means that quantity demanded is sensitive to price changes.
Demand is inelastic if a small change in price has little or no effect on quantity demanded. The absolute value of elasticity would be less than one
Demand is unit elastic if a small change in price has an equal and proportionate effect on quantity demanded
