Q4. Consider the following statements: (UPSC CSE 2021)
Other things remaining unchanged, market demand for a good might increase if
- price of its substitute increases
- price of its complement increases
- the good is an inferior good and income of the consumers increases
- its price falls
Which of the above statements are correct?
- 1 and 4 only
- 2, 3 and 4
- 1, 3 and 4
- 1, 2 and 3
Answer: A
Explanation
- Statement 1 is correct: When the price of a substitute rises, consumers tend to shift away from the relatively costlier substitute and increase consumption of the given good, leading to a rise in its market demand.
- Statement 2 is incorrect.: An increase in the price of a complementary good reduces the joint consumption of both goods, thereby decreasing the demand for the given good rather than increasing it.
- Statement 3 is incorrect.: In the case of an inferior good, an increase in consumers’ income leads to a decline in its demand as consumers shift towards superior goods.
- Statement 4 is correct: As per the law of demand, a fall in the price of a good results in an increase in quantity demanded, which increases its market demand.
