UPSC CSP 2021 — What Shifts Market Demand for a Good
- UPSC 2021 The correct answer is (a) 1 and 4 only. A pricier substitute pushes buyers toward this good, raising its demand. A price fall for the good itself also raises the quantity demanded. A pricier complement lowers demand for this good, it doesn’t raise it. For an inferior good, higher income lowers demand too, so statement 3 gets the direction backwards. See UPSC CSP 2021 GS Paper I, Q4.
