Question

If the quantity of a commodity demanded remains unchanged as its price changes, the coefficient of price elasticity of demand is....​

Answer 1

Answer:

The demand for a commodity becomes unitary elastic when the rate of change in the price and that in the quantity demanded become the same. It is neither elastic nor inelastic; it occupies a middle position between the two. Here, the elasticity of demand is equal to (negative) one or unity.

Answer 2

If the quantity of a commodity demanded remains unchanged as its price changes, the coefficient of price elasticity of demand is zero.

1. It is the case of perfectly inelastic demand.
2. it is a parallel to y-axis demand curve.
3. It implies whatever price maybe charged from the consumer, the quantity of consumption will remain the same.
