Question

Suppose that a demand curve exhibits two points. Initially, at price P 0 P0 , the quantity demanded is Q 0 Q0 . When price changes to P 1 P1 , quantity demanded is Q 1 Q1 . Move the components of the midpoint formula for elasticity of demand to their correct positions.

Answer 1

Answer:

$Price Elasticity of Demand= \frac{Percentage change in Demand}{Percentage change in Price}$

At Price = $P_{0}$

Quantity demanded = $Q_{0}$

At Price = $P_{1}$

Quantity Demanded = $Q_{1}$

Now,

$Percentage change in Demand = \frac{(Q_{1} - Q_{0})}{Q_{0}}$

$Percentage change in Price = \frac{(P_{1} - P_{0})}{P_{0}}$

$Price Elasticity of Demand = \frac{\frac{(Q_{1} - Q_{0})}{Q_{0}}}{\frac{(P_{1} - P_{0})}{P_{0}}}$

Above formula if used will give the correct answer related to Price Elasticity of Demand.

Another variant of above formula is also being used on prominent basis.

$Price Elasticity of Demand = \frac{\frac{(Q_{1} - Q_{0})}{(Q_{1} + Q_{0})} }{\frac{(P_{1} - P_{0})}{P_{1} + P_{0}} }$

Utilization of any of the above Formula will give the ideal outcome in estimating Price elasticity of demand.
