What is midpoint elasticity (also known as arc elasticity)?

Midpoint elasticity is an alternate method of calculating elasticity.

Formula

\text{Midpoint Elasticity} = \frac{\frac{\text{Change in Quantity}}{\text{Average Quantity}}}{\frac{\text{Change in Price}}{\text{Average Price}}}

\text{Midpoint Elasticity} = \frac{\frac{\text{Q2 - Q1}}{\text{(Q2 * Q1) / 2}}}{\frac{\text{P2 - P1}}{\text{(P2 * P1) / 2}}}
