Calculate price elasticity using the midpoint method. Differentiate between slope and elasticity. Figure 1. Just how elastic is it? We have defined price elasticity of demand as the responsiveness of the quantity demanded to a change in the price.
Price elasticity of demand on certain interval of graph = percentage of change of quantity demanded over interval / percentage of change of price over interval. Note: price elasticity is not the same as slope. Slope remains the same on a straight line graph but elasticity changes.
To calculate elasticity, instead of using simple percentage changes in quantity and price, economists sometimes use the average percent change in both quantity and price. This is called the Midpoint Method for Elasticity:
24 wrz 2020 · Midpoint elasticity is an alternate method of calculating elasticity. Formula – How to calculate Arc Elasticity. Midpoint Elasticity = (Change in Quantity / Average Quantity) / (Change in Price / Average Price) Change in Quantity = Q2 – Q1. Average Quantity = (Q1 + Q2) / 2. Change in Price = P2 – P1. Average Price = (P1 + P2) / 2. Example.
