The Mid point forumula for Price Elasticity of Demand

Описание к видео The Mid point forumula for Price Elasticity of Demand

Why do we always get a different value for a good's elasticity of demand depending on whether the price increases or decreases? Well, if you're finding this result, you're probably using the simple elasticity formula. This lesson introduces the "mid-point" formula for calculating price elasticity of demand, which eliminates the problem of arriving at two different elasticity values between the same two prices depending on whether price is rising or falling.
