Which one of the following gives the correct relationship between MR, AR and price elasticity?
Marginal revenue refers to the change in revenue or additional revenue which a firm earns on selling a unit more of its output. It is calculated by dividing the change in total revenue by change in total quantity of commodity sold.
Marginal revenue = Change in total revenue/ Change in quantity of commodity sold.
Average revenue is the revenue per unit of output sold in the market.
Average Revenue = total revenue/total quantity
Price elasticity of demand is the responsiveness of demand of a commodity towards change in its own price. It is denoted by e.
The relationship between these three is:
MR = AR {(e-1)/e} which denotes that MR is directly related to AR but change twice the proportion of AR whereas MR is inversely related to elasticity of demand.
