mathematical relationship between average revenue and marginal

Learn about the relationship between AR and MR Curves. The relation between average revenue and marginal revenue can be discussed under pure. The relationship among total, average and marginal revenues under is given by the total revenue (TR), average revenue (AR) and marginal revenue (MR). Here are explanations of the relationship between average and marginal costs and of average cost variations and marginal cost of a natural.

It shows that when the elasticity of AR is greater than one, MR is always positive.

The Average Revenue, Marginal Revenue and Price Elasticity of Demand

It is EH in Figure 5 A. It shows MR to be negative. Under monopolistic competition, the relationship between AR and MR is the same as under monopoly. But there is an exception that the AR curve is more elastic, as shown in Figure 6.

The firm can increase its sales by a reduction in its price. The average and marginal revenue curves do not have a smooth downward slope under oligopoly. Since the number of sellers under oligopoly is small, the effect of a price cut or price increase on the part of one seller will be followed by some changes in the behaviour of other firms.

The Average Revenue, Marginal Revenue and Price Elasticity of Demand

If a seller raises the price of his product, the other sellers will not follow him in order to earn larger profits at the old price. This exhibit contains the average revenue curve and marginal revenue curve for zucchini sold by Phil the zucchini grower, a hypothetical firm in Shady Valley.

mathematical relationship between average revenue and marginal

Phil the zucchini grower is one of thousands of zucchini growers in the market, selling identical products. As such, Phil receives the going price for zucchini. The primary observation from this exhibit is that apparently only one curve is displayed. They appear to be one curve because each overlays the other. They coincide because marginal revenue is equal to average revenue at every output quantity.

Relationship between Average and Marginal Revenue Curves

The equality between marginal revenue and average revenue is the result of perfect competition. Because Phil receives the same per unit price for every worker, incremental revenue is equal to the per unit revenue.

Marginal Less Than Average Monopoly Marginal revenue falling short of average revenue occurs for a firm selling an output in a monopoly market. This exhibit contains the average revenue curve and marginal revenue curve for medicine sold another hypothetical firm, Feet-First Pharmaceutical. By virtue of a government patent, Feet-First Pharmaceutical is the only producer of Amblathan-Plus, the only cure for the deadly but hypothetical foot ailment known as amblathanitis. As the only producer, Feet-First is a monopoly with extensive market control, and it faces a negatively-sloped demand curve.

The primary observation from this exhibit is that the negatively-sloped marginal revenue curve lies below the negatively-sloped average revenue curve.

We, thus, observe that with the increase in sales, price falls and marginal revenue is less than the price or AR. That is why, the MR curve lies below the AR curve and declines at a faster rate. It is important to note that the falling MR curve bisects the distance on the X-axis between the point of origin and the point, where the AR curve touches the X-axis in two equal parts.

But, this relationship will not hold true, if the AR curve is not a straight line that slopes downward. It may be further observed that so long as the TR is increasing, MR is positive. Thus, TR curve starting from the origin continues to increase up to five units. TR does not change between fifth and sixth unit.

  • Relationship between AR and MR Curves

When TR is unaffected by the increase in quantity, MR is equal to zero. TR is maximum corresponding to zero MR at the sixth unit.

Beyond sixth unit, TR falls and MR becomes negative.
