Derivation of TR, AR and MR curves under monopoly market - Reference Notes
For a monopolist, both marginal revenue and demand are downward-sloping curves. Marginal revenue will always be less than demand for a given quantity. The relationship between the average and MR curves in monopoly is shown in diagram. Aa a monopolist's demand curve slopes downward to. However, the true relationship between the AR curve and its corresponding MR curve under monopoly or imperfect competition depends upon the elasticity of.
A monopolist can set its price and automatically sell to every customer who is willing to buy at that price, because a monopolist has no competition. On one hand, this means the monopolist can make significant profits, but on the other hand the monopolist is at the mercy of consumers when it comes to determining price and quantity -- the monopolist picks only one, and the customers determine the other.
Average Revenue For any company, average revenue is the total revenue of the company divided by the quantity of goods sold -- this can be interpreted as revenue per unit.
For a monopolist, this is the same as the demand curve. Average revenue for a monopolist consists of the price per unit, because a monopolist captures the entire market at a given level of output.
The monopolist must decrease prices if it wants to sell any more of its goods, because at any level of prices it has already sold to every customer willing to buy.
The only new customers in the market who have not bought the product are those farther down the demand curve, who only buy when the price is lower. However, the true relationship between the AR curve and its corresponding MR curve under monopoly or imperfect competition depends upon the elasticity of the AR curve.
Relationship between Average and Marginal Revenue Curves | Owlcation
At point B on the average revenue curve, PA, the elasticity of demand is equal to 1. Thus, where elasticity of AR curve is unity, MR is always zero In case the elasticity of the AR curve is unity throughout its length like a rectangular hyperbola, the MR curve will coincide with the X-axis, shown as a dotted line in Figure 5 B.
It shows that when the elasticity of AR is greater than one, MR is always positive. It is EH in Figure 5 A.
Derivation of TR, AR and MR curves under monopoly market
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. Marginal Equals Average Perfect Competition The equality between average revenue and marginal revenue occurs for a firm selling an output in a perfectly competitive market.
This is illustrated by the exhibit to the right. 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.

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. The equality between marginal revenue and average revenue is the result of perfect competition.
Relationship between AR and MR Curves
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.
