# Relationship between ar and mr curve

### The Relationship between Different Revenue Concepts | Economics It means, the revenue from every additional unit (MR) is equal to AR. As a result, both AR and MR curves coincide in a horizontal straight line parallel to the. Learn about the relationship between AR and MR Curves. The relation between average revenue and marginal revenue can be discussed under pure. A mathematical connection between average revenue and marginal revenue labeled MR = AR, is actually two curves, the marginal revenue curve and the.

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. 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.

The juxtaposition of these two curves illustrates the marginal less than average relation. Because the marginal revenue is less than average revenue, the average revenue curve decreases. Because Feet-First Pharmaceutical has market control and faces a negatively-sloped factor demand curve it must charge a lower price to sell more Amblathan-Plus. Suppose, for example, that Feet-First Pharmaceutical wants to increase the quantity of Amblathan-Plus sold from 4 to 5 ounces. However, the lower price is charged to all buyers.

### The Relationship between Average and Marginal Revenue

What happens to Feet-First Pharmaceutical's total revenue when it lowers the price? Two forces are at work: Marginal revenue is the net result of both. First, by lowering its price, Feet-First Pharmaceutical increases the quantity sold from 4 ounces to 5 ounces. Second, by lowering its price, Feet-First Pharmaceutical collects less revenue from its other 4 ounces. The average revenue curve is the downward sloping industry demand curve and its corresponding marginal revenue curve lies below it.

The relation between the average revenue and the marginal revenue under monopoly can be understood with the help of Table 2.

## The Relationship between Different Revenue Concepts | Economics

The marginal revenue is lower than the average revenue. Given the demand for his product, the monopolist can increase his sales by lowering the price, marginal revenue also falls but the rate of fall in marginal revenue is greater than that in average revenue In Table 2 AR falls by Rs. This relation will always exist between straight line downward slopping AR and MR curves. In case the AR curve is convex to the origin as in Figure 3 Athe MR curve will cut any perpendicular from a point on the AR curve at more than half-way to the Y-axis.

### Relationship between AR and MR Curves

On the other hand, if the AR curve is concave to the origin, MR will cut the perpendicular at less than half-way towards the Y-axis. AR, MR and Elasticity: 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. 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.
