# Profit maximizing price and quantity have a relationship

### Profit Maximisation | Economics Help

We have located the profit-maximizing level of output and price for a monopoly. How The Monopolist's Tradeoff between Price and Quantity There is a useful relationship between marginal revenue (MR) and the price elasticity of. An explanation of profit maximisation with diagrams - Profit max. But, to maximise profit, it involves setting a higher price and lower quantity than a competitive market Firms may also have other social objectives such as running the firm Domino Effect · Relationship between stock market and economy. The Profit Maximization Rule is that if a firm chooses to maximize its profits, words, they used the rule Marginal Revenue = Total Cost/quantity.

For example, the marginal revenue curve would have a negative gradient, because it would be based on the downward-sloping market demand curve. In an environment that is competitive but not perfectly so, more complicated profit maximization solutions involve the use of game theory.

Case in which maximizing revenue is equivalent[ edit ] In some cases a firm's demand and cost conditions are such that marginal profits are greater than zero for all levels of production up to a certain maximum. Marginal revenue equals zero when the total revenue curve has reached its maximum value. An example would be a scheduled airline flight.

The marginal costs of flying one more passenger on the flight are negligible until all the seats are filled. The airline would maximize profit by filling all the seats.

Profit Maximization

Changes in total costs and profit maximization[ edit ] A firm maximizes profit by operating where marginal revenue equals marginal cost. In the short run, a change in fixed costs has no effect on the profit maximizing output or price.

• Profit Maximisation

Using the diagram illustrating the total cost—total revenue perspective, the firm maximizes profit at the point where the slopes of the total cost line and total revenue line are equal. Consequently, the profit maximizing output would remain the same. This point can also be illustrated using the diagram for the marginal revenue—marginal cost perspective.

A change in fixed cost would have no effect on the position or shape of these curves. The profit maximization conditions can be expressed in a "more easily applicable" form or rule of thumb than the above perspectives use.

### The Economy: Leibniz: The profit-maximizing price

Close to Q1, MR is only just greater than MC; therefore, there is only a small increase in profit, but profit is still rising. However, after Q1, the marginal cost of the output is greater than the marginal revenue. This means the firm will see a fall in its profit level because the cost of these extra units is greater than revenue. This enables the firm to make supernormal profits green area.

Note, the firm could produce more and still make normal profit.

## Profit maximization

But, to maximise profit, it involves setting a higher price and lower quantity than a competitive market. Note, the firm could produce more and still make a normal profit.

Therefore, in a monopoly profit maximisation involves selling a lower quantity and at a higher price.

Diagram of monopoly Profit Maximisation in Perfect Competition In perfect competition, the same rule for profit maximisation still applies. Profit Maximisation in the Real World Limitations of Profit Maximisation In the real world, it is not so easy to know exactly your marginal revenue and the marginal cost of last goods sold.

For example, it is difficult for firms to know the price elasticity of demand for their good — which determines the MR.
