# Firms profit maximizing price and quantity have a relationship

The Profit Maximization Rule is that if a firm chooses to maximize its profits, words, they used the rule Marginal Revenue = Total Cost/quantity. price of the good times quantity Profit Maximization – Short Run pp. 0. Cost,. Revenue,. Profit. (\$s per year) Each firm is so small that its sales have no . What is the relationship between the elasticity of demand and markup? We have a measure of how much revenues change if output is increased—called When a firm changes its price, this leads to changes in revenues and costs. To the left of the point marked “profit-maximizing quantity,” marginal revenue exceeds.

## Profit maximization

Therefore, for this extra output, the firm is gaining more revenue than it is paying in costs, and total profit will increase.

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. 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.

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.

In a business setting, this is a critical concern. If a competitor decreases its price, this means that the demand curve you face will shift inward.

For example, suppose that British Airways decides to decrease its price for flights from New York to London. American Airlines will find that its demand curve for that route has shifted inward. If the demand curve shifts, should a firm change its price?

The answer is yes if the shift in the demand curve also leads to a change in the elasticity of demand. In practice, this is likely to be the case, although it is certainly possible for a demand curve to shift without a change in the elasticity of demand.

The correct response to a shift in the demand curve is to reestimate the elasticity of demand and then decide if a change in price is appropriate.

### Profit Maximisation | Economics Help

Complications Pricing is a difficult and delicate job, and there are many factors that we have not yet considered: We address some of them in other chapters of the book; others are topics for more advanced classes in economics and business strategy. By far the most important problem that we have neglected is as follows: When making pricing decisions, firms may need to take into account how other firms will respond to their decisions.

That calculation presumes that competing firms keep their prices unchanged. In markets with a small number of competitors, it is instead quite likely that other firms would respond by decreasing their prices.

We have assumed throughout that a firm has to charge the same price for every unit that it sells. In many cases, this is an accurate description of pricing behavior.

When a grocery store posts a price, that price holds for every unit on the shelf. But sometimes firms charge different prices for different units—by either charging different prices to different customers or offering individual units at different prices to the same customer. You have undoubtedly encountered examples. Firms sometimes offer quantity discounts, so the price is lower if you buy more units. Sometimes they offer discounts to certain groups of customers, such as cheap movie tickets for students.

We could easily fill an entire chapter with other examples—some of which are remarkably sophisticated. Firms can have pricing strategies that call for the price to change over time.

For example, firms sometimes engage in a strategy known as penetration pricing, whereby they start off by charging a low price in an attempt to develop or expand the market.

It might decide to offer the cereal at a low price to induce people to try the product.

Only after it has developed a group of loyal customers would it start setting their prices according to the markup principle. Pricing plays a role in the overall marketing and branding strategy of a firm. Some firms position themselves in the marketplace as suppliers of high-end offerings. They may choose to set high prices for their products to ensure that customers perceive them appropriately. Consider a luxury hotel that is contemplating setting a very low price in the off-season.

Psychologists who study marketing have found that demand is sensitive at certain price points. Such consumer behavior does not seem completely rational, but there is little doubt that it is a real phenomenon.

Throughout this chapter, we have said that there is no difference between a firm choosing its price and taking as given the implied quantity or choosing its quantity and taking as given the implied price. Either way, the firm is picking a point on the demand curve. This is true, but there is a footnote that we should add. See Chapter 14 "Busting Up Monopolies" for discussion of this.

We should also note that firms often do not know their demand curves with complete certainty. If the firm sets the price, it will end up with an unexpectedly large quantity being demanded. If the firm sets the quantity, it will end up with an unexpectedly high price. We have focused our attention on the market power of firms as sellers, as reflected in the downward-sloping demand curves they face.

Firms can also have market power as buyers. Walmart is such an important customer for many of its suppliers that it can use its position to negotiate lower prices for the goods it buys.

Governments are also often powerful buyers and may be able to influence the prices they pay for goods and services. For example, government-run health-care systems may be able to negotiate favorable prices with pharmaceutical companies. Key Takeaways At the profit-maximizing price, marginal revenue equals marginal cost.
