Why Prices Get Sticky When the Economy is Headed for The relationship between marginal revenue and the price elasticity of demand is: Maximizing profit requires marginal revenue equals marginal cost, so is a negative number because an inverse relationship exists between price and quantity demanded.

## Profit Maximisation

However, firms can make a best estimation. Many firms may have to seek profit maximisation through trial and error. Demand may change due to many other factors apart from price. Firms may also have other objectives and considerations.

For example, increasing price to maximise profits in the short run could encourage more firms to enter the market; therefore firms may decide to make less than maximum profits and pursue a higher market share.

Firms may also have other social objectives such as running the firm like a cooperative — to maximise the welfare of stakeholders consumers, workers, suppliers and not just profit of owners. This occurs when there is separation of ownership and control and where managers do enough to keep owners happy but then maximise other objectives such as enjoying work. But if you change the price, both marginal cost and the elasticity of demand are also likely to change.

A more reliable way of using this formula is in the algorithm shown in Figure 6. The five steps are as follows: At your current price, estimate marginal cost and the elasticity of demand. Calculate the optimal price based on those values. If the optimal price is greater than your actual price, increase your price. Then estimate marginal cost and the elasticity again and repeat the process. If the optimal price is less than your actual price, decrease your price. If the current price is equal to this optimal price, leave your price unchanged.

They had found that based on current marginal cost and elasticity, the price could be raised. But as they raised the price, they knew that the elasticity of demand would probably also change. An elasticity of 2 means that the markup should be percent to maximize profits.

Shifts in the Demand Curve Facing a Firm So far we have looked only at movements along the demand curve—that is, we have looked at how changes in price lead to changes in the quantity that customers will buy. Firms also need to understand what factors might cause their demand curve to shift.

Among the most important are the following: Changes in household tastes. Starting around or so, low-carbohydrate diets started to become very popular in the United States and elsewhere. For some companies, this was a boon; for others it was a problem.

For example, companies like Einstein Bros. As more and more customers started looking for low-carb alternatives, these firms saw their demand curve shift inward. Consider Lexus, a manufacturer of high-end automobiles. When the economy is booming, sales are likely to be very good.

In boom times, people feel richer and more secure and are more likely to purchase a luxury car. But if the economy goes into recession, potential car buyers will start looking at cheaper cars or may decide to defer their purchase altogether. Many companies sell products that are sensitive to the state of the business cycle.

Their demand curves shift as the economy moves from boom to recession. 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.

The airline would maximize profit by filling all the seats. 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. 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 additional units are called the marginal units.
