The deadweight loss equals the change in price multiplied by the change in quantity demanded. This equation is used to determine the cause of inefficiency within a market. However, if one producer has a monopoly on nails they will charge whatever price will bring the largest profit. When equilibrium is not achieved, parties who would have willingly entered the market are excluded due to the non-market price.
An example of deadweight loss due to taxation involves the price set on wine and beer. At times, policy makers will place a binding constraint on items when they believe that the benefit from the transfer of surplus outweighs the adverse impact of deadweight loss. Deadweight loss : This graph shows the deadweight loss that is the result of a binding price ceiling. Policy makers will place a binding price ceiling when they believe that the benefit from the transfer of surplus outweighs the adverse impact of the deadweight loss.

Reasons for Efficiency Loss A monopoly generates less surplus and is less efficient than a competitive market, and therefore results in deadweight loss. Learning Objectives Evaluate the economic inefficiency created by monopolies.
Key Takeaways Key Points The monopoly pricing creates a deadweight loss because the firm forgoes transactions with the consumers. Key Terms monopoly : A market where one company is the sole supplier. Understanding and Finding the Deadweight Loss In economics, deadweight loss is a loss of economic efficiency that occurs when equilibrium for a good or service is not Pareto optimal.
Whenever there is variety, and hence some amount of brand loyalty, firms will have some market power, i. So, the cost of variety is that firms will have some degree of pricing power.
But the benefit is a wide variety of goods to choose from. Consumers certainly seem to have a taste for variety, so this benefit must be weighed against the market power that companies get from differentiated products.
As long as the number of firms in an industry is relatively large, making a market "monopolistically competitive," it's likely that the benefits of variety will outweigh the cost. However, when the number of firms is smaller so that oligopolies a few dominant firms or monopolies a single dominant firm appear, the likelihood that the benefits outweigh the costs is substantially diminished and scrutiny from regulators is needed.
One case where scrutiny is certainly needed is one economists call a "natural monopolies. It happens naturally, often because of economies of scale that are still in effect even after the entirety of market demand has been satisfied.
Because the monopoly power cannot be prevented by regulating the firm's strategic behavior, and because breaking it up would often result in higher costs and hence higher prices for consumers, the best course of action is to regulate the prices and quantities such a company can charge.
A firm's size and market share do not necessarily indicate that it is exploiting its market power or that substantial market share even exists.
A dominant firm in an industry could, for example, face substantial new entrants and competition if it attempts to raise its prices and exploit its dominant position in the marketplace. But firms that exploit their market power or undertake strategic behaviors that make it more difficult for other companies to compete should come under the careful watch and, when appropriate, receive penalties from regulators charged with promoting the public interest.
If my product is good enough, then I want to gain a monopoly. If we interfere with this, there is a danger that miss out on the best technology at the best price, and we perhaps even discourage entrepreneurs from trying to start new companies if they know they cannot profit from it. It is the very nature of businesses and their limited resources that they become specialists, and this is what monopolists do. Read More: How business can meet the challenge of climate change.
Over time, we see empirical evidence for large companies becoming ever more commercial but also declining innovation over time see for example, Markides and Geroski, This is how most industries are organised, and this is the trend that we have seen throughout the past century. Entrepreneurs are also motivated to sell their new technology and move on to something new, rather than being responsible for the daily running of an established idea.

In these times where people are all too aware of their personal data and how they are used by Google and Facebook, these and the other FAMGA companies are often seen as having a dangerous monopoly. But consumers cannot run away from their own responsibility as users of Facebook and similar services: That a part of the price we pay for such services is our personal data.
If you are not happy with this, then you do not need to use them, and they will learn to sell their services by some other means.
Ask yourself: Why is it that you do not pay to use Facebook? But there are still plenty of ways you can keep in touch with people. You could write a reminder in your calendar to call your friends at regular intervals. You could hand out flyers on political topics that are close to your own heart, and so on. These solutions are not as effective, just like previous incarnations of social media, like MySpace. Effectiveness, is the benefit we get with competitive monopolies. Read More: Facebook is not about stimulating Democracy.
Of course, companies who hold a monopoly will defend it by non-competitive means, such as lobbying. Businesses strive to eliminate their competitors, so we cannot blame them for trying to achieve a monopoly or influence politicians by lobbying.
On the contrary, our political system should ensure that this is not an attractive option. In the spirit of the famous political economist, Adam Smith, the task of economic theory is to defend capitalism, not individual capitalists. It could be directly, by receiving state aid, or indirectly, via laws that favour one enterprise over another for example, by prohibiting competing technological solutions. Both of these are about raising the price of competing with the monopoly holder—so-called, entry barriers.
So, even though Facebook are tearing their hair out over the new EU data protection regulations GDPR , they also benefit as it is now significantly more costly to compete with them by creating an alternative product. It is almost ironic that a nervousness about competitive monopolies, has in effect, secured the monopoly against competition.
