In economics, deadweight loss is the loss of societal economic welfare due to production/consumption of a good at a quantity where marginal benefit (to society) does not equal marginal cost (to society) – in other words, there are either goods being produced despite the cost of doing so being larger than the benefit, or additional goods are not being produced despite the fact that the ...
The clearest example is a monopoly, where a single producer has complete control over supply and can extract a monopoly price. An oligopoly - a small number of producers - can also sustain an undersupply if no producers attempt to gain market share with lower prices at higher volume. Lack of supply competition can arise in many different ways:
Deadweight loss is considered detrimental to society and market participation. As such, monopolists have substantial economic interest in improving their market information and market segmenting. [43] There is important information for one to remember when considering the monopoly model diagram (and its associated conclusions) displayed here.
[1] [2] A monopoly occurs when a firm lacks any viable competition and is the sole producer of the industry's product. [1] [2] Because a monopoly faces no competition, it has absolute market power and can set a price above the firm's marginal cost. [1] [2] The monopoly ensures a monopoly price exists when it establishes the quantity of the ...
On a standard supply and demand diagram, consumer surplus is the area (triangular if the supply and demand curves are linear) above the equilibrium price of the good and below the demand curve. This reflects the fact that consumers would have been willing to buy a single unit of the good at a price higher than the equilibrium price, a second ...
This is a net social loss and is called deadweight loss. It is a measure of the market failure caused by monopsony power, through a wasteful misallocation of resources. As the diagram suggests, the size of both effects increases with the difference between the marginal revenue product MRP and the market wage determined on the supply curve S ...
[3] [4] At this point the social surplus is maximized with no deadweight loss (the latter being the value society puts on that level of output produced minus the value of resources used to achieve that level). Allocative efficiency is the main tool of welfare analysis to measure the impact of markets and public policy upon society and subgroups ...
In a monopoly, marginal revenue (MR) equals marginal cost (MC). The equilibrium quantity is obtained from where MR and MC intersect and the equilibrium price can be found on the demand curve where MR = MC. Property P1 is not satisfied because the amount demand and the amount supplied at the equilibrium price are not equal.
