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 ...
Static Monopoly Price: Deadweight Loss. Monopoly pricing without perfect price discrimination results in market inefficiencies when compared to other market structures. The inefficiencies in question are a loss of both consumer and producer surplus otherwise known as a deadweight loss. The loss in both surplus' are deemed allocatively ...
Given the presence of this deadweight loss, the combined surplus (or wealth) for the monopolist and consumers is necessarily less than the total surplus obtained by consumers by perfect competition. Where efficiency is defined by the total gains from trade, the monopoly setting is less efficient than perfect competition.
Monopolistic competition is a type of imperfect competition such that there are many producers competing against each other but selling products that are differentiated from one another (e.g., branding, quality) and hence not perfect substitutes. In monopolistic competition, a company takes the prices charged by its rivals as given and ignores ...
Bertrand competition is a model of competition used in economics, named after Joseph Louis François Bertrand (1822–1900). It describes interactions among firms (sellers) that set prices and their customers (buyers) that choose quantities at the prices set.
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:
An example of which was seen in 2007, when British Airways was found to have colluded with Virgin Atlantic between 2004 and 2006, increasing their surcharges per ticket from £5 to £60. [8] Regulators are able to assess the level of market power and dominance a firm has and measure competition through the use of several tools and indicators.
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 ...
