The Ramsey problem, or Ramsey pricing, or Ramsey–Boiteux pricing, is a second-best policy problem concerning what prices a public monopoly should charge for the various products it sells in order to maximize social welfare (the sum of producer and consumer surplus) while earning enough revenue to cover its fixed costs.
[4] A broader conclusion of the model is that antitrust, or competition, policy should be "discretionary". [5] That is, government regulators who are faced with a proposed merger need to examine each proposal on a case-by-case basis. In some instances, the cost savings might make it worth the loss of competition, while in others they will not.
A short-run monopolistic competition equilibrium graph has the same properties of a monopoly equilibrium graph. Long-run equilibrium of the firm under monopolistic competition. The company still produces where marginal cost and marginal revenue are equal; however, the demand curve (MR and AR) has shifted as other companies entered the market ...
The total surplus of perfect competition market is the highest. And the total surplus of imperfect competition market is lower. In the monopoly market, if the monopoly firm can adopt first-level price discrimination, the consumer surplus is zero and the monopoly firm obtains all the benefits in the market. [15]
In economics, a government-granted monopoly (also called a "de jure monopoly" or "regulated monopoly") is a form of coercive monopoly by which a government grants exclusive privilege to a private individual or firm to be the sole provider of a good or service; potential competitors are excluded from the market by law, regulation, or other mechanisms of government enforcement.
For example, in most countries, regulation controls the sale and consumption of alcohol and prescription drugs, as well as the food business, provision of personal or residential care, public transport, construction, film and TV, etc. Monopolies, especially those that are difficult to abolish (natural monopoly), are often regulated.
A competition regulator is the institution that oversees the functioning of markets. It identifies and corrects practices causing market impediments and distortions through competition law (also known as antitrust law). [1]
[1] [2] Competition law is implemented through public and private enforcement. [3] It is also known as antitrust law (or just antitrust [4]), anti-monopoly law, [1] and trade practices law; the act of pushing for antitrust measures or attacking monopolistic companies (known as trusts) is commonly known as trust busting.
