Microeconomics is a branch of economics that studies the behaviour of individuals and firms in making decisions regarding the allocation of scarce resources and the interactions among these individuals and firms.
Monopolistic competition is a type of imperfect competition such that many producers sell products that are differentiated from one another and hence are not perfect substitutes. In monopolistic competition, a firm takes the prices charged by its rivals as given and ignores the impact of its own prices on the prices of other firms. In the presence of coercive government, monopolistic competition will fall into government-granted monopoly. Unlike perfect competition, the firm maintains spare capacity. Models of monopolistic competition are often used to model industries. Textbook examples of industries with market structures similar to monopolistic competition include restaurants, cereal, clothing, shoes, and service industries in large cities. The "founding father" of the theory of monopolistic competition is Edward Hastings Chamberlin, who wrote a pioneering book on the subject, Theory of Monopolistic Competition (1933). Joan Robinson published a book The Economics of Imperfect Competition with a comparable theme of distinguishing perfect from imperfect competition.

Porter's Five Forces Framework is a tool for analyzing competition of a business. It draws from industrial organization (IO) economics to derive five forces that determine the competitive intensity and, therefore, the attractiveness of an industry in terms of its profitability. An "unattractive" industry is one in which the effect of these five forces reduces overall profitability. The most unattractive industry would be one approaching "pure competition", in which available profits for all firms are driven to normal profit levels. The five-forces perspective is associated with its originator, Michael E. Porter of Harvard University. This framework was first published in Harvard Business Review in 1979.
In public choice theory and in economics, rent-seeking involves seeking to increase one's share of existing wealth without creating new wealth. Rent-seeking results in reduced economic efficiency through poor allocation of resources, reduced actual wealth-creation, lost government revenue, increased income inequality, and (potentially) national decline.
In theories of competition in economics, a barrier to entry, or an economic barrier to entry, is a fixed cost that must be incurred by a new entrant, regardless of production or sales activities, into a market that incumbents do not have or have not had to incur.
In economics and business ethics, a coercive monopoly is a firm that is able to raise prices, and make production decisions, without risk of competition arising to draw away their customers. A coercive monopoly is not merely a sole supplier of a particular kind of good or service, but it is a monopoly where there is no opportunity to compete with it through means such as price competition, technological or product innovation, or marketing; entry into the field is closed. As a coercive monopoly is securely shielded from possibility of competition, it is able to make pricing and production decisions with the assurance that no competition will arise. It is a case of a non-contestable market. A coercive monopoly has very few incentives to keep prices low and may deliberately price gouge consumers by curtailing production. Also, according to economist Murray Rothbard, "a coercive monopolist will tend to perform his service badly and inefficiently."
In economics a monopoly is a firm that lacks any viable competition, and is the sole producer of the industry's product. In a normal competitive situation, no firm can charge a price that is significantly higher than the Marginal (Economic) cost of producing the product. If any firm doing business within a competitive situation tries to raise prices significantly higher than the Marginal cost of producing the product, it will lose all of its customers to either other existing firms that charge lower prices, or to a new firm that will find it profitable to use a lower price to take customers away from the firm charging the higher price. But since the monopoly firm does not have to worry about losing customers to competitors, it can set a Monopoly price that is significantly higher than its marginal cost, allowing it to have an economic profit that is significantly higher than the normal profit that is typically found in a perfectly competitive industry. The high economic profit obtained by a monopoly firm is referred to as monopoly profit.
In economics and commerce, the Bertrand paradox — named after its creator, Joseph Bertrand — describes a situation in which two players (firms) reach a state of Nash equilibrium where both firms charge a price equal to marginal cost ("MC"). The paradox is that in models such as Cournot competition, an increase in the number of firms is associated with a convergence of prices to marginal costs. In these alternative models of oligopoly, a small number of firms earn positive profits by charging prices above cost. Suppose two firms, A and B, sell a homogeneous commodity, each with the same cost of production and distribution, so that customers choose the product solely on the basis of price. It follows that demand is infinitely price-elastic. Neither A nor B will set a higher price than the other because doing so would yield the entire market to their rival. If they set the same price, the companies will share both the market and profits.
An economic system is a system of production, resource allocation and distribution of goods and services within a society or a given geographic area. It includes the combination of the various institutions, agencies, entities, decision-making processes and patterns of consumption that comprise the economic structure of a given community. As such, an economic system is a type of social system. The mode of production is a related concept. All economic systems have three basic questions to ask: what to produce, how to produce and in what quantities and who receives the output of production.
In business, the difference between the sale price and the production cost of a product is the unit profit. In economics, the sum of the unit profit, the unit depreciation cost, and the unit labor cost is the unit value added. Summing value added per unit over all units sold is total value added. Total value added is equivalent to revenue less intermediate consumption. Value added is a higher portion of revenue for integrated companies, e.g., manufacturing companies, and a lower portion of revenue for less integrated companies, e.g., retail companies. Total value added is very closely approximated by compensation of employees plus earnings before taxes. The first component is a return to labor and the second component is a return to capital. In national accounts used in macroeconomics, it refers to the contribution of the factors of production, i.e., capital and labor, to raising the value of a product and corresponds to the incomes received by the owners of these factors. The national value added is shared between capital and labor, and this sharing gives rise to issues of distribution.
In economics, the theory of contestable markets, associated primarily with its 1982 proponent William J. Baumol, holds that there are markets served by a small number of firms that are nevertheless characterized by competitive equilibria because of the existence of potential short-term entrants.
In economics and particularly in industrial organization, market power is the ability of a firm to profitably raise the market price of a good or service over marginal cost. In perfectly competitive markets, market participants have no market power. A firm with total market power can raise prices without losing any customers to competitors. Market participants that have market power are therefore sometimes referred to as "price makers" or "price setters", while those without are sometimes called "price takers". Significant market power occurs when prices exceed marginal cost and long run average cost, so the firm makes economic profit.
In economics, profit in the accounting sense of the excess of revenue over cost is the sum of two components: normal profit and economic profit. Normal profit is the profit that is necessary to just cover the opportunity costs of the owner-manager or of the firm's investors. In the absence of this profit, these parties would withdraw their time and funds from the firm and use them to better advantage elsewhere. In contrast, economic profit, sometimes called excess profit, is profit in excess of what is required to cover the opportunity costs.
In economics, gains from trade are the net benefits to economic agents from being allowed an increase in voluntary trading with each other. In technical terms, they are the increase of consumer surplus plus producer surplus from lower tariffs or otherwise liberalizing trade.
A distortion is "any departure from the ideal of perfect competition that therefore interferes with economic agents maximizing social welfare when they maximize their own". A proportional wage-income tax, for instance, is distortionary, whereas a lump-sum tax is not. In a competitive equilibrium, a proportional wage income tax discourages work.
The following outline is provided as an overview of and topical guide to economics:
A monopoly price is set by a monopoly. A monopoly occurs when a firm is the only firm in an industry producing the product, such that the monopoly faces no competition. A monopoly has absolute market power, and thereby can set a monopoly price that will be above the firm's marginal (economic) cost, which is the change in total (economic) cost due to one additional unit produced.
