A perfect competitive market is when no buyer or seller has market power. I apologize but I an unable to locate an example. AnswerParty
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," while those without are sometimes called "price takers." Significant market power is when prices exceed marginal cost and long run average cost, so the firm makes economic profits.
A firm with market power has the ability to individually affect either the total quantity or the prevailing price in the market. Price makers face a downward-sloping demand curve, such that price increases lead to a lower quantity demanded. The decrease in supply as a result of the exercise of market power creates an economic deadweight loss which is often viewed as socially undesirable. As a result, many countries have anti-trust or other legislation intended to limit the ability of firms to accrue market power. Such legislation often regulates mergers and sometimes introduces a judicial power to compel divestiture.
Industrial organization is the field of economics that builds on the theory of the firm in examining the structure of, and boundaries between, firms and markets. Industrial organization adds to the perfectly competitive model such real-world complications as transaction costs, limited information, and barriers to entry of new firms that may be associated with imperfect competition. It analyzes determinants of firm and market organization and behavior as between competition and monopoly, including from government actions.
There are different approaches to the subject. One is descriptive in providing an overview of industrial organization, such as measures of competition and the size-concentration of firms in an industry. A second uses microeconomic models to explain internal firm organization and market strategy. A third aspect is oriented to public policy as to economic regulation, antitrust law, and, more generally, the economic governance of law in defining property rights, enforcing contracts, and providing organizational infrastructure.
In economic theory, perfect competition (sometimes called pure competition) describes markets such that no participants are large enough to have the market power to set the price of a homogeneous product. Because the conditions for perfect competition are strict, there are few if any perfectly competitive markets. Still, buyers and sellers in some auction-type markets, say for commodities or some financial assets, may approximate the concept. As a Pareto efficient allocation of economic resources, perfect competition serves as a natural benchmark against which to contrast other market structures.
In economic theory, imperfect competition is a type of market structure showing some but not all features of competitive markets.
Forms of imperfect competition include:
In economics, market structure is the number of firms producing identical products which are homogeneous. The types of market structures include the following:
The imperfectly competitive structure is quite identical to the realistic market conditions where some monopolistic competitors, monopolists, oligopolists, and duopolists exist and dominate the market conditions. The elements of Market Structure include the number and size distribution of firms, entry conditions, and the extent of differentiation.
