In economics, specifically general equilibrium theory, a perfect market, also known as an atomistic market, is defined by several idealizing conditions, collectively called perfect competition, or atomistic competition.
The correct sequence of the market structure from most to least competitive is perfect competition, imperfect competition, oligopoly, and pure monopoly. The main criteria by which one can distinguish between different market structures are: the number and size of firms and consumers in the market, the type of goods and services being traded ...
While competition is understood at a macro-scale, as a measure of a country's advantage or disadvantage in selling its products in international markets. Trade competition can be defined as the ability of a firm, industry, city, state or country, to export more in value added terms than it imports.
"Perfect Competition" refers to a market structure that is devoid of any barriers or interference and describes those marketplaces where neither corporations nor consumers are powerful enough to affect pricing. In terms of economics, it is one of the many conventional market forms and the optimal condition of market competition. [12]
There are two fundamental theorems of welfare economics. The first states that in economic equilibrium , a set of complete markets , with complete information , and in perfect competition , will be Pareto optimal (in the sense that no further exchange would make one person better off without making another worse off).
A graphical representation of Porter's five forces. Porter's Five Forces Framework is a method of analysing the competitive environment of a business. It draws from industrial organization (IO) economics to derive five forces that determine the competitive intensity and, therefore, the attractiveness (or lack thereof) of an industry in terms of its profitability.
He later motivated his use of mathematics with the analogy that the pure theory of economics is “a physico-mathematical science like mechanics” [8] and argued that the way economics proceeds is rigorously identical to the one of rational and celestial mechanics. [9] [10] [11]
Since both A and B know this, they will each try to undercut their competitor until the product is selling at zero economic profit. This is the pure-strategy Nash equilibrium. Recent work has shown that there may be an additional mixed-strategy Nash equilibrium with positive economic profits under the assumption that monopoly profits are infinite.
