Equilibrium in perfect competition is the point where market demands will be equal to market supply. A firm's price will be determined at this point. In the short run, equilibrium will be affected by demand. In the long run, both demand and supply of a product will affect the equilibrium in perfect competition.
The market should adjust to clear any profits if there is perfect competition. In situations where there are non-zero profits, we should expect to see either some form of long run disequilibrium or non-competitive conditions, such as barriers to entry, where there is not perfect competition between firms.

In long-run equilibrium of an industry in which perfect competition prevails, the LRMC = LRAC at the minimum LRAC and associated output. The shape of the long-run marginal and average costs curves is influenced by the type of returns to scale. The long-run is a planning and implementation stage.
This is the case for the long-run equilibrium of perfect competition. Productive efficiency occurs when units of goods are being supplied at the lowest possible average total cost. When drawing diagrams for businesses, this condition is satisfied if the equilibrium is at the minimum point of the average total cost curve. This is again the case ...
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 ...
In the long run a firm operates where marginal revenue equals long-run marginal costs, but only if it decides to remain in the industry. [30] Thus a perfectly competitive firm's long-run supply curve is the long-run marginal cost curve above the minimum point of the long-run average cost curve. [31]
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 ...
The graph below depicts the kinked demand curve hypothesis which was proposed by Paul Sweezy who was an American economist. [29] It is important to note that this graph is a simplistic example of a kinked demand curve. Kinked Demand Curve. Oligopolistic firms are believed to operate within the confines of the kinked demand function.
