The difference between the company's average revenue and average cost, multiplied by the quantity sold (Qs), gives the total profit. 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.
Dixit–Stiglitz model is a model of monopolistic competition developed by Avinash Dixit and Joseph Stiglitz (1977). [1] It has been used in many fields of economics including macroeconomics, economic geography and international trade theory. The model formalises consumers' preferences for product variety by using a CES function.
Monopolistic competition, a type of imperfect competition where there are many sellers, selling products that are closely related but differentiated from one another (e.g. quality of products may differentiate) and hence they are not perfect substitutes. This market structure exists when there are multiple sellers who attempt to seem different ...

The transition from the short-run to the long-run may be done by considering some short-run equilibrium that is also a long-run equilibrium as to supply and demand, then comparing that state against a new short-run and long-run equilibrium state from a change that disturbs equilibrium, say in the sales-tax rate, tracing out the short-run ...
In addition, monopoly price will prevent new business from entering the market and restrict innovation. A monopoly would not like to invest more on research and development or innovation due to it already has a captive market. Then the lack of innovation may block market competition and limit the industry’s growth potential in long run.
Without barriers to entry and collusion in a market, the existence of a monopoly and monopoly profit cannot persist in the long run. [1] [3] Normally, when economic profit exists within an industry, economic agents form new firms in the industry to obtain at least a portion of the existing economic profit.
In the long run, a firm will theoretically have zero expected profits under the competitive equilibrium. 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 ...
