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. The company still produces where marginal cost and marginal revenue are equal; however, the demand curve (MR and AR) has shifted as other companies entered the market ...
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.
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.
This is termed "monopolistic competition", whereas in an oligopoly, the companies interact strategically. In general, the main results from this theory compare the price-fixing methods across market structures, analyze the effect of a certain structure on welfare, and vary technological or demand assumptions in order to assess the consequences ...
When this happens, firms will not have incentive to enter the market making zero profit the equilibrium point in this market. This can also be illustrated in the opposite way. Let us consider a case where there are too many firms in the market, causing a negative profit. A negative profit would mean that firms would start to leave the market.
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.
There are four main forms of market structures that are observed: perfect competition, monopolistic competition, oligopoly, and monopoly. [11] Perfect competition and monopoly represent the two extremes of market structure, respectively. Monopolistic competition and oligopoly exist in between these two extremes. [10]
Within monopolistic competition market structures all firms have the same, relatively low degree of market power; they are all price makers, rather than price takers. In the long run, demand is highly elastic, meaning that it is sensitive to price changes. In order to raise their prices, firms must be able to differentiate their products from ...
