Macroeconomics monopolistic and oligopolistic markets

Even when there is a large rise in marginal cost, price tends to stick close to its original, given the high price elasticity of demand for any price rise.

Oligopolies are typically characterized by mutual interdependence where various decisions such as output, price, advertising, and so on, depend on the decisions of the other firm s. The demand curve will be kinked, at the current price. Why does a shift in perceived demand cause a shift in marginal revenue?

Figure 5. Another way of interpreting this shift in demand is to notice that, for each quantity sold, a lower price will be charged. While in some industries this is sufficient to still keep a competitive environment, where each is seeking to beat the others, there is a risk that the limited number of players will collude.

A change in perceived demand will change total revenue at every quantity of output and in turn, the change in total revenue will shift marginal revenue at each quantity of output.

Oligopolies in countries with competition laws[ edit ] Oligopolies become "mature" when they realise they can profit maximise through joint profit maximising. In other words, they need to plan, and work out a range of possible options based on how they think rivals might react.

It provides powerful incentives for innovation, as firms seek to earn profits in the short run, while entry assures that firms do not earn economic profits in the long run. Cost-plus pricing is also called rule of thumb pricing.

Despite its many drawbacks, regulation fosters important change. In this case, the Authentic Chinese Pizza company will determine the profit-maximizing quantity to produce by considering its marginal revenues and marginal costs. For example, it may be accepted that a particular firm is the price leader in an industry, and other firms simply follow the lead of this firm. Monopolistic Competition and Efficiency The long-term result of entry and exit in a perfectly competitive market is that all firms end up selling at the price level determined by the lowest point on the average cost curve. Monopolistic Competitors and Entry If one monopolistic competitor earns positive economic profits, other firms will be tempted to enter the market. Product differentiation Product may be homogeneous steel or differentiated automobiles. Co-operation reduces the uncertainty associated with the mutual interdependence of rivals in an oligopolistic market. These laws are in place to protect consumers, to maintain competition within the market, and to prevent companies from price gouging. Profits are total revenues minus total costs, which is the shaded area above the average cost curve. Thus, firm A will reason that it makes sense to expand output if B holds down output and that it also makes sense to expand output if B raises output. It has been suggested that cost-plus pricing is common because a precise calculation of marginal cost and marginal revenue is difficult for many oligopolists. Oligopoly An oligopoly refers to an economic market where there are a small number of players, be they government or corporations, which dominate the industry. Oligopoly Many purchases that individuals make at the retail level are produced in markets that are neither perfectly competitive, monopolies, nor monopolistically competitive. Their goals: Stamp out competition and set prices. On the other hand, oligopoly is driven by private players in the market.
