In either model, the strategic problem for each firm is to choose a product quality and a price to maximize its profits, recognizing that the other firm is doing the same. Our major results are as follows. First, in both the simultaneous-product-choice model and the sequential-product-choice model, the . Stackelberg Model of Duopoly Stackelberg’s Model of Duopoly also has to do with companies trying to decide how much of a homogeneous good to produce. The principal diﬁerence between the Cournot model and the Stack-elberg model is that instead of moving simultaneously (as in the Cournot model) the ﬂrms now move Size: KB.

In contrast, our model is in the spirit of Kreps and Scheinkman (): the incumbent and entrant sequentially precommit to capacity levels before competing in price. Conclusion. Barriers to entry generally operate on the principle of asymmetry, where different firms have different strategies, assets, capabilities, access, etc.
Barriers become dysfunctional when they are so high that incumbents can keep out virtually all competitors, giving rise to monopoly or oligopoly. For entrants, the basic entry technological constraint is the minimum quality standard.
In differentiated products markets, when there is no minimum quality standard and the entry cost is small, the entrant’ profit is the same, whether they choose the high quality or low quality to enter the product market. A model of duopoly suggesting a theory of entry barriers, Dixit, A.
The Bell Journal of Economics, This research examines a model of duopoly with fixed costs. The objective is to show that the presence of an established firm in a model, might create barriers for the entry of new firms.

An extension of the model. Long-run Profit: Oligopolies often earn an economic profit in the long run due to high barriers to entry which prevent new firms from entering the market.
Efficiency: No, Oligopolies price above marginal cost and do not produce at the lowest average cost so they are not allocatively or productively efficient.
Graph: While there is a graph for oligopolies these firm’s behavior is better. We revisit the classic discussion comparing price and quantity competition, but in a mixed oligopoly in which one state-owned public firm competes against private firms.
It has been shown that in a mixed duopoly, price competition yields a larger profit for the private firm. This implies that firms face weaker competition under price competition, which contrasts sharply with the case of a Cited by: ADVERTISEMENTS: The uncertainty is respect of behaviour pattern of a firm under oligopoly arising our of their unpredictable action and reaction makes a systematic analysis of oligopoly difficult.
However, classical and modern economists have developed a variety of models based on different behavior assumptions. These models can broadly be classified into two categories (I) classical [ ]. Duopoly analysis by economists dates back to the 19th century.
Some of the central concepts of duopoly analysis have to do with strategic behavior, and the analysis of strategic behavior is the heart of the 20th century discipline calledgame theory.
So game theory builds on duopoly theory. We will turn to game theory in the next Size: KB. Summing Up Barriers to Entry. Table 1 lists the barriers to entry that have been discussed here.
This list is not exhaustive, since firms have proved to be highly creative in inventing business practices that discourage competition. When barriers to entry exist, perfect competition is no longer a reasonable description of how an industry works. A Duopoly is a business term to describe an industry which has just two producers in one market.
It is a similar concept to a monopoly, except a monopoly has only one producer for its one market. Because of its simplicity, the duopoly model is the most studied model of oligopoly.

Duopoly is ideally suited for collusion analysis. It contains the minimum number of firms needed for an oligopoly and provides all of the insight that would be generated from analyzing three or more firms.
Another model using the duopoly market structure is game theory, which investigates the interdependent actions of two competing firms. Game. REAL WORLD EXAMPLES OF DUOPOLY: 6. GAME THEORY A tool to analyze strategic interaction.

For which of the following market structures is it assumed that there are barriers to entry. In the long run, the price of the good will equal the minimum of the average cost.

Some of the earliest applications of game theory is the analyses of imperfect competition by Cournot () and Bertrand (), a century before Nash (). This chapter applies the solution concepts of rationalizability and Nash equilibrium to those models of imperfect competition. Cournot (Quantity) Competition.

The chapter clarifies the way oligopoly theory has, and has not, progressed in the years since Cournot developed his theory. Although oligopoly fits conceptually between the extremes of monopoly and perfect competition, its study requires a rather different set of tools—that is, those of game theory.
The hallmark of oligopoly is the Cited by: In the contestable market model, an oligopoly with no barriers to entry sets a: A. monopoly price. price that significantly exceeds average total cost. price that is equal to average total cost. collusive price. If no barriers to entry exist, an oligopolistic firm will charge a price that is very close to the competitive price in order to discourage entry.
