In oligopoly a change in marginal cost never has an affect on output or price d none of the statements associated with this question are true difficulty: medium 3 in a sweezy oligopoly, a decrease in a firm's marginal cost generally leads to: difficulty: easy 9-1. Oligopoly price and output under oligopoly - oligopoly is best defined by the market conduct (behaviour) of firms a market dominated by a few large firms ie a market dominated by a few large firms ie. The kinked-demand curve theory is an economic theory regarding oligopoly and monopolistic competitionkinked demand was an initial attempt to explain sticky prices. Cournot competition is an economic model used to describe an industry structure in which companies compete on the amount of output they will produce, which they decide on independently of each other and at the same time. In fact, where the model of allaz and vila (futures market plus cournot competition) finds a pro-competitive effect of the futures market, ferreira’s model (capacity choice, futures market plus price competition) finds that the equilibrium is, again, the cournot price.

In the cournot model, firms choose the quantities to produce and prices adjusted along to clear the market in bertrand model, firms set different prices for the same product so the firm that has the lowest price can sell to the whole market. Kinked demand curve model (sweezy model) in many oligopolistic industries, prices remain sticky or inflexible for a long time even though the economic conditions change many explanations have been given for this price rigidity under oligopoly and the most popular explanation is the kinked demand curve hypothesis given by an american economist paul sweezy. The kinked demand curve of oligopoly was developed by paul m sweezy in 1939 instead of laying emphasis on price-output determination, the model explains the behavior of oligopolistic organizations the model advocates that the behavior of oligopolistic organizations remain stable when the price and output are determined.

However, in the same year (1939), p sweezy published an article in which he introduced the kinked-demand curve as an operational tool for the determination of the equilibrium in oligopolistic markets his model, which still holds (surprisingly) an important position as an ‘oligopoly theory’ in most textbooks, may be presented as follows. Cournot’s model of oligopoly • single good produced by n ﬁrms • cost to ﬁrm i of producing qi units: ci(qi), where ci is nonnegative and increasing • if ﬁrms’ total output is q then market price is p(q). The kinked demand curve (sweezy, 1939 hall and hitch, 1939) has been one of the staples of oligopoly theory it was originally formulated as a theory of resents one of the –rst attempts at a dynamic model of oligopoly however, this modelling has been criticized implicit in the analysis is the assumption that. The kinked‐demand theory of oligopoly illustrates the high degree of interdependence that exists among the firms that make up an oligopoly the market demand curve that each oligopolist faces is determined by the output and price decisions of the other firms in the oligopoly this is the major contribution of the kinked‐demand theory. Oligopoly and kinked demand curve paul m sweezy in 1939 suggested that the ordinary concept of a demand curve is inapplicable to oligopoly the assumption that everything else would remain unchanged if an oligopoly changed their price was unrealistic.

Econometrica, vol 56, no 3 (may, 1988), 571-599 a theory of dynamic oligopoly, ii: price competition, kinked demand curves, and edgeworth cycles by eric maskin and jean tirole1 we provide game theoretic foundations for the classic kinked demand curve equilibrium. Cournot model of oligopoly is perchance the prime model which explains the mannerism of a single industry under stipulations of monopoly and perfect competition an illustration would explain the oligopolistic situation in the market. Sweezy’s kinked demand curve model of oligopoly assumptions: 1 if a firm raises prices, other firms won’t follow and the firm loses a lot of business. Sweezy and cartel oligopoly 1 exercise 24 sweezy and cartel oligopoly the sweezy model, or the kinked demand model, shows that price stability can exist without collusion in an oligopoly.

Article summary: the article attempts to explain oligopoly in us marketsit explain under which model of oligopoly airlines operate under ie sweezy model, cournot model, stackelberg model or bertrand modelif they do not operate under any of these, what is the reason for the same. There are various oligopoly models like cournot oligopoly, sweezy oligopoly, stackelberg oligopoly, bertrand oligopoly, etc each oligopoly model has a different set of characteristics because of specific behaviors of their firms in the industry. The sweezy model of oligopoly reveals that a capacity constraints are not important in determining market performance b perfectly competitive prices can arise in markets with only a few firms c changes in marginal cost may not affect prices. § key feature of sweezy model sweezy oligopoly summary § firms believe rivals match price cuts, but not price increases § firms operating in a sweezy oligopoly maximize profit by producing where mr s = mc. The model explains why oligopoly prices are stable but it fails to explain how the industry-wide price was established in the first place this point requires a little elucidation.

The kinked demand curve model was developed by paul sweezy (1939) according to him, the firms under oligopoly try to avoid any activity which could lead to price wars among them according to him, the firms under oligopoly try to avoid any activity which could lead to price wars among them.

- A model of oligopoly was first of all put forward by cournota french economist, in 1838 cournot’s model of oligopoly is one of the oldest theories of the behaviour of the individual firm and relates to non-collusive oligopoly.
- Oligopoly, monopolistic competition, cartels and collusion, market structure measurement, census measures, cournot model, stackelberg model, concentration ratios, sweezy model, oligopoly theory are the important key points of lecture slides of managerial economics.

Analyse the cournot model and the sweezy model in determining the market equilibrium introduction if seen in terms of competition, market structures can be arranged in the sequence starting from the perfectly competitive market, monopolistic competition market, oligopoly market and finally the monopoly market. Sweezy, paul m 1939 demand under conditions of oligopoly journal of political economy 47:568-573 cournot oligopoly is the simplest model of oligopoly in that firms are assumed to be naive when they think that their actions will not generate any reaction from the rivals in other words, according to the cournot model, rival firms choose.
