No. Depending on how you count them, there are at least a half-dozen to a dozen manufacturers of digital cameras (Canon, Nikon, Olympus, Sony, Samsung, Panasonic, Pentax, maybe HP, Casio, Leica, Ricoh, Fuji). Include mobile phone makers like Apple that have taken a big chunk of from the point-and-shoot makers (RIP Kodak, Minolta, Yashica, Konika) and there are too many players for an oligopoly. The number hasn't changed that much in the past 20-30 years.

Increased Oil Production.

No

Supernormal profits due to high barriers to entry. Profits in the long run are determined by the barriers to entry. If there is high barriers to entry, new firms cannot enter the industry easily and hence cannot competed with existing firms for profits. Existing firms would be able to enjoy supernormal profits. On the contrary, weak barriers to entry means that the long run profits would be competed away by new firms entering the industry, hence firms would earn normal profits. Oligopoly market is characterised by high barriers to entry, largely due to non-price competition such as branding, advertising, etc. High barriers could also be due to economies of scale and high fixed cost.

No and Yes. All professional sports, with the exception of baseball, are required to abide by all applicable anti-trust laws. Baseball (based on the 1972 US Supreme Court decision - please see http://caselaw.lp.findlaw.com/scripts/getcase.pl?court=us&vol=407&invol=258 for the full case) confirms a prior ruling that baseball is more of a game than a business and therefore anti-trust laws do not apply. Hope that helps!

Oligopolistic

Type your answer here... yes

The oligopoly is an industry that is controlled by a limited number of sellers. It has regulations that help keep a balance of from one group of oligopolist to another since there is so few of these groups. It also keeps anyone group from strong arming a vendor or another group.

OPEC would never trade with the country that rose the price of petroleum.

the four largest firms produce at least 70 to 80 % of the output

No - it has lots of competitors.

Explain how price and output decision are taken under conditions of oligopoly.

The largest oil producing country is arabia.all the south west countries are famous for this purpose.But the iran,iraq,oman are also very famous.the most largest one is soud-i-arabia.here about 250 meter well of oil is present.from this well the pipe line system has made between the amrica and other europien countries.

Online auctioning is an example of Pure Competition.

Here are some examples of the others:

An oligopoly is market form in which a market is dominated by a small number of sellers (oligopolists). The word is derived from the Greek for few sellers. Because there are few participants in this type of market, each oligopolist is aware of the actions of the others. Oligopolistic markets are characterised by interactivity. The decisions of one firm influence, and are influenced by, the decisions of other firms. Strategic planning by oligopolists always involves taking into account the likely responses of the other market participants. An oligopy is a form of economy. As a quantitative description of oligopoly, the four-firm concentration ratio is often utilized. This measure expresses the market share of the four largest firms in an industry as a percentage. Using this measure, an oligopoly is defined as a market in which the four-firm concentration ratio is above 40%. An example would be Indian mobile industry , with a four-firm concentration ratio of over 70% and the cold drink industry also in the U.S.A has a two firm concentration ratio of a staggering 85%.

In an oligopoly, firms operate under imperfect competition, the demand curve is kinked to reflect inelasticity below market price and elasticity above market price, the product or service firms offer are differentiated and barriers to entry are strong. Following from the fierce price competitiveness created by this sticky-upward demand curve, firms utilize non-price competition in order to accrue greater revenue and market share.

In industrialized countries oligopolies are found in many sectors of the economy, such as cars, consumer goods, and steel production. Unprecedented levels of competition, fueled by increasing globalisation, have resulted in the emergence of oligopsony in many market sectors, such as the aerospace industry. There are now only a small number of manufacturers of civil passenger aircraft. A further instance arises in a heavily regulated market such as wireless communications. Typically the state will license only two or three providers of cellular phone services.

Oligopolistic competition can give rise to a wide range of different outcomes. In some situations, the firms may collude to raise prices and restrict production in the same way as a monopoly. Where there is a formal agreement for such collusion, this is known as a cartel. Firms often collude in an attempt to stabilise unstable markets, so as to reduce the risks inherent in these markets for investment and product development. There are legal restrictions on such collusion in most countries. There does not have to be a formal agreement for collusion to take place (although for the act to be illegal there must be a real communication between companies) - for example, in some industries, there may be an acknowledged market leader which informally sets prices to which other producers respond, known as price leadership.
