[edit] Proposed Additions

A distinction needs to be made between interaction models (Cournot, Stackelberg, game theory, etc), and theories for why oligopolies form and persist.

Government intervention should be discussed in regards to the Aerospace, Transportation, Energy, Banking, and Agricultural sectors, where industry concentration is the highest, and government allocation and regulation play a significant role in shaping the marketplace.

Limit pricing achieved through collusion should be discussed in regards to the persistence of oligopolies.

Examples of implicit/explicit collusion should be given. Implicit collusion could include Trade associations, patent pools, FDA approval process, to name a few. Widely reported examples of explicit collusion include Cargill/ADM/et al. and Visa/MC/Diners.

[edit] Credits

I believe the late Paul Sweezy is the originator of the kinked demand curve, and as I recall from my college economics 25 years ago his name was almost synonymous with it at one time. Therefore whether one agrees with his socialism or not (and I personally do not), my sense is that, at the very least, his name deserves some mention here as he is te originator of the theory. If I am wrong, I welcome your comments. --Gunnermanz 12:19, 9 February 2007 (UTC)

[edit] Kinked-Demand Curve Model

This type of model is common for the analysis of ologoply, but it is just one of many possible models (others are hinted at later in the article). I would recommend mentioning that this is one common model of several that can be used to analyze these types of markets, so that the reader does not believe it to be the only model.

[edit] Monopolisitic Competition example?

Monopolistic Competition is listed at the end of the article as an example of oligopoly, which it is not. While game theory may be used to analyze monopolisitically competitive industries, I think that it confuses the distinction between these types of market structures to include it as an example.

[edit] Oligopoly: A form of economy?

"An oligopoly is a form of economy"

I don't agree with this statement, An oligopoly is a form of Market structure, not a form of economy...

I've correct this definition.

I was the one who posted the material I "blanke" I had posted it by accident.--Gary123 02:10, 8 December 2005 (UTC)

Sweezy's oligopoly ? I erased that.

[edit] Spelling or three terms?

"A" market with a ""few sellers"" (oligopoly) and a "few buyers" (oligopsony) 'is' referred to as a bilateral ologopoly.""

Are there two words here, olIgopoly and olOgopoly? Also, the second paragraph sounds a little szchizophrenic: can it be massaged a bit. Some examples would be helpful. MShonle 08:41, 25 Jul 2004 (UTC)

the whole article is very impressing actually

[edit] plurioligopoly? monoligopoly?

Pluriologopoly and monoligopoly are booger terms. Lets see: mono=one=oligos=one=few=firms? Pluri=more=oligos=few=Plurioligopoly=more than one=few firms=? this page with booger terms!!!!

Ah, but what about polypoly? ;) Spamsara 20:01, 8 July 2007 (UTC)

[edit] Inappropriate Statement by 84.92.44.123

I have reverted edits made by 84.92.44.123 to previous versoin statement added --Julien Deveraux 03:46, 14 July 2005 (UTC)

[edit] Historical examples?

The Monopoly article has a section of historical examples. It would be nice to do the same for this article, naming historical, or current examples of market situations that could be seen as oligopolistic. Some examples could include the aircraft industry, the oil industry or beverage brands such as Pepsi and Coca-Cola. What do you think?


[edit] Monopoly

Monopoly isn't an oligopoly model. I've removed that from the article. 128.100.247.59 (talk) 21:26, 12 March 2008 (UTC)

[edit] Oligopoly in US Media Industries

In order to provide more specific examples of oligopoly in the United States, I added a description of oligopolies in US media industries. I included statistics about media ownership in American film, music, book publishing, and television industries. Inbal36 (talk) 20:47, 15 March 2008 (UTC)
