Question

Monopoly
Oligopoly
Monopolistic competition
Perfect competition

Answer 1

Monopoly - is an extreme in economy; the product offers only 1 producer.
F.e.:gas-works (in Slovakia)
Oligopoly - situation, when in a certain branch of economy exist only a few of big companies and a lot of buyers.
Monopolistic competition - is a market of 1 brand of goods, that is produced by many producers.
Perfect competition - don´t exists in real economy. Is based on premises:
- all producers produce same product
- all producers have chance enter absolute free.

Answer 2

Most of these words come from Greek. Monopoly* is a situation in which a single company - business owns a big position in production or a service and there is no other choice for people if they want to have the product or the service, than this company. That means that the prices can go extremely high. Oligopoly is a similar situation, only here there is more that one company, but still not enough to drop the prices. Monopolistic competition is a competition (most likely in business, production and social services) where there are no other powerful competitors, nor a chance to be, (similar enough to monopoly). A perfect competition in economical terms is succeeded when a lot of companies (of the same economical strength) offer the same products or services at the same time. This is very convenient because prices go down and there are a lot of choices.
*Monopoly is also a table game with money, investments, etc

Answer 3

I'll do one of them- monopoly means one company has the whole market share - there is no competition. This is illegal in the US because without competition, that is if there is only one place to buy a certain thing, one company, then they can raise prices and charge whatever they want. The phone company was busted up into smaller companies a while back for this reason.

Answer 4

Monopoly = there's only ONE institution who sell some stuff, no competitor.

Oligopoly >< Monopoly.

Monopolistic Competition = I think there will be no competition in monopolistic things

Perfect competition = there are many buyer and many seller, so
only the power of bargaining in the market can decide the level of price, this is perfect competition

1: monopoly In economics, a monopoly is defined as a persistent market situation where there is only one provider of a product or service. Monopolies are characterized by a lack of economic competition for the good or service that they provide and a lack of viable substitute goods.
example: say for instance everyone needs gas for their car (persistant market product) but there is only one gas company that will sell you that gas you have no choice for price or product (monoply)

2: Oligopoly: Literally, few sellers; a market situation in which a few individuals or business organizations own or control the total supply of a given commodity or service
example: 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. A price decrease, for example, will normally prove unprofitable for the price-cutter. The others will promptly match his lower price, thus removing any incentive for buyers to switch suppliers. With his market share unchanged, but price now at a lower level, the price-cutter's profits are presumably lower than before. Similarly, a failure to go along with a price increase will generally prove unprofitable, since the others will quickly drop back to protect their market share if there's a holdout still selling at the lower price, the result being that the holdout gets no increase in his market share and foregoes a higher per-unit price that all could have had if he had gone along with the change. By a series of such adjustments, rational oligopolists are expected to eventually arrive at the price level that will maximize their joint profits

3:Monopolistic competition: Monopolistic competition is a market structure characterized by a large number of relatively small firms. While the goods produced by the firms in the industry are similar, slight differences often exist. As such, firms operating in monopolistic competition are extremely competitive but each has a small degree of market control.
Example: the hairdressing industry. There are many hairdressers in the country, and most hairdressing firms are quite small. There is free entry and it is at least possible that people know enough about their hairdressing options so that the "sufficient knowledge" condition is fulfilled. But the products of different hairdressers are not perfect substitutes. At the very least, their services are differentiated by location. A hairdresser in Center City Philadelphia is not a perfect substitute for a hairdresser in the suburbs -- although they may be good substitutes from the point of view of a customer who lives in the suburbs but works in Center City. Hairdressers' services may be differentiated in other ways as well. Their styles may be different; the decor of the salon may be different, and that may make a difference for some customers; and even the quality of the conversation may make a difference.

4: Perfect competition: Perfect competition is a theoretical market structure. It is primarily used as a benchmark against which other market structures are compared. The industry that best reflects perfect competition in real life is the agricultural industry. A market structure in which the following five criteria are met:
1. All firms sell an identical product.
2. All firms are price-takers.
3. All firms have a relatively small market share.
4. Buyers know the nature of the product being sold and the prices
charged by each firm.
5. The industry is characterized by freedom of entry and exit.
example, in a perfectly competitive market, should a single firm decide to increase its selling price of a good, the consumers can just turn to the nearest competitor for a better price, causing any firm that increases its prices to lose market share and profits.
