Razlika je u tome da li neko ima monopol ili nema.
Nisam bas siguran u to -
In economics, a monopoly (from the Greek monos, one + polein, to sell) is defined as a persistent market situation where there is only one provider of a kind of 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.
Microsoft nikako ne moze da upadne u ovu definiciju, posto:
a) konkurencija nesumnjivo postoji
b) svaki korisnik moze da kupi proizvod konkurencije ako to zeli
c) odredjena konkurencija MS-u je cak i besplatna (Linux) -
Dakle, jedina definicija u koju Microsoft moze da upadne je:
Industries which are dominated by a single firm may allow the firm to act as a near-monopoly or "de facto monopoly", a practice known in economics as monopolistic competition. Common historical examples arguably include corporations such as Microsoft and Standard Oil (Standard's market share of refining was 64% in competition with over 100 other refiners at the time of the trial that resulted in the government-forced breakup). Practices which these entities may be accused of include dumping products below cost to harm competitors, creating tying arrangements between their products, and other practices regulated under antitrust law.
Monopolistically competitive markets have the following characteristics:
* There are many producers and many consumers in a given market.
* Consumers have clearly defined preferences and sellers attempt to differentiate their products from those of their competitors; the goods and services are heterogeneous.
* There are no barriers to entry and exit[1].
The characteristics of a monopolistically competitive market are exactly the same as in perfect competition, with the exception of the heterogeneous products. This gives the company a certain amount of influence over the market; it can raise its prices without losing all the customers, owing to brand loyalty. This means its demand curve is downwards sloping, in contrast to perfect competition.
