  2. Perfect competition - Wikipedia

    en.wikipedia.org/wiki/Perfect_competition

    In a perfectly competitive market, the demand curve facing a firm is perfectly elastic. As mentioned above, the perfect competition model, if interpreted as applying also to short-period or very-short-period behaviour, is approximated only by markets of homogeneous products produced and purchased by very many sellers and buyers, usually ...

  3. Competition (economics) - Wikipedia

    en.wikipedia.org/wiki/Competition_(economics)

    The firms within a perfectly competitive market are small, with no larger firms controlling a significant proportion of market share. [6] These firms sell almost identical products with minimal differences or in-cases perfect substitutes to another firm's product. The idea of perfectly competitive markets draws in other neoclassical theories of ...

  4. Market power - Wikipedia

    en.wikipedia.org/wiki/Market_power

    Firms competing in a perfectly competitive market faces a market price that is equal to their marginal cost, therefore, no economic profits are present. The following criteria need to be satisfied in a perfectly competitive market: Producers sell homogenous goods; All firms are price takers; Perfect information; No barriers to enter and exit

  5. Market structure - Wikipedia

    en.wikipedia.org/wiki/Market_structure

    Example: Agricultural products which have many buyers and sellers, selling homogeneous goods where the price is determined by the demand and supply of the market and not individual firms. In the short run, a firm in a perfectly competitive market may gain profits or loss, but in the long run, due to the entry and exit of new firms, price will ...

  6. Oligopoly - Wikipedia

    en.wikipedia.org/wiki/Oligopoly

    If the firms are colluding in the oligopoly, they can set the price at a high profit-maximising level. Perfect and imperfect knowledge: Oligopolies have perfect knowledge of their own cost and demand functions, but their inter-firm information may be incomplete. If firms in an oligopoly collude, information between firms then may become perfect.

  7. Contestable market - Wikipedia

    en.wikipedia.org/wiki/Contestable_market

    [example needed] The more contestable a market is, the closer it will be to a perfectly contestable market. Some economists argue that determining price and output is actually dependent not on the type of market structure (whether it is a monopoly or perfectly competitive market) but on the threat of competition. [2]

  8. Total revenue - Wikipedia

    en.wikipedia.org/wiki/Total_revenue

    A perfectly competitive firm faces a demand curve that is infinitely elastic.That is, there is exactly one price that it can sell at – the market price. At any lower price it could get more revenue by selling the same amount at the market price, while at any higher price no one would buy any quantity.

  9. Zero-profit condition - Wikipedia

    en.wikipedia.org/wiki/Zero-profit_condition

    More and more firms will enter until the economic profit per firm has been driven down to zero by competition. Conversely, if firms are making negative economic profit, enough firms will exit the industry until economic profit per firm has risen to zero. This description represents a situation of almost perfect competition.
