Product differentiationIn economics and marketing, product differentiation (or simply differentiation) is the process of distinguishing a product or service from others to make it more attractive to a particular target market. This involves differentiating it from competitors' products as well as from a firm's other products. The concept was proposed by Edward Chamberlin in his 1933 book, The Theory of Monopolistic Competition. Firms have different resource endowments that enable them to construct specific competitive advantages over competitors.
Cournot competitionCournot competition is an economic model used to describe an industry structure in which companies compete on the amount of output they will produce, which they decide on independently of each other and at the same time. It is named after Antoine Augustin Cournot (1801–1877) who was inspired by observing competition in a spring water duopoly. It has the following features: There is more than one firm and all firms produce a homogeneous product, i.e., there is no product differentiation; Firms do not cooperate, i.
DuopolyA duopoly (from Greek δύο, duo "two" and πωλεῖν, polein "to sell") is a type of oligopoly where two firms have dominant or exclusive control over a market, and most (if not all) of the competition within that market occurs directly between them. Duopoly is the most commonly studied form of oligopoly due to its simplicity. Duopolies sell to consumers in a competitive market where the choice of an individual consumer choice cannot affect the firm in a duopoly market, as the defining characteristic of duopolies is that decisions made by each seller are dependent on what the other competitor does.
Monopoly profitMonopoly profit is an inflated level of profit due to the monopolistic practices of an enterprise. Traditional economics state that in a competitive market, no firm can command elevated premiums for the price of goods and services as a result of sufficient competition. In contrast, insufficient competition can provide a producer with disproportionate pricing power. Withholding production to drive prices higher produces additional profit, which is called monopoly profits.
Brand loyaltyIn marketing, brand loyalty describes a consumer's positive feelings towards a brand, and their dedication to purchasing the brand's products and/or services repeatedly, regardless of deficiencies, a competitor's actions, or changes in the environment. It can also be demonstrated with other behaviors such as positive word-of-mouth advocacy. Corporate brand loyalty is where an individual buys products from the same manufacturer repeatedly and without wavering, rather than from other suppliers.
