The main reasons that price wars occur are: •
Homogenous products: Where products are homogenous, and product
substitution between firms is high, then the
price elasticity of demand will also be high. As a result, if one company in an industry lowers its prices, other firms offering similar products must also reduce their prices to retain their
market share. •
Penetration pricing: If a firm is trying to enter an established market, it may offer lower prices than existing brands to incentivise consumers to switch to their product. •
Oligopoly: If the industry structure is oligopolistic (that is, has few major competitors), the
players will closely monitor each other's prices and be prepared to respond to any price cuts. :*Applying
game theory, two oligopolistic firms that engage in a price war will often find themselves in a kind of
prisoner’s dilemma. Indeed, if Firm A reduces its prices whilst competitor, Firm B, doesn’t reduce its prices, then Firm A can capture market share. And, if Firm A reduces its prices, then Firm B must reduce its prices to avoid being eliminated from the market. The
equilibrium is such that both firms adopt a low-price strategy to protect themselves. Predatory pricing on the international market is called
dumping. That is, when a foreign company sells a product in a domestic market at a price below market value, and in doing so, causes injury to the industry in the domestic market. ==Reactions to price challenges==
