A price war is a form of market competition in which companies within an industry engage in aggressive pricing strategies, “characterized by the repeated cutting of prices below those of competitors”. This leads to a vicious cycle, where each competitor attempts to match or undercut the price of the other. Competitors are driven to follow the initial price-cut due to the downward pricing pressure, referred to as “price-cutting momentum”. Heil and Helsen (2001) proposed that a price war exists only if one or more of a set of qualitative conditions are satisfied. These conditions include: (1) a primary focus on competitors rather than consumers, (2) undesirability of pricing interactions for competitors, (3) absence of intention to start a price war by any competitor, (4) violation of industry norms through competitive interactions, (5) accelerated pricing interactions in comparison to the usual pace, (6) a downward direction of pricing, and (7) unsustainable pricing interplay. While price wars can offer short-term benefits to consumers by providing them with lower prices, they can have a negative impact on the companies involved by reducing their profit margins. Moreover, the negative effects of price wars on companies can extend beyond the short term, as the companies involved may struggle to recover their lost profits and maintain their market share. Firms may be cautious when engaging in price wars as this competition can lead to prices that are unsustainable for long-term profitability.

Causes

The main reasons that price wars occur are:

Reactions to price challenges

The first reaction to a price reduction should always be to consider the following: Has the competitor decided upon a long-term price reduction or is this just a short-term promotion? If the competitor has implemented a short-term promotion, the ideal response is to monitor the competitor's price changes and maintain prices at the current level. Price wars often begin when simple promotional activities are misunderstood as major strategic changes. If the competitor is implementing a long-term price change, the following reactions may be suitable:

Effects of price wars

Empirical studies suggest that price wars can significantly damage the companies that practice such behaviour. Notably, price wars can have some short term benefits for firms as it allows them to quickly turnover inventory, alleviate financial pressure, increase social purchasing power, and may compel firms to enhance their production efficiency. But these short term gains are ultimately offset by long term losses. In the long run, price wars can cause companies to incur losses in their margins, customer equity, innovation capabilities and competitive advantage. Victims of price wars may be downgraded in the market, and even incur bankruptcy. But the companies that involve themselves in price wars are not the only affected parties, as suppliers and investors will also be impacted. This can lead to compromised company image and reputation over the long run. Overall, society may suffer from less efficient allocation of resources as the resources that were poured into participating in a price war could have been allocated elsewhere. In the short term, consumers appear to benefit from lower prices during a price war. However, in the long run, consumers are likely to form unrealistic reference prices and may be faced with lower quality products.

Examples of price wars

Price wars are prevalent in many industries, with academic literature citing cases in market segments, including: electricity, telecommunications, automotive, and airlines. Some key examples include:
