Pricing strategies in the context of Marguerite Martyn

Predatory pricing, also known as price slashing, is a commercial pricing strategy which involves reducing the retail prices to a level lower than competitors to eliminate competition. Selling at lower prices than a competitor is known as undercutting. This is where an industry dominant firm with sizable market power will deliberately reduce the prices of a product or service to loss-making levels to attract all consumers and create a monopoly. For a period of time, the prices are set unrealistically low to ensure competitors are unable to effectively compete with the dominant firm without suffering a substantial loss. The aim is to force existing or potential competitors within the industry to abandon the market so that the dominant firm may establish a stronger market position and create further barriers to entry. Once competition has been driven from the market, consumers are forced into a monopolistic market where the dominant firm can safely increase prices to recoup its losses.

The critical difference between predatory pricing and other market strategies is the potential for consumer harm in the long-term. Despite the initial buyer's market created through firms' competing for consumer preference, as the price war favours the dominant firm, consumers will be forced to accept fewer options and higher prices for the same goods and services in the monopolistic market. If the strategy is executed successfully, predatory pricing can cause consumer harm and is, therefore, considered anti-competitive in many jurisdictions, making the practice illegal under numerous competition laws.

A loss leader (also leader) is a pricing strategy where a product is sold at a price below its market cost to stimulate other sales of more profitable goods or services. With this sales promotion/marketing strategy, a "leader" is any popular article, i.e., sold at a low price to attract customers.

One use of a loss leader is to draw customers into a store where they are likely to buy other goods. The vendor expects that the typical customer will purchase other items at the same time as the loss leader and that the profit made on these items will be such that an overall profit is generated for the vendor.

Cost-plus pricing is a pricing strategy by which the selling price of a product is determined by adding a specific fixed percentage (a "markup") to the product's unit cost. Essentially, the markup percentage is a method of generating a particular desired rate of return. An alternative pricing method is value-based pricing.

Cost-plus pricing has often been used for government contracts (cost-plus contracts), and has been criticized for reducing incentive for suppliers to control direct costs, indirect costs and fixed costs whether related to the production and sale of the product or service or not.

Freemium, a portmanteau of the words "free" and "premium", is a pricing strategy by which a basic product or service is provided free of charge, but money (a premium) is charged for additional features, services, or virtual (online) or physical (offline) goods that expand the functionality of the free version of the software. This business model has been used in the software industry since the 1980s. A subset of this model used by the video game industry is called free-to-play.

The ethics of freemium, especially the free-to-play subset, were criticized by Touch Arcade and Business Insider in 2014 and 2015.

Price discrimination, known also by several other names, is a microeconomic pricing strategy whereby identical or largely similar goods or services are sold at different prices by the same provider to different buyers, based on which market segment they are perceived to be part of. Price discrimination is distinguished from product differentiation by the difference in production cost for the differently priced products involved in the latter strategy. Price discrimination essentially relies on the variation in customers' willingness to pay and in the elasticity of their demand. For price discrimination to succeed, a seller must have market power, such as a dominant market share, product uniqueness, sole pricing power, etc.

Some prices under price discrimination may be lower than the price charged by a single-price monopolist. Price discrimination can be utilized by a monopolist to recapture some deadweight loss. This pricing strategy enables sellers to capture additional consumer surplus and maximize their profits while offering some consumers lower prices.
