In 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 . [1]
Firms have different resource endowments that enable them to construct specific competitive advantages over competitors. [2] Resource endowments allow firms to be different, which reduces competition and makes it possible to reach new segments of the market. Thus, differentiation is the process of distinguishing the differences of a product or offering from others, to make it more attractive to a particular target market. [3]
Although research in a niche market may result in changing a product in order to improve differentiation, the changes themselves are not differentiation. Marketing or product differentiation is the process of describing the differences between products or services, or the resulting list of differences. This is done in order to demonstrate the unique aspects of a firm's product and create a sense of value. Marketing textbooks are firm on the point that any differentiation must be valued by buyers [3] (a differentiation attempt that is not perceived does not count). The term unique selling proposition refers to advertising to communicate a product's differentiation. [4]
In economics, successful product differentiation leads to competitive advantage and is inconsistent with the conditions for perfect competition, which include the requirement that the products of competing firms should be perfect substitutes. There are three types of product differentiation:
The brand differences are mostly minor; they can be merely a difference in packaging or an advertising theme. The physical product need not change, but it may. Differentiation is due to buyers perceiving a difference; hence, causes of differentiation may be functional aspects of the product or service, how it is distributed and marketed, or who buys it. The major sources of product differentiation are as follows.
The objective of differentiation is to develop a position that potential customers see as unique. The term is used frequently when dealing with freemium business models, in which businesses market a free and paid version of a given product. Given they target the same group of customers, it is imperative that free and paid versions be effectively differentiated.
Differentiation primarily affects performance through reducing directness of competition: as the product becomes more different, categorization becomes more difficult and hence draws fewer comparisons with its competition. A successful product differentiation strategy will move a product from competing based primarily on price to competing on non-price factors (such as product characteristics, distribution strategy, or promotional variables).
Most people would say that the implication of differentiation is the possibility of charging a price premium; however, this is an over-simplification. If customers value the firm's offer, they will be less sensitive to aspects of competing offers; price may not be one of these aspects. Differentiation makes customers in a given segment have a lower sensitivity to other features (non-price) of the product. [6]
Edward Chamberlin’s (1933) seminal work on monopolistic competition mentioned the theory of differentiation, which maintained that for available products within the same industry, customers may have different preferences. However, a generic strategy of differentiation popularized by Michael Porter (1980) proposed that differentiation is any product (tangible or intangible) perceived as “being unique” by at least one set of customers. Hence, it depends on customers' perception of the extent of product differentiation. Even until 1999, the consequences of these concepts were not well understood. In fact, Miller (1986) proposed marketing and innovation as two differentiation strategies, which was supported by some scholars like Lee and Miller (1999). Mintzberg (1988) proposed more specific but broad categories: quality, design, support, image, price, and undifferentiated products, which received support from Kotha and Vadlamani (1995). However, IO literature (Ethiraj & Zhu, 2008; Makadok, 2010, 2011) did deeper analysis into the theory and explored a clear distinction between the wide use of vertical and horizontal differentiation. [7]
Vertical product differentiation can be measured objectively by a consumer. For example, when comparing two similar products, the quality and price can clearly be identified and ranked by the customer. If both A and B products have the same price to the consumer, then the market share for each one will be positive, according to the Hotelling model. The major theory in this is that all consumers prefer the higher quality product if two distinct products are offered at the same price. A product can differ in many vertical attributes such as its operating speed. What really matters is the relationship between consumers' willingness to pay for improvements in quality and the increase in cost per unit that comes with such improvements. Therefore, the perceived difference in quality is different among different consumers, so it is objective. [8] For example, a green product might have a lower or zero negative effect on the environment; however, it may turn out to be inferior to other products in other aspects. Hence, the product's appeal also depends on the way it is advertised and the social pressure felt by a potential consumer. Even one vertical differentiation can be a decisive factor in purchasing. [9]
Horizontal differentiation seeks to affect an individual's subjective decision-making, that is the difference cannot be measured in an objective way. For example, different color versions of the same iPhone or MacBook. A lemon ice cream is not superior to a chocolate ice cream, is completely based on the user's preference. A restaurant may price all of its desserts at the same price and lets the consumer freely choose its preferences since all the alternatives cost the same. [10] A clear example of Horizontal Product Differentiation can be seen when comparing Coca Cola and Pepsi: if priced the same then individuals will differentiate between the two based purely on their own taste preference.
Whilst Product differentiation is typically broken into two types Vertical and Horizontal, it's important to note that all products exhibit a combination of both and they are not the only way to define differentiation. Another way to differentiate a product is through spatial differentiation. Spatial Product Differentiation is using a geographical location as a way to differentiate. [11] An example of Spatial Differentiation is a firm locally sourcing inputs and producing their product.
According to research conducted by combining mathematics and economics, decisions of pricing depend on the substitutability between products, the level of substitutability varies as the degree of differentiation between firms’ products change. A firm cannot charge a higher price if products are good substitutes, conversely as a product deviates from others in the segment producers can begin to charge a higher price. The lower non-cooperative equilibrium price the lower the differentiation. For this reason, firms might jointly raise prices above the equilibrium or competitive level by coordination between themselves. They have a verbal or written collusion agreement between them. Firms operating in a market of low product differentiation might not coordinate with others, which increases the incentive to cheat the collusion agreement. If a firm slightly lowers there prices, they can capture a large fraction of the market and obtain short term profits if the products are highly substitutable. [12]
Product differentiation within a given market segment can have both positive and negative affects on the consumer. From the producers perspective building a different product compared to competitors can create a competitive advantage which can result in higher profits. Through differentiation consumers gain greater value from a product, however this leads to increased demand and market segmentation which can cause anti-competitive effects on price. [13] From this perspective greater diversity leads to more choices which means each individual can purchase a product better suited to themselves, the negative to this is prices within the market segment tend to rise. The level of differentiation between goods can also affect demand. For example within grocery stores, If a category of goods is relatively nondifferentiated then a high amount of assortment depth leads to less sales. [14]
During the 1990s, steps taken by government on deregulation and European integration persuaded banks to compete for deposits on many factors like deposit rates, accessibility and the quality of financial services. [15]
In this example using the Hotelling model, one feature is of variety (location) and one feature of quality (remote access). Remote access using bank services via postal and telephonic services like arranging payment facilities and obtaining account information). In this model, banks cannot become vertically differentiated without negatively affecting horizontal differentiation between them. [15]
Horizontal differentiation occurs with the location of bank's branch. Vertical differentiation, in this example, occurs whenever one bank offers remote access and the other does not. With remote access, it can spur a negative interaction between transportation rate and taste for quality: customers who have higher taste for remote access face a lower transportation rate. [15]
A depositor with a high (low) taste for remote access has low (high) linear transportation costs. Different equilibria emerge as the result of two effects. On the one hand, introducing remote access steals depositors from your competitor because the product specification becomes more appealing (direct effect). On the other hand, banks become closer substitutes (indirect effect). First, banks become closer substitutes as the impact of linear transportation costs decreases. Second, deposit rate competition is affected by the size of the quality difference. These two effects, "stealing" depositors versus "substitutability" between banks, determines the equilibrium. For low and high values of the ratio quality difference to transportation rate, only one bank offers remote access (specialization). Intermediate (very low) values of the ratio quality difference to transportation costs yield universal (no) remote access. [15]
This competition is a two factor game: one is of offering of remote access and the other is of deposit rates. Hypothetically, there will be two consequential scenarios if only one bank offers remote access. First, the bank gains a positive market share for all types of remote access, giving rise to horizontal dominance. This occurs when the transportation cost prevail over the quality of service, deposit rate and time. Second, vertical dominance comes into picture when the bank that is not offering remote access gets the entire market for depositors who have lowest preference for remote access. That is when the quality service, deposit rate and time prevails over the cost of transportation. [15]
Monopolistic competition is a type of imperfect competition such that there are many producers competing against each other, but selling products that are differentiated from one another and hence are not perfect substitutes. In monopolistic competition, a company takes the prices charged by its rivals as given and ignores the impact of its own prices on the prices of other companies. If this happens in the presence of a coercive government, monopolistic competition will fall into government-granted monopoly. Unlike perfect competition, the company maintains spare capacity. Models of monopolistic competition are often used to model industries. Textbook examples of industries with market structures similar to monopolistic competition include restaurants, cereals, clothing, shoes, and service industries in large cities. The "founding father" of the theory of monopolistic competition is Edward Hastings Chamberlin, who wrote a pioneering book on the subject, Theory of Monopolistic Competition (1933). Joan Robinson published a book The Economics of Imperfect Competition with a comparable theme of distinguishing perfect from imperfect competition. Further work on monopolistic competition was undertaken by Dixit and Stiglitz who created the Dixit-Stiglitz model which has proved applicable used in the sub fields of international trade theory, macroeconomics and economic geography.
In economics, imperfect competition refers to a situation where the characteristics of an economic market do not fulfil all the necessary conditions of a perfectly competitive market. Imperfect competition causes market inefficiencies, resulting in market failure. Imperfect competition usually describes behaviour of suppliers in a market, such that the level of competition between sellers is below the level of competition in perfectly competitive market conditions.
Price discrimination is a microeconomic pricing strategy where identical or largely similar goods or services are sold at different prices by the same provider in different market segments. Price discrimination is distinguished from product differentiation by the more substantial difference in production cost for the differently priced products involved in the latter strategy. Price differentiation essentially relies on the variation in the customers' willingness to pay and in the elasticity of their demand. For price discrimination to succeed, a firm must have market power, such as a dominant market share, product uniqueness, sole pricing power, etc. All prices under price discrimination are higher than the equilibrium price in a perfectly competitive market. However, some prices under price discrimination may be lower than the price charged by a single-price monopolist. Price discrimination is utilised by the monopolist to recapture some deadweight loss. This Pricing strategy enables firms to capture additional consumer surplus and maximize their profits while benefiting some consumers at lower prices. Price discrimination can take many forms and is prevalent in many industries, from education and telecommunications to healthcare.
Horizontal integration is the process of a company increasing production of goods or services at the same level of the value chain, in the same industry. A company may do this via internal expansion, acquisition or merger.
In microeconomics, management and international political economy, vertical integration is an arrangement in which the supply chain of a company is integrated and owned by that company. Usually each member of the supply chain produces a different product or (market-specific) service, and the products combine to satisfy a common need. It contrasts with horizontal integration, wherein a company produces several items that are related to one another. Vertical integration has also described management styles that bring large portions of the supply chain not only under a common ownership but also into one corporation.
Pricing is the process whereby a business sets the price at which it will sell its products and services, and may be part of the business's marketing plan. In setting prices, the business will take into account the price at which it could acquire the goods, the manufacturing cost, the marketplace, competition, market condition, brand, and quality of product.
In business, a competitive advantage is an attribute that allows an organization to outperform its competitors.
Porter's Five Forces Framework is a method of analysing the operating environment of a competition of a business. It draws from industrial organization (IO) economics to derive five forces that determine the competitive intensity and, therefore, the attractiveness of an industry in terms of its profitability. An "unattractive" industry is one in which the effect of these five forces reduces overall profitability. The most unattractive industry would be one approaching "pure competition", in which available profits for all firms are driven to normal profit levels. The five-forces perspective is associated with its originator, Michael E. Porter of Harvard University. This framework was first published in Harvard Business Review in 1979.
Marketing strategy is an organization's promotional efforts to allocate its resources across a wide range of platforms, channels to increase its sales and achieve sustainable competitive advantage within its corresponding market.
Anti-competitive practices are business or government practices that prevent or reduce competition in a market. Antitrust laws ensure businesses do not engage in competitive practices that harm other, usually smaller, businesses or consumers. These laws are formed to promote healthy competition within a free market by limiting the abuse of monopoly power. Competition allows companies to compete in order for products and services to improve; promote innovation; and provide more choices for consumers. In order to obtain greater profits, some large enterprises take advantage of market power to hinder survival of new entrants. Anti-competitive behavior can undermine the efficiency and fairness of the market, leaving consumers with little choice to obtain a reasonable quality of service.
In microeconomics, two goods are substitutes if the products could be used for the same purpose by the consumers. That is, a consumer perceives both goods as similar or comparable, so that having more of one good causes the consumer to desire less of the other good. Contrary to complementary goods and independent goods, substitute goods may replace each other in use due to changing economic conditions. An example of substitute goods is Coca-Cola and Pepsi; the interchangeable aspect of these goods is due to the similarity of the purpose they serve, i.e fulfilling customers' desire for a soft drink. These types of substitutes can be referred to as close substitutes.
Non-price competition is a marketing strategy "in which one firm tries to distinguish its product or service from competing products on the basis of attributes like design and workmanship". It often occurs in imperfectly competitive markets because it exists between two or more producers that sell goods and services at the same prices but compete to increase their respective market shares through non-price measures such as marketing schemes and greater quality. It is a form of competition that requires firms to focus on product differentiation instead of pricing strategies among competitors. Such differentiation measures allowing for firms to distinguish themselves, and their products from competitors, may include, offering superb quality of service, extensive distribution, customer focus, or any sustainable competitive advantage other than price. When price controls are not present, the set of competitive equilibria naturally correspond to the state of natural outcomes in Hatfield and Milgrom's two-sided matching with contracts model.
Market structure, in economics, depicts how firms are differentiated and categorised based on the types of goods they sell (homogeneous/heterogeneous) and how their operations are affected by external factors and elements. Market structure makes it easier to understand the characteristics of diverse markets.
Merger control refers to the procedure of reviewing mergers and acquisitions under antitrust / competition law. Over 130 nations worldwide have adopted a regime providing for merger control. National or supernational competition agencies such as the EU European Commission or the US Federal Trade Commission are normally entrusted with the role of reviewing mergers.
In economics, demand is the quantity of a good that consumers are willing and able to purchase at various prices during a given time. The relationship between price and quantity demand is also called the demand curve. Demand for a specific item is a function of an item's perceived necessity, price, perceived quality, convenience, available alternatives, purchasers' disposable income and tastes, and many other options.
In marketing, a customer value proposition (CVP) consists of the sum total of benefits which a vendor promises a customer will receive in return for the customer's associated payment.
Global marketing is defined as “marketing on a worldwide scale reconciling or taking global operational differences, similarities and opportunities in order to reach global objectives".
The following outline is provided as an overview of and topical guide to marketing:
In marketing, a company’s value proposition is the full mix of benefits or economic value which it promises to deliver to the current and future customers who will buy their products and/or services. It is part of a company's overall marketing strategy which differentiates its brand and fully positions it in the market. A value proposition can apply to an entire organization, parts thereof, customer accounts, or products and services.
Customer cost refers not only to the price of a product, but it also encompasses the purchase costs, use costs and the post-use costs. Purchase costs consist of the cost of searching for a product, gathering information about the product and the cost of obtaining that information. Usually, the highest use costs arise for durable goods that have a high demand on resources, such as energy or water, or those with high maintenance costs. Post-use costs encompass the costs for collecting, storing and disposing of the product once the item has been discarded.
