and Erik Brynjolfsson found that bundling was particularly effective for digital information goods with close to zero marginal cost, and could enable a bundler with an inferior collection of products to drive even superior quality goods out of the market place. Most firms are multi-product or multi-service companies faced with the decision whether to sell products or services separately at individual prices or whether combinations of products should be marketed in the form of "bundles" for which a "bundle price" is asked. Price bundling plays an increasingly important role in many industries (e.g. banking, insurance, software, automotive) and some companies even build their business strategies on bundling. In bundle pricing, companies sell a package or set of goods or services for a lower price than they would charge if the customer bought all of them separately. Pursuing a bundle pricing strategy allows a business to increase its profit by using a discount to induce customers to buy more than they otherwise would have.


Rationale

Bundling is most successful when: *There are
economies of scale In microeconomics, economies of scale are the cost advantages that enterprises obtain due to their scale of operation, and are typically measured by the amount of Productivity, output produced per unit of cost (production cost). A decrease in ...
in production. *There are economies of scope in distribution. This can be seen in consumer electronics bundles where a big box electronics store offers all of the components for a home theatre setup (DVD player, flatscreen TV, surround sound speakers, receiver, subwoofer) for a lower price than if each component were to be purchased separately. The big box electronics store can exploit its economies of scope, as they distribute and sell a huge range of home theatre products. *The Marginal costs of bundling are low. * Production set-up costs are high. *Customer acquisition costs are high. *Consumers appreciate the resulting simplification of the purchase decision and benefit from the joint performance of the combined product or service. This is particularly the case when a non-specialist consumer has
information asymmetry In contract theory, mechanism design, and economics, an information asymmetry is a situation where one party has more or better information than the other. Information asymmetry creates an imbalance of power in transactions, which can sometimes c ...
when trying to buy all of the components of a home theatre (speakers, connection cables, speaker wire). He/she would need to learn about all of the product specifications and the requirements for accessories used with the main items. For example, with Home Theatre in a Box, a consumer can feel confident that all of the included speakers are of the correct impedance and power rating and that all of the included cables are the correct models. While many well-known examples of bundling are all products or services from the same store or provider, such as the sports package for a car or a grocery store's gift basket, in some cases, cross-industry bundles are assembled and sold. For example, some

have vacation tour bundles that may include air tickets, rail tickets, a rental car, hotels, restaurants, museum and sightseeing attraction tickets and live music event tickets. These bundles include products and services from the transportation, accommodation, tourism, food service and entertainment industries. Consumers have heterogeneous demands and such demands for different parts of the bundle product are inversely correlated. For example, assume consumer A values a word processor software at $100 and a spreadsheet processor at $60, while consumer B values a word processor at $60 and spreadsheet at $100. Seller can generate a maximum revenue of only $240 by setting a $60 price for each product—both consumers will buy both products. Revenue cannot be increased without bundling because as the seller increases the price above $60 for one of the goods, one of the consumers will refuse to buy it. With bundling, a seller can generate revenue of $320 by bundling the products together and selling the bundle at $160. Thus, bundling can be considered a form of

. Venkatesh and Mahajan reviewed the research on bundle design and pricing in 2009. A 1997 study by Mercer Management Consulting, in Massachusetts stated that good bundles have five elements: (1) the package is worth more than the "sum of its parts" for the consumer; (2) the bundle brings order and simplicity to a set of confusing or tedious choices; (3) the bundle solves a problem for the consumer; (4) the bundle is focused and lean in an effort to avoid carrying or including options, goods or services the consumer has no use for; and (5) the bundle generates interest or even controversy. Number 1 can be read as simply that a bundle should cost less than buying each item separately; however, even if the bundle were to cost the same in dollars, a bundle may still be an appealing value proposition for a consumer, as they do not have to hand-pick each accessory and add-on item (this is the 2nd and 3rd point). Bundling is often thought of mainly as a value pricing strategy, in that product bundles often cost less than if each item were purchased separately. However, bundling can also have other strategic advantages. For example, when a grocery store is making up a gift basket, they can use the design of the basket item list as a way to promote new products or brands that a customer may not know or as a way to liquidate merchandise that is not selling well. Also, even though many bundles are less expensive than all of the items if purchased separately, in some cases the bundle costs more than if each item was purchased separately; this tactic is particularly effective in high-end retailing where

and prestige pricing elements come into play. A well-off home theatre enthusiast with a very high budget may find a $10,000 home theatre package attractive, even if it costs a bit more than buying each item separately, because this is an impressive total cost.


Varieties

*Pure bundling occurs when a consumer can only purchase the entire bundle or nothing **Joint bundling is a subcategory of pure bundling in which the two products are offered together for one bundled price **Leader bundling is a subcategory of pure bundling in which a leader product is offered for discount if purchased with a non-leader product, accessory or other item. ***Mixed-leader bundling is a variant of leader bundling with the added possibility of buying the leader product on its own. *Mixed bundling occurs when consumers are offered a choice between purchasing the entire bundle or one of the separate parts of the bundle. Bundling in political economy is a type of product bundling in which the "product" is a candidate in an election who markets his or her bundle of attributes and political positions to the voters. For example, a political candidate may market herself as a centrist candidate by ensuring she/he has centrist social, economic, and law enforcement positions.


Advantages and disadvantages

Advantages: * Help the company sell some unpopular products and speed up inventory clearance. Product bundling combines the best-selling products and unpopular products with less inventory by setting reasonable prices to increase the attractiveness, so that consumers can buy combination products to help the company reduce inventory. * Help the company generate more sales and maximize profits. Product bundling can maximize consumer surplus so that consumers feel that they have obtained additional items, so customers are more likely to spend a total of one time to purchase multiple products. This can help the company increase total sales revenue by increasing the average order value, average transaction value, and the amount of each transaction, because multiple products are more expensive than a single product. * Enable the company to promote more differentiated products with lower marketing costs. The company can spend the same energy and cost to promote two or more products at the same time. * Help consumers reduce decision-making pressure. Merchants use matching algorithms to set up bundled products that meet the needs of consumers, thereby guiding customers to choose options that meet their needs and reducing their decision fatigue. Bundles have the effect of reducing search costs. Disadvantages to the consumer: * Decreases competition. * Reduces
consumer choice The theory of consumer choice is the branch of microeconomics that relates preferences to consumption expenditures and to consumer demand curves. It analyzes how consumers maximize the desirability of their consumption (as measured by their pr ...
; consumers may be forced to buy bundles which don't contain all the things they wanted, and contain things they don't want, and may even be pushed into buying inferior products. For example, two companies both sell a bundle containing a computer and an operating system, but one has poor-quality hardware and one has poor-quality software. The consumer wants to buy each company's good product, but can't unless they pay for two computers and two operating systems and throw one of each away. A new company which sells only hardware or only operating systems also has to persuade the consumer to throw away a purchased product; this is a barrier to market entry. * Can drive up consumer costs. * A method of

. Disadvantages to the seller: * Product bundling may lead to the cannibalization of branded products. These products can be purchased outside of the bundled sales package. For example, if a company sells bundled products and individual products at the same time, then the bundled products will get more sales, which will reduce the profit of the individual products. * When consumers cannot buy certain products individually, they may not buy them because they feel that the bundled sales package forces them to buy more products.

or other source for playing back movies, a HTIB package provides all of the electronics hardware, speakers and cables needed to set up a home cinema. There are three grades of HTIB bundles: economy bundles, aimed at the lowest price point; mid-tier bundles, the most common type; and higher-cost HTIB bundles made by BOSE and other higher-end manufacturers. At the economy grade HTIB package, the customer is provided with a basic home theatre set-up, with modest sound quality and relatively few options for adjusting the sound. The mid-tier and upper-tier packages offer better performance and more set-up options. All three HTIB tiers, though, have a similar value proposition for the buyer: the HTIB package ensures that all of the speakers are of the correct impedance and power handling capabilities, the cables are of the correct type, and the crossover points and other technical details have been set up by the manufacturer. The most serious home theatre enthusiasts do not typically buy HTIB bundles, as they are a more sophisticated target market. As such, the most serious home cinema-philes typically purchase each component (power amplifiers, speakers, subwoofer cabinet, speaker cables) separately, so that they can choose which items meet their specific movie-watching goals. For example, a serious home theatre enthusiast may wish to have a large cabinet subwoofer enclosure with heavy bracing, a type and size of subwoofer cabinet that would not be found in any HTIB bundle due to its large size and high cost. As well, a serious home theatre enthusiast may wish to have a powered subwoofer with a user-adjustable crossover, a "subsonic" filter and other higher-cost advanced features.


Market power and competitiveness

In oligopolistic and monopolistic industries, product bundling can be seen as an unfair use of market power because it limits the choices available to the consumer. In these cases it is typically called product tying. Some forms of product bundling have been subject to litigation regarding abuses of market share.

The progress towards complete cable, internet, and telephone packages gave subscribers many more options as well as offering hundreds of channels. The "package" price depends on the level of service a customer prefers within each bundle. The services range from low speed internet and minimum channels to high speed internet and the addition of many premium channels.
