Consumer network¶

Exploiting consumer networks for marketing purposes, through techniques such as viral marketing, word-of-mouth marketing, or network marketing, is increasingly experimented with by marketers, to the extent that "some developments in customer networking are ahead of empirical research, and a few seem ahead even of accepted theory".

Core Idea¶

Consumer network is treated here as the recurring formal models and representations identity summarized by this source-grounded definition: Exploiting consumer networks for marketing purposes, through techniques such as viral marketing, word-of-mouth marketing, or network marketing, is increasingly experimented with by marketers, to the extent that "some developments in customer networking are ahead of empirical research, and a few seem ahead even of accepted theory". The notion of consumer networks expresses the idea that people's embeddedness in social networks affects their behavior as consumers.

How would you explain it like I'm…

Friends Change What We Buy

People buy things partly because their friends have them or talk about them. A consumer network is all the friend connections that pass these ideas around. Companies try to find the popular kids that lots of others listen to, so the word spreads.

How Friends Shape Shopping

A consumer network is the web of friends and contacts that shapes what people buy. People share information and copy each other, so one person's choice can spread to others. That means what people buy isn't just decided by each person alone. Companies try to use this with things like word-of-mouth and viral marketing, and they especially try to reach people who know lots of others and are trusted, called opinion leaders. Companies are trying these ideas faster than researchers have been able to study them.

Social Networks in Consumer Demand

The idea of a consumer network is that people's place in social networks affects how they behave as buyers. Sharing information and imitating others can change demand and market outcomes in ways that the standard economic theory of consumer choice, which treats each buyer as deciding alone, does not account for. Marketers try to exploit these networks through viral marketing, word-of-mouth marketing and network marketing, often by targeting opinion leaders who have many contacts and a good reputation. Practice has run ahead of research, and economic studies on the topic are limited. When economists add consumer networks to standard models, they find effects on market structure, market dynamics and firms' profit-maximizing choices.

Consumer networks capture the fact that consumers are embedded in social networks, so that interactions such as information exchange and imitation shape demand and market outcomes in ways neoclassical consumer-choice theory does not model. Marketers increasingly experiment with exploiting these networks through viral, word-of-mouth and network marketing, a key task being to target consumption opinion leaders, individuals with many contacts and positive reputation. By one characterization, some developments in customer networking are ahead of empirical research, and a few seem ahead even of accepted theory. Economic research on the topic is limited, but attempts to incorporate consumer networks into standard microeconomic models have produced notable implications for market structure, market dynamics and firms' profit-maximizing decisions. The concept is thus specifically the network-mediated dependence of consumer behavior and its exploitation in marketing, not networks in general.

Scope of Application¶

Economics. A 2007 laboratory experiment found that increased density of consumer networks can reduce market inefficiencies caused by moral hazard.
Economics. In another model, which incorporates small world consumer networks into the profit function of the firm, it has been demonstrated that the density of the network significantly affects the optimal price.
Marketing. Exploiting consumer networks for marketing purposes, through techniques such as viral marketing, word-of-mouth marketing, or network marketing, is increasingly experimented with by marketers, to the extent that "some developments in customer.
Economics. In attempts to incorporate consumer networks into standard microeconomic models, some interesting implications have been found concerning market structure, market dynamics and the firm's profit maximizating decision.
Economics. It has been shown that under certain assumptions the structure of the consumer network can affect market structure.

Clarity¶

A clear use of Consumer network names the carrier, the operative relation, and the conditions under which the source treats the identity as present. The minimal definition is Exploiting consumer networks for marketing purposes, through techniques such as viral marketing, word-of-mouth marketing, or network marketing, is increasingly experimented with by marketers, to the extent that "some developments in customer networking are ahead of empirical research, and a few seem ahead.

Manages Complexity¶

Consumer network compresses multiple formal models and representations details into a stable diagnostic relation. The source shows both the central mechanism—a 2007 laboratory experiment found that increased density of consumer networks can reduce market inefficiencies caused by moral hazard.—and the practical consequence—in certain scenarios, where consumers have a higher inclination to compare their habitually consumed product to that of their acquaintances, the equilibrium market structure can switch.

Abstract Reasoning¶

Type the carrier. Identify the formal models and representations entities to which the claim applies.
State the relation. Use the source-grounded identity: Exploiting consumer networks for marketing purposes, through techniques such as viral marketing, word-of-mouth marketing, or network marketing, is increasingly experimented with by marketers, to the extent that "some developments in customer networking are ahead of empirical research, and a few seem ahead even of accepted theory".

Knowledge Transfer¶

Within the home domain. Knowledge about Consumer network transfers literally when a new case preserves the same carrier type, relation, and recognition test. A 2007 laboratory experiment found that increased density of consumer networks can reduce market inefficiencies caused by moral hazard. In another model, which incorporates small world consumer networks into the profit function of the firm, it has been demonstrated that the density of the network significantly affects the optimal price the firm should charge and the optimal referral fee (paid to consumers who can convince another one to buy).

Neighborhood in Abstraction Space¶

Consumer network sits in a sparse region of the domain-specific corpus (62^nd percentile for distinctiveness): few abstractions share its structure, so a faithful description tends to retrieve it precisely.
