The impact of social media conversations on consumer brand choices

This paper estimates the impact of social media conversations on consumer valuation of brand characteristics and demand for carbonated soft drinks (CSDs). We formulate a random coefficient, discrete choice model of consumer demand that includes social media conversations, and estimate it matching Nielsen sales data on carbonated soft drinks to social media conversations on Facebook, Twitter, and YouTube. Empirical results indicate that consumers’ conversations about brands and nutritional aspects of CSDs have a significant impact on their valuation of brand characteristics and ultimately on their choices of CSDs. These findings have important implications not only for firms using social media as a strategic tool for effective brand promotion and product design but also for public health policies aimed at reducing the consumption of sugary beverages and high-calorie foods.     

The impact of membership fees on consumer attitude and choice

This study examined the impact of membership fees on consumer attitude and purchase behavior. Subjects participated in a computerized simulated shopping experiment, and chose between three competing videotape rental stores, receiving feedback about purchase utility on each occasion. Manipulations included the presence or absence of an initial membership-fee requirement at the dominant store and the timing of a lowering of that store's utility to the same level as that offered by a competing establishment. Store loyalty is shown to vary as a function of membership fees and utility changes in a manner consistent with hypotheses generated from prospect, escalation-of-commitment, cognitive-dissonance, and self-perception theories. © 1998 John Wiley & Sons, Inc.     

The provision of information on consumer rights: British experiences

In 1973, the British Government created the official post of Director General of Fair Trading with, inter alia, the power to produce and distribute information and advice to consumers in the United Kingdom. This paper describes how the Office of Fair Trading set out to perform this function, using a variety of media, and the lessons learnt about the consumer's reaction to and absorption of consumer advice material. It finally forecasts the likely trends in demand for consumer information material.

Linguistic barriers to consumer information processing: Information overload in the hispanic population

The ability of individuals to assimilate and process consumer information appears to have finite limits. If consumers are given information which exceeds their processing capacity, information overload is said to exist and results in less effective decision making. The relationship between information overload and linguistic ability was investigated in this study. Americans and Hispanics were presented with varying amounts of consumer information in their native and non-native language. As predicted, information can act as a stressor, affecting decision making in a non-native language prior to affecting decision making in a dominant language. Information overload occurred sooner in Hispanics and Americans when consumer information was presented in their non-dominant language.     

The effect of attribute-based and alternative-based processing on consumer choice in context

The current research proposes that the extent to which consumer choices are affected by the decision process depends on the underlying nature of the choice problem. Specifically, choices resulting from substantial inter-brand comparisons and tradeoff analyses are vulnerable to whether product information is evaluated by attribute- or alternative-based processing. By contrast, choices resulting from a minimal cognitive processing are less sensitive to variations in the decision strategy employed. We test our theory in the well-known domain of choice context effects. Across three studies using multiple operationalizations of the decision process (i.e., information display format, product presentation mode, and processing goal), we find converging evidence that the more cognitively involving compromise choice increases when the environment facilitates attribute- versus alternative-based processing. Conversely, the choice of asymmetrically dominating option, which is characterized by relatively little analytical processing, does not depend on the type of decision strategy highlighted by the task.     

The impact of search costs on consumer behavior: A dynamic approach

Prices for grocery items differ across stores and time because of promotion periods. Consumers therefore have an incentive to search for the lowest prices. However, when a product is purchased infrequently, the effort to check the price every shopping trip might outweigh the benefit of spending less. I propose a structural model for storable goods that takes into account inventory holdings and search. The model is estimated using data on laundry detergent purchases. I find search costs play a large role in explaining purchase behavior, with consumers unaware of the price of detergent on 70 % of their shopping trips. Therefore, from the retailer’s point of view raising awareness of a promotion through advertising and displays is important. I also find a promotion for a particular product increases the consumer’s incentive to search. This change in incentives leads to an increase in category traffic, which from the store manager’s perspective is a desirable side effect of the promotion.     

The impact of advertising on consumer price sensitivity in experience goods markets

In this paper we use Nielsen scanner panel data on four categories of consumer goods to examine how TV advertising and other marketing activities affect the demand curve facing a brand. Advertising can affect consumer demand in many different ways. Becker and Murphy (Quarterly Journal of Economics 108:941–964, 1993) have argued that the “presumptive case” should be that advertising works by raising marginal consumers’ willingness to pay for a brand. This has the effect of flattening the demand curve, thus increasing the equilibrium price elasticity of demand and the lowering the equilibrium price. Thus, “advertising is profitable not because it lowers the elasticity of demand for the advertised good, but because it raises the level of demand.” Our empirical results support this conjecture on how advertising shifts the demand curve for 17 of the 18 brands we examine. There have been many prior studies of how advertising affects two equilibrium quantities: the price elasticity of demand and/or the price level. Our work is differentiated from previous work primarily by our focus on how advertising shifts demand curves as a whole. As Becker and Murphy pointed out, a focus on equilibrium prices or elasticities alone can be quite misleading. Indeed, in many instances, the observation that advertising causes prices to fall and/or demand elasticities to increase, has misled authors into concluding that consumer “price sensitivity” must have increased, meaning the number of consumers’ willing to pay any particular price for a brand was reduced—perhaps because advertising makes consumers more aware of substitutes. But, in fact, a decrease in the equilibrium price is perfectly consistent with a scenario where advertising actually raises each individual consumer’s willingness to pay for a brand. Thus, we argue that to understand how advertising affects consumer price sensitivity one needs to estimate how it shifts the whole distribution of willingness to pay in the population. This means estimating how it shifts the shape of the demand curve as a whole, which in turn means estimating a complete demand system for all brands in a category—as we do here. We estimate demand systems for toothpaste, toothbrushes, detergent and ketchup. Across these categories, we find one important exception to conjecture that advertising should primarily increase the willingness to pay of marginal consumers. The exception is the case of Heinz ketchup. Heinz advertising has a greater positive effect on the WTP of infra-marginal consumers. This is not surprising, because Heinz advertising focuses on differentiating the brand on the “thickness” dimension. This is a horizontal dimension that may be highly valued by some consumers and not others. The consumers who most value this dimension have the highest WTP for Heinz, and, by focusing on this dimension; Heinz advertising raises the WTP of these infra-marginal consumers further. In such a case, advertising is profitable because it reduces the market share loss that the brand would suffer from any given price increase. In contrast, in the other categories we examine, advertising tends to focus more on vertical attributes.

The consumer information deficit: Assessment and policy implications

This paper reports about a research project financially supported by the Federal Ministry for Research and Technology of the FRG as part of the work of a consortium of consumer research teams from several universities. Using the problem of purchasing an automobile as an example, consumer information need and information supply are analyzed in order to delineate the consumer information deficit. Information need is defined as information suitable for reducing risks of purchase perceived by consumers which were ascertained in two surveys. Information supply was analysed by a content analysis of sales brochures, advertisements, and automotive magazines, as well as a study of the information content of sales talks. It turns out that the information supply is unsatisfactory with regard to the information need.Several studies of attempts to reduce the information deficit are also reported. A lab study indicates that required improvements of the information content of sales brochures may help consumers to make better purchase decisions. A videotex information system, which was also investigated, had no influence on purchase decisions, but was still considered useful by consumers.

Das Informationsdefizit der Konsumenten: Erhebung und Folgerungen für die Verbraucherpolitik

Zusammenfassung Es wird über eine Untersuchung berichtet, die im Rahmen des vom BMFT geförderten Forschungsverbundes empirische Verbraucherforschung an der Universität Hohenheim durchgeführt wurde. Ziel der Untersuchung war, die weitverbreitete Behauptung, die Konsumenten hätten ein Informationsdefizit, empirisch zu untersuchen, sowie Möglichkeiten zur Verringerung des Informationsdefizites, falls es ein solches gibt, aufzuzeigen. Die Erhebung des Informationsdefizites geschah am Beispiel des Problems eines Automobilkaufes. Zunächst wurde der Informationsbedarf der Konsumenten erhoben, der operationalisiert wurde als die Menge der Informationen die notwendig sind, um die von allen Konsumenten kollektiv empfundenen Kaufrisiken zu reduzieren. Empfundene Kaufrisiken wurden in einer offenen Befragung ermittelt und durch Befragung einer Zufallsstichprobe von 500 Neuwagenkäufern abgesichert und entsprechend ihrer Bedeutung gewichtet. Dem Informationsbedarf wurde das Informationsangebot gegenübergestellt. Alle bedeutsamen institutionellen Informationsquellen wurden daraufhin untersucht, inwieweit sie Informationen enthalten, die zur Reduktion der von den Konsumenten empfunden Kaufrisiken geeignet sind. Werbeanzeigen, Prospekte sowie Automobiltests wurden einer Inhaltsanalyse unterzogen. Ergänzend wurden Redakteure von Automobilzeitschriften befragt sowie Verkaufgespräche simuliert und auf ihren Informationsgehalt untersucht. Es stellte sich heraus, daß es zahlreiche, von Konsumenten empfundene Kaufrisiken gibt, über die keine oder kaum Informationen erhältlich sind, oder wo die Informationen von eingeschränkter Brauchbarkeit sind, da sie entweder nicht nachprüfbar sind oder technisches Vorverständnis beim Konsumenten voraussetzen. Unter den Kaufrisiken, in bezug auf die das Informationsangebot unbefriedigend ist, finden sich etliche, die von den Konsumenten als besonders wichtig eingestuft werden.Anschließend wird über mehrere Studien berichtet, in denen Maßnahmen zur Verringerung des Informationsdefizites untersucht wurden. Ein Laborexperiment zeigte, daß Informationsauflagen, mit deren Hilfe der Informationsgehalt von Prospekten verbessert wurde, die Kaufentscheidungen der Versuchspersonen verbesserten. Parallel wurde ein Informationssystem in Bildschirmtext untersucht, das allerdings keinen meßbaren Einfluß auf die Qualität der gefällten Kaufentscheidungen hatte. Beide Informationsmaßnahmen wurden von den Versuchspersonen allerdings als nützlich beurteilt. Andere Maßnahmen der Verbraucherinformation, wie persönliche Beratung und Aktivinformation in den Massenmedien, werden zur Verringerung des Informationsdefizites im Bereich der Produktinformation als weniger geeignet angesehen, könnten aber im Bereich der Bedarfsreflexion oder im Bereich der Strukturierung von Konsumproblemen sinnvolle Ergänzungen darstellen. Eine ausführliche Darstellung des Forschungsprojektes in deutscher Sprache findet sich bei Dedler et al. (1984).

The existence and perception of redundancy in consumer information environments

Two studies are reported which examine the existence of attribute redundancy as well as consumers' ability to perceive attribute redundancy in consumer information environments. The results of the first study suggest that attribute redundancy varies widely from product category to product category. The results of the second study suggest that consumers' ability to perceive attribute relationships improves with product knowledge. Unexpected was an observed U-shaped relationship between consumers' perceptions of attribute redundancy and attribute knowledge. Together the results suggest a number of policy implications regarding the value of consumer information programs.     

Examining the impact of consumer debt on parent-child interaction

The purpose of this study was to examine the possible relationship between consumer debt and several aspects of parent-child interaction, namely time spent by parents with their child(ren). affectionate interaction between parents and children and disciplinary parent-child interaction. A small, positive relationship was found between consumer debt and disciplinary parent-child interaction. No meaningful relationship was found between consumer debt and parental time spent with child(ren) or affectionate parental-child interaction. Age and number of children are more reliable correlates of parent-child interaction than is amount of household consumer debt.     

The effects of demographic characteristics on consumer information periodical readership and financial knowledge

A telephone survey of French- and English-speaking households in Quebec was conducted to obtain information about money management practices, of use information sources and knowledge of personal finance terminology. Correlations and regressions were performed on data from 234 interviews. An index of consumer periodical readership was related positively to variables for female respondent, English-speaking, urban residence, income and education in the correlations. A financial knowledge index was related positively to variables for income, education, and the periodical index in the correlations. The knowledge index peaked for the 41–55 years of age category. A two-equation recursive model for periodical readership and financial knowledge was tested. A regression on the periodical index had positive effects for income, education and variables for age 56–64 and 65 and over, and a negative effect for rural location. A regression on the knowledge index had positive effects for the periodical index, income, French-speaking and the variable for age 41–55, and a negative effect for female respondent. The needs of lower income consumers may not be met well by consumer periodicals. In terms of financial knowledge, English-speaking consumers in Quebec may be at a disadvantage relative to French-speaking consumers with similar income levels.     

The influence of negative marketplace information on consumer attitudes toward a service establishment

Market information about service providers and retailers can significantly influence how customers view firms. Prior research indicates that the impact of such information (especially when it is counter to consumers’ initial views of a firm) is dependent upon the nature of the customers’ evaluations, as well as the nature of the information itself. The current study examines these issues in the context of attitudes toward, and negative reviews about, a service provider (a new restaurant chain). An experimental study partially supports prior research findings and suggests a new process using a validated measure distinguishing between hedonic and utilitarian dimensions of attitude. Implications of our results are provided for theory and practice.     

Non-use benefits of mandatory consumer information programs

Government programs requiring detailed information on consumer product labels have become the usual response to: a) the greater awareness and political activity of consumers; b) the greater complexity of consumer products; and c) the emergence of large conglomerate structures within the consumer goods industries. These programs are usually designed by experts to provide consumers with objective facts, presumably to enable analysis of purchase alternatives. Early evidence concerning consumer use of these informative labels suggests that they like them but see them more as an element of security than as an input to the decision process. They want to know that a third party has exercised surveillance over important objective dimensions of the products. The greatest effect such programs may have on the market is through the response of manufacturers. The third party identification of particular product characteristics focuses developmental activity on those features.

Zusammenfassung Wachsende kritische Einstellung und politische Aktivität der Verbraucher, steigende Konsumgütervielfalt und die Konzentrationstendenzen innerhalb der Konsumgüterindustrie veranlassen die staatliche Verbraucherpolitik mehr und mehr, auf detaillierte warenbegleitende Produktinformation hinzuwirken. Zumeist werden Informationsauflagen so ausgestaltet, daß sie die Verbraucher mit objektiven Fakten versorgen und ihnen die vergleichende Beurteilung der Kaufalternativen erleichtern. Erste Befunde über die Reaktion der Verbraucher auf solche Informationen stützen die Vermutung, daß sie sie zwar schätzen, aber doch mehr als ein Element der Sicherheit und nicht so sehr als Entscheidungshilfe betrachten. Sie möchten sichergehen, daß eine dritte Instanz die wichtigsten Produkteigenschaften überwacht hat. In der Reaktion der Anbieter auf solche Maßnahmen liegt vermutlich deren größter Effekt. Denn der Wettbewerb wird solche Produkteigenschaften stärker berücksichtigen, die durch Informationsauflagen hervorgehoben werden.

Exploring the impact of online privacy disclosures on consumer trust

We explore the impact of privacy disclosures on online shoppers’ trust in an e-tailer through a two-phase study. In the first study, we use a between-subjects factorial design to test whether the presence of an online privacy policy influences consumer trust and find that consumers are likely to respond more favorably to a shopping site with a clearly stated privacy message than to one without it, especially when privacy risk is high. In our second experiment, we examine the effects of different forms of privacy disclosures. The results suggest that online shoppers find a short, straightforward privacy statement more comprehensible than a lengthy, legalistic one. However, how a privacy policy is presented (in terms of wording) does not affect a shopper's trust in the store to any significant degree.
