Book essay on Flemming Hansen and Sverre Riis Christensen (2007), Emotions, advertising and consumer choice

Hansen and Christensen discuss a wide range of current issues regarding the role of emotions in consumer behavior as well as measures of advertising effectiveness. The central theme of the book is the elaboration and application of a new tool to measure the emotional constructions that consumers develop for branded fast moving consumer goods. The authors call this measure NERS, which stands for Net Emotional Response Strength. The book appeals to both intermediate and advanced academic readers due to the comprehensiveness of its literature review and the depth of its theoretical developments. The present essay critically comments the contents of the book and then, based on the context provided by the book, discusses in further detail some salient aspects of the role of emotions in consumer choice that deserve special attention. In particular, it is pointed out how some findings from behavioral decision research could improve the conceptualizations offered by Hansen and Christensen.     

Shopping context and consumers’ mental representation of complex shopping trip decision problems

Depending on the shopping context, consumers may develop different mental representations of complex shopping trip decision problems to help them interpret the decision situation that they face and evaluate alternative courses of action. To investigate these mental representations and how they vary across contexts, the authors propose a causal network structure that allows for a formal representation of how context-specific benefits requirements affect consumers’ evaluation of decision alternative attributes. They empirically test hypotheses derived from the framework, using data on consumers’ mental representations of a complex shopping trip decision problem across four shopping contexts that differ in terms of opening hour restrictions and shopping purpose, and find support for the proposed structure and hypotheses.     

Correction Processes in Consumer Choice

Consumers sometimes recognize that irrelevant contextual factors may influence their judgments and decisions. When such factors are detected, consumers might engage in correction processes to counteract unwanted influences in their judgments and decisions. An experiment demonstrated that correction processes can reduce the magnitude of the compromise effect and the attraction effect.     

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.

Interaction effects of mood induction and nominal representation of price on consumer choice

The transition to the euro in several European countries causes consumers to make mistakes in economic transactions. One mistake referred to as the “euro illusion” is the tendency to evaluate prices on the basis of their nominal representation, thus overestimating or underestimating how expensive products are. Investigating effects of the euro illusion on consumer choice as well as moderating effects of mood, three laboratory experiments were conducted employing convenience samples of students. In Experiment 1 a bias toward the nominal representation was demonstrated when participants chose an unfamiliar (fictitious) large-unit currency (small numbers) for paying the price of a consumer product but chose an unfamiliar small-unit currency (large numbers) for obtaining a salary. The bias was larger for participants who were induced to feel positive and deactivated (calm and relaxed) than for participants who were induced to feel negative and activated (anxious and jittery). The difference in frequencies of choice of currency were replicated in Experiment 2. No effects were, however, found of natural mood assessed by self-report ratings. In Experiment 3 choices of more expensive consumer products with additional features were more frequent when the prices were expressed in the large-unit currency than when expressed in the small-unit currency. Neither in this case did self-reported natural mood affect the choices.     

Channels for search and purchase: Does mobile Internet matter?

Recent industry reports indicate that consumers own four digital devices on an average, and switching devices during shopping is the “new normal.” The addition of mobile Internet as a new channel of search and purchase has spurred the adoption of the digital medium, and easy accessibility of the Internet on multiple devices is influencing shopping patterns. A consumer may prefer some channels for search and others for purchase or use a combination of channels to search and purchase simultaneously. As a new channel, it is unclear 1) whether mobile Internet offers greater search or purchase benefits and 2) what type of products are more suitable for mobile Internet search and purchase. In this study, we develop a framework that describes the factors that drive the use of mobile Internet in a multi-channel environment. We test the framework using survey data from a sample of U.S consumers. The main findings from our study indicate that 1) the choice of channel combinations that include mobile relative to other channel combinations increases with an increase in perceived search convenience of mobile channel. 2) in the digital channel, mobile and desktop differ in their utility along search dimensions. The probability of choosing channel combinations that include mobile increases due to search convenience whereas desktop is attractive due to perceived gains of price comparison search; and 3) mobile Internet search increases for consumers searching for utilitarian products. The insights from this study deepen our understanding of how digital media is used in the search-purchase process and have important managerial implications.

Means matter, but variance matter too: Decomposing response latency influences on variance heterogeneity in stated preference experiments

Response time latencies have been shown to influence consumer’s choice behaviour in choice-based-conjoint studies. The literature has shown that response time latencies affect the mean outputs of parameter estimates derived from models of discrete choice. In this paper, we add further insight into the influences response time latencies have on such models by modelling latent response information associated with the variance of random parameter distributions through parameterisation of variance heterogeneity (or heteroskedasticity). We demonstrate that response time latencies influence not only the means of random parameter distributions, but also the variances, and that failure to account for both may result in incorrect model inferences being drawn.     

Product information and consumer choice confidence in multi-item sales promotions

This research augments efforts to produce a richer understanding of the drivers of consumer choice confidence. It examines the interplay between two marketing interventions that consumers encounter in retail marketplaces, diagnostic product information and multi-item sales promotions. Results indicate that the influence of product information varies as a function of sales promotion format. The information effect is weaker when consumers are allowed to select the products that will be included in the promotion. Perception of information adequacy is revealed as a mediator of the information diagnosticity effect. The implications for marketing theory and promotional strategy are discussed.     

A simultaneous model of multiple-discrete choices of variety and quantity

In many categories, consumers purchase discrete quantities of multiple varieties. For example, when doing grocery shopping for cereals, consumers may purchase in each category three units of brand A, four of brand B, and one of brand C. These decisions are often influenced by nonlinear pricing strategies such as quantity discounts. Modeling such multiple-discrete choices is challenging, as they violate assumptions of standard choice models. In this research, the author introduces a computationally attractive choice model that simultaneously captures 1) variety, 2) discrete quantity, and 3) nonlinear pricing strategies, such as quantity discounts. The model assumes that consumers maximize variety of the choice outcome, while taking into account constraints on utilities of alternatives. Application of the proposed model to two datasets demonstrates the superior fit compared to several rival models. Counterfactual analyses demonstrate that the model is a valuable tool for assortment and pricing decisions.     

If we label it, will they care? The effect of GM-ingredient labelling on consumer responses

More than 60% of foods in North American supermarkets contain GM ingredients. While North American consumers seem less concerned about GM foods than Europeans and Japanese, many consumer activists argue that consumers have a “right to know” if what they eat has GM ingredients. Will informative labelling of GM foods lead to major shifts in buying patterns? An experimental study found minimal effects of GM labelling overall but significant differential reactions to GM-labelled products across consumers with differing levels of consumer activism, perceived benefits of genetic engineering, and interest in novel foods with consumer benefits.     

Regional and Categorical Patterns in Consumer Behavior: Revealing Trends

We offer a method of analysis that allows for an “unbundling” of the data to a disaggregate household level, and then “rebundling” it in a manner designed to identify patterns and relationships which are otherwise masked. Applying the method in the context of ‘healthy’ products and using census block group level data, we study consumption over several categories in two locations. The analyses show that studies involving geographically dispersed data must test for, and take into account when required, conceptually sound spatial effects in order to accurately assess impact. We also show that while both location and the product category have a significant impact on the proportion of healthy products purchased, the degree to which consumers choose healthier alternatives is a function of the category as well as the location. Finally, we provide preliminary evidence from survey data that supports the variations we find, and further explores attitudinal differences as well. There are rich implications for retailers in that new products introduced to benefit from popular trends (such as ‘healthy’ alternatives) may not succeed for all categories or locations. Retailers would benefit from understanding the spatial, demographic and attitudinal effects that play into consumption behavior, and such effects can be better understood when studying choice at the category and region level. Finally, public policies aimed at promoting healthier purchasing habits may have greater impact if special attention is given to specific categories and regions.     

On consumer choice patterns and the net impact of feature promotions

Even in the digital age, feature promotions continue to receive significant investments from CPG manufacturers and retailers. Whether this is money well spent depends on consumers' (heterogeneous) tendency to switch brands or stores in response to features. This study proposes a ‘Mixed-pattern Random-effects Nested Logit’ (MRNL) model to analyse the effect of feature promotions in a multi-retailer multi-brand setting. Across 16 different CPG categories, our results reveal that in all cases a mixture of choice patterns prevails: about half of households exhibit a brand focus (i.e. rather substitute between stores offering that brand), the remaining half show evidence of a store focus (i.e. rather substitute brand offers within a visited store). We find that the size of the promotion lift and its underlying sources differ substantially between patterns. Brand-focused consumers are generally more responsive to feature ads than store-focused consumers – especially in low-concentration categories; while they imply much stronger cannibalization for the manufacturer, and much weaker cannibalization for the retailer. It follows that retailers reap much higher benefits in the brand-focused segment, while manufacturers may not prefer that segment in terms of net gains and must be wary of subsidizing those consumers. We identify household and category characteristics that underlie the choice patterns and offer opportunities for targeting.

Search-Purchase (S-P) Strategies of Multi-Channel Consumers

Abstract

Our study sought to determine whether a consumer's search-purchase (S-P) strategy could provide a viable market segmentation tool for understanding consumer's channel choice behavior in today's increasingly complex, multichannel market environment. We collected data (N = 519) nationwide, using a self-administered mail survey and focusing on two product categories (books and apparel). Based on the respondent's search-purchase channel behavior, we identified nine segments and deemed three as viable: the Physical/Physical S-P strategist, the Cross/Cross S-P strategist, and the Cross/Physical S-P strategist. Our findings indicate that a consumer's S-P channel choice strategy is indeed a viable segmentation tool; furthermore, a consumer's S-P channel choice strategy is influenced by the consumer's level of sophistication in regard to the technology and by the benefits sought. We conclude by speculating on the uses that retailers could make of our study, and we propose several possible subjects for future studies.
