Denna studie undersöker användarrecensioners påverkan på konsumenters beslutsprocess vid köp av produkter eller tjänster och faktorer som påverkar förtroendet för dessa recensioner. Studien visar att användarrecensioner har en betydande inverkan på konsumenters köpbeslut, med subjektiva normer och upplevd beteendekontroll som viktiga faktorer i beslutsprocessen. Det finns signifikanta skillnader i preferenser och beteende mellan olika åldersgrupper. Studien bidrar till ökad förståelse för konsumenters beteende och preferenser vid online-shopping och ger vägledning för framtida forskning inom detta område. Företag och e-handelsplattformar kan använda studiens insikter för att förbättra sina produkter, tjänster och marknadsföringsstrategier, genom att ta hänsyn till användarrecensioners betydelse och de faktorer som påverkar konsumenters förtroende för dessa recensioner. / This study examines the impact of user reviews on consumers decision-making process when purchasing products or services and factors that influence trust in these reviews. The study shows that user reviews have a significant influence on consumers purchasing decisions, with subjective norms and perceived behavioral control as important factors in the decision-making process. There are significant differences in preferences and behavior among different age groups. The study contributes to a better understanding of consumer behavior and preferences in online shopping and provides guidance for future research in this area. Companies and e-commerce platforms can use the insights from the study to improve their products, services, and marketing strategies by considering the importance of user reviews and the factors that influence consumers trust in these reviews.

The foundation for this study is based on prior research (Sproles & Sproles, 1990) that determined that learning styles are significantly related to consumer decision-making styles. Decision making involves a process of cognitive learning. Since the study was published, other studies have investigated these consumer decision-making styles. However, no additional studies have further investigated the relationship between learning styles and consumer decision-making styles for college students, especially first-year, first semester college students. Numerous studies have documented that students enter college as consumers but may lack basic knowledge and skills to make consumer decisions and avoid potential debt. The focus of the current study was to determine whether a relationship exists between beginning college students' self-reported mind styles, consumer decision-making styles, and shopping habits. To investigate this relationship, a purposive sample was targeted consisting of first-year, first semester college students. Three instruments were administered: the Gregorc Style Delineator, the Consumer Styles Inventory, and a Demographic Survey. A Chi-Square Test of Independence showed that there is a significant relationship between gender and self-reported shopping habits. Females tend to self-report purchases of clothing more frequently than males. Males tend to self-report purchases of food away from home and gas/auto expenses more frequently than females. No significant relationship was found between students' perception of family income and self-reported shopping habits, suggesting that these students purchase consumer goods frequently regardless of their perceived family income. A Chi-Square Test of Independence also revealed a significant relationship between gender and self-reported, dominant, Gregorc mind styles. Females were more likely than males to self-report their dominant mind styles as Abstract Random. Males were more likely than females to self-report their dominant mind style as Concrete Random. Although the current study's results did not support multiple consumer decision-making styles from previous studies using the Consumer Styles Inventory, an exploratory factor analysis revealed one, overall consumer decision-making style, Recreational/Hedonistic. A Mann-Whitney Rank Sum Test showed that there is a significant relationship between gender and the Recreational/Hedonistic consumer decision-making style. Females tend to be more recreational shoppers than males. A summary, discussion of the results, and recommendations for further research, practice, policy, and families are proposed. / Ph. D.

Historically, consumer perceptions towards dairy products have been measured using a rational cognitive approach. However, recent consumer insights suggest that emotions play a dominant role in consumer decision making. The South African dairy industry therefore identified a need to determine emotive reactions to educational messages in addition to the reasons underpinning dairy consumption. Using a mixed method research approach, reactions from 81 South African dairy consumers were obtained, using three different, but interrelated measuring instruments. Descriptive statistics, hierarchical ladder maps and correlation analyses were used to examine emotive and cognitive consumer reaction to a number of generic dairy messages and products. The findings indicate that certain communication messages appear to have a stronger impact on consumers due to specific emotions that these messages elicit. Personal values underpinning dairy consumption decisions were also identified within the context of emotive reactions to the selected dairy products. / Business Management / M. Com.

Die Dissertation thematisiert die kontextbezogene Präferenzbildung von Konsumenten. Aufsatz 1 untersucht das Substitutionsverhalten von Konsumenten in Out-of-Stock Situationen unter Berücksichtigung des Einflusses von Promotions. Die Ergebnisse zweier Online-Studien zeigen, dass sowohl Phantome als auch Promotions die Dominanzstruktur eines Choicesets verändern und somit zu systematischen Verschiebungen der relativen Präferenzen führen. Aufsatz 2 diskutiert, ob Kontexteffekte in einem hypothetischen Entscheidungsumfeld mit rein imaginären Kaufentscheidungen im Vergleich zu verbindlichen Entscheidungen mit realen Zahlungen systematisch überschätzt werden. Die empirischen Resultate belegen, dass der Ähnlichkeitseffekt in hypothetischen Studien signifikant höher ist als in Erhebungen unter Verwendung von realen Marken und verbindlichen Kaufentscheidungen inklusive tatsächlicher Zahlungsverpflichtungen für die gewählten Produkte. Aufsatz 3 untersucht, ob der „reversed similarity effect“, als die Tendenz von Konsumenten bei der Nichtverfügbarkeit von bevorzugten Produkten solche Substitute zu wählen, die der nichtverfügbaren Wahloption ähnlich sind, auch in realen Entscheidungsgegebenheiten Gültigkeit besitzt und bestätigt dies anhand von zwei empirischen Studien. Aufsatz 4 analysiert den interaktiven Effekt von Phantomen und Händlerempfehlungen auf die Präferenzbildung bei Onlinekäufen. Es zeigt sich, dass der separate Einfluss beider Faktoren nicht zwangsläufig positiv interagiert. Vielmehr bedingen sich Richtung und Stärke der gemeinsamen Wirkung durch die jeweilige Produktkategorie sowie die empfundene Wichtigkeit der enthaltenen Produktattribute. Aufsatz 5 beschäftigt sich mit Präferenzdeterminanten für biologische Produkte. Mithilfe eines Strukturgleichungsmodells kann belegt werden, dass Gesundheits- sowie Umweltmotive keinen direkten Einfluss auf die Bio-Präferenzen eines Haushalts haben, sondern durch die jeweilige Einstellung zu Bioartikeln moderiert werden. / The doctoral dissertation analyzes context-dependent preference formation of customers with regard to the influence of product- and situation-specific as well as experimental factors. Essay 1 studies preference formation of customers in out-of-stock situations by coevally considering the specific influence of promotions. The results of two online studies reveal that both phantoms and promotions induce changes in the dominance structure of a choice set, thereby systematically affecting customers’ substitution decisions. Essay 2 discusses if context effects are significantly overestimated in binding choice settings that include real payments for test products. The attained results confirm that the similarity effect is significantly higher in purely hypothetical decision environments in contrast to realistic choice setting inclusive of payment obligations for the selected products. Essay 3 attends to the question if the reversed similarity effect – as a customers’ tendency to preferably select very similar substitutes when a desired item is temporarily unavailable – also holds true in market-like choice scenarios. The results of a comprehensive online study confirm the existence of the effect in all tested product categories. Essay 4 studies the interactive effect of phantoms, i.e. unavailable choice options, and recommendations on directing customers’ choice in online purchase decisions. It can be demonstrated that the factors’ separate influence does not necessarily add up when appearing within the same choice scenario. Instead boundary conditions of the factors’ interaction are identified. Essay 5 seeks to identify determinants of customers’ preference for organic products. The results of PLS structural equation modelling show that health- as well as environmental motives do not have a direct effect on relative preferences for organic items but that their influence is fully mediated by one’s attitude towards organically produced articles.

Word of mouth (WOM) communication has been a form of additional information for consumers wishing to make a purchase decision where there was uncertainty, lack of knowledge or just a general desire for more information. The increased access and use of social media as well as anonymous opportunities for consumers to provide their reviews on products or services is changing how WOM is used and sought. There is little research on the impact and use of WOM with respect to consumer decision making in a recreation and leisure context. Much research has been focussed on retail experiences and more tangible outcomes. The purpose of this study was to explore the process consumers undertake to seek out, listen and engage in WOM communication when making service purchase decisions. This study took place in a municipality in York Region that offered swimming lessons to the public. Participants were chosen using convenience sampling methodology. 500 surveys were distributed with 301 returned surveys completed to some degree. Study participants were recruited from observers watching a swim class offered by a municipal recreation provider. The survey instrument asked participants to describe themselves in terms of their experience level with municipal recreation programs. It also included three scales relating to susceptibility to influence, self confidence and need for cognition. Participants were exposed to one of five scenarios – one control message contained no treatment information and four scenarios with treatment messages relating to self-confidence and perceived risk. Treatment group members received information suggesting either high and low levels of perceived risk with purchase and high and low levels of self-confidence with knowledge (regarding the purchase decision). Respondents in this study possessed a very high level of self confidence in their program selections; they knew where to find the information and also how to explore program options. Overall this seemed a very well informed and confident group. Results suggest that susceptibility to influence (t = 5.889, p = .000) and self confidence (t = -2.174, p = .037) influenced their search for WOM communication. Need for cognition did not influence the likelihood they would seek WOM communication (t = -1.098, p = .280). Together all three variables explained 50% of the variance (adjusted R2 = .505) in the dependent variable (likelihood they would seek out WOM to make the purchase). These results indicate that participants were more likely to seek WOM when they were susceptible to influence and when their self confidence levels were low. Results also suggest that consumers were open to on line sources of word of mouth communication. More than that, study participants were generally willing to trust online reviews from people who were not necessarily known to them. As a result, online reviews could greatly influence the program registration numbers. A key question for future research could focus on the role shared experience plays in the evolution of trust between strangers. Many of these respondents would trust the advice of others simply because they reported having shared experience. How far does this trust go? How much risk must be present before they hesitate to take advice from unknown individuals? What are the characteristics or traits that consumers look for when assessing the validity of the reviews. Word of mouth seems a very pervasive and resilient concept. This may be particularly important in situations characterized by risk. Additional research could further explore the concept of word of finger and its influence on the traditional concept of WOM communication.

To eliminate this discomfort the consumer may change their purchasing and consumption habits or introduce some measures for the reduction of risk. Since Bauer first introduced the marketing world to the concept, perceived risk has had a long and varied research tradition, yet many authors have failed to recognize in their research how pervasive the construct is in all the stages of the buying process. Hundreds of studies have measured risk perception in wide variety of contexts but, in the vast majority of cases, the stage of decision process in which the consumer found himself/herself in at the time of measurement was not considered. Then, this research brings an innovation in this sense once it considers the whole decision make process in its analysis. Another important contribution of this work is to break with the traditional view of risk reduction models where the risk reduction is mainly linked to the search of information and done on the level of handled risk to consider that risk reduction may happen also with the help of practices and cognitive developments and can be done in two levels: inherent risk and handled risk. Hence, the aim of this work is to understand the way consumers perceive risk in the whole decision making process and to present a typology of risk reduction strategies taking into account the diversity of buying and consumption practices. / Confrontado com o alarmante discurso social que favorece a percepção do risco do alimento à saúde, os consumidores modernos encontram-se em uma situação de desconforto psicológico causada pelo consumo de alimentos que vêm da indústria agrícola e de gêneros alimentícios. Para eliminar este desconforto, o consumidor pode mudar seus hábitos de compra e de consumo ou introduzir algumas medidas para reduzir este risco. Desde que o mundo do marketing foi introduzido a este conceito por Bauer, a teoria de risco percebido teve uma longa e variada tradição na pesquisa, contudo muitos autores não reconheceram em suas pesquisas a dispersão dessa construção em todos os estágios do processo de compra. As centenas de estudos mediram a percepção do risco em uma larga variedade de contextos mas, na grande maioria dos casos, o estágio do processo de decisão de compra, em que o consumidor se encontra inserido em grande medida, não foi considerado. Assim, esta pesquisa traz uma inovação neste sentido, uma vez que considera em sua análise o processo decisório da compra de forma integral. Uma outra contribuição importante deste trabalho está na quebra da visão tradicional dos modelos de redução do risco, onde a redução do risco é ligada principalmente à busca da informação e feita ao nível do risco manipulado, de forma a considerar que a redução do risco pode acontecer também com a ajuda das práticas e de desenvolvimentos cognitivos, podendo ser feita em dois níveis: risco inerente e risco manipulado. Por fim, o objetivo deste trabalho é compreender a maneira pela qual os consumidores percebem o risco, considerando todo o processo decisório, e apresentar uma tipologia das estratégias de redução do risco, identificando a diversidade de práticas de compra e de consumo que fazem parte da escolha do cliente.

However, there are few academic studies dealing with the reasons behind the consumer decision making process among different handsets and mobile calling plans, and how valuable (money-wise) mobile phones features are. This paper casts light on how much consumers accept to pay for mobile phones and calling plan attributes providing hedonic price analyses of Brazilian handset market during 2008. A dataset was compelled on 48 different handsets, from six manufacturer brands and three mobile operators, in nine different mobile plans weekly over the period from January to December, summing up 27 different aspects and 292.410 observations. In addition, Brazilian market is interpreted by Economics of Telecommunications theory, and true price indices are estimated using hedonic techniques and taking into consideration mobile phones features and quality change. / Apesar dos aparelhos celulares terem se tornado parte fundamental da comunicação pessoal durante os últimos dez anos, há escassez de pesquisas de ordem acadêmica dedicadas à valoração das diferentes características dos planos e aparelhos celulares. Vários fatores precisam ser levados em conta para se conhecer a percepção de valor dos atributos dos planos e aparelhos celulares, desde as condições microeconômicas que afetam a evolução do mercado de aparelhos celulares em geral, até as decisões e motivações pessoais do processo de decisão de compra de um consumidor. Este estudo procura responder quais atributos são mais valorizados pelo consumidor brasileiro em um aparelho celular pós-pago, bem como o preço destes atributos no mercado. Para isto aplicou-se o método de preços hedônicos a uma base de dados de 48 modelos de celulares diferentes, de seis marcas presentes no mercado brasileiro, de três operadoras, em nove diferentes planos de assinatura, com observações de preços semanais ao longo do ano de 2008, totalizando 27 atributos diferentes e 292.410 observações. Por fim, também é apresentada nesta dissertação uma interpretação do mercado brasileiro pela ótica da Economia das Telecomunicações, e é realizado o cálculo da deflação ocorrida no mercado brasileiro de aparelhos celulares pós-pagos no ano de 2008 levando-se em consideração as mudanças de qualidade, funcionalidades e características destes aparelhos ocorridas ao longo do ano mencionado.

Abstract Word-of-mouth (WOM) personal referrals are more efficient and influential than other forms of advertising; however, there is a lack of information regarding the value of referral programs. The purpose of this qualitative case study was to explore the perceptions of business owners, staff, and customers of alternative health care organizations in a Midwestern U.S. state about efficient referral strategies, measuring the effect of those strategies, and motivations of consumers to make referrals. Maslow's hierarchy of needs theory of motivation and customer decision-making theories provided the conceptual framework. The research questions addressed how industry leaders perceived and ranked referral strategies and addressed customers' perceptions and motivations to make personal referrals. Data collection consisted of semistructured interviews with 4 business owners, 2 staff members, and 10 client participants. Data were analyzed using constant comparative analysis methods, and member checking enhanced the accuracy of the findings. Results indicated that participants viewed WOM personal referrals as the most efficient nontraditional strategy to make or receive referrals, and they perceived referrals from impartial and trustworthy sources as the most valued information. This research has implications for positive social change. Findings may be used to enhance business owners' understanding of the value of personal referrals in their marketing mix, and of the motivation for customers to make referrals. WOM personal referrals may be used as a marketing strategy to increase sales and lower costs of formal advertising, which may contribute to the growth of the business.
