Resolving Group Choice Paradoxes Using Probabilistic and Fuzzy Concepts

The standard assumption of modern social choice theory is that the individuals are endowed with complete and transitive preference relations over the decision alternatives. A large number of incompatibility results has been achieved regarding aggregation of these kinds of preferences. Yet, most voting procedures make no use of this information. Instead they essentially cut down the information provided by the voters. In this paper we deal with some alternatives to the complete and transitive voter preference assumption. Particular attention is paid to imprecise notions: probabilistic and fuzzy preference relations. Rather than establishing new impossibility results, our focus is in resolving various voting paradoxes using imprecise preference concepts.     

Leveraging social media-based determinants to build customer-based brand equity of a retailer

ABSTRACT

Social media is all about consumer networks and consumer relations that challenge marketers to leverage social media as a means to develop and improve their connections with consumers. Though tremendous opportunities via social media are alluring, businesses are still finding it hard to penetrate the clique of consumer interactions that are largely personal in nature. Despite the opportunities available through social media marketing activities, understanding customers and their behavior, and incorporating that information in marketing strategy formulation is critical to successful strategy implementation. This study takes a significant leap forward in this direction. Theoretically grounded in diverse fields, this study demonstrates how retailers can build customer-based brand equity using social media-based brand determinants. Using seemingly unrelated regression technique, this study examines how retailer brands can leverage consumer characteristics on social media to successfully integrate and capitalize on social media marketing activities. This research study has important implications for both marketing theory and practice.     

Intransitive Preferences in Retailing

According to Arrow's well-known ‘parardox of majority voting’, intransitivities can occur in the attempt to establish a social, inter-personal preference ordering. As has been shown by May [1954], for example, a logical equivalent of this paradox can also arise in the case of individual, personal preference orderings. The present paper shows that such cases are quite plausible and natural, in as common a context as the choice of a grocery store. The paper also shows that intransitivities may occur more generally, as a result of decision rules other than the logical equivalent of majority voting.     

I'll have what she's having: (Social) Perceptions of default options and implications for marketing and decision making

The power that default options have in shaping choice has been well established, yet relatively little is known about how decision makers experience and interpret such preselected options. Research suggests that individuals assume defaults represent a recommended course of action, yet the basis for this recommendation is unclear. Across two experimental studies, we explored consumer theories of default recommendations, examining spontaneous and experimentally manipulated perceptions of the basis of the default, and the impact on decision making across different contexts. Evidence across diverse populations and tasks shows that options were retained to a greater extent when represented as the default, consistent with classic default effects. Furthermore, a significant default effect emerged when the decision context was framed as complex. In line with research on social influence, defaults were most effective when they were presumed to reflect the most popular option (regardless of context). Interestingly, participants rated defaults as being more likely to represent the most popular option, regardless of decision context or default explanation provided to them. These findings highlight the importance of understanding the contexts in which default choices are relied upon and how those defaults are perceived by decision makers.     

A Framework for Adopting Collaboration 2.0 Tools for Virtual Group Decision Making

Decision making in virtual teams is gaining momentum due to globalization, mobility of employees, and the need for collective and rapid decision making by members who are in different locations. These factors resulted in a proliferation of virtual team software support tools for decision making, the latest of which is social software (also known as collaboration 2.0), which includes tools such as wikis, blogs, microblogs, discussion forums, and social networking platforms. This paper describes the potential use of collaboration 2.0 software for improving the process and the specific tasks in virtual group decision making. The paper proposes a framework for exploring the fitness between social software and the major activities in the group decision making process and how such tools can be successfully adopted. Specifically, we use a fit-viability model to help assessing whether social software fit a decision task and what organizational factors are important for such tools to be effective. Representative research issues related to the use of such tools are also presented.     

Process and context in choice models

We develop a general framework that extends choice models by including an explicit representation of the process and context of decision making. Process refers to the steps involved in decision making. Context refers to factors affecting the process, focusing in this paper on social networks. The extended choice framework includes more behavioral richness through the explicit representation of the planning process preceding an action and its dynamics and the effects of context (family, friends, and market) on the process leading to a choice, as well as the inclusion of new types of subjective data in choice models. We discuss the key issues involved in applying the extended framework, focusing on richer data requirements, theories, and models, and present three partial demonstrations of the proposed framework. Future research challenges include the development of more comprehensive empirical tests of the extended modeling framework.     

Social media influencers: The formation and effects of affective factors during online interactions

Social media influencers emerged as powerful sources in affecting and guiding consumers' purchase decisions through self-generated content and online interactions with their followers. A large number of studies have so far focused on cognitive aspects such as perceived credibility, trustworthiness, and expertise of these influencers. This study aims to further advance the existing literature on social media influencer marketing from an affective perspective, with a focus on the emotional bonds generated by online interactions between the influencer and their followers. Based on the interpersonal process model of intimacy and theories in celebrity endorsement and social media influencer marketing, it examines the impact of self-disclosure and perceived responsiveness on familiarity and intimacy, which, in turn, affect purchase decision. An online survey was conducted with 304 social media users in Mainland China who have followed social media influencers. The results highlight the formation of two affective factors, namely, familiarity and intimacy, via self-disclosure and perceived responsiveness. Theoretically, this study provides a fresh perspective to better understand the endorser effect outside the regular set of cognitive factors. Marketing practitioners and companies can follow the suggestions of this study to select more effective social media influencers for their marketing campaign, and to build closer relationships with their target customers.     

How do MNCs establish their talent pools? Influences on individuals’ likelihood of being labeled as talent

Addressing the research question of what influences the likelihood of an individual being labeled as ‘talent’ in MNCs, this paper seeks to understand the decision processes involved in the identification of MNC-internal talent. We develop a framework suggesting that the decision to include an employee in a corporate talent pool is a two-stage decision process in which mostly experience-based (on-line) performance appraisal evaluations are used as an input in largely cognition-based (off-line) managerial decision making. Consequently, talent pool inclusion is determined not only by performance appraisal evaluations, but also a number of factors that influence the decision making in the second stage of the talent identification process. Using empirical insights from an in-depth case study as illustrations, we identify three such factors—cultural and institutional distance between the locations of a potential member of the talent pool and the decision makers; homophily between the individual and the decision makers; and the network position of the person in question.     

Consumer brand engagement and its social side on brand-hosted social media: how do they contribute to brand loyalty?

ABSTRACT

Social media offer brands new opportunities to interact with their customers. This paper focuses on consumer brand engagement (CBE) and its social facet in the context of brand-hosted social media. It highlights that CBE (consumer–brand interactions encompassing cognitive, affective and behavioural dimensions) and brand-based consumer–consumer interactions (social brand engagement (SBE)) lead to brand loyalty intentions. Brand customers were surveyed about their favourite brands on Facebook. Results indicate that self-brand connections and SBE are two drivers of CBE, and that CBE is the key element in inducing brand loyalty. In addition, configural analysis shows that high brand loyalty can be achieved through several combinations of social and CBE with various levels of cognitive, affective and behavioural engagement.     

Do family members agree on family purchase decision? – an empirical study among families in Hong Kong

Family decision making is one of the most important consumer decisions. It is complicated because all family members can be involved in the decision‐making process. The current study examined the impact of perceived buying preferences of individual family member on perceived family buying preferences. A new family decision‐making model with family members’ buying preference is proposed based on resources theory, social learning theory and family system theory. It is found that there is a synergy effect in a family decision‐making process. The synergy effect is expressed as positive correlations between individual family members buying preferences. Quota sampling was adopted to collect primary data in Hong Kong using triadic approach. Managerial implications and future research directions are suggested.     

Young Adults and Politics: Investigating Factors Influencing Voter Decision Making

Many parallels have been drawn between politics and marketing; however, the application of consumer behavior decision making to voter decision making is still an important research focus. Results from general elections around the world show that the turnout among young adults tends to be lower than in the general electorate, suggesting low interest and involvement in politics. This qualitative study investigated low-involvement decision making of young adult voters in Australia. Data were compiled from semistructured face-to-face interviews conducted with 29 young adults to explore their views, and NVivo software was used to assist with thematic analysis. Findings suggest that with low-involvement voter decision making, perceived knowledge and passive information seeking are important factors. Exposure to the media also plays an important role, and young voters rely more on traditional media such as newspapers and television than on social media for current political information.     

Global talent management by multinational enterprises post-COVID-19: The role of enterprise social networking and senior leadership

Multinational enterprises' (MNEs') workforce is made up of people from diverse backgrounds and different locations around the globe. The cross-border transfer of knowledge, skills, and best practices among MNE employees is important to maintain global standards and competitiveness. In the post-COVID-19 period, there is a greater need to exchange knowledge in the changing business environment. The purpose of this study is to examine the issues related to MNEs' global talent management, post-COVID-19. The study investigates the use of enterprise social networking applications for better knowledge exchange and tries to understand the moderating role of senior leadership team support in facilitating the usage of enterprise social networks for cross-border collaboration and talent management. After reviewing the literature and relevant theories, we developed a conceptual model, which is then validated using the SEM technique with 347 respondents from 12 MNEs. The study reveals the importance of using enterprise social networks for cross-border knowledge exchange in the post-COVID-19 period.     

Consumer socialization,social structural factors and decision‐making styles: a case study of adolescents in Malaysia

The purpose of this study is to investigate how the process of consumer socialization will determine adolescents’ decision‐making styles. Eight decision‐making styles were conceptualized as outcomes of the socialization process, which is acquired via interaction with socialization agents, namely parents, peers, printed media, television commercials and in‐school education. The study also proposed five social structural variables (social class, gender, ethnicity, residence and religion) as being associated with the socialization agents and decision‐making styles. The study sample consisted of 934 adolescents between the ages of 16 and 19 years. The data were collected using a self‐administered questionnaire and analysed with the SPSS computer program. As a result of regression analyses, significant relationships were found between social structural factors and socialization processes, suggesting that the influence of socialization agents on adolescents may vary according to certain demographic characteristics. Significant relationships were also found between social structural factors and socialization processes. Peers appeared to be the most important agents of consumer socialization, contributing to a variety of desirable as well as undesirable consumer decision styles. Printed media and television commercials were also found to be significant sources of the acquisition of both desirable and undesirable decision‐making styles. Parents and in‐school education, however, were insignificant in the acquisition of any decision‐making styles among adolescents. Information obtained from this study could be useful to government agencies and consumer educators. The most revealing finding of this study is that parents did not contribute to the formulation of decision‐making orientation for adolescents. This points to the need for consumer educators to take steps in designing programmes that will involve parents as primary socialization agents at home; this may be facilitated via printed materials. Apart from this, the information can also be helpful in enabling marketers to be more effective in targeting various adolescent markets by formulating marketing strategies according to demographic factors, socialization process and decision‐making styles.     

The Stability of Judgmental Modelling: an Application in the Social Services

Judgmental modelling has been used on a wide variety of business problems, and with the advent of new technologies is becoming increasingly user friendly. The range of applications has helped develop understanding of managerial decision making processes, especially those related to group decision making. However, to date there has been little evidence of their use in the social services. This paper describes such an application among social workers in the United Kingdom.One of the difficulties facing social workers is deciding how to deal with individuals with mental disorders. The state has various legal procedures which can be brought into operation, ranging from no involvement with the individual through to compulsory hospitalisation. This study shows how a judgmental modelling approach was used to help define the decision variables. A group of experts from a particular social services department worked together on the problem, using a simple computer model to investigate its decision making criteria and the associated processes. The results are fully presented, and the implications for the role of social workers discussed.     

Influence Allocation Methods in Group Decision Support Systems

Influence allocation processes are voting and opinion aggregating methods that allow members to distribute some or all of their decision making influence to others in the group in order to exploit not only the group's knowledge of the alternatives, but its knowledge of itself. Only with the common use of group decision support systems (GDSS) has their use become practical. In this paper we reconsider SPAN, an influence allocation process introduced by MacKinnon (1966a). Experimental comparison shows SPAN to be significantly better at selecting a correct option from a set of options than two common voting methods. An alternative influence allocation process that we call RCON (Rational Consensus), is based on a weighting method proposed by DeGroot (1974) and has been explicated as a normative standard for combining opinion by Lehrer and Wagner (1981). The judgmental inputs to SPAN would appear to be logically related to those for RCON. Submitting the SPAN inputs from the experiment, transformed in this logical way, to the RCON process results in somewhat better performance than with SPAN. However, evidence indicated that the two methods are conceptually and psychologically sufficiently different that an experimental comparison is needed between them.     

Consistency in MCGDM Problems with Intuitionistic Fuzzy Preference Relations Based on an Exponential Score Function

This paper investigates an approach for multiple criteria decision making problems with intuitionistic fuzzy preference relations (IFPRs). An exponential score function for intuitionistic fuzzy numbers is developed. Its novelty is that it can convert an IFPR into a multiplicative preference relation. Then, the exponential score preference relation is introduced and its associated optimal transfer matrix is proposed. The optimal transfer matrix can guarantee the consistency via the additive transitivity property. Furthermore, an optimal model for aggregating group IFPRs to reach consistency is proposed. Finally, a group decision making approach and a multi-criteria decision making approach with IFPRs are presented.     

To post or not to post: social media sharing and sporting event performance

Social networks are becoming increasingly important for consumers, especially in the context of sport, where the service experience is highly intense. Few studies have combined subjective event performance variables and social network variables to analyze social network content sharing by sports practitioners. This article investigates the use of social networks in relation to sporting events. An empirical study examined the role of social network variables and sporting event performance variables in social media use. The sample consisted of 410 triathletes (72.2% male) aged between 18 and 66 years (mean 37.03 ± 8.62). Four analyses were performed using fuzzy‐set qualitative comparative analysis to examine the causes of sharing comments through social media, sharing photos and videos on social media, participant satisfaction, and word‐of‐mouth (WOM). The event's general image was a necessary condition in all cases. The combination of participants’ satisfaction and positive event image and the combination of social network use and positive event image lead to social network content sharing by athletes. The combination of positive event image and participant satisfaction leads to a positive WOM.     

Some Hesitant Fuzzy Aggregation Operators with Their Application in Group Decision Making

Hesitancy is the most common problem in decision making, for which hesitant fuzzy set can be considered as a suitable means allowing several possible degrees for an element to a set. In this paper, we study the aggregation of the hesitancy fuzzy information. Several series of aggregation operators are proposed and the connections of them are discussed. To reflect the correlation of the aggregation arguments, two methods are proposed to determine the aggregation weight vectors. Based on the support degrees among aggregation arguments, the weight vector of decision makers are obtained more objectively. To deal with the correlation of criteria, we apply the Choquet integral to get the weights of criteria. A method is also proposed for group decision making under hesitant fuzzy environment.     

Revisiting the European Horsemeat Scandal: The Role of Power Asymmetry in the Food Supply Chain Crisis

This study explores the role of power asymmetry in the food supply chain, especially in relation to the channel conflict, and ultimate breakdown that culminated in the infamous European horsemeat scandal across Europe. Drawing upon the power‐dependency, and to some extent, social exchange theory, the study posits that mutual dependence between single supplier–multiple buyer relationships where major retailers are the weaker partners, may require a revisitation of risk management practices in that sector. In addition to the fraudulent and unethical practices established from media reporting on the horsemeat scandal, the study argues that the power asymmetry/imbalance may have contributed to a supplier culture that tolerated the unethical decision making leading to the horsemeat scandal. Based on an extensive review of secondary data sources comprising media reports on the scandal and a review of the academic literature on power dependency and social exchange theories, the study attempts to map out the root of the crisis, how to forestall future recurrence, and the managerial and policy implications of these. © 2016 Wiley Periodicals, Inc.     

Consumer input in standardization: a case study of toy safety

Abstract

Ever since the ‘new approach’ to the achievement of the Internal Market was adopted, the importance of European Standardization has increased. The standardization institutes are now responsible for the technical elaboration of requirements touching upon health and safety of consumers. Therefore, it is of major importance for consumer movements to have an input in the process. In this study, the consumer interest articulation in the ‘new approach’ policy-making process is looked into. The role consumer organizations play in both the pre-standardization and the actual standardization stage are dealt with. Toy safety is taken as a case-study, and the information for the research was mainly gathered from interviews with about 30 representatives of European and national consumer movements, government agencies and industry involved in this field

The study shows that the influence of consumers in the pre-standardization stage, when a directive is drafted and a mandate negotiated between the European Commission and the standardization institutes, is limited

As concerns the standardization stage, consumers have representation in technical committees and working groups of the European standardization institutes. The participation of European and national representatives is compared

The main findings of this research are that consumer input in the actual standardization process is crucial, since their input in the pre-standardization phase is limited. In addition to this, the European and the national consumer representatives are not equally successful in assuring consumer input in this particular policy area. The causes for this difference are considered.
