Using a customer-Level marketing strategy to enhance firm performance: A review of theoretical and empirical evidence

It is becoming increasingly apparent from the literature that marketers need to consider customer-level information when they generate a marketing strategy for the firm. In this article, the authors develop a customer-focused framework that uses a marketing strategy with an overall objective of maximized financial performance. This strategy is driven by seven customer-level marketing tactics and shows how actual customer data can be used to generate an actionable marketing strategy leading to optimal levels of profitability, customer equity, and shareholder value. In addition, the authors discuss a successful implementation of this strategy for several business-to-business and business-to-consumer firms and offer insights as to how to customize an implementation strategy for any firm, along with presenting potential challenges a firm may encounter during the implementation process. Several suggestions for future research are offered to explore and harness this newly available evidence. V.

Unlocking the power of marketing: understanding the links between customer mindset metrics,behavior, and profitability

Recent evidence about the central role played by perceptual constructs in driving performance outcomes has produced a renewed interest in studying customer mindset metrics (CMMs; e.g., satisfaction, service quality, and loyalty intentions). However, we still lack a proper understanding of how (i.e., process) and to what extent (i.e., magnitude) these CMMs ultimately translate into profitability at the customer level. In this study, we integrate CMMs into an individual-level framework of customer behavior and profitability and provide a conceptual understanding of the process through which these metrics influence customer profitability. Specifically, we propose three mechanisms through which CMMs affect customer behavior and profitability: behavioral effect, marketing effectiveness effect, and marketing efficiency effect. We empirically test this framework across two distinct contexts, a B2B high-tech firm and a B2C telecommunications firm. The results demonstrate that these unobservable CMMs have a significant and multi-dimensional impact on customer behavior and customer profitability. Furthermore, we compute the increases in customer behavior and customer profitability that each firm can expect due to increases in CMMs to help firms improve resource allocation and make better decisions about how much (and when) to invest in CMMs.     

Relationship marketing of services—growing interest,emerging perspectives

Relationship marketing is an old idea but a new focus now at the forefront of services marketing practice and academic research. The impetus for its development has come from the maturing of services marketing with the emphasis on quality, increased recognition of potential benefits for the firm and the customer, and technological advances. Accelerating interest and active research are extending the concept to incorporate newer, more sophisticated viewpoints. Emerging perspectives explored here include targeting profitable customers, using the strongest possible strategies for customer bonding, marketing to employees and other stakeholders, and building trust as a marketing tool. Although relationship marketing is developing, more research is needed before it reaches maturity. A baker’s dozen of researchable questions suggests some future directions. holds the J. C.

Reflections on gaining competitive advantage through customer value

Summary Woodruff’s detailed discussion of the meaning and measurement of customer value and how companies can use customer value information in designing their strategies makes a major contribution to marketing theory and practice. It provides an insightful synthesis of the literature on customer value and points out why and how current theory on the subject should be strengthened. It also offers suggestions for companies to foster customer value learning and incorporate it as a cornerstone of their competitive strategies. The primary objectives of my commentary have been (1) to critically examine Woodruff’s contributions and highlight unresolved issues requiring further investigation and (2) extend Woodruff’s contributions by proposing and discussing a detailed framework for monitoring and leveraging customer value. In addressing these objectives, I have attempted to raise questions and offer suggestions—some of which are necessarily tentative—in the hope that they will stimulate additional interest, debate, and research on the topic.

Strategic fit to resources versus NPD execution proficiencies: what are their roles in determining success?

This research examines the roles of strategic ‘fit’ versus execution proficiency in creating superior performance for new products. Specifically, we compare main effects versus moderation effects models of execution proficiency within a resource-based view (RBV) framework. Four new product success dimensions are outcomes. Marketing ‘fit’ and technological ‘fit’ are viewed as resource fit advantages and are antecedents in the model; marketing versus technical execution proficiencies relate to the project’s execution. The results show that the proficiencies-as-moderators model is the better fitting one; marketing but not technical proficiency is the key moderator. The results regarding resource fit advantage show that (1) both marketing fit and technological fit were positively related directly to profitability and to new product advantage; (2) marketing fit had direct positive effects on customer need met; and (3) neither marketing fit nor technological fit predicted speed. Concerning execution proficiencies: (1) technical execution proficiencies led to higher profitability and customer needs met, as well as speed; and (2) marketing execution proficiency was the only construct that led directly to increased success on all four dimensions examined in this research. Overall, support was found for the general premise that both marketing and technological resource fit advantages and marketing and technical execution proficiencies are significant predictors of new product success factors, with marketing proficiencies having additional moderating effects on the relationship of resource fit to performance.

Cause marketing and customer profitability

This research marks the first attempt to investigate the cause marketing–customer profitability relationship, and to assess whether features can moderate the influence of cause marketing (CM) on customer profitability for a focal brand and its main rival. We obtain a panel dataset on 7257 customers to evaluate the Yoplait–Susan G. Komen partnership. On a propensity score matched sample, we estimate a multilevel model and find that Yoplait’s CM initiative positively influences Yoplait’s customer profitability (2.70%), along with a deleterious effect on Dannon’s customer profitability (?13.31%). These findings are theoretically meaningful and pragmatically useful as they: (1) provide behavioral evidence of CM’s profit impact, (2) establish CM as an “offensive” strategy that cultivates the rival’s customers, (3) suggest features can amplify the effect of CM on the focal brand’s customer profitability, and (4) support that managers can add CM to their strategic marketing arsenal as an instrument to strengthen brand equity.

The theoretical underpinnings of customer asset management: A framework and propositions for future research

Most research in customer asset management has focused on specific aspects of the value of the customer to the company. The purpose of this article is to propose an integrated framework, called CUSAMS (customer asset management of services), that enables service organizations (1) to make a comprehensive assessment of the value of their customer assets and (2) to understand the influence of marketing instruments on them. The foundation of the CUSAMS framework is a careful specification of key customer behaviors that reflect the length, depth, and breadth of the customer-service organization relationship: duration, usage, and cross-buying. This framework is the starting point for a set of propositions regarding how marketing instruments influence customer behavior within the relationship, thereby influencing the value of the customer asset. The framework and propositions provide the impetus for a research agenda that identifies critical issues in customer asset management. Ruth N.

Incentivizing CEOs to build customer- and employee-firm relations for higher customer satisfaction and firm value

This research reveals customer- and employee-firm relations to be two routes by which firms can leverage executive incentive structures to create customer and firm value. Analyses of a unique dataset with multiple archival sources show that (1) increases in the proportion of CEOs?? long-term equity-based compensation positively influence actions that build customer- and employee-firm relations as measured by the Kinder, Lydenberg, Domini & Co. (KLD) data source, (2) such effects are stronger in unstable markets, and (3) customer and employee relationship-building actions affect firm value both directly and indirectly via the mediator of customer satisfaction as measured by the American Customer Satisfaction Index (ACSI) data source. The findings have implications for the improvement of customer satisfaction, the role of marketing in the organization, and the design of CEO incentive packages leading to higher customer satisfaction and firm value.     

Furthering the integration of marketing and logistics through customer service in the channel

Recent emphasis on customer service in both the academic and trade literature reveals a growing but confusing body of knowledge. Both the marketing and logistics disciplines have offered varying definitions of customer service, but have failed to offer a comprehensive framework which represents customer service and its related marketing and logistics issues. This article offers the viewpoint that customer service is a conceptual unifying factor for integrating marketing and logistics. The channel system is introduced as the vehicle by which buyer/seller relationships must be analyzed to understand formation of buyer expectations, interaction of marketing and logistics activities, and subsequent customer service performance. The institutional, behavioral, and physical dimensions of channel activity influence many of the marketing and logistics decisions made by management. The framework offered in this article differs from previous efforts in that customer service is the output of the unified activities of marketing and logistics. It considers marketing and logistics decisions jointly, re-evaluates and expands the production function in logistics, and ties customer service to customer satisfaction or dissatisfaction.     

The nature and determinants of customer expectations of service

A conceptual model articulating the nature and determinants of customer expectations of service is proposed and discussed. The model specifies three different types of service expectations: desired service, adequate service, and predicted service.

Customer relationship dynamics: Service quality and customer loyalty in the context of varying levels of customer expertise and switching costs

As customer-organization relationships deepen, consumers increase their expertise in the firm’s product line and industry and develop increased switching costs. This study investigates the effects of customer investment expertise and perceived switching costs on the relationships between technical and functional service quality and customer loyalty. Technical service quality is hypothesized to be a more important determinant of customer loyalty than functional service quality as expertise increases. Both technical and functional service quality are hypothesized to have a reduced relationship with customer loyalty as perceived switching costs increase. Three-way interactions between the main effects of service quality, customer expertise, and perceived switching costs yield additional insight into the change in relative importance of technical and functional service quality in customers’ decision to be loyal. Six of eight hypotheses receive support. Implications are discussed for customer relationship management over the relationship life cycle. Simon J.

Service quality, profitability, and the economic worth of customers: What we know and what we need to learn

In the past, expenditures on quality have not been explicitly linked to profits because costs and savings were the only variables on which information was available. More recently, evidence about the profit consequences of service quality stemming from other sources has been found. This article synthesizes recent evidence and identifies relationships between service quality and profits that have been and need to be examined. The article views the literature in six categories: (1) direct effects of service quality on profits; (2) offensive effects; (3) defensive effects; (4) the link between perceived service quality and purchase intentions; (5) customer and segment profitability; and (6) key service drivers of service quality, customer retention, and profitability. In each category, the author identifies what is known and then suggests an agenda of relationships needing validation and questions needing answers. The article is organized around a conceptual framework linking the six topics. Valarie A.

Research traditions and patterns in marketing scholarship

Summary In the past 40 years, marketing scholarship has made tremendous advances. Our methods are diverse and relatively sophisticated. As a brief perusal of any marketing textbook (or journal) indicates, we have developed approaches for solving important managerial problems. Consumer behavior, sales management, and advertising have been distinct fields of study, within marketing, for more than 40 years. There are specialized journals for each of these areas, butJAMS, as a general journal, also publishes scholarly articles in these areas. Nonetheless, each of these subdisciplines has its own unique set of patterns and traditions, and there does not appear to be a lot of communication between scholars who specialize in distinct subareas. In this way, we have a tendency to remain somewhat isolated as researchers and scholars. At the same time, there is an increasing challenge to fit all of marketing scholarship under one unified and harmonious tent.     

Factors influencing the likelihood of customer defection: The role of consumer knowledge

Customer satisfaction is the predominant metric firms use for detecting and managing customers' likelihood to defect. But while satisfaction and defection are related, satisfaction is only a weak predictor of whether a customer will defect. This article suggests that for repurchase decisions that involve an information-based evaluation of alternatives to the incumbent, likelihood of defection will be influenced by “how much” customers know about those alternatives. The relationship between level of knowledge about alternatives and defection is examined in the context of actual health insurance choices. Results suggest that the level of objective and subjective knowledge about alternatives has a direct effect on likelihood of defection—above and beyond satisfaction level. The view of defection forwarded in this article suggests that managers may be able to gain additional control over customer defection through actions aimed at influencing how much customers know (or come to know) about alternative vendors.

The impact of social influence and role expectations on shopping center patronage intentions

Shopping is generally a socially visible behavior, frequently done while accompanied by friends or family. The importance of the social interaction achieved through shopping would suggest that social referents may affect the patronage behavior of consumers. However, the ability of social referents to influence patronage may depend on how important the role of shopper is to the individual. Historically, females were expected to assume the role of shopper. But there is evidence that currently the role of shopper has increased in importance for males while decreasing for females who do not occupy the role of housewives. This study used a behavioral intentions modeling approach to investigate the strength and significance of social referent influence on three shopper segments with differing types of role expectations. The shopping orientations and retail feature preferences of the three segments were also measured. The findings suggest there are important differences among the three groups.

Exploring the implications of the internet for consumer marketing

Past commentaries on the potential impact of the Internet on consumer marketing have typically failed to acknowledge that consumer markets are heterogeneous and complex and that the Internet is but one possible distribution, transaction, and communication channel in a world dominated by conventional retailing channels. This failure has led to excessively broad predictions regarding the effect of the Internet on the structure and performance of product and service markets. The objective of this article is to provide a framework for understanding possible impacts of the Internet on marketing to consumers. This is done by analyzing channel intermediary functions that can be performed on the Internet, suggesting classification schemes that clarify the potential impact of the Internet across different products and services, positioning the Internet against conventional retailing channels, and identifying similarities and differences that exist between them. The article concludes with a series of questions designed to stimulate the development of theory and strategy in the context of Internet-based marketing. Robert A. Peterson holds the John T.

Toward a theory of customer engagement marketing

Customer engagement marketing—defined as a firm’s deliberate effort to motivate, empower, and measure customer contributions to marketing functions—marks a shift in marketing research and business practice. After defining and differentiating engagement marketing, the authors present a typology of its two primary forms and offer tenets that link specific strategic elements to customer outcomes and thereby firm performance, theorizing that the effectiveness of engagement marketing arises from the establishment of psychological ownership and self-transformation. The authors provide evidence in support of the derived tenets through case illustrations, as well as a quasi-experimental field test of the central tenet of engagement marketing.     

An empirical study of innate consumer innovativeness,personal characteristics,and new-product adoption behavior

This article explores the relationships between innate consumer innovativeness, personal characteristics, and new-product adoption behavior. To do this, the authors analyze cross-sectional data from a household panel using a structural equation modeling approach. They also test for potential moderating effects using a two-stage least square estimation procedure. They find that the personal characteristics of age and income are stronger predictors of new-product ownership in the consumer electronics category than innate consumer innovativeness as a generalized personality trait. The authors also find that personal characteristics neither influence innate consumer innovativeness nor moderate the relationship between innate consumer innovativeness and new-product adoption behavior.
