Proportional structural effects of formative indicators

Formative constructs must influence two or more distinct outcome variables for meaningful tests of the formative conceptualization. Because the construct mediates the effects of its indicators, the indicators must have effects on the outcomes that are proportional to their effects on the formative construct itself. This constraint has important implications for developing and testing formative models. This study demonstrates the existence of the constraint, shows that researchers must consider proportionality as a criterion for evaluating the formative conceptualization, provides examples of indicators having different effects and interpretations depending on the outcome variables used, discusses the selection of outcomes to provide rigorous rather than trivial tests of the formative conceptualization, and contends that the formative nature of constructs cannot be justified in isolation from the consideration of outcome variables. In addition, the study demonstrates the importance of considering how the scaling of the formative construct influences the significance of the effects in the model.     

Formative versus reflective measurement models: Two applications of formative measurement

This paper presents a framework that helps researchers to design and validate both formative and reflective measurement models. The framework draws from the existing literature and includes both theoretical and empirical considerations. Two important examples, one from international business and one from marketing, illustrate the use of the framework. Both examples concern constructs that are fundamental to theory-building in these disciplines, and constructs that most scholars measure reflectively. In contrast, applying the framework suggests that a formative measurement model may be more appropriate. These results reinforce the need for all researchers to justify, both theoretically and empirically, their choice of measurement model. Use of an incorrect measurement model undermines the content validity of constructs, misrepresents the structural relationships between them, and ultimately lowers the usefulness of management theories for business researchers and practitioners. The main contribution of this paper is to question the unthinking assumption of reflective measurement seen in much of the business literature.     

Questions about formative measurement

A growing body of literature addresses the issue of formative measurement. However, questions remain regarding the nature of formative measures, their properties, and their usefulness, especially in the context of theory testing and structural equations modeling. This paper poses an incomplete list of questions and suggests possible answers to them, and concludes that the use of formative measurement remains problematic in theory testing research.     

Comment on “Improper use of endogenous formative variables”

Cadogan and Lee's point can be made simpler by referring to the basic math underlying these relationships. The larger problem with this paper, as with the bulk of the formative measurement literature, is a failure of imagination, which is holding back progress in a variety of fields.     

Customer equity management as formative second-order construct

Despite intensive discussions about customer equity, little research addresses how to manage customer equity from a firm's perspective. Recent literature proposes various concepts of customer equity management but does not feature an empirical study that identifies and quantifies activities that aim explicitly to maximize customer equity. In the current study, the authors develop a formative measurement instrument for customer equity management as a second-order construct that indicates how intensively firms orient their customer management toward customer value and equity. The study presents a complete process for conceptualizing and operationalizing a formative second-order construct, including a thorough literature review, intensive qualitative research, and a quantitative study with 92 customer equity managers. On the basis of this process, the authors model customer equity management as a function of three formative dimensions - customer equity analysis, customer equity strategy, and customer equity actions - measured by several formative indicators. The resulting formative operationalization satisfies the criteria for evaluating formative indexes.     

Reflective and formative metrics of relationship value: Response to Baxter's commentary essay

This article responds to some of the issues Baxter [Baxter R., Reflective and formative metrics of relationship value: a commentary essay. Journal of Business Research; 62: 2009.] raises in his recent commentary essay on the special issue of Journal of Business Research (61/12”) on formative indicators. This response shows that poor construct definitions underlie the apparent formative versus reflective controversy and that sound model specifications rest on sound conceptual definitions of the focal construct.     

Reflective and formative metrics of relationship value: A commentary essay

The Journal of Business Research special issue (61/12) covers controversy about formative versus reflective model specification. This essay comments on that special issue and illustrates specific points relating to the controversy by discussing recent studies of business-to-business relationship value, comparing their differing specifications, and noting that the variations of specification result from quite distinct conceptualizations. The essay makes the more substantive conclusion that the differences in conceptualization result from more than one underlying streams of research and that each stream is conceptually quite distinct and needs to follow its own direction for future research. The specific case of relationship value illustrates the broad necessity for researchers to consider in-depth how they conceptualize models. Other research areas have distinct research streams that lie behind different conceptualizations and specifications that researchers must nurture explicitly if useful ontology is to develop effectively.     

Service value revisited: Specifying a higher-order, formative measure

Recent marketing literature pays particular attention to customer value because of the potential impact on customer behavior and, ultimately, firm performance. Whereas some studies conceptualize customer value in a unidimensional manner, more recent approaches take a multidimensional approach, generally conceptualizing value as composed of various benefits and sacrifices. However, nearly all of these studies consider value components in a reflective manner, which is not only problematic but in many cases conceptually incorrect. In addition, recent customer value research includes service components to define and operationalize the construct. This study suggests that customer value in service contexts, or service value, represents a higher-order, formative construct with benefit and sacrifice components. Specifically, the authors propose a formative model of service value with four components: service quality, service equity, confidence benefits, and perceived sacrifice. A multiple-industry study substantiates the contention that this higher-order, formative approach best models value. The results theoretically and empirically support the conceptualization of service value with formative components, and the measure is robust and works well across multiple service contexts.     

The quality of market-oriented behaviors: Formative index construction

Current measures of market orientation do not systematically capture the quality of market-oriented behaviors [MOBs] (Jaworski BJ, Kohli AK. Market orientation: review, refinement, roadmap. Journal of Market Focused Management 1996;1[2]:119-135). In a bid to address this issue, the authors develop formative indices of the key factors underlying market-oriented behavior quality, and empirically validate the indices using survey data from a sample of 253 marketing managers. Findings suggest that optimal market-oriented behavior involves many distinct activities, such as speed and formalization of information generation, dissemination and response, quantity of information generated, comprehensive information dissemination, and extent of information use, to name a few. For researchers, the findings expand the platform from which to generate fresh understanding of MOBs' antecedents and consequences. The indices also have diagnostic capabilities which can help managers understand how to improve the quality of market orientation within the firm.     

Definition and psychometric validation of a measurement index common to website and store images

To mesh together their channels and better handle their multichannel management, retailers must better evaluate and coordinate their various channels. They need more precise and more complete measurement instruments to compare the channels in terms of characteristics perceived by their customers. Using the procedure specific to formative variables, this research results in a particularly comprehensive measurement index that culls 10 channel image dimensions (offering, price, layout, accessibility, promotions, customer service, advice, reputation, institution, connections with other channels) from the 40 strictly identical items for the website and the stores. Various qualitative and quantitative surveys examine across several samples of customers of a major French multichannel retailer, including one sample of 1,478 respondents. This study delineates the scope of website and store images and defines reliable scales for evaluating each image dimension of the channels, including those totally missing from the literature. This measurement tool harnesses website and store characteristics that are very operational and easily actionable. This study demonstrates that a website can be described and analyzed along the same lines as a store, and shows the relevance of incorporating connections with other channels, particularly into the scope of website image.     

Hierarchical Bayesian conjoint models incorporating measurement uncertainty

The authors explore situations where consumers supplement their judgments with a measurement of uncertainty about their own preferences, either implicitly or explicitly, and develop two sets of hierarchical Bayesian conjoint models incorporating such measurements. The first set of models uses the relative location of a rating to determine the importance or weight given to the rating, in a regression setting. The second set uses interval judgment as a dependent variable in a regression setting. After specifying the models, the authors perform a theoretical comparison with a basic Bayesian regression model. They show that, under different conditions, the proposed models will yield more precise individual-level partworth estimates. Two simulated data examples and data from a conjoint study are used to illustrate the gains that could be obtained from modeling uncertainty. In the empirical application, the authors show that model fit improves when ratings for items that respondents do not like are given more weight compared to ratings for items that they do like.

A PLS-SEM approach to understanding E-SQ,E-Satisfaction and E-Loyalty for fashion E-Retailers in Spain

Brand related goals in the online environment are consistent with those of the retail environment: providing products and services that ultimately convert customers into brand loyal customers. Investigating the components of e-loyalty may be a way to improve it. Using a Spanish sample, this study investigates a nine-dimension, latent variable model to understand the relationship between electronic service quality (e-SQ) and e-satisfaction, as well as that between e-satisfaction and e-loyalty within Spanish fashion brand e-retailers. Results suggest that for fashion e-retailers in Spain, e-service quality is positively related to e-satisfaction and e-satisfaction is positively related to e-loyalty. This work supports the use of this framework in future research to better understand these relationships in other countries.

Deriving performance indicators from models of multipurpose shopping behavior

Multinomial logit models have been widely used for predicting and analyzing spatial shopping behavior of consumers. The models typically used in applied settings do not account for impacts of multipurpose shopping behavior on retail system performance. This study focuses on a recent multipurpose shopping model that has favorable properties for use in applied settings. The purpose of the study is to derive indicators of center performance and travel demands from this model. An application shows how the multipurpose model can be estimated based on survey data and which information can be derived from it. Comparison with a conventional single-purpose shopping model indicates that spatial agglomeration impacts as predicted by the model can have substantial meaning for retail impact studies. Therefore, it is concluded that the more complicated models have the potential of improving information in retail planning and analysis.     

An examination of measurement context effects in empirically based advertising research

The purpose of this research was to examine the issue of measurement context effects in advertising processing research. Based upon a review of the advertising processing literature and recent research focusingon measurement contexteffects, hypotheses were specified and empirically tested via a measurement context experiment. The results indicate that the cognitions measurement treatment procedures used in advertisement processing model tests produce small measurement context effects. However, these effects are not sufficiently severe to suggest a reinterpretation of previous findings or to result in drastic changes in future advertisement processing research methods. The results suggest the process of measuring respondents' attitudes towards advertisements did not result in statistically significant measurement context effects on the measures of attitudes towards brands or purchase intentions.

Social Media Index Valuation: Impact of Technological,Social, Economic,and Ethical Dimensions

Marketing practitioners have recognized a growing need to measure consumer-generated social media in a standard way since there are numerous social media indicators in use, making intra- and inter-company comparisons difficult. This paper identifies four social media dimensions for measurement and evaluation: technological, social, economic, and ethical; and, subsequently, measures social media. The study makes a contribution to social media literature by using analytic hierarchy process of developing a mathematical model for social media index valuation. The “social media composite index number” will serve as an industry benchmark signifying the organization's share and commitment to social media.     

Corporate investment, financing, and dividend policies in the high-tech industry

The agency theory, transactional cost economics, and traditional strategic management perspectives have provided several key corporate financial policies. However, these policies have generally been discussed and established separately. This study explores the causal structure of corporate financial strategies for the high-tech firms in Taiwan and China. By employing path analysis and directed graphs model, this paper explores the causal relationships among investment, financing, dividend policies, and corporate performance. The results show that the investment expenditures by Taiwan's firms positively affect financial performance and the increased borrowings jeopardize company's profits. However, the financing decisions of China's firms have a positively effect on their capital expenditures. The findings suggest that firms across the Strait adopt different strategies in financial decision environments.     

Unidimensional measurement and structural equation models with latent variables

This article considers various methods for constructing sets of multiple indicators that measures one and only one trait, i.e., unidimensional measurement. The article compares two procedures for constructing unidimensional measures: the modification index and tests designed specifically for assessing unidimensionality. The specific tests were shown to work better than the modification indices.
