Assessing between-group differences in information systems research: a comparison of covariance-and component-based SEM

Multigroup or between-group analyses are common in the information systems literature. The ability to detect the presence or absence of between-group differences and accurately estimate the strength of moderating effects is important in studies that attempt to show contingent effects. In the past, IS scholars have used a variety of approaches to examine these effects, with the partial least squares (PLS) pooled significance test for multigroup becoming the most common (e.g., Ahuja and Thatcher 2005; Enns et al. 2003; Zhu et al. 2006). In other areas of social sciences (Epitropaki and Martin 2005) and management (Mayer and Gavin 2005; Song et al. 2005) research, however, there is greater emphasis on the use of covariance-based structural equation modeling multigroup analysis. This paper compares these two methods through Monte Carlo simulation. Our findings demonstrate the conditions under which covariance-based multigroup analysis is more appropriate as well as those under which there either is no difference or the component-based approach is preferable. In particular, we find that when data are normally distributed, with a small sample size and correlated exogenous variables, the component-based approach is more likely to detect differences between-group than is the covariance-based approach. Both approaches will consistently detect differences under conditions of normality with large sample sizes. With non-normally distributed data, neither technique could consistently detect differences across the groups in two of the paths, suggesting that both techniques struggle with the prediction of a highly skewed and kurtotic dependent variable. Both techniques detected the differences in the other paths consistently under conditions of non-normality, with the component-based approach preferable at moderate effect sizes, particularly for smaller samples.

Trust, satisfaction, and online repurchase intention: the moderating role of perceived effectiveness of E-commerce institutional mechanisms

The effects of e-commerce institutional mechanisms on trust and online purchase have traditionally been understood in the initial online purchase context. This study extends this literature by exploring the role of e-commerce institutional mechanisms in the online repurchase context. In doing so, it responds to the emerging call for understanding the institutional context under which customer trust operates in an e-commerce environment. Specifically, this study introduces a key moderator, perceived effectiveness of e-commerce institutional mechanisms (PEEIM), to the relationships between trust, satisfaction, and repurchase intention. Drawing on the theory of organizational trust, and based on a survey of 362 returning online customers, we find that PEEIM negatively moderates the relationship between trust in an online vendor and online customer repurchase intention, as it decreases the importance of trust to promoting repurchase behavior. We also find that PEEIM positively moderates the relationship between customer satisfaction and trust as it enhances the customers reliance on past transaction experience with the vendor to reevaluate trust in the vendor. Consistent with the predictions made in the literature, PEEIM does not directly affect trust or repurchase intention. Academic and practical implications and future research directions are discussed.

Understanding online customer repurchasing intention and the mediating role of trust - an empirical investigation in two developed countries

Although e-commerce adoption and customers’ initial purchasing behavior have been well studied in the literature, repeat purchase intention and its antecedents remain understudied. This study proposes a model to understand the extent to which trust mediates the effects of vendor-specific factors on customers’ intention to repurchase from an online vendor. The model was tested and validated in two different country settings. We found that trust fully mediates the relationships between perceived reputation, perceived capability of order fulfillment, and repurchasing intention, and partially mediates the relationship between perceived website quality and repurchasing intention in both countries. Moreover, multi-group analysis reveals no significant between-country differences of the model with regards to the antecedents and outcomes of trust, except the effect of reputation on trust. Academic and practical implications and future research are discussed.

Socialization in Open Source Software Projects: A Growth Mixture Modeling Approach

The success of open source software (OSS) projects depends heavily on the voluntary participation of a large number of developers. To remain sustainable, it is vital for an OSS project community to maintain a critical mass of core developers. Yet, only a small number of participants (identified here as ‘‘joiners’’) can successfully socialize themselves into the core developer group. Despite the importance of joiners’ socialization behavior, quantitative longitudinal research in this area is lacking. This exploratory study examines joiners’ temporal socialization trajectories and their impacts on joiners’ status progression. Guided by social resource theory and using the growth mixture modeling (GMM) approach to study 133 joiners in 40 OSS projects, the authors found that these joiners differed in both their initial levels and their growth trajectories of socialization and identified four distinct classes of joiner socialization behavior. They also found that these distinct latent classes of joiners varied in their status progression within their communities. The implications for research and practice are correspondingly discussed.

Social Intermediation in Base‐of‐the‐Pyramid Markets

Our study explores the structuring decisions made by intermediaries seeking to alleviate poverty by connecting base‐of‐the‐pyramid markets with more developed markets. Using intermediation theory to ground our study, we collected qualitative data on 29 social intermediation projects located within Latin America, Africa, and Asia. Our findings suggest that ‘socializing’ intermediation theory to more accurately explain and predict structural outcomes across more diverse contexts requires three key modifications: (1) the attenuation of opportunism, which creates an internalizing social force; (2) the accommodation of non‐monetary objectives, which creates an externalizing social force; and (3) the perception of transaction capabilities as tractable, which serves as a guidepost for reconciling these two opposing social forces.

Geographic and Product Diversification in Charitable Organizations

The diversification of firms into new geographic and product markets has received a tremendous amount of attention in the field of management. Charities, on the other hand, have garnered attention among management scholars primarily as social influencers on multinational corporations. However, over the past half-century, charities have become significant diversified entities in and of themselves. At their core, both charitable and for-profit organizations are bundles of routines that struggle to deal with administrative issues related to institutional isomorphism, organizational slack, and resource dependency. However, from a contextual standpoint, one of the primary mechanisms by which the diversification of charities impacts efficiency is the transaction costs associated with seeking out and maintaining external resources from donors in addition to charities’ internal set of capabilities and routines. Using panel data involving 3,616 charities over a five-year period, the authors’ findings suggest that while the main relationship between geographic diversification and efficiency is U shaped in nature, the main relationship between product diversification and efficiency is inverted U shaped. From an interaction perspective, the authors’ results also suggest that while charities that maintain lower levels of product diversification follow a similar U-shaped curve as they increasingly diversify into new regions, this curve is inverted for charities that are engaged in unrelated types of product diversification. Therefore, the study suggests that the extent to which one type of diversification produces positive or negative efficiencies depends significantly on the level of the other type of diversification. Such findings have theoretical implications for both the charitable and for-profit sectors.

Internet Technologies, ECRM Capabilities, and Performance Benefits for SMEs: An Exploratory Study

Research on large firms suggests that dedicated customer relationship management (CRM) software applications play a critical role in creating and sustaining customer relationships. CRM is also of strategic importance to small and medium-sized enterprises (SMEs), but most of them do not employ dedicated CRM software. Instead they use generic Internet-based technologies to manage customer relationships with electronic CRM (eCRM). There has been little research on the extent to which the use of generic Internet technologies contributes to SME performance. The present study fills the gap, building upon the literature on organizational capabilities, marketing, and SMEs to develop a research model with which to explore the relationships between generic Internet technologies, eCRM capabilities, and the resulting performance benefits in the SME context. A survey across 286 SMEs in Ireland finds strong empirical evidence in support of the hypotheses regarding these benefits. The study contributes to managerial decision making by showing how SMEs can use generic Internet technologies to advance their customer relationships and contributes to theory development by conceptualizing eCRM capabilities in an SME context.

The Extensiveness of Corporate Social and Environmental Commitment across Firms over Time

Corporate social commitment (CSC) and corporate environmental commitment (CEC) are often combined under the general rubric of corporate social responsibility. Although the two sets of activities are similar, they are also very different. Both CSC and CEC respond to issues raised by stakeholders, but CEC tends to be more “technical”. This characteristic demands that CEC fit with the organization, which exposes greater economic opportunities than CSC. As a result, we argue that the extent to which these practices are implemented differs across firms over time. We analyze the extensiveness of implementation of CSC and CEC across 266 firms from 1991 to 2003, using latent growth curve modeling and one-way ANOVA. We find that firms moved towards at least a moderate level of CSC over time, but tended to bifurcate in the extent to which they implemented CEC practices, towards either the high or low end of the scale, over time. In this paper, we contribute to the institutional analysis of practice diffusion by examining how the characteristics of different kinds of practices shape the extensiveness of firm adoption patterns. As well, this research also speaks to corporate social responsibility researchers, pointing to the need to sometimes discriminate between social and environmental practices.

The Enabling and Constraining Effects of Social Ties in the Process of Institutional Entrepreneurship

While the past decade has produced a number of insights into the process of institutional change, scholars still lack a comprehensive understanding of the germinal stages of institutional entrepreneurship. More specifically, further knowledge is needed into what factors cause certain individuals to initiate norm-breaking behaviour while others continue to adhere to societal expectations. Prior work seeking to inform this question has focused either on individual-level or environmental-level explanations. Comparatively, we employ a social network perspective as a ‘meso-level’ lens into the space where actors and their environment intersect. Based upon our qualitative findings, we propose that social ties can serve as an important factor in enabling (heterophilic ties) as well as constraining (homophilic ties) institutional change. However, our data also suggest that these network forces are highly dynamic and contingent upon tie frequency, the sequencing of tie contact, and the prevailing social norms in which tie contact takes place.

A Two-Wave Study of Self-Monitoring Personality, Social Network Churn, and In-Degree Centrality in Close Friendship and General Socializing Networks

We examine the role of self-monitoring personality in shaping network change in two important types of social relationships. In a two-wave social network study, we find that individuals with higher levels of self-monitoring derive persistent personality-linked in-degree centrality benefits in the general socializing network but have fading benefits over time in the close friendship network. Simultaneous examination of the formation and dissolution of relationships over time (network churn) reveals that this pattern of network change is shaped by differential reactions of relationship partners to individuals based upon level of self-monitoring in the two network types. Overall, by incorporating the dynamic reactions of relationship partners, the findings contribute to the understanding of the complex relationship between personality and social network development.
