Reviewing a body of work presents unique opportunities for making a theoretical contribution. Review articles can make readers think theoretically differently about a given field or phenomenon. Yet, review articles that advance theory have been historically under‐represented in Journal of Management Studies. Accordingly, the purpose of this editorial is to propose a multi‐faceted approach for fashioning theoretical contributions in review articles, which we hope will inspire more authors to develop and submit innovative, original, and high‐quality theory‐building review articles. We argue that advancing theory with review articles requires an integrative and generative approach. We propose a non‐exhaustive set of avenues for developing theory with a review article: exposing emerging perspectives, analysing assumptions, clarifying constructs, establishing boundary conditions, testing new theory, theorizing with systems theory, and theorizing with mechanisms. As a journal, Journal of Management Studies is a journal of ideas – new ideas; ideas drawn from reflections on extant theory and ideas with potential to change the way we understand and interpret theory. With this in mind, we think that advancing theory with review articles is an untapped source of new ideas.

In spite of the proliferation of research on cultural differences in international mergers and acquisitions, we lack systematic analyses of the impact of cultural factors on knowledge transfer. In this paper, we argue that both national and organizational cultural differences and cultural integration in the form of cultural convergence and crossvergence affect knowledge transfer in acquisitions. We develop specific hypotheses concerning the nature of these effects, and test our hypotheses with data on international acquisitions carried out by Finnish corporations. The analyses performed show that national cultural differences provide great potential for knowledge transfer in international acquisitions. Furthermore, organizational cultural convergence and crossvergence have a significant positive impact on knowledge transfer. In particular, convergence and crossvergence moderate the impact of national cultural differences on knowledge transfer.

The purpose of this paper is to elucidate the effects of organizational and national cultural differences on international acquisitions. We argue that cultural differences prompt social identity building that leads to ‘us versus them’ thinking and thereby creates the potential for social conflict. We also maintain that the same cultural differences can contribute to learning in terms of knowledge transfer. We develop a structural equation model to test these hypothesized effects on a sample of related international acquisitions. Our analysis shows that cultural differences at the organizational level are positively associated with social conflict, but that national cultural differences can decrease social conflict. Furthermore, both organizational and national cultural differences are positively associated with knowledge transfer. This analysis shows the importance of disentangling the various effects that cultural differences have on international acquisitions. It also suggests that national cultural differences are less of a problem in international acquisitions than is usually assumed.

Sociocultural factors are important determinants of merger and acquisition (M&A) outcomes.Despite advances in this field, our understanding of sociocultural factors in M&As remains incomplete. In particular, the roles of sociocultural interfirm linkages, HR flexibility, and organizational cultural differences in M&As require further elucidation. The present article contributes to the M&A literature by further clarifying the multifaceted role of these sociocultural factors in M&As. We suggest that sociocultural interfirm linkages (complementary employee skills, trust, collective teaching, and cultural integration) between the merging firms influence the level of knowledge transfer in M&As. Furthermore, we argue that HR flexibility (flexibility in employee skills, flexibility in employee behavior, and flexibility in HR practices) is vital for the development of the above-mentioned sociocultural interfirm linkages in M&As. Finally, we maintain that organizational cultural differences are important antecedents of HR flexibility in M&As.

Ambidexterity is a growing field of management research. However, the role of human resources (HR) and organizational factors needs further exploration because of the fragmented nature of prior work and the subsequent lack of a unifying framework. Our review of 41 empirical studies identifies distinct research streams that relate to the effects of employee characteristics, leader characteristics, organizational structure, culture, social relationships, and organizational environment on ambidexterity. We discuss the most important findings within each stream, which contributes to the HR and ambidexterity literature by addressing the current state of our knowledge. To move forward research in this area, we identify important, yet underexplored areas in each stream. This contributes to the literature by highlighting specific gaps in our current knowledge that represent new avenues for future research. We also identify important interrelationships between different streams that need further clarification. We summarize our findings into an integrative model that elucidates the role of HR and organizational factors in ambidexterity. This contributes to a more comprehensive understanding of ambidexterity from the HR and organizational perspectives. © 2015 Wiley Periodicals, Inc.

International audienceDespite decades of research, the key factors for success in mergers and acquisitions (M&As) and the reasons why M&As often fail remain poorly understood. While attempts to explain M&A success and failure have traditionally focused on strategic and financial factors, an emergent field of inquiry has been directed at the sociocultural and human resources issues involved in the integration of acquired or merging firms. This research has sought to explain M&A performance and underperformance in terms of the impact that variables such as cultural fit, management style similarity, the pattern of dominance between merging firms, the acquirer's degree of cultural tolerance, and the social climate surrounding a takeover have on the postmerger integration process. In this article, we attempt to take stock of, and synthesize, the findings from research on sociocultural and human resources integration in M&A, to identify conflicting perspectives and unresolved questions as well as several underresearched areas, and then use our analyses to propose an agenda for the next stage of research in this fiel

The coauthors wish to acknowledge the contribution of the entire X-Culture team: Without the hard work the 141 instructors and thousands of students do every day, the X-Culture Project in general and this study in particular would not be possible. We also would like to acknowledge the support of our many corporate partners, including Gramedia, Lidaris, Innospark, and Caja de Burgos, whose involvement makes the project more meaningful and educational for our students.
