Going beyond prior research that has focused on dyadic, party-specific trust, this study investigates the importance of generalized trust, which is not specific to a counterparty and originates from a broader context. We analyze how generalized trust at the regional level affects the extent to which a firm relies on external suppliers and the performance effects of doing so. Furthermore, we assess how these relationships are impacted by an economic downturn. We exploit differences in generalized trust across 145 regions in 12 European countries and use data on more than a million small- and medium-sized enterprises (SMEs) before and during the Great Financial Crisis (from 2008 to 2010). Control variables are selected via a double-selection procedure based on machine learning. We find that firms in high generalized trust regions, compared with those in low generalized trust regions, source more externally (but do not reduce external sourcing less in an economic downturn) and benefit more from external sourcing during an economic downturn.

This study examines the influence of the social network of board interlocks on strategic alliance formation. Our theoretical framework suggests how board interlock ties to other firms can increase or decrease the likelihood of alliance formation, depending on the content of relationships between CEOs (chief executive officers) and outside directors. Results suggest that CEO-board relationships characterized by independent board control reduce the likelihood of alliance formation by prompting distrust between corporate leaders, while CEO-board cooperation in strategic decision making appears to promote alliance formation by enhancing trust. The findings also show how the effects of direct interlock ties are amplified further by third-party network ties.

The business case for acting sustainably is becoming increasingly compelling - reducing our global footprint to sustainable levels is the defining issue of our times and it is one that can only be addressed with the active participation of the private sector. However, persuading well established organizations to act in new ways is never easy. This book is designed to support business leaders and organizational scholars who are grappling with this challenge by pulling together leading edge insights from some of the world's best researchers as to how organizational change in general - and sustainable change in particular - can be most effectively managed. The book begins by laying out the economic case for change, while subsequent chapters describe how leaders at firms such as Du Pont, IBM and Cemex have transformed their organizations, exploring issues such as the role of the senior team and the ways in which firms shift their identities, build innovative cultures and processes, and begin to change the world around them. Business leaders will find the book a source of both powerful examples and immediately actionable ideas, while scholars will be deeply intrigued by the insights that emerge from the cross cutting exploration of one of the toughest challenges our society has ever faced

This study investigates the origins of variation in the structures of interorganizational networks across industries. We combine empirical analyses of existing interorganizational networks in six industries with an agent-based simulation model of network emergence. Using data on technology partnerships from 1983 to 1999 between firms in the automotive, biotechnology and pharmaceuticals, chemicals, microelectronics, new materials, and telecommunications industries, we find that differences in technological dynamism across industries and the concomitant demands for value creation engender variations in firms' collaborative behaviors. On average, firms in technologically dynamic industries pursue more-open ego networks, which fosters access to new and diverse resources that help sustain continuous innovation. In contrast, firms in technologically stable industries on average pursue more-closed ego networks, which fosters reliable collaboration and helps preserve existing resources. We show that because of the observed cross-industry differences in firms' collaborative behaviors, the emergent industry-wide networks take on distinct structural forms. Technologically stable industries feature clan networks, characterized by low network connectedness and rather strong community structures. Technologically dynamic industries feature community networks, characterized by high network connectedness and medium-to-strong community structures. Convention networks, which feature high network connectedness and weak community structures, were not evident among the empirical networks we examined. Taken together, our findings advance an environmental contingency theory of network formation, which proposes a close association between the characteristics of actors' environment and the processes of network formation among actors.

This study investigates the determinants of bridging ties within networks of interconnected firms. Bridging ties are defined as nonredundant connections between firms located in different network communities. We highlight how firms can enter into these relationships because of the incentives and opportunities for action that are embedded in the existing network structure. Specifically, we propose that the dynamics of proximate network structures, which reflect firms' and their partners' direct connections, affect the formation of bridging ties by shaping the value-creation and value-distribution incentives for bridging. We also argue that the evolving global network structure affects firms' propensity to form bridging ties by shaping the structural opportunities for bridging. We test our theory using the network of partnership ties among firms in the global computer industry from 1991 to 2005. We find support for structural incentives and opportunities as influential precursors of bridging ties.

This paper explores the interplay between social structure and economic action by examining some of the evolutionary dynamics of an emergent network that coalesces into a small-world system. The study highlights the small-world system's evolutionary dynamics at both the macro level of the network and the micro level of an individual actor. This dual analytical lens helps establish that, in competitive and information-intensive settings, a small-world system could be a highly dynamic structure that follows an inverted U-shaped evolutionary pattern, wherein an increase in the small-worldliness of the system is followed by its later decline as a result of three factors: (1) the recursive relationship between the evolving social structure and individual actors' formation of bridging ties, which eventually homogenizes the information space and decreases actors' propensity to form bridging ties, creating a globally separated network; (2) self-containment of the small-world network, or increasing homogenization of the social system, which makes the small world less accepting of and less attractive to new actors, thereby limiting formation of bridging ties to outside clusters; and (3) fragmentation of the small-world network, or the small-world system's inability to retain current clusters. The study uses data on interorganizational tie formation in the global computer industry in the period from 1996 to 2005 to test the hypothesized relationships.

"The goal of MANAGEMENT: AN INTEGRATED APPROACH, 2nd Edition, is to prepare students for leadership positions in 21st century companies by addressing the many facets involved in answering one key question: How are leaders successfully managing competitive companies in the 21st century? Today's constantly changing business environment presents challenges and opportunities that are more dynamic and complex than ever before, requiring a clear understanding of the interactive nature of strategy, organizational design, and leadership. MANAGEMENT: AN INTEGRATED APPROACH, written by prominent Harvard management educators Ranjay Gulati, Anthony Mayo, and Nitin Nohria, is the only introductory management text on the market to address this challenge by taking an integrated and holistic approach to management, as opposed to a functional approach, making it more relevant to how today's organizations run. By demonstrating the interconnectivity among the three key pillars of management, students see how decisions impact strategic choices, organizational alignment, and leadership approaches, ultimately leading to the overall performance of the company. MindTap® for Gulati/Mayo/Nohria's MANAGEMENT: AN INTEGRATED APPROACH, has been completely revised and updated to incorporate a suite of new digital resources designed to facilitate and measure student success. This unique approach will develop a sustainable and successful leadership style, better preparing students for higher level courses and making them more marketable upon graduation." --Publisher

Over the last two decades, the sociology of entrepreneurship has exploded as an area of academic inquiry. Most of this research has been focused on understanding the environmental conditions that promote entrepreneurship and processes related to the initial formation of an organization. Despite this surge in activity, many important questions remain open. Only more recently have scholars begun to turn their attention to what happens to organizations, and the people connected to them, as they mature and move through the life cycle of entrepreneurship. These open questions, moreover, connect to many classic themes in the literature on careers, organizational sociology, stratification, and work and occupations. Using a framework that focuses on three phases of the entrepreneurial life cycle—pre-entry, entry, and post-entry—we summarize sociological research on entrepreneurship and highlight opportunities for future research.

We explore how the initial market positioning of entrepreneurial ventures shapes how they professionalize over time, focusing specifically on the development of functional roles. In contrast to existing literature, which presumes a uniform march toward professionalization as ventures scale and complete developmental milestones, we advance a contingent perspective, distinguishing between the development of external interface functions (marketing & sales and customer development) and internal process functions (accounting, human resources, and finance). Specifically, we argue that positioning in an unconventional market space raises demand for external engagement that focuses ventures' attention and resources toward developing external interface roles. At the same time, such unconventional ventures are less apt to elaborate their internal process roles relative to more conventional peers. We test these predictions using a novel longitudinal data set on the internal organizations of 3,748 U.S.-based entrepreneurial ventures. In contrast to common assumptions of convergent professionalization, our theory and findings advance the perspective that ventures pursue divergent professionalization paths based on their initial market positioning as they scale up.
