I evaluate the accuracy with which respondents report egocentered network data. I find that 72% of the time ego’s assessment of the tie between a pair of alters corresponded with both alters’ report of the tie between themselves, and 87% of the time, ego’s report of the tie between a pair of alters is in agreement with at least one of the alters. I discuss the implications of the findings for the debate over the merits of egocentered network data.

In this chapter, we focus on the social integration of young immigrants in Sweden who themselves and/or one or both of their parents came from Iran or former Yugoslavia. In particular, we look at the share of alters in their core networks who are of the same parental national origin and how this has changed within a period of four years. To explain network changes, we consider the parental national origin similarity among them, changes in opportunities to meet network members, and important life events.

We analyzed two waves of survey data collected in 2010 and 2014 from 1,537 individuals who live in Sweden and who were all born in 1990, including 325 immigrants from Iran, 447 immigrants from former Yugoslavia, and 805 native Swedes. The results indicate that: (a) the share of parental national origin similar alters in the core networks of immigrants significantly increases over time, (b) first-generation immigrants in particular increasingly associate with others who are of the same parental national origin, (c) important life events hardly result in network changes, and (d) schools and work places are social contexts that enhance the social integration of immigrants, because in these contexts immigrants meet and engage in personal relationships with individuals who do not share their parental national origin.

We argue for a broadened approach to brokerage by distinguishing between brokerage emphasizing a particular structural pattern in which two otherwise disconnected alters are connected through a third party (“brokerage structure”) and the social behavior of third parties (“brokerage process”). We explore a processual view of brokerage by examining three fundamental strategic orientations toward brokerage: conduit, tertius gaudens, and tertius iungens that occur in many different forms and combinations. This processual view is especially relevant in increasingly complex and dynamic environments where brokerage behavior is highly varied, intense, and purposeful, and has theoretical implications for studying multiplexity, heterogeneity, and brokerage intensity.

We construct a theory of team collaboration to explain how social actors activate their network ties to gain access to and acquire the use of social capital held by other network actors. Drawing from weak-strong tie theory and closure-brokerage models of network structures, our theory specifies dynamic processes in which relations vary in their potential for activation, and thus, project teams have differential probabilities of mobilizing and gaining collective use of the varied resources held by their network alters inside and outside the team. The theoretical scope is interorganizational team whose members are employed by two partnering organizations and are assigned to a joint project with a single task or goal to be accomplished within a limited period. We present and discuss a set of propositions about factors that affect the ability of a team to access its members’ social capital for use in a project task.

In a study of conflict in organizations, Lindenberg’s relational signaling theory is used to develop hypotheses on the impact of relationship strength, network embeddedness, and organizational change on social escalation. Social escalation is defined as the involvement of one or more third parties in a conflict. An empirical test is conducted with data on 67 conflicts involving 22 managers, gathered during three years of ethnographic fieldwork and a longitudinal network study in a management team of a German paper factory. Multilevel analysis indicates that strong ties between conflicting parties decrease the level of social escalation, whereas informal power advantage of one party increases the chances for social escalation. Both effects disappear over time. It is argued that the dissolving impact of relationships and networks is due to the disappearance of so-called solidarity frame-stabilizing activities in the firm. The results highlight the context-dependence of network effects and escalation processes.

This chapter discusses the empirical application of a class of strategic network formation models, using the approach to identification introduced by de Paula, Richards-Shubik, and Tamer (2018). The author emphasizes the interplay between model specification and computational complexity, and suggests tactics to make empirically realistic models become tractable. Two detailed examples, on friendship networks and coauthorship networks, are used to illustrate these issues and to demonstrate the performance of the approach with both simulation and empirical evidence. Also, the author presents extensions to the estimation method, which expand the potential range of applications, and which provide statistical inference with minimal computational burden.

To identify, conceptualize, and analyze a newly emerging form of consumer-initiated, brand-altering activity that we term “brand remixing.”

A content analysis of 92 remixes of the Nokia Lumia 820 smartphone case.

We find that nearly 40% of the remixed versions of Nokia’s case retained at least one element of its standard template. The remixed cases contained considerable congruency with the design elements in the standard template, a high degree of personalization, and no negative brand imagery.

Our research is the one of the first examinations of the role of 3D printing upon marketing activities. It has important implications for marketing scholarship by showing that 3D printing empowers consumers to physically alter the brands they consume. Our research also suggests that practitioners interested in using this technology to develop and enhance their brands should accept the notion that firms are no longer fully in control of their brand assets. Hence, we believe that brand managers should develop co-creation platforms that allow customers to easily modify, remix, and share various aspects of their brands with their peers.

We identify and label an important emerging branding practice (i.e., brand remixing). This practice has the potential to dramatically alter the branding landscape.

Organizational networks are generally considered major antecedents of mutual influence in adopting similar practices, typically via a structure of dense ties, or closure. We propose that under conditions of competitive interdependence, closure may be associated with links established to access resources and knowledge and become a possible source of differentiation rather than imitation. We test these and other antecedents of imitative behavior and performance in the Italian TV industry with 12 years of data on 501 productions. We find that network closure is associated with lower imitation, centrality, but not status, leads to imitation, and that imitation lowers performance.

We examine how the ability of one actor to gain access to resources controlled by another depends on two factors: (i) the number of mutual acquaintances connecting the prospective lender and borrower and (ii) the scarcity of the resources in question. We argue that the incentives to renege on an agreement grow as the resources being traded become increasingly scarce. Mutual acquaintances, however, dampen these incentives, and therefore become more important to facilitating exchange as demand for the good of interest rises. Our analysis of qualitative and quantitative evidence from a study of senior partners at an international consultancy supports these propositions.
