What is the role of social networks in driving persistent differences between races and genders in education and labor market outcomes? What is the role of homophily in such differences? Why is such homophily seen even if it ends up with negative consequences in terms of labor markets? This chapter discusses social network analysis from the perspective of economics. The chapter is organized around the theme of externalities: the effects that one’s behavior has on others’ welfare. Externalities underlie the interdependencies that make networks interesting to social scientists. This chapter discusses network formation, as well as interactions between people’s behaviors within a given network, and the implications in a variety of settings. Finally, the chapter highlights some empirical challenges inherent in the statistical analysis of network-based data.

In the United States, the duration of children’s preschool attendance differs, with some children attending full-day preschool and some children attending half-day preschool. This difference provides uneven daily exposure to peers that may have implications for childhood social outcomes, including the formation of social networks over time. In this study, we examined the role of full and half day preschool attendance in children’s social network formation. Specifically, using stochastic actor-oriented modeling, we analyzed longitudinal social network data from an intensive observational study of 25 3-year-old and 28 4-year-old students’ social play relationships in two preschool classrooms over the course of an entire school year. Full-day preschool attendance had a negative effect on the formation of children’s social play relationships over time for 3-year-olds but not 4-year-olds. Specifically, 3-year-old children who attended full-day preschool were less likely than their half-day peers to be selected as playmates. We discuss potential developmental and contextual factors that might explain this finding as well as future directions for research.

AbstractDrawing on survey data on individuals’ motives for migration in Sweden (N = 2172), we examine the importance of family and friends for return versus onward migration, including their importance for different age groups and in different communities on the rural–urban spectrum. The results point to a significant relationship between the importance of family and return versus onward migration, with family importance decreasing with age among returning migrants. At the same time, the importance of friends for returning increases with age. The findings did not suggest a significant relationship between urbanicity and returning versus migration elsewhere. Based on a subset of respondents who were employed prior to migrating (n = 1056), we further examined labor market outcomes for onward versus returning migrants. The results broadly indicate that return migrations are linked to lower likelihoods of labor market deterioration and improvement, suggesting greater labor market stability for return vis-à-vis onward migrations. However, the importance of family for returning (versus moving elsewhere) is associated with higher likelihoods of labor market deterioration and improvement compared with staying the same, indicating greater volatility in labor market outcomes when the importance of family is considered.

Social Network Formation

This paper presents a qualitative study of mechanisms enabling social network formation in the R&D unit of a large technology-based organization. Drawing on interviews with 37 high-level technical and administrative unit members, a number of social network enablers could be discerned, which related to the need for effective location mechanisms, special “enrolment spaces”, and mechanisms for forging contacts. It was also possible to identify a number of higher-order factors for facilitation of network formation, namely hierarchical enablers and communicative and assimilative factors. Based on these results, the paper makes suggestions as to the theoretical and practical significance of social network enabling mechanisms in R&D organizations.

This study develops a conceptual framework for applying social networks in usual CRM models. Recent changing in customer relationship theme and putting new media and network-based paradigm into practice makes it imperative to find how social networks affect CRMs. Accordingly, this study explains the role of social networks in customer relationship management by using its analysis, tools and aspects of this concepts based on CRM models. We have provided a SCRM framework that is based on usual CRM models and incorporates Social networks and its tools, methods and analysis. The framework is combination of Social networks concept and traditional CRM concepts.

AbstractBackgroundSocial connections can lead to contagion of healthy behaviors. Successful treatment of patients with opioid use disorder, as well as recovery of their communities from the opioid epidemic, may lay in rebuilding social networks. Strong social networks of support can reinforce the benefits of medication treatments that are the current standard of care and the most effective tool physicians have to fight the opioid epidemic.MethodsWe conducted a systematic review of electronic research databases, specialist journals and grey literature up to August 2020 to identify experimental and observational studies of social network support in patient populations receiving medication for opioid use disorder (MOUD). We place the studies into a conceptual framework of dynamic social networks, examining the role of networks before MOUD treatment is initiated, during the treatment, and in the long-term following the treatment. We analyze the results across three sources of social network support: partner relationships, family, and peer networks. We also consider the impact of negative social connections.ResultsOf 5193 articles screened, 46 studies were identified as meeting inclusion criteria (12 were experimental and 34 were observational). 39 studies indicated that social network support, or lack thereof, had a statistically significant relationship with improved MOUD treatment outcomes. We find the strongest support for the positive impact of family and partner relationships when integrated into treatment attempts. We also identify strong evidence for a negative impact of maintaining contacts with the drug-using network on treatment outcomes.ConclusionsSocial networks significantly shape effectiveness of opioid use disorder treatments. While negative social ties reinforce addiction, positive social support networks can amplify the benefits of medication treatments. Targeted interventions to reconstruct social networks can be designed as a part of medication treatment with their effects evaluated in improving patients’ odds of recovery from opioid use disorder and reversing the rising trend in opioid deaths.

ABSTRACT Objective: To analyze the role of the social network configured by the family/companion and their implications for their stay during the hospitalization of the child in the pediatric hospitalization unit. Method: Qualitative study with ten family members/companions of hospitalized children. Data collection was done through the technique of individual interview, which occurred in the period from February to December 2015. The analysis was thematic, in light of the theoretical reference of "Social Networks" described by Lia Sanicola. Results and discussion: The main role of the social network was emotional and material support, and the main components of this network were: companion, mother, aunt and daughter, as well as nursing team, physician and other family members/companions. Final considerations and implications for the practice: It was verified that the totality of the interviewees was female, however, the husband was the most important member of the social network for the family members involved, since they perform the material/financial and emotional function. In addition, the participants consider that they are responsible for all care to the family and, in the condition in that they are, they understand it as a favor provided by the other members of the network. Identifying the composition of the social networks of family members/companions provides a better targeting of care in order to strengthen the social support received.

Evolutionary Perspectives

During the 1980s and 1990s, feminist evolutionists were instrumental in demonstrating that primate females, including girls and women, can be aggressive and seek status within their groups. Building on their insights, researchers from across disciplines have found that females use a variety of direct and indirect tactics as they pursue their reproductive success. To better understand women’s aggression and status seeking, one also must examine their social networks. Women must not only deal with the dynamics within their groups, they also must deal with pressures from other groups. Success in maintaining connections in one’s social network is vital for access to the various resources women need for their own reproductive success and to keep competitors in check. Overall, women’s social networks, while serving both supportive and competitive functions, profoundly impact on the reproductive future of women and especially the survival and future reproductive strategies of their children.

Underlying Network

Can smart containment policies crowd out private efforts at social distancing? We analyse this question from the perspective of network formation theory. We focus in particular on the role of externalities in social distancing choices. We also look at how these choices are affected by factors such as the agents’ risk perception, the speed of the policy intervention, the structure of the underlying network and the presence of strategic complementarities. We argue that crowding out is a problem when the probability that an outbreak may spread undetected is relatively high (either because testing is too infrequent or because tests are highly inaccurate). This is also the case where the choice of relaxing social distancing generates the largest negative externalities. Simulations on a real-world network suggest that crowding out is more likely to occur when, in the absence of interventions, face-to-face contacts are perceived to carry relatively high risk.
