AbstractOne of the salient themes, both in the social network analysis literature and its applications to migration research, is a shift to a more dynamic conceptualization of (migrant) social networks. To elaborate on the dynamic nature of migrant networks, I reconstructed and examined the support networks of 134 Filipino nurses, domestic workers, and care workers in New York and London in three migration phases (pre‐migration, initial adjustment, and current situation) through the factors that significantly shaped their stability or evolution at the micro‐ and macro‐levels. At the micro‐level, shifts in the respondents' networks were examined vis‐à‐vis biographical events and transitions. At the macro‐level, immigration policies and migration pathways were also discussed as shaping network dynamics. It was further observed that transnational ties re‐emerged as relevant connections after the initial adjustment phase while ties in intermediary countries and connections that are geographically mobile should be included in an expanded concept of transnational ties beyond the countries of origin and destination.

Previous research on firm performance does not adequately account for the interrelatedness of a firm's professional connections, political ties, and family business-group affiliation. Many widely-cited findings may therefore be subject to confounding bias. To address this problem, we adopt a holistic approach by assembling a new dataset covering professional, political, and family networks for 1,290 large East Asian firms. We find that professional networks buoyed performance during the 2008 financial crisis; political and family networks did not. We provide evidence that information access is a key mechanism underlying the effect of professional networks. A one standard deviation improvement to a firm's professional network position cushioned the fall in quarterly ROA by approximately 35% during the crisis.

Using questionnaire data obtained from a sample of state government managers, our study examines social capital foci (network ties) of mentoring relations. Others have shown that network ties are relevant to career development and advance. We begin with the assumption that enhanced network ties are generally beneficial. We investigate variation in mentorships, which enhance network ties within the focal organization and within organizations external to the focal organization. We examine a number of factors hypothesized as shaping the relationship between mentoring and the development of network ties, including attributes of the protégé and of the mentoring relationship. Our results show that the sex of the protégé and of the mentor does not affect the quantity of network ties conveyed. However, relationships in which protégé and mentor sex is matched provide more network ties. Counter to our expectations, there is no significant difference in the amount and focus of network ties accruing from formal, organizationally sanctioned mentoring and informal mentoring.

Migrant remittances comprise an important capital source for developing countries. Research connects migrants' remittance behavior to altruism, exchange, insurance, and investment motives or to a desire to maintain options available through origin communities. This study provides an alternative "network" perspective: Remittance behavior may depend on the remitting patterns of those in one's social ties—(a) to members of the origin household; (b) to members of "sibling" households, where a member of the ego household has a sibling; and (c) to members of the origin village. We use censuses from 51 villages in Nang Rong, where one in four residents migrated to internal destinations in either 1994 or 2000, and about one in two migrants remitted to their origin households. We observe network effects: Migrants' likelihood of remitting increases with the number of remitters in the household and with the share of remitters in the village, net of village and year fixed effects, and other potential confounders. We link the former pattern to inheritance-seeking behavior in the household, and the latter to shared norms in the village.

This study analyses how domestic companies in Bangladesh emerged as major conglomerates, despite little help from a weak state that could hardly nurture its enterprises. Using a business history approach, this study traces the development of Bangladesh's leading business groups. The history indicates that the entrepreneurial capacity and the creation of close ties with the State were the core factors that helped these business groups survive and grow in an economy led by a state that could do little to promote and offer policies that help in fostering the growth of domestic companies in an emerging economy.

Abstract The interrelations between trade, FDI and migrations have an important impact on the global economy that resulted in the golden age of globalization at first and in a process of slowbalization in the last decade. Against this background, this paper focuses on migrations and FDI and shows that migrant networks encourage cross-border investments. The presence of immigrants is likely to attract new FDI from their country of origin. FDI abroad, furthermore, are positively related to the presence of migrants, thanks to their knowledge of the two markets. We apply a multilevel mixed model to disentangle the hierarchical structure of the data in order to test the relations between FDI and (directional) migration flows. More specifically we test how and to what extent the structure of the international migrants' network contributes to bilateral FDI flows, besides standard models. Results show that migrants' networks exploit the information migrants have on both source and destination markets, and that a more diverse migrants' community in investing countries lowers bilateral FDI.

In recent years the role of social networks and of social capital in shaping migrants' lived experiences and, particularly, their employment opportunity has increasingly come to be recognized. However, very little of this research has adopted a relational understanding of the migrant experience, taking the influence of nonmigrants' own networks on migrants as an important factor in influencing their labour market outcomes. This article critiques the alterity and marginality automatically ascribed to migrants that is implicit in existing ways of thinking about migrant networks. The article draws on oral history interviews with geriatricians who played an important role in the establishment of the discipline during the second half of the 20th century to explore the importance and power of non-migrant networks in influencing migrant labour market opportunities in the UK medical labour market.
