    Do labor mobility, and co-worker networks contribute to convergence or divergence between regions? Based on the previous literature, labor mobility contributes to knowledge transfer between firms. Therefore, mobility may contribute to decreasing productivity differences, while limited mobility to sustaining higher differences. The effect of co-worker networks, however, can be twofold in this process. They transmit information about potential jobs, which may enhance mobility of workers, even between regions, and this enhanced mobility may contribute to levelling differences. But if mobility between regions involves movement costs, co-worker networks may concentrate locally that may contribute to persistence of regional differences. In this paper we build an agent-based model of labor mobility across firms and regions with knowledge spillovers that reflects key empirical observations on labor markets. We analyze the impact of network information provided about potential employers in this model and find that it contributes to increasing inter-regional mobility, and subsequently to decreasing regional differences. We also find that density of co-worker networks, and also their regional concentration decrease, if network information is available.

    Social connections that reach distant places are advantageous for individuals and firms by providing access to new skills and knowledge. However, systematic evidence on how firms work up global knowledge access is still missing. In this paper, we analyse how global work connections relate to differences in the skill composition of employees within companies. We gather survey data from 10% of workers in a local industry in Sweden and complement this with digital trace data to map co-worker networks and skill composition. This unique combination of data and features allows us to quantify global connections of employees and measure the degree of skill-similarity and skill-relatedness to co-workers. We find that the workers with extensive local networks typically have related skills to others in the region and to their co-workers. Workers with more global ties typically bring in less related skills to the region. These results provide new insights to the composition of skills within knowledge intensive firms by connecting the geography of networks contacts to the diversity of skills accessible through them.

    Firms and employees can benefit from information diffusion through social connections at other firms. Therefore, co-worker networks observed in collaborative projects or assumed from job co-occurrence have been analyzed in a wide literature ranging from management to economics, and economic geography. Yet, beyond case-studies, the actual information flows are seldom identifiable in these networks and previous focus on firm- or employee benefits was mainly limited to dyadic relations across firms. To address this gap, we simulate co-worker networks within firms from large-scale administrative data, for which we use parameters fitted to information networks that we collected with a survey and from social media profiles. Then, following all individuals through job moves over their career, we establish the dynamic co-worker network across firms of the entire ICT industry in Sweden. Fixed-effect regression models suggest that growth of average income is significantly higher in those firms that have diverse connections but are central to the network as well. We find that large firms benefit more from triadic closure in the co-worker network, stressing the role cohesive relations in sharing complex knowledge. Our results highlight that firm growth is embedded into the eco-system of co-worker networks that facilitate information flows across firms.

    How does technological relatedness influence the portfolio of multi-product firms hit by external shocks? To answer this question, we look at the effect of product-specific demand shocks on product portfolios of Hungarian firms in the 2005-2012 period. We find that production have become more cohesive in terms of technological relatedness if firms were exposed to demand shocks. Evidence suggests that firms in crisis drop or downsize additional products not related to their core product and concentrate resources on related products.

    Previous studies have shown the impact of family, community, and ethnic networks on migration. Our research focuses on the role of social networks in Hungarian internal migration. We examine the factors determining out-migration rate from municipalities, and the factors influencing location choice by analysingmigration volumes on the municipality-municipality level. We measure social network effects by the migration rate of previous years, and by the intensity of user-user connections on the iWiW online social network (representing3.7million users) between two municipalities. The migration volumes and the characteristics of the municipalities are included in the analysis based on administrative data, and the distance between municipalities are indicated by the travel time. We analyselongitudinal data for the2000-2014 period, and cross-sectional models for the year 2014. Based on multilevel and fixed-effect regression models we show that both leaving and choosing municipalities is associated with network effects: the migration of previous years, and also the connections on iWiW social network influence the current migration rate, even after controlling for each other.

    In this study we investigate the creation and persistence of interfirm ties in a large-scale business transaction network. Transaction ties, firms buying or selling products or services can be the outcome of pure business motivations, but the social connections of owners or the geographical location of companies may also influence their development. We build the transaction and the ownership networks of firms in Hungary for 2016 and 2017 from two administrative datasets and identify multi-layer network motifs to predict the creation and persistence of business transactions. We show that direct or indirect relationships in this two-layered network contribute to both the creation and persistence of business transaction ties. We find a positive, but smaller impact of geographic proximity and industrial similarity of firms. For our estimations, we utilize loglinear models and emphasize their efficiency in predicting links in such large networks. We contribute to the literature by illustrating business connection patterns in a nationwide multilayer interfirm network.

    The rise and popularity of online social networks is a recent phenomenon. In this study, we analyze the reasons and mechanisms behind the collapse of an online social network (OSN), iWiW. Significant cascading mechanisms have been identified in the pattern of abandoning the site at its peak of popularity and after. It is of key importance to study who were the key actors that started these cascades and abandoned the site early compared to others in their network. We contrasted explanations based on preserving accumulated social capital vs. building new social capital with motives influenced by innovativeness. On the one hand, those who are well embedded in their existing network have more to lose. On the other hand, people might want to escape from redundancy and indebtedness indicated by a high local clustering coefficient. We find with heterogeneous choice models that lower degree and a high local clustering are associated with early abandonment. The significant effects of age and innovativeness that depend on the life stage of the OSN indicate that mechanisms related to social capital are not the only reasons for the collapse.

    What puts productivity spillovers into effect through worker mobility across firms? Productivity difference between the sending and receiving firms have been found to drive these spillovers; while an alternative explanation suggests that labor flows from foreign-owned companies provide productivity gains for the firm. We argue here that skill-relatedness across firms also matters because industry-specific skills are important for organizational learning and production. Hungarian employee-employer linked panel data from 2003-2011 imply that productivity gap rules out the effect of foreign spillovers. Furthermore, we find that flows from skill-related industries outperform the effect of flows from unrelated industries.

    Adolescent romantic relationships are sources of social influence concerning educational achievement and delinquent behavior. Integrated schooling is known to induce inter-ethnic friendship relations, however, it also creates the opportunity of inter-ethnic dating. Based on contact theory, inter-ethnic personal relationships or long-term exposure decreases ethnic prejudice, thus it is proposed that willingness to date between ethnic groups may also increase. The question arises, whether in the school context exposure is enough for this mechanism to emerge, or personal contact is necessary. It must be also taken into account, that romantic relationships are embedded in status relations within schools. Previous studies on intermarriage and homogamy found a "social exchange" mechanism, that lower status members of majority groups are more likely to choose minority partners. Translated to the adolescent society, it is assumed, that the less popular members of the majority groups are those, who are more willing to form inter-ethnic dating relations. To address the above questions empirically, the first wave of the Hungarian network panel "Wired into Each Other" was analyzed, containing data of 1214 9th grade students in 43 classes of seven secondary schools. Inter-ethnic dating preferences of Roma and non-Roma students were measured by dyadic attribution of physical attractiveness, and nominations of willingness to date. Statistical analysis was carried out using multilevel p2 models. They suggest that mixed groups are not sufficient, but personal contacts are necessary to decrease same ethnicity preferences in dating. An additional tendency is that among majority students, those who are isolated from the friendship networks are the ones who are more willing to date with the minority group.
