We study network activities of entrepreneurs through three phases of establishing a firm in four countries. Entrepreneurs access people in their networks to discuss aspects of establishing and running a business. We find that entrepreneurs build networks that systematically vary by the phase of entrepreneurship, analyzing number of their discussion partners, and the time spent networking. Entrepreneurs talk with more people during the planning than other phases. Family members are present in their networks in all phases, particularly among those who took over an existing firm. However, women use their kin to a larger extent than men, and even more than men when they take over an existing firm. Experienced entrepreneurs have the same networking patterns as novices. Moreover, these networking patterns are the same in all countries. However, there are country differences in size of discussion networks and time spent networking.

We study how social capital induces performance spillover effects in an industry network of entrepreneurs building their own hydroelectric micro-power plants. Most of them are farmers and novices living in rural areas. There is a link between social capital and performance at firm level. By expanding the level of analysis to dyads, we find that entrepreneurs lacking social capital can compensate for this through cohesion with colleagues rich in social capital. Entrepreneurs can also benefit by mimicking the networking patterns of successful colleagues, gaining access to equivalent resources developed in the niche.

Entrepreneurs use their social network to start businesses. According to Burt, low redundancy in the social network promotes entrepreneurial success. In non‐redundant networks the entrepreneurs’ contacts do not know each other and rarely have the same information. Low network redundancy gives entrepreneurs better information and it allows entrepreneurs to combine resources from non‐redundant sources. In contrast, when there is high redundancy the contacts know each other and may provide the same information. However, our study cannot confirm this hypothesis. Using data on 100 entrepreneurs in Norway we find that simple measures such as the number and strength of ties are more important for entrepreneurs than redundancy because many weak and strong ties increase the entrepreneur’s access to resources. We find that much redundancy is beneficial. Entrepreneurs get information and support more easily if they have many ties with redundant relations.

Well-educated and trained Chinese professionals immigrating to Canada face barriers in nding jobs. To understand this wastage of human capital, we see entry to the professions as mediated by frameworks. The social construction of careers in uences the demand for labour. Human capital is a social construct de ned by certi cation procedures in Canada and by the way Canadian employers perceive appropriate matches of jobs and job applicants. Their demand for people with 'Canadian experience' blocks entry into higher-level jobs. The study interviewed thirty-two couples in 1999-2001 using qualitative methods to learn about their experiences nding jobs in Toronto.
