Research Question:Research Question:
What type of networks provide more/better/right social capital?
Intuition: Entrepreneurial
![Page 3: Entrepreneurial Networks and Social Capital of Academic Scientists Ms. Agrita Kiopa, Doctoral Student Dr. Julia Melkers, Associate Professor School of](https://reader035.vdocuments.site/reader035/viewer/2022062321/56649eac5503460f94bb2fe5/html5/thumbnails/3.jpg)
Roots:Social capital literature:
◦ “investment in social relations with expected returns (Lin 2001)
Network literature:◦ Structural holes are source of social capital
(“early” Burt, 1992)◦ The content of social relationships is as
important in instrumental action as structure (Podolny and Baron, 1997)
◦ Right balance of open and close relationships in network (“late” Burt, 2001)
Our Data: Who are those ngnot(s)?

Entrepreneurial networks:Entrepreneurial networks:
Individual networks that are rich in the structural holes (Burt, 1992, 2000, 2004, 2005)
Individual networks that consist of strong ties with individuals outside of ones organization (Higgins and Kram, 2001)

Hypotheses: Hypotheses: Effects of Network PropertiesEffects of Network Properties
H1: Individuals with networks rich with structural holes will mobilize more social capitalNetworks that are rich in the structural holes are source of social capital (Burt, 1992, 2000, 2004, 2005)
H2: Individuals with networks rich with multiplex relationships will mobilize more social capital
Strong ties are source of social capital (Ibarra, 1995, Krackhardt, 1992, Nelson, 1989, Lin et al, 1981, among others)

In other words
H3: Individuals with entrepreneurial networks will mobilize more social capital

Discussion:Discussion:Measure of efficient multiplexity can be
used to understand the entrepreneurial activities of academic scientists;
Different network structures and properties of relationship may be beneficial for mobilization of different resources;
Relationships within the individual research discussion networks differ by position;

Further Steps:Analysis of other types of relationships in our data;Conceptual expansion of entrepreneurial networks:
◦ “right” balance of “open” and “close” relationships (“late” Burt, 2001, Kadushin, 2002);
◦ “right” balance of “open talk network” and “closed collaboration networks”
Operationalization of entrepreneurial network as one that is rich with multiplex relationships outside of respondents university, country
