In this article, we explore several factors that may have an effect on busi
ness start-ups, focusing on possible gender differences. We conceptualize s
ocial capital as inhering in people's relations with others and examine the
association between men's and women's social capital and their likelihood
of starting a business. Two aspects of respondents' social capital are high
lighted: the extent to which their business discussion networks are heterog
eneous and the extent to which they contain a high proportion of kin. We sh
ow that a high proportion of kin and homogeneity in the network, rather tha
n a high proportion of females in the network or being female, are critical
disadvantages facing potential small business owners.
