With the rising number of women-owned businesses has come a considerable amount of research, and even more speculation, on differences between male and female entrepreneurs and their businesses. To date, these findings and speculations have been largely atheoretical, and little progress has been made in understanding whether such differences are pervasive, let alone why they might exist. Thus public policy-makers have had little guidance on such difficult issues as whether or not unique training and support programs should be designed for women versus men. Moreover, lenders who finance new and growing firms have little to go on but their own ''gut instinct'' in assessing whether women's and men's businesses are likely to run in similar ways, or whether they might be run in different but equally effective ways. The lack of integrative frameworks for understanding the nature and implications of issues related to sex, gender, and entrepreneurship has been a major obstacle. Two perspectives that help to organize and interpret past research, and highlight avenues for future research, are liberal feminism and social feminism. Liberal feminist theory suggests that women are disadvantaged relative to men due to overt discrimination and/or to systemic factors that deprive them of vital resources like business education and experience. Previous studies that have investigated whether or not women are discriminated against by lenders and consultants, and whether or not women actually do have less relevant education and experience, are consistent with a liberal feminist perspective. Those empirical studies that have been conducted provide modest evidence that overt discrimination, or any systematic lack of ''cess to resources that women may experience, impedes their ability to succeed in business.
