We study capital structure choices that entrepreneurs make in their firms' initial year of operation, using restricted-access data from the Kauffman Firm Survey. Firms in our data rely heavily on external debt sources, such as bank financing, and less extensively on friends-and-family-based funding sources. Many startups receive debt financed through the personal balance sheets of the entrepreneur, effectively resulting in the entrepreneur holding levered equity claims in their startups. This fact is robust to numerous controls, including credit quality. The reliance on external debt underscores the importance of credit markets for the success of nascent business activity.

Using confidential microdata from the Characteristics of Business Owners survey, we examine why African American–owned businesses lag substantially behind white‐owned businesses in sales, profits, employment, and survival. Black business owners are much less likely than white owners to have had a self‐employed family member owner prior to starting their business and less likely to have worked in that family member’s business. Using a nonlinear decomposition technique, we find that the lack of prior work experience in a family business among black business owners, perhaps by limiting their acquisition of general and specific business human capital, negatively affects black business outcomes.
