Abstract:We use data from the Kauffman Firm Surveys to analyze how the initial capital-structure decision of a U.S. start-up firm affects its subsequent survival and growth prospects. First, we analyze whether start-up capital structure explains whether or not a firm will remain in business after its first three years. We find that a firm using debt in its capital structure, and, in particular, business debt, is significantly more likely to survive. Second, we analyze whether start-up capital structure explains how fast a firm grows during its first three years. We find that a firm using debt, and, in particular, business debt, grows faster. In other words, the initial capital structure decision of a start-up firm does, indeed, matter-in terms of both its survival and growth. We also analyze what factors explain a start-up's decision to use credit, and, conditional upon using credit, its decision as to what type of credit to use-business or personal credit. We find that both firm and owner characteristics explain the use of credit.
