Business start-ups lack prior history and reputation, face high failure risk, and have highly concentrated ownership. The resulting information and incentive problems, combined with entrepreneurial private benefits of control, affect initial financing decisions. This paper examines simultaneously the impact of these issues on leverage, debt mix and maturity. We find that start-ups with high adverse selection and risk shifting problems contract less bank debt but compensate with other debt sources. Start-ups in growing industries have lower leverage, but raise more bank debt. Entrepreneurs with large private control benefits contract less but longer term bank loans to lower the default probability.
