Determinants of long-term debt issuing decisions: an alternative approach created by Yushu Zhu

This paper proposes a probit model to test capital structure theories. Our model is designed to circumvent a methodological problem in traditional regression analysis stemming from the use of scaling (e.g., in the form of financial ratios) that has plagued capital structure studies for more than 100 years (Pearson, 1897). Without correction, this problem potentially yields a spurious relation between the dependent and explanatory variables. For example, a negative relationship between capital leverage and firm profitability is concluded in the literature, which is counter to what is observed in reality. Using a sample of leverage increasing cases resulting from public debt issuances in US markets between 1996 and 2006, our probit model results indicate that leverage increasing firms tend to be more profitable. Our finding is consistent with the fact that, in practice, more profitable firms usually have easier access to debt markets.
