- The model is based upon anempirically testable hypothesis regarding the association between the optimal level of debt and uncertainty arising from macroeconomic or idiosyncratic sources. The model predicts that an increase in either type of uncertainty leads to a decrease in leverage. 1See for example Gilchrist and Himmelberg (1998); Fazzari, Hubbard and Petersen (1988). 2See
