Internal cash flows and corporate investment decisions

There continues to be much interest in the impact of internal funds on the level of corporate investment activity. While some studies provide evidence that investment decisions of firms that are financially constrained are more sensitive to the availability of internal funds than those of less constrained firms, other studies show the opposite, i.e. investment decisions of the most credit-worthy firms are most sensitive to internal funds availability. This paper tests these opposing propositions for U.S. firms using data for a longer and more recent period than in prior studies. The results support the latter view, i.e. investments at financially constrained firms are less sensitive to internal cash flows than in financially less constrained firms. Regardless, investments levels are found to be positively related to internal cash flows for all types of firms and for all periods examined indicating a pecking order in financing (firms prefer first using internal funds and only then go to external funds).
