The effect of cash flow on investment: an empirical test of the balance sheet theory

Using a large data set on investments and accounting information for private firms, we put the balance sheet theory to test. We find that firm cash flow has a positive impact on investment and that the effect is enhanced for firms which are more likely to be financially constrained. We also find that the investment-cash flow sensitivity is significantly larger and more persistent during the first half of our sample period, which includes a severe banking crisis and recession. Our results suggest that financial constraints matter more in periods characterized by adverse economic conditions.
