Note(s): The dependent variable is the logarithm of the financed amount. Robust standard errors are shown in parentheses. Models from 1 to 3 and from 4 to 6 are tested on the low and high appropriability sectors, respectively. Models 3 and 6 are tested on the sub-sample of companies holding at least one patent. The significance levels are represented by ∗∗∗ as 1%, ∗∗ as 5%, and ∗ as 10%
