very much depend on individual firm <strong>and</strong> owner characteristics, <strong>and</strong> the nature of the<br />

project being funded. 72<br />

72 We re-iterate that the estimates of financial relationships in Table 14.1 control <strong>for</strong> both observed <strong>and</strong><br />

unobserved differences between firms. This, in effect, r<strong>and</strong>omizes the use of finances allowing us to<br />

uncover the true relationships between the finances themselves. To take a concrete example, firms<br />

with more talented financial managers may be more likely to use both debt <strong>and</strong> equity in their finance<br />

portfolios, whereas less skill-endowed businesses may use neither. If we failed to take these inter-firm<br />

differences into account, our estimates would yield a spurious positive relationship between debt <strong>and</strong><br />

equity finances (this pattern was observed, in practice, <strong>for</strong> results which did not use instrumental<br />

variables). These estimates would, however, only reflect the talent differences between firms <strong>and</strong> not<br />

the true relationships between the finances themselves.<br />
