Does Financial Constraint Affect Shareholder Taxes and the Cost of Equity Capital?

We show that firms with the least elastic demand for equity capital should benefit the most from reductions in shareholder taxes. Consistent with this prediction, we find that,  following 1997 and 2003 cuts in U.S. individual shareholder taxes, financially  constrained firms, and particularly those with disproportionate ownership by U.S.  individuals, enjoyed larger reductions in their cost of equity capital than did other firms.  The results are consistent with the incidence of the tax reductions falling mostly on firms  with the most pressing needs for capital. Furthermore, the findings provide an  explanation for the heretofore puzzling finding that, following the unprecedented 2003  reduction in dividend tax rates, non-dividend-paying firms outperformed dividend-paying firms. Not surprisingly, we find that non-dividend-paying firms are more financial  constrained than dividend-paying firms are. When a firm’s financial constraint and dividend choice are jointly considered, we find that the extent of financial constraint  affects the change in the cost of equity capital, but whether a firm issues a dividend does not. In other words, it appears that the extant studies suffered from the omission of a correlated variation, the extent to which a firm is financially constrained.
