An Empirical Test of the Optimal Disclosure Hypothesis
Abstract: According to the cost-of-capital hypothesis, increased
voluntary disclosure should reduce information asymmetries, lower the cost
of capital, and increase firm value. The optimal-disclosure hypothesis,
however, predicts that costs related to voluntary disclosure lead to the
existence of an interior optimum of disclosure that maximizes firm value.
These hypotheses are tested using disclosure indexes based on analysts’
ratings of firms’ financial reports for a sample of 181 Swedish firms. For
annual reports, the data supports the optimal disclosure hypothesis,
whereas for quarterly reports the findings suggest the existence of a
“disclosure premium” in accordance with the cost of capital hypothesis.
