Abstract: | This paper combines research on the measurement of disclosure quality and the measurement of share price anticipation of earnings to produce a new test of the usefulness of the information disclosed in management discussions of operations and financing for predicting future earnings. Market-Based Accounting Research has shown that earnings changes are anticipated and impounded in prices well before the financial year for which earnings are reported. This price anticipation leads to downward biased earnings response coefficients (ERCs) in the commonly estimated regression model of returns on contemporaneous earnings changes. We exploit predictable differences in the biasedness of the ERC estimate across firm-years to test the hypothesis that share prices are better informed when the annual report contains a detailed discussion of the firm's operations and financing. Our results suggest that such voluntary disclosure may have been useful in predicting future earnings changes. The effect would appear to be strongest (1) in models that examine one-period-ahead and two-period-ahead share price anticipation and (2) when we employ a disclosure index that captures forward-looking information. |
