    • Management Forecasting Ability and Predictive Ability of Dividend Changes for Future Earnings Peer-reviewed

      We revisit the predictive ability of dividend changes for firms’ future earnings and extend the literature by examining the effect of management forecasting ability. Although prior studies have examined the relationship between dividend changes and future earnings, the empirical evidence is mixed. The belief that dividend changes have implications for future earnings depends on the assumption that managers can accurately assess future earnings prospects. In this regard, we posit that the predictive ability of dividends can vary with managers’ forecasting ability. Analyzing a large sample of Japanese dividend-paying firms, we find that dividend changes, particularly dividend increases, are positively associated with increases in future earnings. Consistent with our hypothesis, this positive association is more pronounced for firms with high-forecasting ability managers. Our findings support the signaling theory of dividend changes and indicate that management forecasting ability has a moderating effect on the linkage between firms’ dividend changes and future earnings.

      Grant amount:\3640000 ( Direct Cost: \2800000 、 Indirect Cost:\840000 )

      This study empirically analyzed whether earnings forecasts reflect managerial ability and whether earnings forecasts are used in the managerial labor market. Using the Managerial Ability Score (MA Score) devised by Demerjian et al. (2012) as a measure of managerial ability, we found that companies with higher MA Scores release more accurate earnings forecasts and that managers of companies with more accurate earnings forecasts are less likely to be replaced. These findings suggest that earnings forecasts reflect managerial ability and are used by the managerial labor market.
