    　View Summary

    Abstract

    We examine the effect of private information on the linkage between financial reporting quality and dividends. While prior studies show that better reporting quality mitigates agency problems regarding dividends, this effect can depend on capital suppliers' private information sources. In a sample of Japanese firms, we measure dividend efficiency regarding over‐ and underpayments and use unique main bank relationships as a proxy for private information. Reporting quality enhances dividend efficiency, and this linkage is observed only for firms without main bank relationships. The results suggest that high‐quality reporting streamlines dividends, particularly when capital suppliers do not have private information sources.

    　View Summary

    Abstract

    We examine the impact of the Institutional Shareholder Services (ISS) proxy voting guidelines on managers' opportunistic reporting behaviours. In February 2015, the ISS introduced a new advisory policy based on firms' return on equity (ROE) and started to issue negative recommendations for top executive election in firms whose past average and most recent ROE are lower than 5%. We find that managers are more likely to achieve the 5% ROE after implementing the policy, and they do so by discretionary activities. Our findings imply that accounting‐based guidelines issued by a proxy voting advisor can generate managers' incentives for opportunistic reporting.

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

    Hsihui Chang, Souhei Ishida, Takuma Kochiyama

    Journal of Accounting, Auditing & Finance   39 ( 1 ) 304 - 331  2021.12  [Refereed]

    Authorship：Corresponding author

    　View Summary

    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.
