Controlling for other variable known to affect earning growth, such as Return on Asset, Leverage Ratio, Firm Size, Earning Yield, Past Earning Growth and Asset Growth, the empirical result derived from various tool analysis (Correlation method, Simple regression, Multiple regression and Cross sectional regression) concludes that there is a significant positive relationship between dividend payout and future earnings growth of the firm for the next one to three years. In addition, the robustness test shows that the positive relationship between dividend payout ratio and earnings growth hold across from size groups.
