Comparative Analysis of Earnings Rate, Retention Rate, and Dividend Yield as Determinants of Capital Growth

This work compares the effect of earnings rate, retention rate, and dividend yield on the capital growth of Nigeria’s emerging and large companies. The study begins with a detailed characterization of emerging companies in the Nigerian context, then, an extensive review of both theoretical and empirical studies surrounding dividend policy. Thereafter, three contextual arguments or positions were identified to provide the framework for divergence or convergence with the outcome of this work. The variables were also specified as follows: growth in equity capital (GEC), earnings rate (ER), retention rate (RR), and dividend yield (DY). Two procedures were adopted: z-test of two means, aimed at providing additional basis for predicting the outcome of our estimates. To do this, ten years time series data were collected from the annual financial reports of ten emerging and twenty large companies quoted on the Nigeria Stock Exchange, thus, pooling 100 data items for emerging companies and 200 data items for large companies. Then, the means of the respective variables for each size of company were compared, particularly, to establish any significant growth pattern explained later i
