KCA Journal of Business Management. 1(1) https://www.ajol.info/index.php/kjbm/article/view/438172071-2162https://repository.daystar.ac.ke/handle/123456789/3567This paper adopts the Hendry Model with a two-step method to model a saving function for Kenya. The Model uses a complex dynamic specification that includes lagged dependent and the independent variables. The paper finds that a 1% increase in GDP growth rate leads to a 0.5% increase in private saving in the long run which is consistent with the life cycle hypothesis. A striking result in the saving function is the positive effect that population growth rate seems to have on private savings which puts into question the notion of a smaller population as a mobilization tool for private saving. Even though consumption seems to have a significant negative effect on private savings in the short run, in the long run, it does not seem to have any significant effect. Causality tests support a uni-directional causality from per capita GDP to private saving and a bi-directional causality between Gross Domestic Saving and Investment.enHendry ModelGDP growthKenyaSaving functionGross Domestic SavingInvestmentArticle
