Does Domestic Investment Improve Economic Growth? Evidence From Cameroon

Abstract
The contribution of Domestic investment to economic growth in Cameroon is not clear. This study analyses the effect of domestic investment on economic growth and the nature of the link between the two variables in the same Country. The methodology used in order to analyze the two objectives are the Two Stage Least Square for the first hypothesis and the Granger no causality test recently developed by Toda Yamamoto based on the Vector Auto regressive (VAR) model for the second hypothesis. The results obtained from this analysis indicate firstly that domestic investment does not influence economic growth in Cameroon in one hand and on the other hand, there is no causality between domestic investment and economic growth in the sense of Granger. It is recommended to Cameroon Government to encourage both private and domestic investment. Key words - Domestic investment, Economic Growth, Co-integration, VECM model, VAR model, causality test.JEL classification: F3, F4, C3, E2
