Investissement public et croissance économique au Cameroun

The present study analyzes the effect of the public investment on the economic growth in Cameroon. It is a question of appreciating the direct effect of the public investment on the growth on the one hand, and of highlighting the indirect effect of this last on the economic growth through private investment in addition. The econometric regression, using a modeling by method ARDL worked out by Pesaran et al. (2001), we end to the following results: (i) the public investment impacts negatively the long-term growth; (ii) no effect of drive of the private investment by the public investment is observed, and (iii) any shock on economic growth observed within a given year is may be entirely integrated within a period of two year.
