Impact des infrastructures publiques sur la productivité des entreprises au Sénégal

This paper intends to measure the effects of public infrastructures on firms’ productivity from a sample of 10 subsectors of the Senegalese modern sector. The model used for that purpose is based on the decomposition of the Total Factor Productivity (TFP) growth which includes the contribution of the capital of infrastructures. Innovative econometric techniques such as Fully Modified OLS (FMOLS) are made use of guaranteeing the robustness of estimates. Our findings reveal that public capital significantly contributes to the productivity growth through cost reduction. Moreover, over the period 2000 – 2004, the growth rate of the public infrastructures is considered to be satisfactory since it is located beyond the minimal level required to improve the PTF.
