This paper examines the relationships between taxation and output in C te d’Ivoire during the period 1960-2006. The bounds testing approach to cointegration devised by Pesaran et al. (2001) showed that tax variables, except direct tax, and real GDP are cointegrated and positively related in the long-run. The results of Granger causality tests indicated bidirectional causality between tax revenues and output in the long-run, implying a virtuous circle of tax and GDP. Direct taxes, however, did not cause GDP both in the short and long-run. These findings suggest that i) the tax revenues and, therefore, budget deficit, depend upon the economic activity, and ii) switching the tax burden from direct to indirect taxes is likely to have a positive effect on the economic output.
