Does reliance on tax revenue build state capacity in sub-Saharan Africa?

Academics and donors have increasingly argued that African states can enhance their general administrative capacity by improving tax revenue collection. Proponents argue that administratively demanding improvements in tax administration may spillover to other areas of public administration by introducing improved practices, necessitating improvements elsewhere and providing data for other government activities. We make the first effort to test this hypothesis empirically, using an improved cross-country data set for sub-Saharan Africa. We find some evidence that from 1973 until the late 1990s improvements in tax administration tended to precede broader administrative improvements, consistent with the research hypothesis. By contrast, we find no evidence of such a pattern over the past decade. We conclude that these results provide tentative support for the hypothesis that improvements in tax collection can be a catalyst for broader gains in state capacity, but that such linkages are not guaranteed and depend on the particular character of reform.
