The Fiscal State in Africa: Evidence from a Century of Growth

What is the level of state capacity in developing countries today, and what have been its drivers over the past century? We construct a comprehensive new dataset of tax and revenue collection for 46 African polities from 1900 to 2015. Descriptive analysis shows that many polities in Africa have been characterized by strong growth in fiscal capacity. As a next step, we explain this growth using a fixed-effects long-run panel setting. The results show that canonical state-building factors such as democratic institutions and interstate warfare can increase revenue collection, while government turnover reduces it. Access to external credit and foreign aid are even more important, and both negatively affect fiscal capacity. In addition, access to external revenues, especially from commodity exports and debt, moderates the operation of canonical state-building factors such as democracy and conflict. These insights add important nuances to established theories of state building. Not only are states in Africa more capable than hitherto thought, but the international environment shapes their capacity, both directly and indirectly.
