Results of Robustness Checks Summary Mobilizing more revenue is a priority for sub-Saharan African (SSA) countries. Countries have to finance their development agendas, and weak revenue mobilization is the root cause of fiscal imbalances in several countries. This paper reviews the experience of low-income SSA countries in mobilizing revenue in recent decades, with two broad aims: identify empirical norms of how much and how fast countries have been able to mobilize more revenue and empirical determinants (panel estimates) of revenue mobilization. The paper finds that (i) the frequency distribution of changes in revenue ratios for SSA low-income countries (LICs) peaks at a pace of about 1/2-2 percentage points of GDP in the short-to-medium term and at a pace of about 2-3 1/2 percentage points of GDP over the longer term, and that (ii) almost all SSA-LICs managed to increase revenue ratios by more than 2 percentage points of GDP in the short-to-medium term, at least once in the last two decades. The sustainability of large increases in revenue ratios can be an issue, in particular for fragile countries. The panel estimates suggest that structural factors, such as per capita GDP, share of agriculture in GDP, inflation, degree of openness, and rents received from natural resources, are important determinants of tax revenue Bibliography Includes bibliographical references Subject Revenue -- Africa, Sub-Saharan -- Econometric models Taxation -- Africa, Sub-Saharan -- Econometric models Revenue -- Mozambique -- Econometric models Taxation -- Mozambique -- Econometric models Economic history Revenue -- Econometric models Taxation -- Econometric models SUBJECT Africa, Sub-Saharan -- Economic conditions. http://id.loc.gov/authorities/subjects/sh85001673 Mozambique -- Economic conditions. http://id.loc.gov/authorities/subjects/sh85088184 Subject Sub-Saharan Africa Mozambique Form Electronic book Author Drummond, Paulo Flavio Nacif, 1966- author.
