Uganda has one of the lowest corporate income tax collection rates in sub-Saharan Africa, while offering generous corporate tax incentives. It is unclear whether tax incentives achieve their objectives without primarily benefiting firms, potentially undermining domestic revenue mobilization and...

We study whether misinvoicing in international trade is reflected in cross-border bank accounts as reported by offshore financial centres. We show that residents hold more offshore wealth when local misinvoicing practices thrive, especially for under-invoiced exports of natural resources. These...

Social protection systems depend mainly on government tax revenue capacity. Raising domestic revenue still represents a...
