As the global financial community considers how to extend debt relief accompanied by IMF adjustment programs to vulnerable low-income countries, the issue of policy conditions for fiscal adjustment will inevitably arise. This paper considers the effectiveness of conditions related to domestic revenue mobilization (DRM) in the last systematic round of debt relief in the early 2000s Highly Indebted Poor Countries Initiative and the Multilateral Debt Relief Initiative (HIPC/MDRI). We find that debt relief had no impact on low-income countries’ DRM. Countries benefitting from debt relief had roughly the same DRM as those that did not. And DRM grew only slightly over time for both sets of countries.
