    A major component of tax administration reform in sub-Saharan Africa for the last 30 years has been the creation of semi-autonomous revenue authorities (SARAs). The effects of their creation on revenue performance have been much debated, although there are only a few quantitative studies. The core argument of this paper is that existing research suggesting diverse and contradictory outcomes has not taken account of trends in revenue performance in the years before the establishment of SARAs. Allowing for this revenue history, our analysis based on 46 countries over the period 1980-2015 provides no robust evidence that SARAs induce an increase in revenue performance. This does not imply that SARAs may not provide benefits for tax collection, but they do not demonstrably increase (or decrease) revenue collected.

    Economic sanctions, and the suspension of budget support in particular, are supposed to pressure target governments to comply with donors’ demands by putting spending commitments at risk. We argue that this is too simplistic since governments have more fiscal levers at their disposal. The case of Burundi illustrates this argument. Following Burundi’s 2015 political crisis, donors imposed economic sanctions on the country and suspended all budget support to the national government. Using monthly data on the government’s fiscal position between 2005 and 2017, we present evidence from a time series analysis showing that aid does not affect spending and that aid shortfalls are instead systematically compensated with domestic borrowing. It appears that the Burundian government has been able to withstand
    the sanctions and to fulfill its spending commitments by substituting domestic debt for aid. Thus, the economic costs of sanctions do not necessarily translate directly into political costs but a re mitigated by the government’s fiscal response.
