The International Monetary Fund (IMF) slightly revised upward growth projections for SubSaharan Africa by 0.1 percentage point in 2017 but retained growth estimates for 2018.1 Precisely, growth estimate in the region was increased from 2.6 percent in April 2017 forecast to 2.7 percent in July 2017 forecast, while it was retained at 3.5 percent for 2018. The slight upward revision in 2017 is attributable to an upgrade in South Africas growth prospect from 0.8 percent in April 2017 to 1.0 percent in July 2017. Despite the upward 2017 revision, 2018 forecast for South Africa was revised down from 1.6 percent in April 2017 to 1.2 percent in July 2017. Growth forecast for Nigeria remained unchanged at 0.8 percent and 1.9 percent for 2017 and 2018 respectively.

A recent report by the National Bureau of Statistics (NBS) indicates that Internally Generated Revenue (IGR) at the subnational level decreased slightly between 2014 and 2015. Specifically, the report shows that on the average, the IGR of all 36 states declined by 3.6 per cent from N707.9 billion in 2014 to N683.6 billion in 20157. A further disaggregation reveals that while IGR in 11 states improved in 2015 compared to 2014, IGR in 24 states were below their 2014 levels. As expected, Lagos state generated the most IGR during the period. Given that domestic resource mobilization is the most viable alternative to complement the shortfalls (driven by lower oil prices) in budgetary allocations to states from the federal government, state governments need to do more to improve the effectiveness and efficiency of revenue collection.
