The influx of massive revenues during periods of abnormally high oil prices creates enormous challenges for policymakers in oil producing countries. In Nigeria, the prudent utilisation of oil revenues has remained elusive for policymakers over time. While the country has earned sizeable oil revenues from its natural endowment, poverty and income inequality have been persistent. This study offers an elaborate econometric analysis which tests the sensitivity of a number of key macroeconomic indicators to oil revenue shocks, using the Impulse Response Functions (IRFs) and Variance Decomposition (VDC) techniques within a Vector Autoregressive (VAR) framework. The sensitivity analysis offers a novel contribution to the academic and policy literature on the macroeconomic responses to oil windfalls in Nigeria by testing for an institutional quality variable. The inclusion of this variable is in recognition of the important role played by the domestic institutional context in shaping the policy responses adopted by successive Nigerian governments to oil windfalls over time. The sensitivity analysis supports the general view that fluctuations in oil revenues have resulted in inflation, lower output growth and real exchange rate appreciation in Nigeria. Importantly, the institutional variable was found to be significant. This finding is consistent with the general assessment of fiscal performance in Nigeria during oil windfalls as being driven by domestic institutional dynamics, as ostentatious public consumption widened fiscal deficits, and government spending was highly pro-cyclical during windfall episodes. In conclusion, the study offers appropriate policy recommendations, which involve a combination of economic, socio-political and institutional actions that may be adopted to enhance the management of future oil windfalls in Nigeria.

Nigeria Economic Update (Issue 12)

The Naira sustained its appreciation trajectory at the parallel market in the review week. Precisely, naira gained 13.3 percent (Week-on-Week) to exchange at N390/$ on March 24, 2017. Reduced pressure on the naira followed moderation in speculative activities as a result of increased forex sales and intervention by the CBN (daily intervention of $1.5 million at the interbank market.) The aim of CBN interventions (narrowing the gap between interbank and parallel market rates) seems to be on course with the continued appreciation of the naira at alternative markets. While current approach of the apex bank proves effective in improving international value of naira in the short term, however, it is expedient that the bank articulates clear and credible flexible exchange rate policy to sustain the momentum and enhance confidence in the forex market in the medium term. Nonetheless, the sustainability of the exchange rate gains is partly dependent on the prospect of crude oil price and production which is outside the purview of the monetary authorities.

Recent ranking by the World Bank, portrayed Nigeria as having a poor business environment based on the ease of doing business in 2016. Although, Nigeria moved one position forward from previous (2015) ranking, to attain the 169th position out of the 190 global economies reviewed4. This poor rating is resultant of a myriad of factors, including: difficulties in starting a business, enforcing contracts, inaccessibility to credit, tax payment issues, as well as unreliable supply of energy, and labour market regulations. Going forward, improving the efficiency of tax administration by adopting the latest technology to facilitate the preparation, filling and payment of taxes will be beneficial for the business community.
