The purpose of this study is to empirically analyse the fiscal revenue implications for oil-dependent African countries in the face of low-carbon energy transition (LET).

The study combined the novel fully modified ordinary least squares, dynamic ordinary least squares and canonical cointegrating regressions estimators to analyse secondary data between 1990 and 2020 for the three major oil-dependent African Countries (Algeria, Angola and Nigeria).

The result shows that LET reduces oil revenue and non-revenue for specific countries (Algeria, Angola and Nigeria) and the panel, suggesting that low-carbon energy transiting is lowering the fiscal revenue of oil-dependent African nations.

The seeming weakness of this study is its inability to broaden the scope to include all oil-producing African economies. However, since the study selected Africa’s top three oil-producing states, the sample can serve as a model for others with lesser crude oil outputs.

Oil-dependent African countries must urgently engage in sincere economic diversification in sectors like industry and manufacturing, the service sector and human capital development to promote economic transformation that will enhance fiscal revenue.

With the pace of energy transition towards low-carbon energy, it is not business as usual for oil-rich African countries (Algeria, Angola and Nigeria) due to fluctuating demand and price. As a result, it becomes worthy to examine how the transition is affecting oil-dependent economies in Africa. Also, this study’s method is unique as it has not been used in a similar study for Africa.

This study aims to investigate the contingent roles real effective exchange rates (REERs) play in mediating the effects of oil revenue on the agriculture sector value-added in 25 major and minor oil-exporting (MIOEC) countries during the period of 1975–2014.

The panel autoregressive distributed lag (ARDL) estimator proposed by Pesaran et al. (1999) was relied upon to achieve the objectives of the study. This estimator involves a pool of small cross-sectional units over a long-time span that covers for 25 oil-exporting countries over 39 years (1975–2014).

This paper reveals the following findings. Firstly, oil revenue has a direct negative effect on agricultural value-added in the short- and long-term. This finding holds for full sample and subsamples of major oil-exporting (MAOEC) and MIOEC countries. Further assessment reveals that the magnitude of the impact is larger for MAOEC than that of the MIOEC. Secondly, the finding for the long-run effect shows that the contingent effect of real exchange rate on the nexus between oil revenue and agricultural value-added is negative and statistically significant at the conventional level for the full sample. This suggests that, in the long-run, the appreciation in real exchange rates exacerbate the negative marginal effects of oil revenue on agricultural value-added in all oil-exporting countries. However, when sub-samples of MAOEC and MIOEC are considered, the contingent effect disappeared (become insignificant) in MAOEC while it is positive and statistically significant in MIOEC. Thus, in the long-run, the appreciation in real exchange rates diminishes the negative marginal effects of oil revenue on agricultural value-added in MIOEC. While oil revenue has a direct negative effect, its effect is also moderated by the variations in REERs in MIOEC in the long-run. Finally, in the short-run, fluctuations in the real exchange rate do not matter for the nexus of oil revenue and agriculture sector in these countries whether minor or MAOEC countries.

This study contributes to the debate in the empirical literature on the Dutch disease effect and “oil curse”. Using the appropriate panel ARDL empirical framework, it provides evidence on how exchange rate variations in the oil-exporting countries influence the nature of the effects of the oil revenue on agricultural sectors in the long-run but not in the short-run. Contingent effects of REERs only appear to exist in MIOEC in the long-run.

Persistent wave of armed conflicts – militancy and terrorism – and the mono-cultural structure of the Nigerian economy, as well as extensive reliance on revenue from crude oil, highlights how external vulnerabilities, weakening internal structure and insecurity could significantly exacerbate public revenue loss. Understanding the nature, trend and impact of these factors on government revenue is one of the questions that still remain unsolved. The purpose of this paper is to examine the impact of global oil prices, militancy and terrorism on government revenue in Nigeria.

The study focusses on the state-failure and frustration-aggression hypotheses to explain the nature and trend of armed conflicts in Nigeria. The autoregressive distributed lag (ARDL) model is used to examine the effect of global oil prices, militancy and terrorism on government revenue.

The study reveals that crude oil price, terrorism and militancy have significant negative effect on government revenue in short- and long-run Nigeria. Evidence from the study therefore supports the theory that macroeconomic fluctuation is largely determined by endogenous and exogenous factors in Nigeria.

In view of this review, future studies should empirically analyse the interactive impact of militancy, terrorism and global oil prices on government expenditure or a combination of government revenue and expenditure.

The study provides evidence on the role of internal and external factors on macroeconomic fluctuation, and recommended appropriate suite of policies that could mitigate external and internal vulnerabilities, especially during upsurge in armed conflicts.

The purpose of this paper is to examine the sustainability of fiscal policy in Nigeria by disaggregating the economy into oil and non-oil segments.

Owing to the enormous influence of the oil revenue, the study distinguishes between the oil and non-oil fiscal balances. In addition, it abstracted from the endogenous macroeconomic environment, therefore, fiscal policy sustainability is investigated on the basis of the responses of the government primary balance to changes in deficits and debt levels. The models are estimated with time-series data from 1970 to 2011 using the Johansen estimation techniques.

The results from the estimations performed suggest that government responds more to deficit targets than debt targets. However, this differs in the non-oil segment, as the fiscal policy actions of government do not consistently respond to either deficit or debt targets. Given this, the overall economy and the oil segment have revealed a strong fiscal sustainability over the years while fiscal policy is unsustainable in the non-oil segment.

The major limitation of this study is the unavailability of data on government expenditure resulting from oil revenue. Therefore, it would be imperative to reinvestigate the specifications adopted in this study in follow-up studies.

The study includes implications for policy makers, especially in Nigeria and other oil-producing countries, to detect the extent to which the economy should rely on the oil revenue stream as the main source of revenue to government. The proceeds from the oil endowment have not yet trickled down to the rest of the economy where real economic activity could be carried out which would eventually lead to more tax revenue for the government.

To assess the sustainability of fiscal policy in an oil-rich economy such as Nigeria, it is imperative to detect the influence of oil funds on both government revenue streams and expenditure decisions. This study has made this distinction.

A widely held belief before the 1990s – referred to as the oil-blessing hypothesis – was that oil discovery and production should promote economic growth and development and lead to poverty reduction. However, the so-called ‘oil-curse’ hypothesis, postulated by Sachs and Warner in 1995, challenged this belief, thus provoking a heated debate on the theme. The oil-curse hypothesis has been traditionally tested by means of cross-sectional and panel-data models. The author goes beyond these traditional methods to test whether the presence of spatial effects can alter the hypothesis in oil-producing African countries. In particular, this paper aims to investigate the effects on economic growth of oil production, oil resources and oil revenues along with the quality of democratic institutions, investment and openness to trade.

A Durbin spatial model, a cross-sectional model and panel-data model are used.

First, the validity of the spatial Durbin model is vindicated. Second, consistently with the oil-curse hypothesis, oil production, resources, rent and revenues have a negative and generally significant effect on economic growth. This result is robust for across the panel data, spatial Durbin and spatial autoregressive models and for different measures of spatial proximity between countries. Third, the author finds that the extent to which the business environment is perceived as benign for investment has a positive and marginally effect on economic growth. Additionally, economic growth of a country is further stimulated by a spatial proximity of a neighbouring country if the neighbouring country has created strong institutions protecting investments. Fourth, openness to international trade has a positive and marginally significant effect on economic growth.

This paper examines theories and studies that have been done before. However, as the related literature on the growth–resource abundance nexus has rarely examined spatial effects, this study seeks to test jointly the spatial effect and the neighbouring effect on the oil curse hypothesis.

While the relationship between natural resource rent and economic growth is well documented in the literature, not much robust analysis has been done to estimate the causative relationship between oil resource rent and economic growth in Ghana. This might be due to the fact that commercial production of crude oil started not long ago in Ghana. This paper aims to examine the causal relationship between oil resource rent and economic growth for the period of 2011 to 2020 in Ghana.

The study incorporates economic growth as a function of oil resource rent, non-oil revenue, foreign direct investment, capital and interest rate in a Cobb–Douglass production function/model. The study used four different estimation strategies including the autoregressive distributed lags model, Toda–Yamamoto test approach, nonlinear autoregressive distributed lags model and nonlinear Granger causality.

The main finding revealed that 1% increase in oil resource rent generates 0.84% increase in economic growth of Ghana in the long run. Contrary, the authors find an insignificant positive effect of oil resource rent on economic growth of Ghana in the short run for the period under study. The result from the Toda–Yamamoto test approach also showed a unidirectional causality running from oil resource rent to economic growth of Ghana, providing evidence in support of the resource blessing hypothesis in Ghana. The results are robust to two different alternative estimation strategies.

The causal relationship between crude oil resource rent and economic growth is examined.

The purpose of this study is to determine the extent illicit flows affect the oil and gas revenue generation in Nigeria specifically the activities concerning oil theft.

A qualitative approach using a systematic quantitative assessment technique was used to select peer-reviewed articles and reports that discussed crude oil theft in Nigeria. This was followed by the use of empirical evidence and content analysis.

Crude oil theft in Nigeria accounts for 10% of illicit financial flows (IFFs) from Africa annually and this amounts to US$6bn annually.

Oil theft is a new subject area of public policy and academic research; data, secondary literature and peer-reviewed journal articles are limited. This paper was from the public sector perspective only.

This study is one of the few works to highlight the connection between crude oil theft and IFFs.

As with many other developing economies, Egypt pursues a policy of keeping domestic energy prices below border prices. This entails both financial subsidies to energy producers and users, and significant opportunity costs in terms of foregone foreign and government revenues. This article details the price structure and uses two models to assess the macroeconomic and microeconomic impacts of policies designed to correct the domestic/border price disparity.

This paper seeks to explore the factors behind the slow growth of economies with abundant oil and gas resources, despite the opportunities these resources potentially represent.

The building blocks of standard economic growth models and the implication of natural resource utilisation is the methodological and analytical approach adopted. A qualitative analysis of the impact of oil and gas activities on the growth of the Nigerian economy is carried out using relevant macroeconomic indicators.

The oil and gas sector is imbued with enormous linkage potentials that can stimulate other sectors to generate endogenous growth. Emphasis on the extraction and export of oil and gas subverts technological progress, stifles the revenue earning potential of the economy and stultifies the effectiveness of factors of production, thereby retarding economic growth.

Data on technological input into oil and gas activities could not be obtained, but the changing pattern of productive capacity, especially in the downstream sub‐sector, is used as a measure of technological change.

Oil‐ and gas‐abundant economies can exploit potential comparative advantage by creating favourable conditions in value‐adding oil and gas activities. Through spill‐over effects a wide range of economic activities evolves, with concomitant market expansions. Positive externalities for learning‐by‐doing arising from this process can lead to endogenous technological progress to drive sustainable economic growth.

The findings show that rather than reliance on foreign exchange revenues from oil and gas, creating the appropriate conditions for the effective domestic utilisation of oil and gas resources to bolster inter‐sectoral linkages is a more virile strategy for oil‐and‐gas driven economic growth.
