Over the years, agriculture has been considered as a panacea for long-term economic growth as believed by the physiocracy school of thought. Aligning this with the United Nations’ Sustainable Development Goals (specifically UN-SDG-2 which highlights zero hunger), the present study empirically complements existing studies by exploring the interactions between agriculture, trade openness, and oil rents using annual time frequency series data from 1981–2017. A series of analyses is conducted. First, a battery of non-stationarity and stationarity unit root tests are performed; these range from the traditional Augmented Dickey-Fuller (ADF) and Phillips–Perron (PP) techniques to the relatively recent Zivot Andrews (ZA) unit root test which accounts for a single structural break to ascertain stationarity properties in the variables under review. Subsequently, the recent Bayer–Hanck cointegration test in conjunction with the Johansen cointegration test was used for the cointegration analysis. Furthermore, to detect the direction of causality, the Toda-Yamamoto Granger Causality test alongside the impulse response function technique shows insightful outcomes. From the empirical results, cointegration is apparent and a long-run equilibrium relationship is traced between the outlined variables over the investigated period. The causality results and impulse response analysis highlight the existence of one-way causality links running from agriculture to trade and from trade to oil rents. The causality test results are informative, and the plausible explanation might be due to the dwindling oil market prices. More insights are elucidated in the conclusion section accordingly.

The purpose of this study is to explore the long-run and causality relationship between tourism development and the real income level in an environmental Kuznets Curve (EKC) framework for emerging industrialised economies (E7). The newness of our study to the tourism literature is the inclusion of institutional quality and tradeto the mix. The inclusion of the additional variables in the econometrics setting is worthwhile to circumvent omitted variable bias. Second-generation panel estimation techniques, in conjunction with the Driscoll-Kraay robust estimator, have been employed to accommodate cross-sectional dependency in the panel under review, as well as for robustness of coefficients and estimates. The Empirical results affirm the presence of the EKC phenomenon and tourism-induced emission in E7 economies, thereby suggesting that sustainable tourism has a deteriorating impact on economic growth in the examined industrialised countries. Similarly, real GDP per capita and non-renewable energy also dampen the quality of the environment, as indicated by the robust regression of AMG and CCEMG. Hence, an increase in non-renewable energy and tourism demand increases CO2emission in E7 economies. Additionally, we observe that the quality of institution improves the quality of the environment, thus, indicating that the role of good governance (institutional quality) improves the quality of the environment in E7. Furthermore, there is a need for a paradigm shift to sustainable tourism development alongside the adoption of the polluters pay principles to mitigate the adverse implications of the consumption of non-renewable energy. More insights are presented in the concluding section. [ABSTRACT FROM AUTHOR]

The study explores the link between electricity consumption, urbanization, and economic growth in Nigeria from 1971 to 2014. The bounds test and the Bayer and Hanck (Journal of Time Series Analysis, 2013, 34(1), 83–95) cointegration tests affirm cointegrating relationship. Electricity consumption increases economic growth in both time periods, while the impact of urbanization appears to inhibit growth. The fully modified OLS, dynamic OLS, and the canonical cointegrating regression confirm the robustness of the findings. The vector error correction model Granger causality test supports the neutrality hypothesis in the short run and the feedback hypothesis among the variables in the long run. Therefore, policies to ensure efficient electricity supply, curb rapid urbanization, and promote sustainable economic growth were suggested. [ABSTRACT FROM AUTHOR]
