Global value chains (GVC) have propelled substantial expansion in international trade across the globe over the last two decades. Yet, the institution-GVC nexus in Africa suffers complete neglect in literature. Therefore, we evaluate the impact of different components of political and economic institutions on backward (BWDGVC), forward (FWDGVC), total GVC participation, and GVC position (upstreamness) in Africa. Using system-GMM with United Nations Conference on Trade and Development GVC database (UNCTAD-Eora MRIO) for 47 African countries over the period 2000-2018, the key findings show that the effects of the political and economic institutions on GVC participation are diverse. Specifically, property rights, government spending, monetary freedom, and tax burden negatively affect BWDGVC participation while government integrity, investment freedom, and financial freedom stimulate the BWDGVC. Also, all the components of institutional quality that propel BWDGVC, hinder FWDGVC participation and upstreamness, except investment freedom which promotes both BWDGVC and FWDGVC. Nonetheless, property rights, government integrity, monetary freedom, financial freedom, and tax burden engender total GVC participation, whereas government effectiveness, and investment freedom hinder the total GVC participation. Furthermore, good political institutions promote BWGVC and total GVC but reduce upstreamness. Thus, institutions are fundamental drivers of GVC participation in Africa.
Crude oil and natural gas are crucial to the Russian economy. Therefore, this study examined the interconnections between crude oil price, natural gas price, and Russian economic policy uncertainty (EPU) over the period 1994–2019 using multivariate DCC-MGARCH models. The findings show that there are strong interconnections (co-movement) between the energy prices and EPU in Russia, and that it might be misleading to assume independence or neutrality between the variables. Although Russia is also a crucial player in both the natural gas and the crude oil markets, this study reveals that there is a stronger co-movement of the EPU with gas price than with the oil price. Russia is the largest exporter of natural gas and the second-largest producer; it is plausible that the natural gas price correlates with EPU more than the crude oil price. Further, the correlation between gas price and EPU and the correlation between crude oil price and EPU have similar patterns. Each declines almost in the same period and, equally, increases concurrently. In addition, the results revealed that significant global shocks and crises, such as the 2008 global financial crisis, the 2014–2017 Russian financial crisis, the 9/11 terrorist attack, and the Russo–Ukrainian conflicts, influence the interconnections between the energy prices and Russian EPU.
Purpose The current study aims to ascertain the association between tourism development, economic growth and environmental quality by using the short-run and long-run autoregressive distributive lag model. Design/methodology/approach Tourism development has a major role to play in improving a nation’s economic growth. However, it is also blamed for exacerbating environmental pollution because of its massive use of energy (non-renewable energy). Findings The major findings of this research show that renewable energy (RE) use and gross domestic product (GDP) negatively impact carbon dioxide (CO2) emissions in South Africa. Tourism arrivals and CO2 emissions negatively impact GDP, while capital positively impacts GDP in the long run. Practical implications This research recommends the use of RE, since it reduces carbon emissions, and capital, as it remains the major driver of economic growth. Originality/value The originality of the current research is that it uses long-period annual time series data from 1971 to 2019 of South Africa, one of the largest tourist nations in Africa. To the best of the authors’ knowledge, no studies have examined South Africa in this context and minimal research has been conducted to ascertain the impact of the tourism industry on the environment, despite the accusations directed toward it.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
