This paper investigates the empirical relationship between carbon dioxide emissions, economic growth and energy use in post-communistic countries during 1990-2018. Pedroni's (1999 panel cointegration test discovered cointegrating relationship between the variables. To distinguish short-and long-term effect, as well as to account for homogeneity caused by previous common socio-political system and current country specific characteristics, Pesaran's et al. (1999) Pooled Mean Group estimator is employed. PMG estimates identified short-and long-term relationship between energy use and CO 2 emissions and short-term relationship between CO 2 emissions and economic growth. Finally, the Dumitrescu and Hurlin's (2012) Granger non-causality test for heterogeneous panels revealed bidirectional causality between CO 2 emissions, energy use and economic growth.
Current study sheds the light on the financial development-energy nexus in 32 Belt and Road economies during 2000-2015. Financial development is proxied by domestic credit to private sector. We first examine the order of integration by employing five different panel unit-root tests. Further, we confirm long-term relationship between the variables by running Pedroni and Kao panel cointegration tests. Fully modified ordinary least squares (FMOLS) regression reveal positive long-term relationship between financial development and energy use. Results of Dumitrescu-Hurlin panel causality test fail to reveal causal relationship between financial development and energy in our sample.
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.
