The causalities between carbon dioxide emissions, renewable and nonrenewable energy consumption, economic growth, and urbanisation were examined for the panel of five countries (Argentina, Brazil, Paraguay, Uruguay, and Venezuela) from Southern Common Market, over thirty-five years , using a panel vector autoregression. The empirical analysis pointed to the existence of bi-directional causality between the consumption of fossil fuels, economic growth, consumption of renewable energy, and carbon dioxide emissions; and a uni-directional relationship between the consumption of renewable energy and urbanisation. The research also proves that the countries from Southern Common Market are dependent on fossil fuels consumption and that urbanisation process is highly linked with the consumption of this type of energy. Additionally, it was found that these countries have low renewable energy participation in their energy mix. Nevertheless, a substitutability effect between the consumption of renewable energy and the consumption of fossil fuels, as a possible response to periods of scarcity in reservoirs, was detected. Policymakers of Southern Common Market countries should speed up the deep reforms regarding renewable energy to mitigate environmental degradation.

This study examines the impacts of globalization and economic freedom on the economic growth of a group of 24 developing countries from the Latin America and Caribbean over a time span ranging from 1995 to 2015. We have constructed two models, one with the globalization's overall value and another with the political, social and economic dimensions of globalization. Our results point out to the fact that globalization has had a positive impact on the economic growth of these countries in the long-run, as well their economic and social dimensions. Still, the political dimension of globalization did not show any statistically significant effect upon growth. In addition, we have found evidence of a negative impact resulting from economic freedom on the economic growth of these Latin American and Caribbean countries in the long-run. In the short-run, the results have indicated that electric power consumption (in all estimations) and social globalization (in only one estimation) were able to promote the economic growth of these countries. Finally, the negative and significant coefficient of the error correction mechanism in all estimations points out to the presence of cointegration/long-memory relationships between the variables. This study aims to contribute to the enrichment of the globalization-growth and economic freedom-growth literature in the way that it attempts to overcome some of the flaws identified in previous studies. In our analysis we have identified and corrected the presence of outliers, which are quite often neglected, and if not controlled can actually compromise the macro-economic analysis of this region. The results from this study should primarily contribute to guide policymakers in their decisions, thus helping them to draw growth-promoting policies in their respective countries.
