In this study, we explore the dynamics between innovation, institutional quality, and foreign-aid flows in middle-income countries. Using an appropriate econometric model, we investigate the links between these variables in 79 middle-income countries (MICs) over 2005-2020. The results from our study show that foreign aid, institutional quality, and innovation have strong endogenous relationships. The short-run outcomes show that innovation Granger-causes institutional quality; foreign aid Granger-causes innovation; and quality of institutions Granger-causes foreign aid. The long-run outcomes indicate that institutional quality and innovation significantly affect the flow of foreign aid to the MICs. These results indicate that policy-makers in both foreign aid donor and recipient countries should pursue appropriate policies on foreign aid, quality of institutions, and innovation. For instance, in the short run, planners and evaluators in donor countries can direct their aid to MICs that have persistent challenges in improving their institutions and enhancing their innovative capabilities. In the long run, recipient countries ought to recognize that their institutional quality and innovation have a considerable impact on the inflows of foreign aid to their countries.
There is strong scientific evidence to suggest that carbon dioxide (CO2) emissions are one of the key drivers of global warming. Rising CO2 emissions across the globe have been traced back to increasing global trade and rapid industrial development powered by fossil fuels. High CO2 emissions have had an adverse effect on the quality of life and economic growth of communities across the globe. In this study, the Granger causality approach is used to examine scientifically some causal relationships between energy consumption, CO2 emissions, economic growth, and key macroeconomic variables (trade openness and foreign direct investment) in the panel of Financial Action Task Force (FATF) countries. FATF countries are signatories to agreements to adhere to good financial practices to ensure sustainable development of their economies. The empirical analysis was conducted for the period 1980 to 2020. Results indicate a strong endogenous relationship between the variables in the short and long run. The analysis suggests that careful co-curation of economic, trade, energy, foreign direct investment, and environmental management policies is needed to ensure sustainable economic development in the FATF countries. Global trade and foreign direct investment policies must foster new environmental-friendly industries and greater use of clean renewable energy among these countries.
