How institutional quality and peace and environmental regulations influence sustainable growth in G20 countries

Sustainable development has become a policy item on the global agenda, especially among the G20 countries, which account for a significant portion of the world's economic activity and environmental impact. The paper examines how institutional quality, peace, and environmental regulations can be leveraged to stimulate sustainable growth from 2000 to 2023. With progressive econometric applications, such as the Method of Moments Quantile Regression (MMQR) and the BSQR, we provide compelling evidence on the conditional distribution of the sustainable progress markers. The judgments focus on the positive and essential works of powerful organizations, the meaning of peace, and the harsh environmental policies, as well as sustainable development. Notably, these findings indicate that these relationships are not homogeneous across different quantiles, and they portray varying effects of the variables on the economies, with distinct levels of sustainability attainment. For example, even though peace is central in high-performing nations, it simultaneously becomes one of the driving forces behind low-performing nations on the sustainability scale. These statements have extensive policy consequences. Sustainable development can be achieved through peace and institutional strengthening, providing a strong foundation. On the same note, environmental laws can be utilized to achieve both ecological and economic benefits. The analysis will focus on the micro-levels of individual countries or regions and incorporate new determinants, including artificial intelligence and digitalization, into the definition of sustainable growth directions. The paper has contributed to the ongoing debate on achieving inclusive and sustainable development in an era of global challenges.
