Dynamic impact of shadow economy and corruption on environmental sustainability: What role renewable energy consumption play in case of South Asian Economies

The South Asian region has a wide range of problems that significantly influence its path towards environmental sustainability. The region's rapid population expansion, rising urbanization rates, rising industry, and increasing resource demands primarily determine these challenges. The quest for environmental sustainability in this setting is complex and multidimensional, made more difficult by the shadow economy, corruption, and the need to improve renewable energy alternatives. Therefore, the current study examines the multifaceted and interrelated dynamics of the shadow economy, corruption, economic inequality, and environmental sustainability in South Asian nations from 2004 to 2018. We have used sophisticated methodological strategies to tackle cross-section dependence, non-stationarity, and heterogeneity issues by employing a pooled mean group (PMG). However, we use panel FMOLS and DOLS techniques for robustness checks. The findings of the PMG analysis show that the shadow economy, corruption, and industrialization significantly negatively impact environmental sustainability. On the other hand, renewable energy consumption and urbanization are positive and substantial elements that lead to improved environmental sustainability. The robust procedures applied to check the consistency of the estimators also confirmed the long-run relationship among variables. Research findings suggest that reinforcing legal frameworks for environmental rules is crucial for adherence. Incentives such as legal protection and financial rewards can encourage environmental responsibility among businesses, reducing shadow economy operations and risks. Promoting renewable energy resources and urbanization helps to support a sustainable green economy.
