ABSTRACT As a strategy, countries seek ways to improve national income and, at the same time, keep carbon emissions minimal. Such scenario is captured by respective economies' productivity (CP) scores. Remarkably, it expected that technological advancements could be harnessed achieve CP. Hence, many have publicly invested in green technologies R&D, including energy efficiency, renewables, nuclear, hydrogen, and storage. However, existing studies did not verify specific contributions of these advances CP, leaving notable void literature. current research verified various technology R&D Based on panel data from 2003 2022, this study implemented novel instrumental variable quantile regression technique for updated insights. The uncovers heterogeneous each innovation variant distributions effects underscore country's changing economic structures varied implementation paths. policy consistency key driving CP ensuring environmental compatibility. renewable, efficiency contributed most significantly across distributions. hydrogen storage least Therefore, allocating more funds all R&Ds boost energy‐enhancing overall sustainability expedient. proactive integrative policies consistent with SDGs 7 13 would reduce while escalating income. Meanwhile, isolated inconsistent funding should discouraged progress. A robustness evaluation based SIVQR produced corroborative evidence.

The stock market operates on informed decisions based information gathered from heterogeneous sources, encompassing diverse beliefs, strategies, and knowledge. This study examines the validity of rational bubbles in prices, focusing eight African markets: South Africa, Nigeria, Kenya, Egypt, Morocco, Mauritius, Ghana, Botswana. Utilizing newly developed econophysics-based unit root tests Dynamic Conditional Correlation Multivariate Generalized Autoregressive Heteroskedasticity (DCC MGARCH) models, authors analyzed daily data 1996 to 2022. Our findings indicate that these markets experienced at various points, often followed by bursts. These coincided with significant economic changes, suggesting a strong link between behavior growth. For instance, financial crises, political instability, global downturns significantly influenced bubble formation bursts markets. reveals market-specific events, such as regulatory changes shifts investor sentiment, also contributed occurrence bubbles. Three key policy options are proposed address studied including, enhancing frameworks monitor mitigate formation, improving literacy among investors promote decision-making, strengthening policies stabilize macroeconomic conditions reduce vulnerability external shocks. By implementing measures, policymakers can enhance stability foster sustainable growth
