The thermal profile upsurges with the enhancement of the Prandtl number and Brownian motion. Similarly, the concentration profile exhibits a rising trend with improving Lewis number and thermophoresis diffusion parameter. The surface drag and Nusselt number are computed at both the upper and lower discs to analyze the impact of the stretching discs. The thermal slip parameter enhances the heat transfer rate of the working fluid at both discs by facilitating efficient thermal energy transport and reducing thermal resistance.

Our findings indicate a statistically significant positive relationship between education expenditure and GDP, which supports human capital theory and highlights the essential role of education in achieving long-term economic prosperity. In addition to education, we find that oil prices and final consumption expenditure also positively influence GDP. However, the impact of gross capital formation is not statistically significant.
