While socioeconomic gradients in regional health inequalities are firmly established, the synergistic interactions between socioeconomic deprivation and climate vulnerability within convenient proximity and neighbourhood locations with health disparities remain poorly explored and thus require deep understanding within a regional context. Furthermore, disregarding the importance of spatial spillover effects and nonlinear effects of covariates on childhood stunting are inevitable in dealing with an enduring issue of regional health inequalities. The present study aims to investigate the spatial inequalities in childhood stunting at the district level in Pakistan and validate the importance of spatial lag in predicting childhood stunting. Furthermore, it examines the presence of any nonlinear relationships among the selected independent features with childhood stunting. The study utilized data related to socioeconomic features from MICS 2017–2018 and climatic data from Integrated Contextual Analysis. A multi-model approach was employed to address the research questions, which included Ordinary Least Squares Regression (OLS), various Spatial Models, Machine Learning Algorithms and Explainable Artificial Intelligence methods. Firstly, OLS was used to analyse and test the linear relationships among selected variables. Secondly, Spatial Durbin Error Model (SDEM) was used to detect and capture the impact of spatial spillover on childhood stunting. Third, XGBoost and Random Forest machine learning algorithms were employed to examine and validate the importance of the spatial lag component. Finally, EXAI methods such as SHapley were utilized to identify potential nonlinear relationships. The study found a clear pattern of spatial clustering and geographical disparities in childhood stunting, with multidimensional poverty, high climate vulnerability and early marriage worsening childhood stunting. In contrast, low climate vulnerability, high exposure to mass media and high women's literacy were found to reduce childhood stunting. The use of machine learning algorithms, specifically XGBoost and Random Forest, highlighted the significant role played by the average value in the neighbourhood in predicting childhood stunting in nearby districts, confirming that the spatial spillover effect is not bounded by geographical boundaries. Furthermore, EXAI methods such as partial dependency plot reveal the existence of a nonlinear relationship between multidimensional poverty and childhood stunting. The study's findings provide valuable insights into the spatial distribution of childhood stunting in Pakistan, emphasizing the importance of considering spatial effects in predicting childhood stunting. Individual and household-level factors such as exposure to mass media and women's literacy have shown positive implications for childhood stunting. It further provides a justification for the usage of EXAI methods to draw better insights and propose customised intervention policies accordingly. [ABSTRACT FROM AUTHOR]

Intra-industry trade has a paramount value in the theory of international trade due to the reason that it establishes the base for exploiting economies of scale and product differentiation, which ultimately ensures the existence of comparative advantage. The current research is an endeavour to examine the determinants of intra-industry trade through Augmented Gravity Equation (AGE) and the potential of intra-industry trade through revealed comparative advantage (determined by the Balassa index); in the selective industries of Pakistan, with its top eleven trading partners. For this purpose, the top five exporting industries of Pakistan are selected which include textile and clothing, agro-food, engineering goods and manufacturing goods, leather and minerals and metals. Data for the period from 2003 to 2016 is used for analysis. The random effects panel data model is used to estimate the independent factors of IIT such as the difference in market size, the difference in per capita income, common border, economic distance, and free trade agreement. The results calculated through AGE mainly showed that the difference in market size and per capita income significantly alter the course of IIT in Pakistan due to variations in the development stage between Pakistan and its trading partners. Further, the RCA showed the highest trend in the textile and clothing industry and the lowest in the transportation industry of Pakistan. Finally; it is suggested that in Pakistan, innovative and differentiated goods are required to be produced to attain economies of scale and capture international markets. In this way, its balance of payments can be improved. [ABSTRACT FROM AUTHOR]
