This comprehensive meta-analysis investigates the significant factors influencing consumer decision-making in e-commerce. Predominantly focusing on the parameters of trust, perceived risk, perceived security, and electronic word-of-mouth (e-WOM), this study provides insightful revelations on their integral roles in shaping e-commerce purchasing decisions. The findings demonstrate that trust, perceived risk, perceived security, and e-WOM significantly influence consumers' e-commerce purchasing decisions. Perceived Risk plays a substantial moderating role in the relationship between Trust and e-commerce purchasing decisions, amplifying the importance of managing and minimizing risk in online transactions to cultivate consumer trust. Contrastingly, the roles of Perceived Security and e-WOM do not hold the same moderating effect on the trust-purchasing decision nexus, underscoring the direct yet unmoderated influence these factors have on e-commerce purchasing behaviors. Furthermore, The research reveals no significant size effect difference among respondents from high-income and low-income countries or between general internet users and online shoppers concerning the impact of trust on e-commerce purchasing decisions. This intriguing finding suggests the universal importance of trust in the digital purchasing landscape, irrespective of socio-economic status or the degree of e-commerce engagement. This study thus sheds new light on the complexities of e-commerce decision-making processes. It offers valuable insights for businesses aiming to enhance consumer trust and engagement in the expanding digital marketplace.

This study examines how public governance, including voice and accountability, political stability, government effectiveness, regulatory quality, rule of law, and control of corruption, affects national environmental performance in various countries. It also looks at how gross national income moderates the relationship between public governance and environmental performance. The findings show that political stability and regulatory quality positively influence environmental performance at the national level. In contrast, voice and accountability, government effectiveness, and the rule of law negatively correlate. Furthermore, in wealthier countries, voice and accountability, government effectiveness, and the rule of law enhance national environmental performance, while political stability and regulatory quality benefits diminish as income increases. These results emphasize the importance of the economic context in the interaction between public governance and environmental performance, indicating that wealthier nations are more capable of leveraging public governance for environmental improvements. The study offers crucial insights for policymakers aiming to align public governance reforms with environmental objectives, particularly in countries at varying economic development stages.

The Worldwide Governance Indicators (WGI) constitute an extensive dataset that measures the quality of public governance at the national level. The WGI framework is structured around six key governance dimensions: voice and accountability, political stability and absence of violence, government effectiveness, regulatory quality, rule of law, and control of corruption. The WGI is an invaluable tool for policymakers, researchers, and practitioners interested in comparative governance and institutional analysis.
