The article "Effect of Public Investment on Health Population: A Review of BRICS Countries" by Tanveer Ahmad Shahid, Saif Ur Rahman, Salman Masood Sheikh, and Rubina Allahrakha explores the impact of foreign direct investment (FDI) on public health and economic development in BRICS countries. The authors review existing literature and empirical studies to analyze how FDI affects population health and economic growth. They highlight that while FDI can enhance economic growth and technological advancements, it also has mixed effects on health outcomes. The study finds that increased FDI can improve life expectancy and reduce mortality rates, particularly in developing countries like South Africa and Ghana. However, the relationship between FDI and health is not well understood, and more research is needed to explore this relationship across multiple countries using various methodologies. The authors also discuss the role of public policy in shaping public health and economic resilience, emphasizing the importance of addressing endogeneity and causality issues in future studies. The study concludes by suggesting that further research should use dynamic vector error correction models (VCEM) to better understand the long-term impacts of FDI on public health and economic growth.The article "Effect of Public Investment on Health Population: A Review of BRICS Countries" by Tanveer Ahmad Shahid, Saif Ur Rahman, Salman Masood Sheikh, and Rubina Allahrakha explores the impact of foreign direct investment (FDI) on public health and economic development in BRICS countries.
