This article investigates the impact of Supply Chain Relationship Management (SCRM) on operational efficiency, with a specific focus on the mediating role of information sharing. SCRM has been widely recognized for promoting collaboration and improving operational outcomes in supply chains. However, the effectiveness of SCRM practices is significantly enhanced when accompanied by robust information-sharing mechanisms. The study utilizes Structural Equation Modeling (SEM) to analyze data collected from 108 supply chain professionals in the Sunyani Municipality, Ghana. The results show that information sharing plays a critical role in mediating the relationship between SCRM and operational efficiency, highlighting its importance as a mechanism for facilitating better coordination, reducing operational costs, and improving lead times. These findings offer valuable insights into how inter-organizational collaboration and effective information exchange contribute to operational improvements in supply chains, particularly within the pharmaceutical sector in developing economies. The study contributes both theoretical and practical perspectives on supply chain management.  

Technology, innovation, and economic shocks have transformed global financial markets. The latest global health pandemic has been compared to the 2008 global financial crisis, as investors, lawmakers, and regulators worldwide worried about economic collapse. Johannesburg Stock Exchange is Africa's largest. The JSE names SIFIs, whose failure would threaten SA's economy. Uncertainty increases failure risk, as seen in the GFC and COVID-19. This study examined how economic shocks affected investor confidence in South Africa's growing financial market, the JSE 15 Index. Analysis of data from January 1999 to December 2023 examined short- and long-term stock market impacts, the role of the South African Reserve Bank (SARB) in stability, and investor conduct during crises. The two economic shocks' effects on JSE 15 index stock prices were examined using Autoregressive Distributed Lags (ARDL) and correlation analysis. ARDL determines short- and long-term macroeconomic cointegration. Three macroeconomic variables—interest rates (T-Bills), inflation (CPI), and real effective exchange rate (REER)—are used to track their fluctuation during crises. The analysis shows a shift in investor confidence reflected in a considerable decline in financial performance throughout the crisis. As investors' risk tolerance differs, diversification benefits made abnormal returns unimportant. SARB's monetary and fiscal policies mitigated the pandemic. South African investors were also wary due to internal issues. The study shows that global commodity prices and currency rate volatility affect investor confidence more than domestic policy in emerging economies, adding to behavioural finance.
