  Oil remains a strategic asset at the heart of contemporary geopolitical rivalries. China’s rise to become the world’s largest importer and the United States’ transformation into a major producer and exporter have profoundly altered the energy balance of power, reinforcing the interdependence between oil markets and bilateral geopolitical tensions. This article examines the existence and nature of an asymmetric relationship between oil price fluctuations and geopolitical tensions between China and the United States, distinguishing the effects of price increases and decreases and their dependence on risk regimes. The analysis is based on monthly data covering 2000–2024 and employs a nonlinear econometric approach that combines an NARDL model for asymmetric cointegration, a Quantile VAR (QVAR) model to capture conditional effects by risk level, and an EGARCH model to analyze the asymmetric transmission of geopolitical uncertainty to oil volatility. The results show that rising oil prices significantly intensify Sino-American geopolitical tensions, while falling prices have a weaker and less persistent effect. This asymmetry is particularly pronounced during periods of high international instability. Furthermore, geopolitical tensions significantly increase oil price volatility, with a leverage effect indicating that negative geopolitical shocks have a disproportionate impact on energy markets. These results suggest that the asymmetry in the oil-geopolitical transmission reflects differentiated energy vulnerabilities and distinct strategic behaviors between China and the United States. The study underscores the importance of oil as a vector of asymmetric interdependence and as an amplifier of international tensions, with major implications for energy security policies, financial market stability, and global energy governance.

  This study examines the impact of school infrastructure on pupils' academic performance in Cameroon, addressing concerns over persistently low schooling rates and educational outcomes in primary schools. Using cross-sectional secondary data from the PASEC survey conducted across ten Francophone African countries, covering 31,213 pupils from 671 schools in Cameroon. The data were analyzed using descriptive statistics and robust Ordinary Least Squares (OLS) regression. The findings reveal that school infrastructure has a significant positive effect on pupils’ academic performance, suggesting that improvements in classroom conditions, access to educational resources, and overall school facilities correlate with better academic outcomes. Additionally, several control variables, including electricity at home, parental involvement in education, access to study guides, and the availability of basic learning materials, also show a positive relationship with academic performance. However, certain factors, such as school canteens, catch-up lessons, and WiFi access at home, exhibit unexpected negative effects on pupils' performance, indicating potential distractions or inefficiencies in their implementation. The study concludes that investment in school infrastructure is crucial for enhancing educational quality in Cameroon. It emphasizes the need for targeted interventions focusing on classroom construction, the provision of teaching materials, and inclusive infrastructure to support diverse student needs. From a policy perspective, the Cameroonian government should address urban-rural disparities through decentralization, ensuring that local authorities play an active role in school infrastructure development. The findings suggest that while digitalization is not yet a priority, fundamental infrastructure improvements, such as classrooms, desks, potable water, and libraries, should be prioritized to create a more conducive learning environment.
