Natural resources volatility and causal associations for BRICS countries: Evidence from Covid-19 data

Natural resource price volatility has been a major concern in recent time, especially during the COVID 19 period. Although several empirical research have looked into the oil and natural resources prices nexus with economic growth, but, our study makes a significant contribution to the present literature by estimating the long run natural resource price volatility influence on economic growth as well as the causal associations between volatility of the prices of natural resources and economic growth for BRICS economies over 1995-2020 period. To conduct empirical estimation, the study has used new and advanced (CUP-FM) continuously updated fully modified and continuously updated bias-corrected (CUP-BC) estimators for long term influences of the natural resources prices and (Dumitrescu and Hurlin, 2012) heterogeneous test for panel causality for the estimation of the causal relationship between the variables. The results provide clear evidences about the negative influence of volatility in natural resources prices, whereas positive impact of gas and oil rents on economic growth or economic performance of the BRICS economies. Moreover, bidirectional causal association is also revealed from our empirical findings to exist between economic growth and price volatility of natural resources. The findings of our study are robust to various policy implementations. It is recommended to reduce the reliance of natural resources as well as the adoption of short run and long run natural resource hedging policies to mitigate the detrimental impacts of price volatility of natural resources on economic growth and environment.

Automated summary

Natural resource price volatility is a major concern, particularly during the COVID-19 period. This study contributes to the existing literature by examining the long-term influence of natural resource price volatility on economic growth and the causal relationship between them for BRICS economies. The study employs advanced estimators and panel causality tests, finding a negative influence of price volatility on economic growth but positive impact of gas and oil rents. It also reveals a bidirectional causal association between economic growth and natural resource price volatility.
