Abstract

This study makes a novel contribution to the empirical literature by leveraging a distinctive data set on energy price inflation to examine its influence on real gross domestic product (GDP) growth in eight sub‐Saharan African countries from 1992 to 2023. By utilizing the Augmented Mean Group and Cross‐Sectional Autoregressive Distributed Lag estimations, the study finds that, in the short term, a rise in energy price inflation does not have a significant effect on real GDP growth. However, over the long run, a 1% increase in energy price inflation is associated with a 0.06% growth decline. The adverse long‐run effects are particularly notable in Burkina Faso and Nigeria, where a 1% rise in energy price inflation reduces growth by 0.25% and 0.03%, respectively. Considering the region's dependence on fossil fuels, a shift toward renewable energy sources may be a viable strategy to cushion the economic impact of a rise in energy costs. 本研究利用独特的能源价格通胀数据集, 考察其对1992年至2023年撒哈拉以南非洲八个国家实际国内生产总值 (GDP)() 增长的影响, 为实证研究文献做出了创新性贡献。通过运用增广均值组和横截面自回归分布滞后估计, 研究发现, 短期内能源价格通胀上升对实际GDP增长没有显著影响。然而, 从长期来看, 能源价格通胀每上升1%, 实际GDP增长就会下降0.06%。这种长期负面影响在布基纳法索和尼日利亚尤为显著, 能源价格通胀每上升1%, 实际GDP增长分别下降0.25%和0.03%。考虑到该地区对化石燃料的依赖, 转向可再生能源或许是缓解能源成本上涨对经济影响的可行策略。 Este estudio aporta una novedosa contribución a la literatura empírica al utilizar un conjunto de datos distintivo sobre la inflación de los precios de la energía para examinar su influencia en el crecimiento del Producto Interno Bruto (PIB) real en ocho países del África subsahariana entre 1992 y 2023. Mediante estimaciones del Grupo de Media Aumentada y del Rezago Distribuido Autorregresivo Transversal, el estudio concluye que, a corto plazo, un aumento de la inflación de los precios de la energía no tiene un efecto significativo en el crecimiento del PIB real. Sin embargo, a largo plazo, un aumento del 1% en la inflación de los precios de la energía se asocia con una disminución del crecimiento del 0,06%. Los efectos adversos a largo plazo son especialmente notables en Burkina Faso y Nigeria, donde un aumento del 1% en la inflación de los precios de la energía reduce el crecimiento en un 0,25% y un 0,03%, respectivamente. Considerando la dependencia de la región de los combustibles fósiles, una transición hacia fuentes de energía renovables podría ser una estrategia viable para amortiguar el impacto económico del aumento de los costos energéticos.
