摘要

本研究提供了全球危机影响尼日利亚通货膨胀的证据。本研究利用均值和方差检验模型分析了1999Q1-2022Q4期间的数据，发现尼日利亚通货膨胀的幅度和波动性随着危机而变化。虽然通货膨胀率在全球金融危机后有所下降，但其波动性在危机后上升。相比之下，2019冠状病毒病大流行后，通货膨胀率上升，波动性增加。全球金融危机后通胀的下降与实际GDP的增长有关，表明其在全球金融危机后降低通胀的产出效应。COVID-19疫情后，实际GDP没有出现任何显著增长，这表明疫情之后出现了滞胀。这些结果还表明，2019冠状病毒病对尼日利亚通胀动态的影响与全球金融危机的影响不同。

Global crises and inflation dynamics in Nigeria

This study provided evidence that global crises affected the inflation in Nigeria. Analysing data over the 1999Q1-2022Q4 period within the Test of Means and Variances model, this study finds that the magnitude and volatility of inflation in Nigeria changed with crises. While inflation declined after the global financial crisis (GFC), its volatility rose after the crisis. In contrast, inflation rose after the COVID-19 pandemic while the volatility increased. The decline in inflation after the GFC was associated with increase in real GDP, suggesting its inflation-reducing output effects post-GFC. The absence of any significant increase in real GDP after the COVID-19 shows that the pandemic was trailed by stagflation. These results also show that COVID-19 impacted on inflation dynamics in Nigeria differently from how GFC had.
