Abstract

The COVID-19 pandemic has profoundly impacted global economics; now, there are concerns about the potential onset of a recession as central banks raise interest rates to combat the persistent inflation problem. This study employed a comparative approach, focusing on G20 countries, to analyze the likelihood of a recession in the aftermath of the COVID-19 crisis.

Using LSTM (long short-term memory) and extreme gradient boosting (XGBoost), we investigated the economic performance of selected G20 countries via various macroeconomic variables, e.g., real GDP growth, unemployment rates, inflation, and interest rates. More specifically, we did a comparative analysis of long short-term memory approaches that will be used to explain possible downturns in their economies. The actual versus forecasted values showed a robust fit, as evidenced by the root mean square error (RMSE). Each country had different forecasted values beyond the actual data. The empirical results showed mixed results, and we expected negative growth rates across the selected G20 countries due to rapid inflation. However, some countries like South Africa, Indonesia, and Japan showed consistent positive growth despite inflationary pressures. The United States, on the other hand, indicated a slower growth rate but also showed a positive rebound.
