Past trends of FDI inflow into BRICS and G-7 economies showed that BRICS economies had noticed a higher compounded average annual growth rate in FDI compared to G-7 economies in the preceding periods. The best-suited ARIMA model's anticipated value of FDI inflow shows an increasing trend in BRICS and a steady and dropping trend in the G-7. Comparative results of the predicted values of FDI inflow showed that BRICS would have positive FDI inflow while the G-7 would follow a declining trend.
