Testing the Ability of Keynesian Phillips Curve Dynamics to Affect the Sudan's Real Economic Growth During the Period (2000-2022)

الملخص

The study tested\the ability of Keynesian Phillips curve dynamics to affect the Sudan's real economic growth during the period (2000-2022), and used the econometrics methodology through the nonlinear autoregressive distributed lagged mode (NARDL), and the results revealed that there is a long-run equilibrium relationship between Keynesian Phillips curve dynamics and real economic growth, the imbalance is corrected by -3.27, that is, within approximately three months, and the increase in the inflation and unemployment rates by 1% leads to a decrease in the real economic growth by -0.15, -0.52, while a decrease in the inflation rate leads to a decrease in the real economic growth, which means that the real economic growth is inflexible to  a decrease in the inflation rate, and the decrease in the unemployment rate by 1%, leads to an increase in the real economic growth by 0.37, but this increase is statistically not significant, it recommended that to choose the appropriate economic policy that works to achieve desirable rates of  inflation and unemployment in order to reach a higher level of  real economic growth.
