The study looks at how inflation and unemployment affect economic growth in Sudan. It explores the idea of a trade-off between wage inflation and unemployment, known as the Phillips Curve. The researchers investigate whether this relationship holds true in African developing countries like Sudan. They find that in the short run, there may be a trade-off between inflation and unemployment, but in the long run, this relationship may not exist. This suggests that the impact of inflation and unemployment on economic growth is a complex issue that policymakers need to consider carefully.
