The study looked at how inflation, output, and unemployment behave in Sub-Saharan Africa countries. In the short term, the Phillips curve and Okun's law predictions hold true. But in the long term, the Okun's law effect weakens and becomes positive, while the Phillips curve shifts towards the New Keynesian Phillips Curve with a negative relationship. This supports the idea of a temporary trade-off between inflation and unemployment, but not a permanent one. The relationship between output and unemployment suggests that long-term growth in Sub-Saharan Africa was not inclusive or pro-poor.
