Supply shocks eliminate the Phillips curve

We will look at the situations of the United States and the euro zone. In both cases, the usual relationship between the unemployment rate and wage growth has weakened considerably in the recent period. One natural explanation of the virtual disappearance of the Phillips curve is the appearance of positive supply shocks. A positive supply shock leads to both a decline in inflation and a rise in employment, which cancels out the usual Phillips curve effect. In particular, such a positive supply shock may have resulted from: Corporate tax cuts; The rise in the participation rate; The fall in energy prices. But negative supply shocks also eliminate the Phillips curve. In particular, such a negative supply shock may have resulted from: The inability to produce (due to the lockdowns and disruption of production chains); The rise in unit labour costs due to the fall in productivity under the effect of the new public health rules.
