Phillips Curve Flattening
Phillips curve flattening describes the weakening of the historical inverse link between unemployment and inflation, where low joblessness no longer reliably pushes inflation up.
In recent decades, falling unemployment in many economies produced surprisingly little inflation, suggesting the Phillips curve flattened. Globalisation, anchored inflation expectations and technology are cited causes.
A flat Phillips curve complicates central banking: policymakers can let employment run higher without immediate inflation, but it also means inflation, once unleashed (as post-pandemic), is harder to read from labour-market slack alone. The RBI weighs this when interpreting India's growth-inflation mix.
