The economy starts at A, where the short-run Phillips curve SRPC₁ crosses the long-run Phillips curve (LRPC) at the natural rate uₙ, with inflation at π₁. It moves up along SRPC₁ to B, where unemployment has fallen to u₁ and inflation has risen to π₂. The SRPC then shifts up to SRPC₂, and the economy moves across to C on the LRPC, back at uₙ with inflation at π₂.
