Rumors of the death of the Phillips curve appear to have been greatly
exaggerated. In fact, the Phillips curve is alive and well, and living
in a good number of (although certainly not all) widely used macroeco
nometric models. The author takes the view that the primary reason for
its longevity is that the Phillips curve has been an extremely robust
empirical relationship, showing little or no sign of instability over
the past 35 years. He examines an array of empirical evidence and fin
ds that the Phillips curve has exhibited remarkable stability, even ac
ross data for what must be the most dramatic shift in monetary policy
regime since World War II. To outward appearances, at least, the Phill
ips curve is as structural a relationship as macroeconomists have ever
had at their disposal.
