This paper reviews a substantial range of empirical evidence on whether the Phillips curve is dead, i.e. that its slope has flattened to zero. National data going back to the 1950s and 60s yield strong evidence of negative slopes and significant nonlinearity in those slopes, with slopes much...

This paper first outlines the key stylized facts about changes in inflation dynamics in recent years: 1) inflation persistence has declined, 2) the Phillips curve has flattened, and 3) inflation has become less responsive to other shocks. These changes in inflation dynamics are interpreted as...

Recent theorizing with business cycle models which incorporate features of the Friedman-Phelps natural rate model along with rational expectations lead to the following policy conclusions.
