Abstract

This paper conducts a comprehensive review of the relationship between inflation and unemployment in the U.S. as described by the Phillips curve in a New Keynesian framework and investigates whether this relationship has changed systematically over time. We also aim to identify possible explanations for these changes. Three different hypotheses are discussed to assess whether they are consistent with more recent developments, such as the evolution of inflation expectations, the impact of globalization, and possible nonlinearities in the functional shape of the Phillips curve. We find that the relationship between inflation and unemployment has weakened since the 1980s and especially during the Covid-19 pandemic due to forces of globalization and better anchored inflation expectations resulting from more credible monetary policy. This has led to question of whether the Phillips curve is outdated. We conclude with the implications of these findings for the conduct of monetary policy.
