This paper contrasts empirically four leading models of inflation dynamics - the accelerationist Phillips curve (APC), the new Keynesian Phillips curve (NKPC), the hybrid Phillips curve (HPC), and the sticky information Phillips curve (SIPC). We employ an encompassing Phillips curve...

This paper shows that a simple form of nonlinearity in the Phillips curve can explain why, following the Great Recession, inflation did not decrease as much as predicted by linear Phillips curves, a phenomenon known as the missing disinflation. We estimate a piecewise-linear specification and...

How does competition affect information acquisition of firms and thus the response of inflation and output to monetary policy shocks? This paper addresses these questions in a new dynamic general equilibrium model with both dynamic rational inattention and oligopolistic competition. In the...

Using a New Keynesian Phillips curve, we document the rapid and persistent increase in the natural rate of unemployment, 𝑢𝑡 ∗ , in the aftermath of the pandemic and characterize its implications for inflation dynamics. While the bulk of the inflation surge is attributed to temporary...

A.W.H. Phillips is little known to the economics profession today, except at the creator of the Phillips curve. Bollard's engaging biography tells the story of a provincial New Zealander and practical engineer, who emerges as a hero in World War II, and plots a spectacular rise from 3rd class...

Existing menu cost models, when parameterized to match the micro-price data, cannot reproduce the extent to which the fraction of price changes increases with inflation. In addition, in the presence of strategic complementarities, they predict implausibly large menu costs and misallocation. We...

We assess the stability of the unemployment gap parameter using linear dynamic Phillips curve models for the United States. In this study, we allow the unemployment gap parameter to be time-varying such that we can monitor the importance of the Phillips curve over time. We consider different...

A Phillips Curve (PC) framework is utilized to study the challenging post-1985 disinflation process in Israel. The estimated PC is stable and has forecasting power. Based on endogenous structural break tests we find that actual and expected inflation are co-breaking. We argue that the step-like...
