Abstract

We revisit U.S. trend inflation dynamics since the 1960s by estimating a nonlinear, nonstationary Markov-switching New Keynesian model in which trend inflation evolves as a latent Markov process. Our estimation (i) confirms the Volcker disinflation as a regime shift from high to mid-level trend inflation between 1980 and 1987; (ii) shows that trend inflation remained stable around 2.8% during the Great Moderation and beyond, despite major disruptions such as the Global Financial Crisis and the COVID-19 pandemic; and (iii) identifies a persistent hawkish monetary policy regime after 1982, with temporary weakening during periods of policy rate reductions at the zero lower bound—while inflation expectations remained well anchored.
