Abstract

This article develops a novel nonparametric time-varying auto-regressive distributed lag model to estimate the persistence of inflation. The local linear estimation method is used to estimate the coefficients. Empirically, the persistence of the inflation process in the United States declined prior to the global financial crisis (GFC) of 2007–2009, but then rebounded strongly until 2022.
