We use noncausal autoregressions to examine the persistence properties of quarterly U.S. consumer price inflation from … 1970:1.2012:2. These nonlinear models capture the autocorrelation structure of the inflation series as accurately as their … conventional causal counterparts, but they allow for persistence to depend on the size and sign of shocks to inflation as well as …

We propose a noncausal autoregressive model with time-varying parameters, and apply it to U.S. postwar inflation. The … model .fits the data well, and the results suggest that inflation persistence follows from future expectations. Persistence … curve indicate that current inflation also depends on past inflation although future expectations dominate. The implied …
