Indexation theories have become standard for inflation persistence in DSGE models (Smets and Wouters (2003, 2007)). However, these theories overlook an important stylized fact of U.S. business cycles: high fluctuations in the first difference of inflation. I find that this pattern can be captured by adjustment costs precisely from the first difference of inflation (Pesaran (1991) labels this difference as a "speed change"). I estimate four DSGE models differing in their rigidity assumption and find that a framework with inflation-based adjustment costs has the highest probability to fit U.S. data.
