IMF Working Papers

Why did US inflation rise over 2021-22 and why has it retreated since then? Ball, Leigh, and Mishra (2022), writing near the inflation peak, explained the rise with a framework in which inflation depends on three factors: long-term expectations; the tightness of the labor market as measured by the vacancy-to-unemployment (V/U) ratio; and large changes in relative prices in particular industries such as energy and autos. This paper finds that the same framework explains the retreat in inflation since our earlier work.
