Sticky Information and Inflation Persistence: Evidence from U.S. Data


  • Benedetto Molinari

    () (Department of Economics, Universidad Pablo de Olavide)


This paper provides a novel single equation estimator of the Sticky Information Phillips Curve (SIPC), which permits to estimate the exact model without any approximation or truncation. In detail, information stickiness is estimated by employing a GMM estimator that matches the theoretical with the actual covariances between current inflation and the lagged exogenous shocks that affect firms’ pricing decisions, which are considered the moments that measure inflation persistence. The main result of the paper is to show that the SIPC model can match inflation persistence only at the cost of mispredicting the variance of inflation, which is a novel finding in the empirical literature on the SIPC.
