The Dual Stickiness Model and Inflation Dynamics in Spain

Abstract

We estimate a model that integrates sticky prices and sticky information using Spanish data following Dupor et. al (2008). The model yields three empircal facts: a-) the frequency of price changes (around one year), b-) the firm's report that sticky information is no too important for nominal rigidities and c-) the inflation's persistence, the latter with more microfoundations than the Hybrid Model. We found that both types of stickiness are present in Spain, but the most important is the stickiness in prices.Sticky Prices; Sticky Information; Spain; Inflation Dynamics
