Heterogeneous firm dynamics and price setting behavior

Empirical studies in reset price inflation find it difficult to justify volatile actual inflation while maintaining the volatility of reset price inflation at a reasonably low level. Firm's price setting behavior plays an important role in generating volatility of inflation. This paper employs an innovative approach by introducing firm heterogeneity into a micro-founded Calvo-type partial equilibrium model to study price setting behavior and demonstrates that granularity is a potential solution to the reset price inflation puzzle. Granular effects are also shown to be robust under different sets of parameter values.
