We test the menu cost model of Ball and Mankiw (1994, 1995) on data from the inflation and deflation periods in Japan and Hong Kong. We calculate the moments of the distribution of price changes using a random split procedure to overcome the bias noted by Cecchetti and Bryan (1999). The key...

To appropriately model the observed slow response of real variables to nominal shocks, macroeconomic models augment nominal with real rigidities. One very popular way of modelling such a real rigidity is to assume a non-constant demand elasticity. While there has been conducted ample empirical...

This text proposes three adaptations related to disaggregations in the Brazilian National Consumer Price Index (IPCA) in order to provide relevant data for studies on inflation in disaggregated cuts, in monthly periodicity from August 1999 to September 2014. In the first, the compatibilization...

To model the observed slow response of aggregate real variables to nominal shocks, most macroeconomic models incorporate real rigidities in addition to nominal rigidities. One popular way of modelling such a real rigidity is to assume a non-constant demand elasticity. By using a homescan data...

This paper extends the New Keynesian model to allow for stochastic shifts in the monetary policy regime. Agents cannot observe the regime and use a Bayesian learning rule to make optimal inferences. Price setting is adapted to this environment: lagged expectations about monetary policy influence...

This paper examines the stability of balanced paths of expansion or contraction in closed macroeconomic models as typical cases of homogeneous dynamical systems. Examples of known two-dimensional deterministic and stochastic models are discussed. The appendix presents the mathematical tools and...

The price-setting behaviour of manufacturing plants is examined using a large panel of monthly surveyed plant- and product-specific prices. The sample shows a high frequency of zero changes, relatively small price changes, and a strong seasonal price-change pattern. The intermittent feature of...
