It has been shown that extending the Calvo model to account for the heterogeneity in price stickiness suggested by the micro-evidence significantly improves the performance of the model. In the new model, price-changing firms are chosen disproportionately from sectors with more flexible prices....

During the Great Recession, despite the large fall in output, inflation did not fall much. This is known as the missing deflation puzzle. In this paper, we develop and estimate a New Keynesian Dynamic Stochastic General Equilibrium model to provide an explanation for the puzzle. The new model...

This paper aims to explore the impact of rising uncertainty on prices using micro-data on prices and multi-sector new Keynesian models. We identify diverse price responses to increasing macroeconomic uncertainty: goods with relatively flexible prices experience a decline due to lower demand...
