We construct an error correction mechanism to examine whether firms’ price adjustment is asymmetric as anticipated by Ball and Mankiw (1994). We have used monthly time series data on prices of 418 commodities, which constitute 97 percent of commodity price basket used in the construction of...

We propose a new methodology to construct core inflation which is, unlike other conventional methods, not based on ad hoc elimination/trimming of prices. The empirical results suggest that the proposed measure of core inflation is highly correlated with headline inflation and is noise free; hence...

The U-shaped relationship between inflation and price dispersion around nonzero inflation rate is due to the use of aggregate measure of relative price variability (RPV), which amounts to specification errors in a piecewise linear regression models. However, the true underlying relationship...

This study decomposes relative price variability into a component due to inflation and a component due to real factors. The empirical results for India suggest that real factors account for 55% and inflation accounts for 45% of the variability in relative price changes. The proportion of...

We propose a new methodology to construct core inflation which is, unlike other conventional methods, not based on ad hoc elimination/trimming of prices. The underlying inflation derived from our method is found to be a powerful leading indicator of headline inflation while other conventional...
