How do changes in aggregate volatility alter the impulse response of output to monetary policy? To analyze this question, I study whether individual prices in Producer Price Index micro data are more likely to move in the same direction when aggregate volatility is high, which would increase...

Cross-sectional variation in micro data can be used to empirically evaluate sufficient statistics for the response of aggregate variables to policy shocks of interest. We demonstrate an easy-to-use approach through a detailed example. We evaluate the sufficiency of micro pricing moments for the...

This paper evaluates the informativeness of eight micro pricing moments for monetary non-neutrality. Frequency of price changes is the only robustly informative moment. The ratio of kurtosis over frequency is significant only because of frequency, and insignificant when non-pricing moments are...
