An estimation of a price index that is immune to some of the weighting biases that can hinder the use of the Consumer Price Index as a reliable measure of inflation.

A reevaluation of the evidence of seasonality in prices, finding that seasonal price movements have become more prominent in the relatively stable inflation environment that has prevailed since 1982, and that the amount of seasonality differs greatly by item, making it difficult to generalize...

This paper investigates the use of trimmed-mean estimators and time-series averaging as techniques for improving the signal-to-noise ratio in high-frequency price data. We show that trimmed-mean estimators substantially increase the efficiency of the aggregate estimator compared to the more...

This paper reconsiders the empirical evidence connecting inflation to its higher-order moments. In particular, we examine the statistical properties of the observed positive correlation between the sample mean and the sample cross-sectional skewness of price changes. This correlation has...
