that such an index formula is prone to substitution bias. Therefore, also the terms of trade (ratio of export and import … price index) are likely to be distorted. The underlying substitution bias accumulates over time. The present paper … introduces a simple and transparent retrospective correction approach that removes the substitution bias and produces meaningful …

Trimmed-mean Personal Consumption Expenditure (PCE) inflation does not clearly dominate ex-food-and-energy PCE … inflation in real-time forecasting of headline PCE inflation. However, trimmed-mean inflation is the superior communications and … policy tool because it is a less-biased real-time estimator of headline inflation and because it more successfully filters …

Two such biases are the substitution bias and the quality adjustment bias. Most analyses of … substitution bias rest on the concept of the cost of living, positing that preferences are stable, homogeneous and homothetic …
