Saeed Zaman on disaggregating CPI measures
What is the optimal level of disaggregation for median and trimmed-mean CPI?
Saeed Zaman is a Senior Research Economist at the Federal Reserve Bank of Cleveland. He sat down for an interview at the 2025 AEA poster session to talk about the optimal level of disaggregation for median and trimmed-mean CPI. He found that more disaggregation does not always improve the ability of the median and trimmed-mean CPI to track the medium-term trend in CPI inflation.
