Abstract

In 2002, the US Bureau of Labor Statistics (BLS) introduced a supplemental C-CPI-U employing a superlative formula to provide a closer approximation to a cost-of-living index (COLI). This paper focuses on whether the BLS can improve upon the headline CPI-U’s current biennial weight update process, thereby reducing the CPI-U’s growth rate and bringing the index closer to the C-CPI-U.
