Comparing new final-demand producer price indexes with other government price indexes

Analyses of the PPI for personal consumption and the CPI-U, the PPI for export goods and the IPP export index, and the PPI for final demand and the BEA price indexes for GDP and gross domestic purchases reveal that (1) the PPI for personal consumption and the CPI-U differ in scope and coverage, categorization, and other technical areas; (2) the PPI for export goods and the IPP export index are similar in scope, but differ because the IPP export index is constructed from actual export prices whereas the PPI for export goods uses commodity prices as proxies for export prices; and (3) the PPI for final demand and the BEA price indexes for GDP and for gross domestic purchases differ as a result of calculation formulas, coverage, and their respective treatments of government and international transactions.
