Economics working papers from Vancouver School of Economics

Abstract: A new source of potential bias in the Consumer Price Index (CPI) is described. We find that unit value (average) prices, commonly used for construction of the CPI should be constructed over the same period as the index to be constructed, rather than over an incomplete sub-period. The latter approach can lead to an upward bias in the CPI.
