The goal of this paper is to theoretically and empirically
demonstrate the consequences of different imputation methods using
recent data from the International Price Program. We suppose that
prices are missing due to random or erratic reporting. We consider
three different imputation methods: carry-forward, which just
assumes that the missing price is the same as in the previous
period; cell-mean, which imputes the missing price using either the
short-term or long-term index for related commodities; and linear
interpolation, which uses the last and next observations for the
item to linearly interpolate. Certain hybrid techniques, combining
either carry-forward or cell-mean with linear interpolation, are
also considered.
