Decomposing The Changes Of The Divisia Price Index: Application To Inflation In The Philippines, Tomoki Fujii

We decompose the logarithmic change in the Divisia price index into the pure price, substitution, and preference effects, although the latter two effects are hard to distinguish in practice. This decomposition allows us to identify the incidence and contributing factors of inflation. In the Philippines, we find that the preference effect is much smaller than the pure price effect in all provinces. We also find that rich deciles have experienced a higher inflation than poor deciles between 1988 and 2006. However, the gap in the standards of living has actually widened because poor deciles lagged behind in consumption growth.

We propose a method to decompose the logarithmic change of the Divisia price index into the pure price effect, the preference effect and the substitution effect. Our empirical results in the Philippines shows the effects of preference change on the Divisia price index are heterogeneous but positive across all regions and income deciles. However, they are dominated by the pure price effect.
