| Research Abstract |
In this study we present a theoretical framework to estimate degree of scale economy in household consumption, and estimate the resulting model from the Japanese data sets. We specify an indirect utility function that capture the relationship between household characteristics and consumption, and derive a demand system. We estimate the system parameters from the Japanese data sets in both aggregated and individual forms. The estimation results enable us to evaluate households’ real income level which reflects the effects of demographic characteristics, and to evaluate how real income distribution and economy of scale changed in the past.
