Abstract
Preference of goods in household controls consumption of goods, and consequently influences supply and demand equilibrium of the country goods market. Also and more important, it determines the quantity and quality of households wastes. In order to project future waste amount generated by households, the abovemechanism must be taken into account. In this study, we developed a model of household waste generation based on Becker's household production approach. The model can consider the impact of lifestyle change on household generation. Also, it was applied to forecast Japanese household waste generation in near future.
