Outline of Final Research Achievements

The first achievement is to summarize the characteristics of government statistics and Japanese household surveys. The basic information for each survey was reviewed and consistency among similar surveys were checked. The results revealed that there are problems associated with sample selection biases; ambiguous definitions; and measurement errors. The second achievement is that we constructed data that provide a comprehensive picture of household behavior with addressing statistical problems mentioned above. The data show that the decline in the national savings rate cannot be fully explained by the population aging. Third, we prepared for the construction of data that would take advantage of the development of information and communication technology. A pilot study was conducted and a new research project was launched.

Academic Significance and Societal Importance of the Research Achievements

家計行動を多面的に把握することは、日本経済・社会の現状を把握する上で不可欠である。これまでの政府統計では、統計ごとにカバー範囲が異なっており、相互に整合的に利用することは容易ではなかった。本課題によって、政府統計がもつ課題を明らかにし、さらに補正方法を提案することでより適切なデータの構築に成功している。学術的にも政策的にも、今後の議論の基礎となる貢献である。
