| Outline of Final Research Achievements |
We applied an exact matching technique to assess the accuracy of two corporate surveys, namely, one provided by the Ministry of Finance (MOF), and the other provided by the Statistics Bureau of the Ministry of Internal Affairs and Communications (MIC). There are considerable differences between MOF and MIC surveys. Statisticians at the MIC and MOF have tried to determine the causes of differences, but they have yet to be successful.
We compared these two important surveys and obtained new findings concerning the reliability of official statistics of firms and establishments. Specifically, we derived the following: (1) The effect of the difference in the number of companies is relatively small. (2) A tentative conclusion is that although the difference in the numbers of corporations is not negligible, aggregated statistics of corporations, such as sales and numbers of employees, are not seriously biased. Thus,both MOF and MIC surveys are reasonably reliable.
