ABSTRACT
The regular calculation and increasing reliability of national income data since the end of the war have created new possibilities for the analysis of economic relationships. Time series and ratios between important subcategories-which were not available before-can now be constructed. But difficulties remain because the standardized OECD scheme of national accounts does not always contain those disaggregations which are required for some problems and the additional statistics needed are not easily obtained. This leads frequently to discussions which use a few significant key data without giving sufficient consideration to the consequences this may have for the interpretation of the results. Some of these problems arising in connection with the income account and particularly with the share of wages and salaries in national income are the subject of this paper.
