| Abstract: | After defining economic activity the author lists the chief types of non–market economic activities for which he has prepared estimates for the United States 1929–1973, and briefly describes his methodology and data sources. Some major findings are: (1) As of 1973 GNP adjusted to include the additional imputations was 63.5 percent larger than the official estimate. (2) At least since 1929 imputed values have grown faster than official GNP, especially when both are measured in terms of real factor costs. (3) The personal sector comprises a far larger portion of the national economy-almost one-third—when account is taken of imputed labor and property compensation, and its relative importance has grown. (4) Gross government product is more than 60 percent higher when the imputed rental value of public property is added to the compensation of general government employees. (5) Reflecting the relative growth of non-business wealth, imputed property income has risen much faster than monetized property income. This has mitigated the decline in the property share of expanded gross national income compared with its share in the official estimates. |
