Quarterly estimates of expenditures on gross domestic product and their stability

The article is engaged in the improvement of quarterly information on the gross domestic product by type of expenditures from the first expectations to final data. It concludes that the first estimate of GDP is under-estimated. This underestimation is caused by underestimation of the final households consumption expenditures and of the gross fixed capital formation. At the balancing process, when the above-mentioned items of expenditures are under-estimated, the surplus of resources side could be allocated to the change in stock of inventories item. Thus this item contains the discrepancy between the resources side and expenditures side of GDP and is disqualified from its role in business-cycle analysis. Differences of biases in constant prices data and in current prices data are also stated.
