Factor Income shares. The most questionable aspect of the growth accounts revolves around the computation of the appropriate income shares to serve as weights in the aggregation of the capital and labor inputs. Because the total income of the self-employed (employers, own account, and unpaid family workers) equals or exceeds that of wage earners, it is critical to obtain a reasonable distribution of their income between the labor and capital components. The most reasonable method is to increase the estimate of employee compensation in the national accounts by the ratio of total employment to employees.
