Accounts are also constructed at the level of the three major sectors (agriculture, industry
and services). Again, they are based on the estimates of GDP and the net capital stock from the
NESDB and employment estimates from the labor force survey. However, in the case of
agriculture, the calculation of the factor shares is extreme because employment is dominated by
the self-employed and unpaid family workers, but their income is assigned to capital. The labor
share averages only 11 percent, while that of capital is 85 percent. As a result, increases in
capital account for 114 percent of output growth and changes in the residual of TFP are negative.
There is not net growth of employment in agriculture. The accounts for industry and services
also indicate a dominant role for the capital factor because its income share is in excess of 60
percent in each case. Improvements in TFP remain positive in the industry sector, but they are
consistently negative for services.
