During the period of 1987-1995, Payments to labour was lowest in 1987 and highest in 1991. The surplus composed of rental, interest, and profit gains always has the highest share.

The studies will continue to be reported in the earliest possible time with more detail. Further division of surplus into rental, interest and profit incomes is among the objectives of the study.
