ESTIMATION ERROR IN SECTORAL EMPLOYMENT REQUIREMENTS IN THE ABSENCE OF A DOMESTIC COEFFICIENTS MATRIX IN THE INPUT-OUTPUT ANALYSIS

The objective of the paper is to develop various estimation methods for allocating imports according to their end-use and to make use of the derived domestic transactions for the estimation of gross domestic output and employment by sectors. The standard design in the construction of input-output tables is to provide imports of a sector in the form of a column. These imports are not allocated according to their final use and therefore, total intermediate inputs consist of both domestic and imported inputs. The input-output tables for 12 European countries distinguish three types of transactions: (a) domestically produced inputs; (b) imported inputs; and (c) total inputs. We have made use of these tables assuming that the information on import allocation by end-use and domestically produced and imported inputs separately are not available. The allocations of imports are made under various assumptions and a comparison is made of employment based on artificially generated domestic coefficients with employment based on actual coefficients. The sectors are ranked on the basis of both sets of results. In addition, the ratio of indirect to direct employment for the estimators and actual is derived. The sectors are ranked and the rank correlations between alternative estimators and actual are calculated. Although the ratios differ markedly from method to method, the ranks do not alter.
