Estimation of a technology matrix from a domestic coefficients matrix and a row of intermediate imports in input-output analysis

This paper suggests several methods of estimating a technology matrix from a domestic transactions matrix, and a row vector of imports into each sector. The performance of the proposed techniques is assessed on the basis of tests using data on a large number of countries, for which both domestic and technology matrices exist. The best method is subsequently used to generate estimates of technology matrices for countries where such information has not previously been available, and as an illustration of a possible application of such estimates, a brief international comparison of production structures is attempted.
