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.
Validation problems and technological change in an input‐output model
The problems of validation of an input‐output model for forecasting the effects of clothing imports on the textile and other industries in the Australian economy are described. These relate to incomplete data requiring estimators to complete a fundamental matrix and allowance for technological change from one previous time period to another. Although reasonable reconciliation was achieved between computed results and industry observations and data over the most recent historical periods for which data is available, the use of the method for forecasting requires allowance to be made for the inclusion of forecasted technological changes via endogenous variables or other means. The method described for the Australian study throws light on some important economic issues which required qualification during the period used for validation. It is operated on a desk top computer.
Input-Output Table for India 1963
The input-output table is a very convenient means of combining a huge mass of heterogeneous statistical data into a coherent whole such that the structural relationships underlying the economy can be analysed. The table has three constituents viz. intersectoral transactions; final demand vectors, and value added row.
