Abstract
The variability in technical coefficients calculated based on the input-output tables published by the Czech Statistical Office for the period 1995 to 2010 is examined in the present paper. The low variability of coefficients is a prerequisite for their applicability in macroeconomic forecasts and analysis. The paper progressively deals with the meaning of technical coefficients, the method of their calculation, and the characteristics of variability. It was found that the variability of coefficients is high and, therefore, that the technical coefficients, with few exceptions, are unsuitable for making predictions.
