The study examines the sensitivity of input-output calculations. It analyses the accuracy of the eigenvalues of matrices when calculating the Hungarian branch multiplier for the year 2000. Attention needs paying to the continual fluctuation of the economy and its state of disequilibrium. The author starts from the eigenvalues because these can be established most accurately under such conditions. He also shows how use of the Leontief inverse can reduce error in initial data, as diagnosis of it is dominant and the matrix well conditioned. There is further analysis of error-correcting, compensating features of some other recommended methods of calculation.
