In the real world, the theory of economic faces many obstacles in its analyses and interpretations. One of these problems is overlapping relationships between specific variables and difficulty of determining perfect formulation which contain all possible effect. Traditional statistics tools like...

We present a method of calculating the maximal eigenvalue of an indecomposable nonnegative matrix, which is based on ideas of geometric programming. In addition to that, we obtain estimates for elements of an indecomposable nonnegative matrix by its spectral radius. The results make it possible...

The capacity of input-output tables to reflect the structural peculiarities of an economy and to forecast, on this basis, its evolution, depends essentially on the characteristics of the matrix A matrix of I-O (or technical) coefficients. However, the temporal behaviour of these coefficients is...

Many economic models (e.g., computable general equilibrium models, econometric input-output models) revolve around a matrix of technical coefficients. However, these matrices can be estimated only once every 5 years as long as they are calculated from input-output tables and these are only...
