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...

The objective of this research is to present some accuracy measures associated to forecast intervals, taken into account the fact that in literature some specific accuracy indicators for this type of prediction have not been proposed yet. For the quarterly inflation rate provided by the National...

Pornind de la faptul ca colinearitatea genereaza distorsiuni atat ale valorilor estimate cat si ale testelor statistice, la inceputul prezentei lucrari sunt inventariate consecintele respectivelor distorsiuni si este construita o metoda de identificare a tipurilor de colinearitate, avandu-se in...

The main goal of the present work is to reveal the advantages of introducing the so-called structural coefficient (SC) in economic analysis. SC is defined as an indicator of the similarity between a given sectoral structure and another, which is admitted as a referential. Consequently, the paper...

Principalul scop al acestui studiu este să prezinte o tehnică de modelare care este regresia ortogonală sau modelul EIV cu erori-în-variabile şi posibilele aplicaţii în economie. Metodele de calcul şi principalele proprietăţi statistice ale estimatorilor sunt discutate. In partea...
