Recent exchanges in the literature on the identification and role of key sectors in national and regional economies have highlighted the difficulties of consensus regarding terminology, appropriate measurement as well as economic interpretation. In this paper, some new perspectives are advanced...

Using the input output tables constructed for Brazil (1959, 1970, 1975, 1980) and the 1985 Brazilian industrial census, this paper has 2 basic goals: 1) to make a study of how the Brazilian economy changed in the period 1960-1985; 2) to make suggestions of how the Brazilian economy could return to...

Attempts to identify key sectors in an economy with input output models have been a source of considerable debate. in this paper; several old and new approaches to the problem are evaluated with reference to the Brazilian economy using the input-output models for 1959, 1970 and 1975. Two...

Many applications require constraining arrays of numbers to controls in one or two dimensions. Example applications include survey estimates, disclosure avoidance, input-output tables, and population and other estimates and projections. If the results are allowed to take on any nonnegative...

Demographers and economists frequently encounter the problem of constraining matrices of mixed sign to controls of possibly mixed sign. The recently developed Generalized RAS (GRAS) algorithm is presented to solve these problems. The GRAS algorithm produces a unique solution that minimizes an...

The problem of constraining matrices of mixed sign to controls of possibly mixed sign arises in input-output matrices in economics and net migration in demography. The recently developed Generalized RAS (GRAS) algorithm is presented to solve these problems. The GRAS algorithm produces a unique...

In this work we present a methodology of multipliers decomposition (including an employment multiplier), for a regional economy as Andalusia using Social Accounting Matrices (SAM). These matrices are able to enlarge the information provided by the input-output analysis, because they complete the...
