Abstract
En este trabajo utilizando datos de países europeos, se revisa cómo influye la
reducción de una tabla input-output en los multiplicadores y encadenamientos
de las ramas que no se unen, con ello se responde la hipótesis: “a mayor nivel
de agregación los distintos encadenamientos de las ramas no agrupadas son
afectados en forma sistemática y definida”.
Se concluye que los resultados dependen del peso relativo que tengan
los coeficientes que no se unen respecto a los unidos, así, los multiplicadores
o encadenamientos pueden presentar efectos acumulativos, oscilantes o
decrecientes.
European countries data has been reviewed, in this paper, in order to review how the aggregation of an Input-Output Table influences on the multipliers and linkages of the branches that do not join themselves. These facts let us that the following hypothesis were answered: “A higher level of aggregation, the different linkages of the non put into branches are affected in a systematic and defined way”. It is concluded that the results depend on the relative weight of the non linked coefficients regarding to the linked one, therefore the multipliers or linkages can present accumulative, oscillating or diminishing effects.
