Abstract

With this paper we present a preliminary version of the first and the third quadrants of the input-output matrix for Alentejo, a Portuguese region through the regionalization of the input-output national table, for the year 2008. As it is well known the input-output (IO) model is particularly appropriate for the analysis of the effects of demand on supply (possibly in territorial/regional terms). As such, from the descriptive point of view, the IO model is useful for the analysis of explanatory factors of (regional) growth. Moreover, from a decision-making point of view it allows to support (regional) decision making in order to change (in the most favorable possible way) the (regional) production structure. This is particularly important for the fragile region of Alentejo where such instruments are scarce. Furthermore, the second quadrant, from which demand effects can be considered and extended to third quadrant, where a proper quantification of inter-regional imports is to be considered, complete the table. From the production perspective, our preliminary results suggest weak inter-sectors relations in the Alentejo region. In particular, more than 75% of the indirect effects are below 0,05. Furthermore, tobacco, food, beverages, crude refineries, fishing & aquaculture, clothing and agriculture sectors have the most relevant type II multipliers. However, only clothing and beverages have higher aggregate indirect effects over all other industries as a result of an increase of one euro on their final demands. Regarding type I multipliers, our results suggests a different picture. Forestry, tobacco, leather, beverages, among other have important direct and indirect effect. These results have important policy implications in this fragile region.
