Resum:

In economic literature, information deficiencies and computational complexities have
traditionally been solved through the aggregation of agents and institutions. In inputoutput
modelling, researchers have been interested in the aggregation problem since the
beginning of 1950s. Extending the conventional input-output aggregation approach to
the social accounting matrix (SAM) models may help to identify the effects caused by
the information problems and data deficiencies that usually appear in the SAM
framework. This paper develops the theory of aggregation and applies it to the social
accounting matrix model of multipliers. First, we define the concept of linear
aggregation in a SAM database context. Second, we define the aggregated partitioned
matrices of multipliers which are characteristic of the SAM approach. Third, we extend
the analysis to other related concepts, such as aggregation bias and consistency in
aggregation. Finally, we provide an illustrative example that shows the effects of
aggregating a social accounting matrix model. |
