Abstract
In this paper the format of a Social Accounting Matrix (SAM) for use as a database for the Computable General Equilibrium (CGE) modelling of agricultural policy reform in South Africa is detailed. It is shown that the published South African SAMs impose limitations upon their suitability as databases for CGE models, but that they can be readily modified. An additional benefit of a SAM is its use as a framework for the specification of the behavioural relationships necessary to the development of a model. Finally, a Macro SAM for 1993 is reported and the proposed disaggregation of the agricultural sector is identified.
Hierdie referaat verskaf 'n volledige oorsig van dieformaat van 'n Sosiale Rekeninge Matriks (SAM) vir aanwending as 'n databasis vir 'n Algemene Ewewigsmodel (CGE) vir die modellering van landboubeleidshervorming in Suid-Afrika. Daar word aangetoon dat gepubliseerde SAMs van Suid-Afrika beperkings het en nie geskik is vir aanwending in 'n CGE model nie. Dit kan egter met enkele modifikasies reg gestel word. Die SAM het die bykomende voordeel dat die SAM raamwerk gebruik kan word om verwantskappe te spesifiseer wat noodsaaklik is vir die ontwikkeling van 'n model. 'n Makro SAM vir 1993 word beskryfen verder word die voorgestelde disaggregasie van die landbou geïdentifiseer.
