• The objective of the study is to compose a disaggregated trade balance model for South Africa. The trade balance is calculated by estimating the imports and exports of merchandise in regression equations, which are disaggregated according to the Standard International Trade Classification. The regressions are preceded by an empirical investigation into the structure of South Africa's foreign trade as well as a review of the related economic theory, in order to compose economically justifiable regression equations. The equations are postulated as demand functions and are estimated in its linear and log-linear form, while lag structures are also employed. These different models are simulated and the results compared with a view to select the most acceptable package of equations to include in the model. It is notable that the equations underlying the model mainly employ an income/expenditure and relative price variable to explain the movements in foreign trade.
