Analysis of changes in the industrial composition of economic activity (structural change) is important for informed policy making. Such analysis can best be undertaken using a computable general equilibrium (CGE) model. CGE models recognize links among industries arising from their roles as consumers of one another's products and from their competition for the economy's resources. In this paper, a detailed CGE model of the Philippines is employed to assess structural and technological change in Philippine agriculture during the period 1985 to 1992. The model estimates of technological change and other unobservable variables are used to explain structural change in Philipine agriculture and other sectors of the Philippine economy. The macroeconomic effects of this change are also discussed.
