| Abstract: | This article investigates the impact of different development scenarios on optimal investment strategy and economy of Sri Lanka and studies the potential of applying control theory techniques to economic planning. The multisectoral dynamic planning model is formulated as a linear quadratic tracking problem. Targets to be tracked define the development strategies: economic growth, trade deficit reduction, food self-sufficiency, and balanced growth. Besides providing insights into these strategies, empirical results show that the difficulty in setting inequality constraints and ensuring nonnegative solutions could undermine the linear tracking optimal control technique for development planning. |
