The authors have considered the forward dynamics approach using the single-shooting approach with the Euler method as integration method, and the inverse-dynamic approach using the polynomial approximation and the combined polynomial-Fourier series which is used by [25]. In Chapter 3 we developed the theory of optimisation, arguing that it provided the basis for a wide variety of economic models. The models used for studying such motions are complex, and so it takes a long time to run a dynamic optimization (days to weeks). Download Full PDF Package. 16 0 obj << or.

Dynamic Optimization Problems 1.1 Deriving rst-order conditions: Certainty case We start with an optimizing problem for an economic agent who has to decide each period how to allocate his resources between consumption commodities, which provide instantaneous utility, and capital commodities, which provide production in the next period. Dynamic optimization is potentially more powerful than static optimization for two reasons. The type of model analysed in that chapter involved agents making choices concerning the values of a variable at an instant in time.Many choices, however, involve the time-paths of variables from now, when the choice is made, until some time in the future. We will start by looking at the case in which time is discrete (sometimes called Dynamic Optimization - KamienSchwartz.
