However, many constrained optimization problems in economics deal not only with the present, but with future time periods as well. In Chapter 3 we developed the theory of optimisation, arguing that it provided the basis for a wide variety of economic models.

First, because a time-dependent per-formance criterion can be posed, the goal of the motor task can be included in the formulation of the problem. 8 0 obj The classical calculus of variations, optimal control theory, and dynamic programming in its discrete form are explained in the usual Chiang fashion, with patience and thoroughness. Dynamic optimization is potentially more powerful than static optimization for two reasons. of dynamic optimization was formulated both as a discrete-time problem, and in alternative versions of the so-called reduced form model, by Radner (1967a), using dynamic programming methods, and by Gale (1967) and McKenzie (1968), using the methods of duality theory.
