315201 Intertemporal Optimization in Economics and Business (V) (WiSe 2004/2005)

Dynamic optimization (or intertemporal optimization) plays a more and more important role in economics and business studies, since economic agents may consider not only what happens today but also what may happen in the future. A dynamic optimization problem poses the question of what is the optimal magnitude of a choice variable in each period of time within the planning period (discrete-time case) or at each point of time in a given time interval (continuous-time case). In this course, the techniques for optimization in intertemporal models -- discrete- or continuous-time, deterministic or stochastic -- will be introduced. Applications of these techniques in the field of economics and business will also be shown.
