The Problem. Dynamic Programming: An overview Russell Cooper February 14, 2001 1 Overview The mathematical theory of dynamic programming as a means of solving dynamic optimization problems dates to the early contributions of Bellman [1957] and Bertsekas [1976]. We then study the properties of the resulting dynamic systems. Introduction to Dynamic Programming. Markov Decision Processes (MDP’s) and the Theory of Dynamic Programming 2.1 Definitions of MDP’s, DDP’s, and CDP’s 2.2 Bellman’s Equation, Contraction Mappings, and Blackwell’s Theorem However, some times there are subtle issues. endstream More readily applicable material will follow in later sessions. %���� Course Outline I Math for Dynamic Programming I I Math for Dynamic Programming II I Stability of dynamic system I Search and matching, a little stochastic dynamic programming Main reference book: Recursive methods in economic dynamics by Stokey and Lucas(SL) Solutions manual by Irigoyen and Rossi-Hansberg(IRH) We will focus on the Bellman approach and develop the Hamiltonian in both a deterministic and stochastic setting.

Usually, economics of the problem provides natural choices. The purpose of this chapter is to provide an introduction to the subject of dynamic optimization theory which should be particularly useful in economic applications.

Dynamic Programming, 1957. 1 Mathematical economics Why describe the world with mathematical models, rather than use verbal theory and logic? Notes on Dynamic Optimization D. Pinheiro∗ CEMAPRE, ISEG Universidade T´ecnica de Lisboa Rua do Quelhas 6, 1200-781 Lisboa Portugal October 15, 2011 Abstract The aim of this lecture notes is to provide a self-contained introduction to the subject of “Dynamic Optimization” for the MSc course on “Mathematical Economics”, part of the MSc In contrast to linear programming, there does not exist a standard mathematical for-mulation of “the” dynamic programming problem.

Dynamic programming is one of the most fundamental building blocks of modern macroeconomics. (1989) Recursive Methods in Economic Dynamics. The language instruction is Julia . It provides a systematic procedure for determining the optimal com-bination of decisions. Bellman Equations and Dynamic Programming Introduction to Reinforcement Learning. Stochastic Euler equations. Dynamic Programming in Economics is an outgrowth of a course intended for students in the first year PhD program and for researchers in Macroeconomics Dynamics. The method was developed by Richard Bellman in the 1950s and has found applications in numerous fields, from aerospace engineering to economics.. Dynamic Programming & Optimal Control Advanced Macroeconomics Ph.D. 11.1 AN ELEMENTARY EXAMPLE In order to introduce the dynamic-programming approach to solving multistage problems, in this section we analyze a simple example. A famous early reference is: Richard Bellman. economics: maximizing wages for the worker, and maximizing returns as an investor. Later we will look at full equilibrium problems. We assume throughout that time is discrete, since it … Dynamic Programming The method of dynamic programming is analagous, but different from optimal control in that optimal control uses continuous time while dynamic programming uses discrete time. We assume throughout that time is discrete, since it … Recall the general set-up of an optimal control model (we take the Cass-Koopmans growth model as an example): max u(c(t))e-rtdt & O.C. It gives us the tools and techniques to analyse (usually numerically but often analytically) a whole class of models in which the problems faced by economic agents have a recursive nature. where xt∈X⊂RKfor some K≥1.In many economic applications, we will have K=1,sothatxt∈R.
