In the following, two simple examples are given. Dynamic programming Martin Ellison 1Motivation Dynamic programming is one of the most fundamental building blocks of modern macroeconomics. Most are single agent problems that take the activities of other agents as given. We then study the properties of the resulting dynamic systems. Sign up to join this community 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. Economics Stack Exchange is a question and answer site for those who study, teach, research and apply economics and econometrics. recursive 1. Each of the subproblem solutions is indexed in some way, typically based on the values of its input parameters, so as to facilitate its lookup. Dynamic Programming is a method for solving a complex problem by breaking it down into a collection of simpler subproblems, solving each of those subproblems just once, and storing their solutions using a memory-based data structure (array, map,etc). Numerical Dynamic Programming in Economics John Rust Yale University Contents 1 1. Introduction 2. The unifying theme of this course is best captured by the title of our main reference book: "Recursive Methods in Economic Dynamics". dynamic programming was originated by American mathematician Richard ... economics: maximizing wages for the worker, and maximizing returns as an ... introduce the complicated mathematics of dynamic programming, we consider the simple example of … Tree DP Example Problem: given a tree, color nodes black as many as possible without coloring two adjacent nodes Subproblems: – First, we arbitrarily decide the root node r – B v: the optimal solution for a subtree having v as the root, where we color v black – W v: the optimal solution for a subtree having v as the root, where we don’t color v – Answer is max{B So before we start, let’s think about optimization. The essence of dynamic programming problems is to trade off current rewards vs favorable positioning of the future state (modulo randomness). The first example is a finite horizon dynamic asset allocation problem arising in finance, and the second is an infinite horizon deterministic ... optimal growth model arising in economics. Later we will look at full equilibrium problems. • Course emphasizes methodological techniques and illustrates them through applications. It only takes a minute to sign up. Dynamic Programming¶ This section of the course contains foundational models for dynamic economic modeling. Examples: consuming today vs saving and accumulating assets ; accepting a job offer today vs seeking a better one in the future ; … 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 We start by covering deterministic and stochastic dynamic optimization using dynamic programming analysis.
