Markov processes and dynamic programming are key tools to solve dynamic economic problems and can be applied for stochastic growth models, industrial organization and structural labor economics. We start by covering deterministic and stochastic dynamic optimization using dynamic programming analysis. Macroeconomics Lecture 8: dynamic programming methods, part six Chris Edmond 1st Semester 2019 1.

It was shown in Handout #6 that we can derive the Euler Find the savings rate and plot it. Throughout the course, we will emphasize the need to confront theoretical results to empirical evidence, and we discuss methods to compare model and data. The presentations of discrete-time dynamic programming and of Markov processes are authoritative. We then discuss how these methods have been applied to some canonical examples in macroeconomics, varying from sequential equilibria of dynamic nonoptimal economies to time-consistent policies or policy games.

"The term dynamic programming was originally used in the 1940s by Richard Bellman to describe the process of solving problems where one needs to nd the best decisions one after another. In our lecture, we will consider … Modern dynamic macroeconomics is fully grounded on microeconomics and general equilibrium theory. The agent uses an endogenously simplied, or \sparse," model of the world and the conse- quences of his actions and acts according to a behavioral Bellman equation.
