Some Lectures on Macroeconomics

We present some theoretical frameworks used in macroeconomics, mainly economic growth. Our goal is not to provide a unified model but rather to present simplified versions of models in the classic academic articles to help students familiarize with theoretical models used in macroeconomics and taught in most graduate programs. In each section, we explain our objective and motivation illustrated by empirical data. We then build a theoretical model allowing us to address our question. We hope that this lecture would be useful for readers (not necessarily having a good background in economics) who want to follow the graduate programs in economics. However, readers should have a background in finite-dimensional optimization and discrete-time dynamical systems.
