# Introduction to Modern Macroeconomics II, Fall 2019

## Summary

This is the second course in the macroeconomics part of the master program. This course has 3 modules. In the first part, we will review mathematical perquisites for solving dynamic problems, which is the case for most of macro problems. We introduce Bellman Equations and the **principle of optimality** and using fixed point theorems show how to use iteration methods to find the value function as well as policy function. Finally we will introduce neoclassical growth model.

Second part of the course focuses on the **economics of money, banking and financial markets**. It is very important to understand how financial markets work and how they may affect real economy.

The last part of this course is devoted to **monetary policy**. We will introduce quantity theory of money and will argue that almost always inflation is the result of rapid growth of the money supply. If time permits, we will also introduce transmission mechanisms of monetary policy.

## Interesting Readings

I recommend the following paper to my math enthusiast friends!

Partial differential equation models in macroeconomics by Ben Moll et. al.

Ben Moll has a very nice lecture about inequality and macro.
