Outline

In Recent Years Developments in Modeling and in Computational/Econometric Techniques Have Brought us to the Brink of the Point Where Dynamic General Equilibrium Theory Becomes Useful for Providing Practical, Quantitative Policy Advice. The Purpose of this Course is to Survey These Developments. The Course Grade Will be Based on Weekly Homeworks and a Take-home Final.

3. Solution Methods Based on Model Linearization.  

Linearization methods: Indeterminacy, Lack of Solution
