Advanced Macroeconomics: Recursive Methods


PRAT Julien

Department: Economics


Recursive methods have become the cornerstone of dynamic macroeconomics. The objective of this course is to offer an intuitive yet rigorous introduction to recursive tools and their applications in macroeconomics. We will illustrate the economic implications of each concept by studying a series of classic papers. In particular, we will discuss how recursive methods have been used to analyze asset pricing, economic growth, optimal taxation and insurance, credible government policies, and unemployment.


Part I: Basic Approach
Chapter 1: From the Calculus of Variations to the Hamilton-Jacobi-Bellman Equation
Chapter 2: Dynamic Programming
- Application: Optimal Growth

Part II: Dynamic Programming under Uncertainty
Chapter 3: Markov Chains
- Application: Asset Pricing
Chapter 4: Convergence of Markov Processes
- Application: Equilibrium Search Unemployment
Chapter 5: Bayesian Learning
- Applications: Jovanovic’s Matching Model, Reputation

Part III: Dynamic Programming “Squared”
Chapter 6: Dynamic Programming with Commitment
- Application: Optimal Capital Tax
Chapter 7: Dynamic Participation Constraints
- Applications: Labor Contracts, Credible Fiscal-Monetary Policies
Chapter 8: Dynamic Incentive Constraints
- Application: New Dynamic Public Finance


We will cover a series of papers whose list will be communicated during the course. Most of the material will be contained in the slides, but students are encouraged to also consult the following books.
