Syllabus

Objective

Introduction to classic developments in macroeconomics. Students will deepen their knowledge to formulate and solve stochastic dynamic economic models and apply these techniques to several substantive issues in consumption, asset pricing, business cycle theory, monetary economics, and labor economics. The subject will also cover dynamic models with heterogeneous households and will use these models to analyze a range of issues, including income and wealth inequality.

Lectures

1 and 2 - Equity Premium Puzzle

• Notes

• Code

• Readings:

  • Mehra, R., & Prescott, E. C. (1985). The equity premium: A puzzle. Journal of Monetary Economics, 15(2), 145-161.

3, 4, 5, and 6 - Incomplete Markets and Heterogeneous Agents in Steady State

• Notes: Huggett (1993), Aiyagari (1994)

• Codes: 

  • Huggett: this code does not solve the model's equilibrium but computes the value, policy functions, and implied stationary distribution. Students should work to replicate the original results. Visit Mark Huggett´s page for some important information.
