Cocco, Gomes, & Maenhout (2005), "Consumption and Portfolio Choice Over the Life Cycle"

A replication by Mateo Velásquez-Giraldo and Matthew Zahn.

Quick launch: the following link launches a Jupyter notebook with the main results.

Description

This repository corresponds to the Final assignment of the course Advanced Macroeconomics I at Johns Hopkins University, by Professor Christopher D. Carroll.

Location of main files:

1. A notebook attempting to replicate the paper's main results using HARK can be found at Code/Python/CGMPortfolio.ipynb.

2. A document going into more detail on our attempt to replicate can be found at CGMPortfolio.pdf.

3. The code that generates all the figures and results in the previous document can be found at Code/Python. Files can be run independently, or all at once through the script ./do_ALL.py. Additional files ./do_MIN.py and ./do_MID.py are made available to execute subsets of the results.

• ./do_MIN.py: solves the baseline model plotting its policy functions, and presents mean simulated life-cycle behavior of variables of interest. Runtime: ~400 seconds.
• ./do_MID.py: additionally compares the policy functions obtained with HARK with those that we obtain from executing the authors' FORTRAN 90 code. Runtime: ~600 seconds.
• ./do_ALL.py: additionally computes all the results from the apendices, in which we alter the baseline model in HARK to cases in which analytical solutions are available. Runtime: ~1300 seconds.

Note: runtimes are estimated using an Intel Core i7-6700HQ CPU @ 2.60GHz.

4. The original Fortran 90 code made available by the authors can be found in Code/Fortran.

Package requirements
