Summary

This repository presents a two-asset consumption-savings model and serves as the documentation of an open-source implementation of methods to solve and simulate it in the HARK toolkit. The model represents an agent who can save using two different assets---one risky and the other risk-free---to insure against fluctuations in his income, but faces frictions to transferring funds between assets. The flexibility of its implementation and its inclusion in the HARK toolkit will allow users to adapt the model to realistic life-cycle calibrations, and also to embed it in heterogeneous-agents macroeconomic models.

Replicating the results

To reproduce all the results in ./RiskyContrib.pdf you can

Use nbreproduce (requires Docker to be installed on the machine).

# Clone this repository
$ git clone https://github.com/Mv77/RiskyContrib

# Change working directory to RiskyContrib
$ cd RiskyContrib

# Install nbreproduce
$ pip install nbreproduce

# Reproduce all results using nbreproduce
$ nbreproduce

Install a local conda environment and execute a script that generates all the results.

$ conda env create -f environment.yml
$ conda activate RiskyContrib
# execute the script to create figures
$ ipython do_ALL.py
