Abstract

We provide the analytical explanation of strong interactions between precautionary sav- ing and liquidity constraints that are regularly observed in numerical solutions to consump- tion/saving models. The effects of constraints and of uncertainty spring from the same cause: concavification of the consumption function, which can be induced either by constraints or by uncertainty. Concavification propagates back to consumption functions in prior periods. But, surprisingly, once a linear consumption function has been concavified by the presence of either risks or constraints, the introduction of additional concavifiers in a given period can reduce the precautionary motive in earlier periods at some levels of wealth.

How to Execute this Notebook (with conda)

Install miniconda on your computer

  1. Open a Terminal (MacOS) or the Anaconda Prompt (Windows)
  2. At a command line, change the working directory to the one where you want to install
    • On MacOS/unix, if you install in the /tmp directory, the repo will disappear at reboot:
    • cd /tmp
  3. git clone https://github.com/econ-ark/LiqConstr --recursive
  4. cd LiqConstr
  5. conda env create -f ./binder/environment.yml --prefix ./condaenv
    • This creates ./condaenv inside your clone of the repo, containing dependencies.
  6. conda run --prefix ./condaenv pip install jupyterlab
  7. conda run --prefix ./condaenv jupyter-lab
