Contains the functions and classes for solving, filtering and estimating DSGE models at the ZLB (or with other occasionally binding constraints).

A collection of models that can (and were) used with this package can be found in another repo.

Installing the repo version is as simple as

pip install pydsge

There is some preliminary documentation out there.

pydsge is developed by Gregor Boehl to simulate, filter, and estimate DSGE models with the zero lower bound on nominal interest rates in various applications (see my website for research papers using the package). Please cite it with

We appreciate citations for pydsge because it helps us to find out how people have been using the package and it motivates further work.

The parser originally was a fork of Ed Herbst's fork from Pablo Winant's (excellent) package dolo.
