DSGE.jl package implements the New York Fed dynamic stochastic general equilibrium (DSGE) model and provides general code to estimate many user-specified DSGE models. The package is introduced in the Liberty Street Economics blog post
The FRBNY DSGE Model Meets Julia.
(We previously referred to our model as the "FRBNY DSGE Model.")
This Julia-language implementation mirrors the MATLAB code included in the Liberty Street Economics blog post The FRBNY DSGE Model Forecast.
Documentation for the code can be accessed by clicking on the
docs button above (
stable for the most recent release,
dev for the most recent updates).
For documentation about the most recent model version, read this
We recommend new users take a look at our
as they read the documentation because the examples will make it easier to comprehend the documentation.
For details on the example scripts, see Running Existing Models.
The New York Fed DSGE team is currently extending the code to solve and estimate heterogeneous agent models. Filtering and smoothing algorithms are available in the registered package StateSpaceRoutines.jl.
An implementation of Sequential Monte Carlo (SMC) sampling, used for the estimation of DSGE models, can be found in the registered package SMC.jl. The foundational
AbstractModel type, from which the
AbstractDSGEModel type derives, is defined in the registered package ModelConstructors.jl.
Further extensions of the DSGE model code may be released at the discretion of the New York Fed.
DSGE.jl is a registered Julia package in the
General registry. To install it, open your Julia REPL, type
] to enter the package manager, and run
pkg> add DSGE
If you use any code that loads data (e.g. the example script
make_packet.jl), then you need make sure you have a FRED API key by following these instructions for the FredData.jl package.
If you are using Windows OS and you encounter the error
AssertionError: length(dirs) == 1, please see this issue. Additionally, please do not run the
plot.jl test if you are using Windows OS
because the generated output will violate the default filename length restriction on Windows. If you want to run this test, then
you need to enable long paths.
Note we do not test our code in Windows OS, so we cannot guarantee the code works properly in Windows.
DSGE.jl is currently compatible with Julia
v1.x (as of
DSGE.jl with Julia
v0.7, please check out tag
0.8.1. To do this, click on the drop-down menu that reads
branch:main on the left-hand side of the page. Select
v0.8.1. If you've already cloned the repo, you can simply run
git checkout v0.8.1.

v0.6, please check out tag
DSGE.jl package is not precompiled by default because when running code in parallel, we want to re-compile
the copy of
DSGE.jl on each processor to guarantee the right version of the code is being used. If users do not
anticipate using parallelism, then users ought to change the first line of
isdefined(Base, :__precompile__) && __precompile__(false)
isdefined(Base, :__precompile__) && __precompile__(true)
