Dynare.jl ([GitHub - DynareJulia/Dynare.jl: A Julia rewrite of Dynare: solving, simulating and estimating DSGE models.](https://github.com/DynareJulia/Dynare.jl)), a Julia rewriting of Dynare,  
is now ready for testing by users. Dynare is a software for solving,  
simulating and estimating Dynamic Stochastic General Equilibrium  
(DSGE) models widely used in macroeconomics.

The following features are implemented: steady state, local  
approximation of the solution at 1st and 2nd order,  
perfect foresight simulations, forecasting, optimal policy.

Documentation is available at [https://DynareJulia.github.io/Dynare.jl](https://DynareJulia.github.io/Dynare.jl)

Thank you for reporting any error, question or desired additional feature.

Nice package ! Considering the post about the “1.5 language” and the original Matlab version of dynare, I was wondering about your opinion on this Matlab to Julia reimplementation 🙂

Thanks very much for this project, I am looking forward to using it.

With the current version (0.9.11), I can run the simple RBC estimation example from [Estimation problem in Julia - Dynare Julia - Dynare Forum](https://forum.dynare.org/t/estimation-problem-in-julia/25412) without errors, but I can’t find the estimation results anywhere. I looked inside the context structure, as well as in the subdirectories that are created. Is this expected with 0.9.11?

Dear Michael,

thank you for reporting the problem. There is obviously something broken in v0.9.11 with estimation. I will release a correction soon.

Note the error message at the end of the run:

```julia
ArgumentError("matrix contains Infs or NaNs")

```

Best

Michel

OK, thanks. I will try to test various things in the future.

Dear @mcreel ,

I just released Dynare v0.9.12 that should solve the problems with the estimation code.  
Just update your environment:

```julia
] update

```

You may have to restart Julia.  
I modify the `. mod` file so that you see the first order approximation results  
See [DynareJulia estimation example used in https://forum.dynare.org/t/estimation-problem-in-julia/25412 and https://discourse.julialang.org/t/ann-dynare-jl-is-now-ready-for-testing/108177/4 · GitHub](https://gist.github.com/MichelJuillard/ff1cf3601e2f7c34d743f7e47aa79e03)

Hi Michel,  
Thanks, it seems to be working well now! Inside context.results, I find

```julia
estimation: Dynare.EstimationResults([0.9208808863932328, 0.04441817638943685], [2.454376213054909, -3.114106515175857], [0.03408840700653537, 0.011260134441262335], [0.4220899442337999, 0.22912707304878288], [0.0011620194922432098 -0.00036399187020596423; -0.00036399187020596423 0.00012679062763530226], [0.17815992102329234 -0.09061689673115145; -0.09061689673115145 0.052499215603902284], 0)

```

which seems to be the estimation output. I don’t know quite how to interpret it, but the estimation seems to work. Am I supposed to see a nice table of estimated coefficients, standard devs., etc., as in Dynare on Octave? That is not appearing.

Next week, I will try MCMC, etc…

Thanks!

That is very strange. I get the following output. The estimation results are at the end of the log:

I simply forgot the semicolon at the end of

```julia
context = @dynare "RBCmj1";

```

With that, everything is fine. Many thanks!

Edit: running it on my own model, I can say that it is impressively fast compared to Dynare on Octave.

Do you prefer questions about Dynare.jl here, or on the Dynare forum? I do have a few questions.

Regarding testing, I have done MCMC, order=1, with a model of my own, no problems.

Both are OK for me, but for the users it would be better to have them in a single place. Let’s have the questions on the Dynare forum ([https://forum.dynare.org](https://forum.dynare.org)).  
If the question or the suggestion is more about the Julia implementation then maybe they are better here, but each question should have its own thread. Looking forward to your input.

Hi Michele, when you get a chance, I have had problems using perfect foresight with dynare julia. The .mod file runs ok in Matlab for perfect foresight, and the context runs ok in the julia version, but I get errors with the set of commands in Julia, this is the comannd I use in Julia: Dynare.perfect\_foresight!(  
context = context,  
periods = 1000,  
datafile = “shocks\_RBC6.csv”,  
display = true,  
maxit = 50, mcp = true,  
tolf = 1e-5, tolx = 1e-5)

error message; ArgumentError: Invalid buffers for SparseMatrixCSC construction n=72, colptr=75-element Vector{Int64}, rowval=90-element Vector{Int64}, nzval=90-element Vector{Float64}

I am using Julia 1.12 and the latest version of Dynare.jl I have had no problems with the stoch\_simul but I want to try the perfectforesight solver as well. Thanks much.

Actually elimating the varexo\_det for varexo, and putting in zeros for the shocks at the start and end for the steady states of the shocks get the perfect foresight to solve but it is not reading in the shocks, all I get is steady state values for the simulated variables. Any reason why the shocks are not being read in, only zeros?

Dear Paul

Thank you for your message. Can you provide an example please?
