I run a medium scale model for my thesis with a lot of shocks. I needed to group them to make the shock contribution more clear than the current way it’s showed by dynare. To do so, download attached dynare files and put them in /dynare/matlab/ folder. For instance, when using the Smets & Wouters model given by jpfeifer [Smets/Wouters (2007) in Dynare 4.2.5](https://forum.dynare.org/t/smets-wouters-2007-in-dynare-4-2-5/2491/1) , adding at the end of the mod file : ` options_.groups{1}={'ea';'epinf'}; options_.groups{2}={'eg';'eb';'ew'}; options_.groups{3}={'em';'eqs'}; options_.labels = char( 'Supply', 'Demand', 'Monetary' ); shock_decomposition y; ` this will aggregate the shocks by the given groups (those given in the example are dummy). if options\_.labels is not given, the code will automatically generate some group names. [http://img593.imageshack.us/img593/275/65060284.png](http://img593.imageshack.us/img593/275/65060284.png) I wanted to edit dynare argument of the function shock\_decomposition(), but i couldnt (dynare was giving me an error). I guess that some important dynare internal functions are declared in dynare.exe, my hex editor told me so (but i cannot edit it, i’m not a C coder).

First of all, you don’t need to deal with C-code. Everything here is done in Matlab. Second, the whole shock decomposition is stored in oo\_.shock\_decomposition. Thus, you could just use this information for graphing. ---

Hi all, I´m trying to do the same decomposition metioned previously, but I didn´t understand where should I place the part of the code below: options\_.groups{1}={‘ea’;‘epinf’}; options\_.groups{2}={‘eg’;‘eb’;‘ew’}; options\_.groups{3}={‘em’;‘eqs’}; options\_.labels = char( ‘Supply’, ‘Demand’, ‘Monetary’ ); Is it before or inside the estimation comand ? Or is it inside the shock\_decomposition comand ? I did a research about this in the forum, but I didn´t find the answer. Thanks for the attention. ---

Hi Frederico, I know this should be posted in the help part of the forum, but could you take a look and say what is wrong with the part of the code below? I got an “unexpected name” message from dynare, refering to the shock command inside the shock\_decompositon command. options\_.groups{1}={‘eps\_ah’;‘eps\_ys’;‘eps\_sh\_i’;‘eps\_sh\_w’;‘eps\_ys’;}; options\_.groups{2}={‘eps\_sh\_c’}; options\_.groups{3}={‘eps\_sh\_m’}; options\_.groups{4}={‘eps\_prsF’;‘eps\_yF’;‘eps\_iF’;‘eps\_piF’;‘eps\_prfF’;‘eps\_prfF’;‘eps\_proF’}; options\_.labels = char( ‘supply’, ‘demand’, ‘monetary’,‘external’); stoch\_simul(irf=0) y\_hat, picz\_hat, rer\_hat, l\_hat, ca\_y\_hat, i\_hat, c\_hat, inv\_hat; shock\_decomposition(parameter\_set = calibration, shocks= (options\_.groups{1};options\_.groups{2};options\_.groups{3}; options\_.groups{4}) ,labels= options\_.labels) y\_hat, picz\_hat, rer\_hat, l\_hat, ca\_y\_hat wr\_hat c\_hat inv\_hat pri\_hat; ---

try to move all the label afetr stoch\_simul and simply use the command shock\_decomposition without any other option and see if it works. Besides, I remember i had same troubles in running this options with dynare \> 4.3 version. I succesfully ues it with dynare 4.2.5 . If it does’t work i think you should post your mod file and see what i can do. ---

here is attached an example file with Smets & Wouters codes. [Smets\_Wouters\_2007\_Dynare425.zip](https://forum.dynare.org/uploads/default/original/2X/d/de9b868eac8141359d80db89d65a234072d79b56.zip) (22.8 KB) ---

Hi Vermandel and Frederico, I think this problem is related with the dynare version, because I ran the code above and got the chart without the labels. I´m using dynare 4.3.3. Which version are you using, Vermandel? ---

It works surely under dynare version 4.2.5 ---

Hi, I am working with dynare 4.3.3 version. I got, Starting Dynare (version 4.3.3). Starting preprocessing of the model file … ERROR: nonlinearomega.mod:1713.48-53: syntax error, unexpected NAME, expecting DATAFILE or LABELS or PARAMETER\_SET or SHOCKS What is unexpected since in nonlinearomega.mod:1713.48-53 I already have SHOCKS ( for confirmation, please, see the file above). Is this a bug? [nonlinearomega-2 2 USA 2.zip](https://forum.dynare.org/uploads/default/original/2X/e/e92fe8fd8e8641457d6904a182d091541f94ff8f.zip) (554 KB) ---

Sorry, but this is no supported function of Dynare. If the original author does not help you out, you will have to solve this yourself. ---

Thank you. I already solved it myself!
