Error using save
Unable to create ‘ee\_results.mat’ because ‘ee\Output’ does not exist.
Error in ee.driver (line 1024)
save([M\_.dname filesep ‘Output’ filesep ‘ee\_results.mat’], ‘oo\_’, ‘M\_’, ‘options\_’);
Error in dynare (line 281)

dynare ee.mod;
It seems a new problem. How should I fix it?

I placed the same m and mod files in two folders with different names using the same version of Dynare. The simulations ran successfully in both cases, but while one folder generated the Output correctly, the other failed to do so.

Most of the time, there is an issue with write permission, typically due to working on a cloud-synched folder like one on Dropbox.

Thanks a lot! I think your suggestion is probably correct. I often run MATLAB as admin. But it’s odd that only ee.mod in the folder fails to run, while others like exit.mod work.

If it’s really about Dropbox, then the problems appear stochastically.

No, I didn’t use Dropbox with MATLAB. All files are stored locally. In the end, I resolved the issue by reinstalling MATLAB and Dynare.
