Re: Benchmark checked with iterlim=0 but GAMS does not find solution with iterlim>0

Hi, thanks a lot for your hints. I finally understand where the problems emerge! And yes, I scaled the SAM already right from the beginning (by a factor of 1000). When I increase scaling by another order of magnitude, the solver returns an optimal solution (but it takes ~2 minutes). I'm now thinking...

Re: Benchmark checked with iterlim=0 but GAMS does not find solution with iterlim>0

Thanks again for your suggestions. I'm 100% sure that the SAM is balanced and GAMS reads in everything correctly from Excel. The infeasibility output looks as follows: ** EXIT - iteration limit. o Major Iterations. . . . 0 Minor Iterations. . . . 0 Restarts. . . . . . . . 0 Crash Iterations. . . . 0...

Re: Benchmark checked with iterlim=0 but GAMS does not find solution with iterlim>0

Good morning Renger (here it is 8 a.m.), first of all, thanks for your reply! Regarding your comment, where can I find out the size of the infeasibility? Unfortunately I can't attach the model due to institutional rules, but I can show you what I changed. With one representative agent, the demand bl...

Benchmark checked with iterlim=0 but GAMS does not find solution with iterlim>0

Dear community, I've now quite some experience in MPSGE modelling but currently encounter a problem that I've never had before. First, I correctly calibrated a model to a small open economy SAM with one representative agent. Afterwards, I disaggregated the SAM data of the private household side (exp...
