Dear Prof. Jpfeifer, I have a similar model and questions with petiteelf. I posted a forum topic > [@Loop over parameters to find maximized welfare](https://forum.dynare.org/t/loop-over-parameters-to-find-maximized-welfare/12358/3): > > Thank you for your quick reply!!! It’s real helpful!! But I still have some questions: done I am not sure whether my shock size is correct… I just follow the .mod file from Matteo Iacoviello, 2015. " [Financial Business Cycles](https://ideas.repec.org/a/red/issued/14-27.html) ," [Review of Economic Dynamics](https://ideas.repec.org/s/red/issued.html), Elsevier for the Society for Economic Dynamics, vol. 18(1), pages 140-164, January. And my model structure is basically modified from it. But I don’t know what’s the effect of different scale of shock size. Should I choose my shock … to ask for help. And there are still some problems left to be helped. Since petiteelf didn’t put his .mod and .m file here, I don’t know his model structure at all. But from his questions listed above, I couldn’t find out the exact difference between his questions and mine. // What confuses me is that you suggest me not to run **get\_consumption\_equivalent\_conditional\_welfare.m** in my forum topic, but here you suggest petiteelf to do that. Why do you give a totally different suggestion? I am so confused. 😭 Please help me solve these problems. Many thanks. --- _[View the full topic](https://forum.dynare.org/t/optimal-policy-problems/12347)._
