Dear Prof. Jpfeifer,
I have a similar model and questions with petiteelf.
I posted a forum topic
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.
