Without looking much into what your code does -- did you run -ml
check-? May be your model is not identified, or something, so that
your likelihood cannot be evaluated at all. -ml trace- might help with
problems, too.

Looks like your -forvalues j- cycles replace the `cv' variable with
the last offer_hat`j' variable rather than the average of any kind.
Check your code if that's what you want to do.

You might also be able to use -gllamm- for your purposes.

First alternative (sv) is a utility of "offer" and a second one (cv) is a simple average of "offer_hat`j'". There are 680, 364, 165, 56, 10 and 2 variables "offer_hat`j'" in 1st, 2nd and so on periods respectively. Prior to estimation I have generated variable "i" that contains 680, 364, 165, 56, 10 and 2 for the respective time periods.
