Dear All,
I am working with an instrumental variables model where the dependent
variable of the outcome (second stage) equation is dichotomous. I have
been using the ivprobit command but my data likely have serially
correlated errors. To that end I like the options and flexibility of
ivreg2 (with the bw option to deal with serial correlation) and wonder
about the optimality of using that command as a linear probability
model. I understand that I will have predictions that may range outside
of the (0,1) interval but I am more concerned about the efficiency and
bias of my estimates. Any thoughts or ideas would be most appreciated.
Thanks,
