假设我要估计一个discrete/continuous choice model.
第一阶段是discrete choice.
consumers face five alternatives.
I use a multinomial logit model to estimate consumers five vacation choices.
第二阶段是continuous choice. After consumers pick one choice, I would like
to know how much they spend on each choice.
我可以直接用OLS 估计吗? 假定第一个choice是去欧洲, 然后直接用OLS估计choice 1
的subsample. The dependent variable is the money spent on vacation in Europe.
我也用了Heckman selection model 估计, first stage 是 是否选择去欧洲(probit),
second stage 是 how m
