| Subject | st: joint effect of two endogenous variables in ivprobit |
| Date | Mon, 2 Aug 2010 06:41:59 -0700 (PDT) |
Dear all, I have a probit model with two endogenous variables (y1 and y2), and I want to estimate this model with IVprobit method, but my instruments don't have enough independent variation in y1 and y2 and thus the effects of y1 and y2 on the dependent variable can't be isolated, so I want to compute and test the significance of the joint marginal effect of y1 and y2, i.e. the effect on dependent variable when both of y1 and y2 increase by 1 unit. Does anybody know how to realize this idea?
