for endogenous regressor in a recursive biprobit Date   Mon, 18
Mar 2013 14:23:58 -0400   I am estimating a recursive biprobit
model with endogenous regressor, Y2, as such:  Y1 = X1 + X2 + Y2
Y2 = X1 + X3 + X4  I want to calculate the marginal effect of Y2
on Y1.  I know how to calculate the marginal effects of a
variable that appears as a regressor in a single equation (e.g.,
X3 or X2 in my example) or in both equations (e.g., X1 in my
example) of a recursive biprobit.  But I am wondering if there
is a special formula required to calculate the marginal effect
of the endogenous regressor (Y2) on the outcome of concern (Y1),
since the endogenous regressor appears as an outcome in one
equation and a regressor in the other (given that the model is
recursive)?  Does one have to account for the intercept of the
Y2 equation in a particular manner, or something of the sort,
when making this
