Note that elasticity is not the same as marginal effect.
The marginal effect is how much your y of choice
(observed or latent) changes for a unit increase in x,
and the elasticity is the percentage change in your y of
choice for a percentage change in x. Both can be computed
with -mfx- (dydx is marginal effect and eyex is
elasticity) I have to leave for a meeting now, but later
I will add an example.
Hope this helps,
