That doesn't seem right, the log of 0 is missing, and
if you artificially want to replace that with some
number it should be very very negative and not 0.

yes, dydx will now get you elasticities in that case
btw terminology like log linear is not standardized
across disciplines, for instance I was taught to call a
model with both the y and the x logged a log-log model
instead of a log linear model. So instead of using such
terminology I would just say that both the y and the x
is logged.
Hope this helps,
Maarten
