Dear Gretl users,
i'm doing panel regression where i suppose there's a reverse causality
among independent and dependent variables and I can't find instrument
for them .
Does exist a test that tell me if such reverse causality exists?

Dear Andrea,
assume that two barmen work in a bar, in different nights, and they both
prepare the same cocktail made of gin and lemonade. But one fills more
or less half of the glass with gin, fills it with lemonade until it is
exactly full, and then stirs. The other fills more or less half of the
glass with lemonade, fills it with gin until it is exactly full, and
then stirs.
The cocktails produced by the two barmen have, on average, exactly the
same amount of alcool, lemon and any other chemical component.
By only analyzing the cocktails produced during a given night, you can
presumably identify a negative relationship between the amount of alcool
and the amount of lemon. But intuitively, do you think that Gretl, or
any statistical software, could ever tell you which barman is working
tonight (that is, in which sense the causality is going)?

So i think the problem is to find good instrument.
Thank you

Dear Andrea,

If I understand your description of the problem correctly, especially
the non-existence of suitable instruments, then you indeed have a
problem, because a standard test of endogeneity of the regressors would
be based on such instruments.
However, if you're already pretty sure that the instruments are invalid,
aren't you equally sure that indeed there is "reverse causality"? If so,
why do you still need to test? (Half-serious question.)
