The ratio variable is a very important measure since in my theory it represents the organizational ecology of the region. I excluded regions with zero innovation. However, I am afraid of any function problem since I have Yi on the both side of the equation. I have read Bradshaw and Radbill (1987) paper discussing the use of ratio variables. It seems to me they were dealing with the ratio is generated by a third variable (Z), which is a bit different from my situation.
