To achieve this, he propagates the aid of more information on industry structure than simply concentration rates, of the fixing getting inter-globe differences in technical chance, and by determining the end result one to competition has on innovativeness using its effects to your post-invention return. The guy discovers that there surely is hardly any assistance into the theory you to definitely develops when you look at the aggressive rivalry drop off innovativeness.
