This paper derives sufficient conditions for global identification innonlinear models characterized by a finite number of unconditional momentrestrictions. The main contribution of this paper is to provide a set ofassumptions that are alternative to those of Gale-Nikaidô-Fisher-Rothenberg,and which when satisfied guarantee that the moment conditions globallyidentify the parameters of interest.
