WHAT DO WE KNOW FROM EPRG MODEL?

The aim of this paper is to present the fundamental ideas behind EPRG model. They are discussed with some illustrating examples. Moreover, some attention is drawn on the evolution from one orientation to another. In particular, the geocentric orientation is widely discussed. General Electric is studied in more details as a particular case of the geocentric orientation. Finally, some non-market dissertations are presented, on how geocentrism can evolve and some threats to the public interest are sketched.
