Although it is not wholly recognized by scholars, the ordoliberal thought has had a direct influence on the EU law and, in particular, on the EU competition law. Today, this approach seems old-fashioned respect to the US variety of liberalism supporting by Chicago School. We will deal with two ordoliberal concerns: (i) the idea of as-if competition and (ii) the process of polarization of economic power. The aim of this work is not to defend ordoliberal approach, but to try to offer a more modern treatment in order to better evaluate its pros and cons.
