In this paper I both review expert contributions from different jurisdictions pertaining to norms on abuse of dominance and norms on abuse of non-dominance, and assess to what extent these two families of dispositions are theoretically and practically reconcilable.

As a matter of comparative law, the first question that arises is the risk of regulatory drift in the application of norms on abuse of dominant position. That happens, for instance, with commitment decisions (which I prefer to term ‘para-regulatory’ decisions), and with the particularly aggressive attitude toward the enforcement of exploitative ‘unfair’ prices (Article 102 lit. a) TFEU), by some national competition agencies. The latter may require them to (unduly) set, and thus regulate, ‘fair’ prices. To avoid that, a proposal is made to reinterpret the norm as prohibiting only supra-monopolistic prices (as effectively exclusionary, rather than exploitative). My conclusion on this is that such a reinterpretation would unreasonably eliminate any difference between a monopolistic price that is ‘exceptionally justified’ because it is welfare-enhancing and one that is not.

On the side of norms on abuse of non-dominance, although differently constructed (as situations of economic dependence or of superior bargaining power), the core difference among jurisdictions resides on whether the abuse also amounts (as in Japan and North Korea) to an infringement of competition laws (ie has an effect on the relevant market), or not. In the latter case, unilateral conducts by non-dominant firms may still be scrutinized if the relevant market is defined in a very narrow fashion (and consequently dominance is ascertained). The two hypothesis taken together, however, risk transforming the competition agency into a regulator for policing detailed contractual terms and fairness.

One might thus question whether intervening to protect weaker economic partners makes sense at all from a general welfare standpoint; or, on the contrary, it is legitimate to enforce the weaker party’s ‘right’ or freedom to compete in the market.

On a normative ground, in order to reconcile norms on abuse of dominance and of non-dominance, I suggest for those jurisdictions that keep abuse of non-dominance within the realm of competition laws (by requiring an effect on the relevant market to be ascertained), either to remove this latter requirement or to expressly establish flexible thresholds of non-dominance.
