The academic literature on loyalty discounts and exclusive dealing demonstrates that the welfare effects of these practices are ambiguous and that market details determine the direction of the effect.

Moreover, he claims, “anticompetitive effects are exacerbated if multiple sellers use loyalty discounts.”
