Bertrand Competition with an Asymmetric No‐discrimination Constraint
研究禁止具有市场势力的企业实行价格歧视的不对称约束，发现当垄断市场较小时，该约束会阻碍进入并降低福利。
Regulators and competition authorities often prevent firms with significant market power, or dominant firms, from practicing price discrimination. The goal of such an asymmetric no‐discrimination constraint is to encourage entry and serve consumers' interests. This constraint prohibits the firm with significant market power from practicing both behaviour‐based price discrimination within the competitive segment and third‐degree price discrimination across the monopolistic and competitive segments. We find that this constraint hinders entry and reduces welfare when the monopolistic segment is small.
