Multiproduct firms and dumping Shibayama, Chisato 1949 Ishii, Yasunori 7730 335 678.18 332 331 経済学 Multiproduct firms Closely related products Dumping Anti-dumping tariffs In this paper, we first develop a model of an international oligopolistic Cournot industry in which firms trade core goods and their incompatible accessories. We then examine some issues concerned with dumping. We find that such finns set the core goods price below cost (below-cost dumping, henceforth) even under perfect competition. We also find that firms might simultaneously engage in both price-discriminating dumping in the market for accessories and below-cost dumping in the market for core goods. Furthermore, we demonstrate that antidumping tariffs on both core goods and accessories may expand the dumping margin in the accessories market. journal article Waseda Society of Political Science and Economics 早稲田大学政治経済学会 2009-09-30 VoR application/pdf The Waseda journal of political science and economics 375 2 12 早稻田政治經濟學雜誌 AA1196115X 0287-7007 https://barrel.repo.nii.ac.jp/record/3304/files/The Waseda J. of Political Science and Economics375_2-12.pdf http://hdl.handle.net/10252/3826 https://barrel.repo.nii.ac.jp/records/3304 eng
