When vertical trading is conducted via linear tariffs, PPFI is pro-competitive and welfare-increasing. While under two-part tariffs, it is anti-competitive and welfare-decreasing. These hold irrespectively of the degree of product differentiation, the observability or secrecy of contract terms, the mode of downstream competition, and the distribution of bargaining power between firms.engAtribución-NoComercial-SinDerivadas 3.0 EspañaPartial Passive Forward IntegrationTwo-Part TariffsLinear TariffsCompetitionWelfareworking paperD43L13EconomíaDT/0000001926
