Seminar on input price discrimination
January 17, 12:45 - 14:00
BECCLE together with the Department of Economics are pleased to invite you to a seminar with Germain Gaudin (Copenhagen Business School) on Friday January 17. Gaudin will present his paper entitled “Input price discrimination, demand forms, and welfare’’ (joint work with Romain Lestage). The paper studies industries in which retailers face asymmetric input prices from their upstream suppliers, such as the Norwegian grocery market.
Please note that the venue is the Department of Economics, University of Bergen (Fosswinckelsgate 14), Seminar room 327 (3rd floor).
Abstract: “In this paper, we analyse the effects of input price discrimination by an upstream monopolist selling to firms with various degrees of efficiency. When downstream markets are independent, we first study whether the upstream monopolist has an incentive to reduce or to increase the relative cost difference amongst downstream firms. Then, we examine the impact of input price discrimination on output and welfare. A key determinant of the effects of input price discrimination on prices, output, and welfare is the sum of demand curvature and pass-through elasticity. We apply our findings to the set of demand forms with constant pass-through rates, as well as other demand forms. We also discuss the cases of demand asymmetries across markets and price competition downstream”.
