1	Quality provision in duopoly Argenton, Cédric January 2006 (has links) This dissertation comprises three essays revisiting the classical topic of quality provision in a duopoly. Two essays consider a situation in which consumers cannot identify the origin of an individual product but observe or infer the average quality of the units brought to the market: Chapter 2 studies the case where the two producers bargain over a minimum quality standard before deciding about their own quality level, while Chapter 3 deals with the case where qualities are (exogenously) fixed and producers have to decide about the quantity they will offer for sale. The final essay (Chapter 4) switches to a perfect-information environment and asks whether the producer of an inferior variety is able to deter the entry of a superior product by having retailers sign onto exclusivity contracts. / Diss.
