Collusive effects of a monopolist's use of an intermediary to deliver to retailers

Teichmann, Isabel; Schlippenbach, Vanessa von - 2014

A manufacturer contracting secretly with several downstream competitors faces an opportunism problem, preventing it from exerting its market power. In an infinitely repeated game, the opportunism problem can be relaxed. We show that the upstream firm's market power can be restored even further...

Multi-product bargaining, bundling, and buyer power

Dertwinkel-Kalt, Markus; Wey, Christian - 2019

We re-consider the bilateral bargaining problem of a multi-product, manufacturer-retailer trading relationship. O'Brien and Shaffer (Rand JE 35:573-598, 2005) have shown that the unbundling of contracts leads to downward distorted production levels if seller power is strong, while otherwise the...

Resale price maintenance in a successive monopoly model
