This paper revisits, in an environmental context, the vertical restraints literature as developed by Bonanno and Vickers (1988), Gal-Or (1991), Lin (1988) or Nakache and Soubeyran (1998) in an oligopolistic and deterministic situation. This literature considers constant returns to scale at the...

Sports organizations, Hollywood studios and TV channels grant satellite and cable networks exclusive rights to televise their matches, movies and media contents. Exclusive distribution prevents viewers from watching attractive programs, and reduces the TV-distributors incentives to compete in...

For the hypothetical deposit with parameters similar to KWB “Konin” S.A. conditions; lignite prices and proposed divisions are calculated and results were discussed under the angle of the fairness (equity) of the division and the possibility of their approval by both sides. A sensitivity...

In some markets vertically integrated firms sell directly to final customers but also to independent downstream firms with whom they then compete on the downstream market. It is often argued that resellers intensify competition and benefit consumers, in particular when wholesale prices are...

Different structures of lignite mines and power stations, which have appeared on the Polish market as a result of its transformation and the privatisation, were discussed. The attention is focused on the fact that the practice is overtaking the theory because there is lack of models of...

For methods of the profit division in the bilateral monopoly of the mine and the power station sug-gested in the first part of this paper the formulae for lignite price and shares in the joint profit of the mine and the power station are calculated. The proposed profit division contain: the...

The transformation of world?s main stock markets into enterprises acting in a competitive environment is in progress and its consequences are not all known. Three strategies are competing with each other: vertical integration of exchange and CSD; horizontal growth of the market share to an...

We demonstrate the sensitivity of the location of downstream firms, engaged in sequential spatial competition, to the vertical structure of an industry where no downstream firm can produce all varieties demanded.

In contrast with previous studies we assume no ex-ante commitment over the �price or quantity� type of contract which downstream firms will independently offer consumers in a two-tier oligopoly. Under competing vertical chains, we propose...

En este artículo se estudian los equilibrios de mercado resultantes en una industria de facilidades esenciales, con un monopolio upstream y competencia oligopólica downstream, la que enfrenta posteriormente entrada en el segmento monopólico. Se encuentra que la competencia de duopolios...
