Our analysis starts from the observation that with progressive consolidation in retailing and the spread of private labels, retailers increasingly take over functions in the vertical chain. Focusing on innovation, we isolate various reasons for why when a large retailer grows in size, this can...

We consider a possible game-theoretic foundation of Forchheimer's model of dominant-firm price leadership based on quantity-setting games with one large firm and many small firms. If the large firm is the exogenously given first mover, we obtain Forchheimer's model. We also investigate whether...

The Icelandic Competition Council recently ruled that a cement supplier with 75% market share is not dominant. The ruling was based on countervailing power of local concrete producers. To test the economic arguments for the ruling, we present a simplified bilateral oligopoly model of the...

We discuss competition effects and possible regulation of vertical integration in internet-based two-sided markets against the background of the ongoing antitrust allegations against Google. In such markets, network effects and economics of scale often lead to dominating companies which are...

Lignite mine and power plant can operate as two separate entities, two entities in one holding or joint venture and as the one vertically integrated energy producer. Each of these solutions has the influence on operation of this tandem including realization of its individual and joint...

The newest outcome of bilateral monopoly (BM) of lignite opencast mine & power plant analysis have been discussed. The determinism of optimal solution maximising joint profits not only in quantity of lignite - the size and shape of the ultimate pit (characteristic to classical solution) but also...

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...

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 application of Nash bargaining solution to profit division in negotiation between opencast lignite mine and power plant has been discussed. Different proposals of status quo point usage and ways of its determination for profit sharing both in strategic and tactical/operational negotiation...
