I this paper we consider a market situation in which initially there is an unintegrated monopoly upstream entry and vertical integration. The equilibrium entry mode -sharing the incumbent facility or building a new facility- is derived as well as the equilibrium market structure. Several policy...

In this paper we consider a market situation in which initially there is an unintegrated monopoly upstream that owns an essential facility and two downstream firms. Then the market is liberalized allowing upstream entry and vertical integration. The equilibrium entry mode--sharing the incumbent...

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...

We study competing vertical chains where upstream and downstream firms bargain over their form and terms of trading. Both (conditionally) inefficient wholesale price contracts and efficient contracts that take the form of price-quantity bundles (and not of two-tariffs) arise in equilibrium under...

I present the following proposal: information revealed during non-cartel investigations by competition law enforcement authorities, such as evaluation of M&As or investigation of monopolization (dominance) conduct, should be directly used to investigate and prosecute cartels. Currently, in...

We examine the competitive effects of the vertical integration of gasoline refineries and retailers in the U.S. Adapting the first-order condition approach of static oligopoly games to the analysis of vertically related oligopolies, we develop a novel framework for directly evaluating the...

Due to potential abuse of the market power at wholesale and retail market level for natural gas the Federal Cartel Office in Germany prohibited further forward integration of gas importing firms with retail incumbents from 2005/2006 to 2010. The Authority argued that the very few dominant gas...
