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 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 discuss and evaluate the incentives for vertical expansion and vertical mergers in the payments systems industry paying particular attention to the implications of the existence of network effects in this industry. We assess the incentives of large merchants to extend vertically into payments...

“Vertical market power” is a contradiction in terms because “market power” is essentially horizontal—that is, it depends on relationships of firms within markets. FERC invokes the term to assess “convergence” mergers between electricity generators and natural gas suppliers. It...

We analyze collusion in two comparable market structures. In the first market structure only one firm is vertically integrated; there is one more independent firm in the upstream industry and another independent firm in the downstream industry. In the second market structure, there are only two...

This paper looks at the potential effect of partial ownership on the generation and the transmission sector of electricity markets. Ideally, in liberalized electricity markets, transmission is separated form generation. The transmission sector is a natural monopoly operated by a regulated...

This paper contains an analysis of stylised natural gas and electricity supply sectors. Power plants operate either on natural gas or on a competing fuel – e.g. oil. The competing fuel is assumed to be traded at world market price whereas natural gas is sold by a national monopoly. The paper...

The Spanish electricity spot market is highly concentrated both on the seller and the buyer side. Furthermore, unlike electricity spot markets in other deregulated electricity systems, large buyers and sellers are typically vertically integrated. This allows both large net sellers and large net...

This paper analyzes the impact vertical integration has on upstream collusion when the price of the input is linear. As a first step, the paper derives the collusive equilibrium that requires the lowest discount factor in the infinitely repeated game when one firm is vertically integrated. It...

We provide a simple model to investigate decisions on vertical integration/separation. The key feature of this model is that more than one input is required for the final products of the local downstream monopolists. Depending on their cost structure, downstream firms' decisions on vertical...
