Liberalization of network industries frequently separates the network from the other parts of the industry. This is important in particular for the electricity industry where private firms invest into generation facilities, while network investments usually are controlled by regulators. We...

I develop a framework to study common situations, in which substitute goods are sold in separate, good-specific multi-unit (pay-as-bid) auctions. I characterize bidding behavior and investigate auction design features that could increase revenues. The setting I develop gives rise to an...

This study empirically examines a sample of national wireless spectrum assignments for the period 2000-2007 to identify the sources of revenue variations. An econometric model that recognises the censored nature of the sample relates per capita winning bid (per Mhz) values to auction design...

A shift from zonal pricing to smaller zones and nodal pricing improves efficiency and security of system operation. Resulting price changes do however also shift profits and surplus between and across generation and load. As individual actorscan lose, they might oppose any reform. We explore how...

This paper proposes a tractable competing mechanism game where each seller simultaneously posts a trading contract that specifies a menu of dominant strategy incentive compatible (DIC) direct mechanisms conditional on an array of messages sent by buyers, and each seller subsequently chooses a...

Adequately designed prices are essential to achieve efficient coordination between the electricity network and market participants. However, consumer prices comprise several, possibly distorting price components. In an analytical model, we examine different regulatory settings, consisting of...

Due to technological convergence, multiple infrastructures can now offer broadband or triple-play services, while the existing access regulation is based on a single essential network. We show that continued asymmetric access regulation of one network does not control sufficiently for market...

This paper quetions whether or not mandatory unbundling delayed DSL deployment by BellSouth. By exploiting a law change in Kentucky and variation in access prices across markets, I find that deregulation in Kentucky triggered deployment, but no evidence that access prices affected deployment...

We analyze the incentives of a vertically integrated firm, which is a regulated monopolist in the wholesale market and competes with an entrant in the retail market, to invest and to give access to a new wholesale technology. The new technology represents a non-drastic innovation that produces...

In this paper, we study the adjustments made by National Regulatory Authorities to simple margin squeeze tests, in order to model a reasonably efficient operator. More precisely, by inspecting the possible differences between an entrant and an incumbent that would cause a market disadvantage for...
