We analyze the relation between European natural gas storage facilities and price patterns at major trading points, considering the theory of storage to derive a testable hypothesis imposed by the non-arbitrage condition. To model the efficiency of the natural gas market, we apply two indirect...

In 2004, European competition law had been faced with considerable changes due to the introduction of the new Council Regulation No. 1/2003. One of the major renewals was the replacement of the centralized notification system for inter-company cooperations in favor of a so-called legal exemption...

How should we select winning bids of generation units for strategic reserves that consist of capacity bids and energy bids? In this paper, we analyze two selecting mechanisms (scoring rules): "simultaneous" and "sequential". In case of a simultaneous scoring rule, capacity and energy bids are...

This paper shows with a formal model that under monopoly regulation, OPEX-risk can be a source for a CAPEX-bias. If OPEX and CAPEX are substitutes, the regulated firm can reduce the risk of the firm and thereby reduce the true cost of capital by rebalancing OPEX and CAPEX. If the allowed...

Der Einsatz von Informations- und Kommunikationstechnologien (IKT) ist sowohl mit positiven als auch negativen Effekten verbunden. Der negative Nachhaltigkeitsbeitrag besteht z. B. im Ressourcenverbrauch für die Herstellung der einzelnen Komponenten (z. B. Antennen für die Basisstationen des...

In dieser Studie nehmen wir neben den klassischen Zielen der Frequenzregulierung, wie z. B. der Schaffung wettbewerblicher Marktstrukturen, auch die Aspekte der Nachhaltigkeit und Resilienz in den Blick. So hat z. B. die Ausgestaltung von Versorgungsauflagen für Mobilfunknetzbetreiber im...

The European Commission has intensively discussed the mandatory separation of natural gas transmission from production and services. However, economic theory is ambiguous on the price effects of vertical separation. In this paper, we empirically analyse the effect of ownership unbundling of...
