Under collusion, firms deviate from current profit maximization in anticipation of future rewards. As current profit maximization places little restrictions on firms' pricing behaviour, collusive conduct is hard to infer. We show that bids from certain firms in the Colombian wholesale...

In order to realise the energy transition towards a more sustainable, inclusive and just energy market, the traditional model of the electricity market, with big corporations producing electricity and passive consumers at the receiving end, is changing. These changes also require the adaptation...

The original full study analyses the ongoing reform of the European electricity market. Specific design instruments proposed by the European Commission and supported by the European Parliament amendments are assessed in detail. A novel approach to modelling financial flows in electricity markets...

The proposed reform of the electricity market design maintains crucial elements of the existing system to ensure continued efficient operation. The impact that changing the rules on longer-term contracts will have on consumer prices and investment will depend on the concrete language of proposed...

Utilities increasingly sell electricity using complex menus of time-constant and time-varying price schedules. We study how to design such a menu to maximize social welfare in a second best environment where the marginal private and external costs of generating electricity vary over time,...

Die Politik scheint entschlossen, in die Gestaltung des Stromgroßhandelsmarktes einzugreifen, um Krisengewinne und -belastungen umzuverteilen. Einige Vorschläge in diese Richtung würden die Probleme jedoch verschärfen. Es werden Handlungsoptionen für ein neues Strommarktdesign aufgezeigt...

This research project quantifies the impact of renewable energy policy co-ordination in the Single Electricity Market of Ireland. Renewable energy targets are determined independently by both jurisdictions on the island. To date, renewable electricity targets have been similar in each...

Confronted with sustained high electricity prices, some Member States demand a deep reform of electricity markets in the EU. Conversely, other Member States ask to strictly respect the current market framework. In this comment, we review what these governments have publicly stated, and we...

Die Energiekrise zwingt Deutschland und die EU-Staaten energiepolitische Entscheidungen neu zu bewerten und gegebenenfalls anzupassen. Zunächst rückt die Notwendigkeit, die erneuerbaren Energien schnell und ambitioniert auszubauen noch stärker in den Fokus. Zudem gibt es einerseits...

Die Politik in Deutschland und vielen anderen EU-Ländern hat seit Spätsommer 2022 zunehmend die Option einer Gaspreisbremse und von Transferzahlungen an private Haushalte bei Gas-, Wärme- und Strombezug diskutiert. Wie eine Gaspreisbremse ausgestaltet sein soll - für jede Gaskundschaft im...

We report on an economic experiment that compares outcomes in electricity markets subject to carbon-tax and cap-and-trade policies. Under conditions of uncertainty, price-based and quantity-based policy instruments cannot be truly equivalent, so we compared three matched carbon-tax/cap-and-trade...

Der verbraucherzentrierte Strommarkt ist das neue Paradigma in der Strommarktregulierung. Kleine Akteure wie Prosumenten und Energiegemeinschaften werden wichtig und zwingen dazu, die aktuellen Vermarktungswege für Strom auf den Prüfstand zu stellen. Diese Arbeit widmet sich innovativen...

In recent years the analysis of US climate policy on the electricity sector has predominantly deployed electricity planning or capacity expansion models that use deterministic or equilibrium optimization methods. While uncertainty in key input assumptions is considered, it is usually restricted...
