We discuss the implications of two price zones, i.e. one northern and southern bidding area, on the German electricity market. In the northern zone, continuous capacity additions with low variable costs cause large regional supply surpluses in the market dispatch while conventional capacity...

We analyze the pass-through of cost changes to retail tariffs in the German electricity market over the 2007 to 2014 period. We find an average pass-through rate of around 60%, which significantly varies with demand factors: while the pass-through rate to baseline tariffs, where firms have...

This paper, which is one of the first to estimate productivity in retail electricity for a European country after liberalisation, analyses the effect of ownership and governance structure by using a unique dataset of German electricity retailers from 2003 to 2012. An innovative service...

This paper investigates the impacts of the eastern enlargement of the European Union in 2004 and the liberalisation of European electricity markets on Germanys electricity exchange with neighbouring countries and on electricity prices. Thus, electricity imports from Czech Republic have increased...

Power systems with increasing shares of wind and solar power generation have higher capital and lower operational costs than traditional technologies. This increases the importance of the cost of finance for total system cost. We quantify how renewable policy design can influence cost of finance...

This paper evaluates the effects of liberalizing access to the space sector, as currently envisaged by the EC Commission. We undertake an econometric evaluation of the degree of scale economies in satellite operations and calibrate a Cournot model of competition in which the effect of...

This paper develops a model of successive oligopolies with endogenous market entry, allowing for varying degrees of product differentiation and entry costs in both markets. Our analysis shows that the downstream conditions dominate the overall profitability of the two-tier structure while the...

Restructuring electricity markets has enabled wholesalers to exercise market power. Using a common method of measuring competitive behavior in these markets, several studies have found substantial inefficiencies. This method overstates actual welfare loss by ignoring production constraints that...
