Carbon emissions from German manufacturing have increased over the past decade, while carbon intensity (emissions per Euro of gross output) has declined only slightly. We decompose changes in emissions between 2005 and 2017 into scale, composition (changes in the mix of goods produced) and...

Electricity generation based on renewable energy (RE) sources such as wind and solar replace the most expensive generators that often rely on fossil fuels. In response to RE promotion, wholesale electricity prices and carbon emissions are therefore expected to decrease. In interconnected...

The cost and revenue earnings potential of alternative power generation sources has shifted considerably in recent years. Here we introduce the concept of Levelized Profit Margins (LPM) to capture the changing unit economics of both intermittent and dispatchable generation technologies. We apply...

This paper proposes a game-theoretic model to analyze the strategic behavior of inc-dec gaming in market-based congestion management (redispatch). We extend existing models by considering incomplete information about competitors’ costs and a finite set of providers. We find that these...

Climate policy often implies increasing energy prices. Due to incomplete regulation across the globe, concerns about their competitiveness and employment effects play an important role in the policy debate. Using micro-data on electricity network charges and the official census data for Germany,...

This paper examines how optimal renewable energy (RE) support (RES) policies need to be adjusted to account for carbon prices. We show theoretically and empirically that changing carbon prices requires adjusting RE production subsidies due to two different motives: First, RE premiums need to be...

The pace of the global decarbonization process is widely believed to hinge on the rate of cost improvements for clean energy technologies, in particular renewable power and energy storage. This paper adopts the classical learning-by-doing framework of Wright (1936), which predicts that cost will...

In the advent of postal market liberalization in several European countries we expect that the incumbent operators anticipate entry by competitors who are not required to offer universal service, i.e. coverage of the entire country and uniform pricing. The market for postal service exhibits...

Under ex ante access regulation entrants often claim that access fees are excessive. I show that this is only the case if further entry is admitted. If the entrant is protected from further entry it would agree with the incumbent upon a strictly positive access fee which may exceed the efficient...

Central features of today's electronic communications markets are complementarities between the different layers of the value chain, substitutability between some applications, network effects in the provision of content and services, two-sided business models that partly involve indirect...
