Environmental taxation and structural change in an open economy: a CGE analysis with imperfect competition and free entry
Böhringer, Christoph; Welsch, Heinz; Löschel, Andreas - 2001
The economic effects of environmental taxes depend on the market structure. Under imperfect competition with free entry and exit, environmental taxes have an impact on economies of scale by changing the number and size of firms. Whether economies of scale rise or fall in a particular industry...

Idiosyncratic risk and the cost of capital: The case of electricity networks
Schober, Dominik; Schäffler, Stephan; Weber, Christoph - 2014
We analyze the treatment and impact of idiosyncratic or firm-specific risk in regulation. Regulatory authorities regularly ignore firm-specific characteristics, such as size or asset ages, implying different risk exposure in incentive regulation. In contrast, it is common to apply only a single...

Incentive regulation: Evidence from German electricity networks
Hellwig, Michael; Schober, Dominik; Cabral, Luís - 2019
We propose a difference-in-differences (DiD) approach to estimate the impact of incentives on cost reduction. We show theoretically, and estimate empirically, that German electricity distribution system operators (DSOs) pile up more costs in the year used to determine future prices when subject...
