Effects of renewable support legislation on electricity prices have been analyzed with a plethora of models. However, these models neglect at least one of the following aspects which we take into account in our analysis: oligopolistic market behavior of dominant firms, emission trading,...

We use a quantitative electricity market model to analyze the welfare effects of refunding a share of the emission trading proceeds to support renewable energy technologies that are subject to experience effects. We compare effects of supporting renewable energies under both perfect and...

For many years now, nitrate concentrations have exceeded the trigger value of 50 milligrams per liter at nearly one-fifth of the groundwater sampling sites in Germany. Apart from impairing the ecosystem by, for example, causing eutrophication of water bodies, nitrate-polluted drinking water also...

The effects of the climate crisis are worsening water shortages, not only in the Global South but also in Europe, for example in the Berlin-Brandenburg region. Due to inadequate pricing of surface and groundwater abstraction and a lack of regulatory instruments, water overuse is occurring in...

Under perfect competition on the output market, first best technology subsidies in the presence of learning by doing are justified by knowledge spill overs that are not accounted for by individual companies. First best output subsidies are thus depending directly on the learning effects and are,...
