Decarbonization requires the transformation of power markets towards renewable energies and investment costs are decisive for the deployed technologies. Exogenous cost assumptions cannot fully reflect the underlying dynamics of technological change. We implement divergent learning-by-doing...

Energy system and power market models refrain from distinguishing between private and social discount rates. We devise a strategy to account for diverging private and social discount rates in intertemporal optimization frameworks, resulting in an optimal carbon tax above the marginal damage when...

Current decarbonization policies neglect damages from local air pollutants. We analyze the trade-off between complementary taxation of carbon emissions and local air pollution. We quantify results for the European power market until 2050. Taxing only air pollution results in social cost of 5,890...

Current policies focus on reducing CO2 emissions, neglecting the existence and impact of other air pollutants such as NO2, NH3, NMVOC, PPM10, PPM2.5, and SO2. We devise a strategy to model those emissions and related social cost accounting for diverging social and private discount rates in an...

Die nationalen Shutdowns, ausgelöst durch die Corona-Pandemie, führten zum Einbruch der wirtschaftlichen Aktivität in Europa. Unter anderem gingen die Treibhausgasemissionen in Europa aufgrund des Stillstands von Produktionsanlagen und einer gesunkenen Stromnachfrage deutlich zurück. Dies...

The EU implemented the Market Stability Reserve (MSR) in response to the 2008 financial crisis to deal with short-term impacts of future shocks, such as the COVID-19 pandemic. We link a model that intertemporally optimizes the handling of banked allowances every five years with one that...

Bottom-up optimization models neglect the inclusion of investment behavior We introduce three investor types that differ in their investment cost specifications, financing costs, and discounting. This leads to a substantially different pace and rate of adoption for specific generation...

Policymakers misjudge results of technology-rich optimization models because those models specify investment cost differently and thus are not equally sensitive towards changing financing cost and discount rates. We apply an intertemporally optimizing power market model to analyze three...

Detailed numerical models of power markets with millions of variables and equations are often perceived as black boxes, because differences in results cannot be traced back to single equations or assumptions, respectively. We unravel parts of those black box by determining the impact of...

Was bringt die Europäische Union (EU) dem Wirtschaftsstandort Deutschland? Dieser Beitrag berechnet anhand unterschiedlicher politischer Szenarien den Vorteil in Form von geringeren Strom- und CO2-Preisen einer europäischen Kooperation beim Klimaschutz sowie beim Ausbau des internationalen...
