The transformation of the electricity sector is a central element of the transition to a decarbonized economy. Conventional generators powered by fossil fuels have to be replaced by variable renewable energy (VRE) sources in combination with electricity storage and other options for providing temporal flexibility. We discuss the market dynamics of increasing VRE penetration and its integration in the ...
Different options for a reform of the EU Emissions Trading System are discussed to ensure carbon price incentives for mitigation options in the basic materials sector, while minimizing carbon leakage risks. This paper quantifies carbon leakage risks, distributional implications, and additional revenues associated with an import-only border carbon adjustment (BCA), a symmetric (import and export) BCA, ...
Introduced 20 years ago as a part of the 2001 pension reform, the Riester pension is meant to function as an essential component of the German pension system with the aim of compensating for decreasing public pensions. However, data collected by the SOEP show that this objective has not yet been achieved. For ten years, use of the Riester pension plan has been stagnating at around 25 percent of the ...
Single mothers often experience precarious financial conditions. However, it is not fully understood to what extent separation is the cause of these conditions versus being their consequence. Estimating an endogenous switching regression model based on a sample of 626 separated and 5,525 non-separated mothers drawn from the German Socio-Economic Panel (SOEP) 1984-2018, we disentangle the roles of causation ...
To decarbonize the economy, many governments have set targets for the use of renewable energy sources. These are often formulated as relative shares of electricity demand or supply. Implementing respective constraints in energy models is a surprisingly delicate issue. They may cause a modeling artifact of excessive electricity storage use. We introduce this phenomenon as 'unintended storage cycling', ...
