The EU member states have declared to strongly increase the share of Renewable Energy Sources in the next decades. Given a large deployment of wind and solar capacities as well as limited cost-efficient storage technologies, this has two major impacts on electricity systems. First, the...

A major concern in climate negotiations is that decarbonization may significantly hurt the development process. This paper shows that international specialization can contribute to making environmental and economic objectives compatible. When carbon efficiency differs between two trading...

We examine the distributional and efficiency impacts of climate policy in the context of fiscal consolidation in a dynamic general-equilibrium overlapping generations model of the US economy. The model includes a disaggregated production structure, including energy sector detail and advanced...

Urban renewal areas are popular instruments in spatial planning to prevent urban decline and to induce urban renewal. 22 renewal areas were implemented in Berlin, Germany alone between 1993 and 1995, mainly to increase housing and living quality in the aftermath of the city s long division...

We use a quasi-experimental research design to study the effects of 22 renewal areas implemented in Berlin, Germany, to increase housing and living quality in the aftermath of the city s division during the Cold War period. Our results suggest within the targeted areas that the policy has helped...

We study education and income tax policies in a model with endogenous selection into college. Our framework is strongly influenced by the empirical college literature and incorporates heterogenous returns and tastes for college, earnings risk (implying uncertain returns to college) and...

Numerous studies analyze gender wage differences focusing on gross hourly wages. The analysis of differences in gross wages allows statements on productivity differences between men and women and to quantify the unexplainable wage gap which is often attributed to discrimination. While there is...

The Great Recession and the resulting European debt crisis revived a debate about deeper fiscal integration in the Eurozone. We discuss different alternatives how an unemployment insurance system for the euro area could be designed and run counterfactual simulations based on micro data to...

The paper studies optimal income taxation in a model with labor supply responses at the intensive and the extensive margin. It is shown that a utilitarian desire for redistribution does not pin down the sign of the optimal marginal tax rate: labor supply may be downward distorted, undistorted,...
