Equality of opportunity is an important normative ideal that concerns politicians and the larger public alike. In spite of its wide acceptance, current estimation approaches in the literature suffer from severe data restrictions that lead to biased estimates of inequality of opportunity. These...

The Covid-19 pandemic has led to an increase in public debt in most countries. This will increase fiscal pressure in the future. We study how the shape of the optimal nonlinear income tax schedule is affected by this increase in fiscal pressure. We calibrate the workhorse optimal income tax...

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...

We apply Open Street Map to identify available placement cells and Global Wind Atlas to determine average wind speeds on a 500 x 500m grid in Germany (1.3 million cells). Minimum distances to obstacles such a roads and buildings leave 535,000 potential placement cells. We calculate...

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...

Climate policy instruments in the transportation sector like fuel economy standards (CAFE) and fuel taxes not only affect households' vehicle choice, but also the urban form in the long run. We introduce household level vehicle choice into the urban economic monocentric city model and run...

At what rate should a government price carbon emissions? This paper analyzes optimal carbon pricing while taking into account interactions with the taxation of labor and capital income. In an otherwise standard climate-economy model, the policy maker has to resort to a distortionary tax on labor...
