International carbon markets are frequently propagated as an efficient instrument for reducing CO2 emissions. We argue that such markets, despite their desirable efficiency properties, might not be in the best interest of governments who are guided by strategic considerations in negotiations. We...

This paper provides formulas for optimal top marginal tax rates when couples are taxed according to income splitting between spouses, consumption is taxed, and the skill distribution is unbounded. Optimal top marginal income tax rates are computed for Germany using a dataset that includes the...

This paper studies the existence of election cycles in public procurement in the European Union for the national level. We analyze different steps along the procurement process, namely the publication of the contract notice, the awarding of the contract, and the project completion. We point out...

We present the first comprehensive evidence on the role of cognitive ability and personality traits in the selection of electoral candidates and election of politicians. Using unique data that combine population registers and election statistics from local government elections in Finland with...

Laboratory evidence shows that when people have to argue for a given position, they persuade themselves about the position’s factual and moral superiority. Such self-persuasion limits the potential of communication to resolve conflict and reduce polarization. We test for this phenomenon in a...

Using new survey and experimental data for a representative sample of the German population, we study preferences for tax simplification. The general wisdom seems to suggest that most tax systems are overly complex and that tax simplification is generally desirable. Consistent with this general...

This paper studies whether political budget cycles occur in public procurement in the European Union. Using project- level data from Tenders Electronic Daily (2008-2018), I analyze different steps along the procurement process, namely the publication of the contract notice, the awarding of the...

We study reforms of non-linear income tax systems from a political economy perspective. We present a median voter theorem for monotonic tax reforms, reforms so that the change in the tax burden is a monotonic function of income. We also provide an empirical analysis of tax reforms, with a focus...

We study the interaction of climate policies and investments into fossil and renewable energy generation capacity if policies are set by democratically elected governments and can lead to stranded assets. We develop an overlapping generations model, where elections determine carbon taxation and...
