Revisiting the Relatedness Hypothesis: The Impact of Merger Relatedness on Acquiring and Rival Firm Value  

Despite intuitive appeal, empirical evidence supporting the relatedness hypothesis has been scant, as it has not been established that related acquisitions generally outperform unrelated acquisitions.

Heating and Electricity Expenses: Saving Incentives Not Impacting Basic Income Recipients

Basic income benefits cover recipients’ actual heating expenses as long as they are not unusually high. In contrast, their electricity expenses are only covered via a lump sum at the standard rate. Thus, basic income recipients have weaker incentives for reducing their heating expenses than for reducing their electricity expenses. Using Socio-Economic Panel (SOEP) data, it can be seen that basic income ...

Basic income households spend more on heating and electricity than comparable households

The Economic Determinants of Bitterness – Evidence from Plant Closures in Germany

-- joint with Panu Poutvaara and Max Steinhardt This study analyzes the determinants of bitterness, which describes a feeling of not having achieved what one deserves compared to others.

Terrorism and Voting: The Rise of Right-Wing Populism in Germany

-- joint with Marius Liebald and Guido Friebel Can right-wing terrorism increase support for far-right populist parties and if so, why? Exploiting quasi-random variation between successful and failed attacks across German municipalities, we find that successful attacks lead to significant increases in the vote share for the right-wing, populist Alternative für Deutschland (AfD) party in state...
