The "true" size of fiscal multipliers is widely debated by economists and policy makers as large (small) multipliers provide arguments to expand (cut) public spending. Within a meta-analytical framework, we ask whether the large observed variance in multiplier estimates can be explained by the...

To study how information about educational inequality affects public concerns and policy preferences, we devise survey experiments in representative samples of the German population. Providing information about the extent of educational inequality strongly increases concerns about educational...

German separation in 1949 into a communist East and a capitalist West and their reunification in 1990 are commonly described as a natural experiment to study the enduring effects of communism. We show in three steps that the populations in East and West Germany were far from being randomly...

In business and politics, gifts are often aimed at influencing the recipient at the expense of third parties. In an experimental study, which removes informational and incentive confounds, subjects strongly respond to small gifts even though they understand the gift giver’s intention. Our...

Talk about global democracy seems to be fixated on a Reform-Act model of democracy, with 'one person one vote for all affected by the decisions' as for example in a second popularly-apportioned chamber of UN. Politically, that seems wildly unrealistic. But remember that the Reform Acts came very...

This paper summarizes previous results on the productivity of public capital. In recent literature, Aschauer's (1989) estimate for the productivity of public capital is often considered too high and the size of the effect is still open to debate. However, the positive effect of public capital on...

We explore the role of social capital in the spread of the recent Covid-19 pan­demic in independent analyses for Austria, Germany, Italy, the Netherlands, Swe­den, Switzerland and the UK. We exploit within-country variation in social capital and Covid-19 cases to show that high-social-capital...

The end of communism in the 1990s probably is the most fundamental restructuring of institutions witnessed in recent history. At its core was the large-scale redistribution of previously state-owned companies. We construct a unique firm-level dataset to study this redistribution in East Germany...
