Randomized experiments are often viewed as the "gold standard" of scientific evidence but people's scepticism towards experiments has compromised their viability in the past. We study preferences for experimental policy evaluations in a representative survey in Germany (N1,900). We find that a...

Much of today’s software relies on programming code shared openly online. Yet, it is unclear why volunteer developers contribute to open-source software (OSS), a public good. We study OSS contributions of some 22,900 developers worldwide on the largest online code repository platform, GitHub,...

This paper studies the effects of the high-speed internet expansion on the match quality of new hires. They combine data on internet availability at the local level with German individual register and vacancy data. Results show that internet availability has no major impact on the stability of...

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...

To what extent does a more competent public bureaucracy contribute to better economic outcomes? We address this question in the context of the US federal procurement of services and works, by combining contract-level data on procurement performance and bureau-level data on competence and...

Practitioners and scholars of public administration currently seem to have overcome comprehensive reform strategies and are focusing their attention on minor changes in public administration that generate short-term outcomes with lower transactional costs. In that sense, many have argued that...

We investigate the long-run effects of government surveillance on civic capital and economic performance, studying the case of the Stasi in East Germany. Exploiting regional variation in the number of spies and administrative features of the system, we combine a border discontinuity design with...

Voters dealing with jurisdictional merger decisions face a trade-off between economies of scale and preference costs. Larger jurisdictions may offer cost advantages, yet the downside is that policies in larger units may be less aligned to voter preferences. Our study is the first to provide...

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...
