This paper studies a game of strategic experimentation in which the players have access to two-armed bandits where the risky arm distributes lumpsum payoffs according to a Poisson process with unknown intensity. Because of free-riding, there is an inefficiently low level of experimentation in...

We study optimal experimentation by a monopolistic platform in a two-sided market. The platform provider is uncertain about the strength of the externality each side is exerting on the other. Setting participation fees on both sides, it gradually learns about these externalities by observing...

The electorates' lack of information about the extent of public spending may cause misalignments between voters' preferences and the size of government. We devise a series of representative survey experiments in Germany that randomly provide treatment groups with information on current spending...

To study whether current spending levels and public knowledge of them contribute to transatlantic differences in policy preferences, we implement parallel survey experiments in Germany and the United States. In both countries, support for increased education spending and teacher salaries falls...

Peoples' willingness to vaccinate is critical to combating the COVID-19 pandemic. We devise a representative experiment to study how the design of the vaccine approval procedure affects public attitudes towards vaccination. Compared to an Emergency Use Authorization, choosing the more thorough...

Large, macroeconomic shocks in the past have been shown to influence economic decisions in the present. We study in an experiment with 743 subjects whether small-scale, seemingly negligible, events also affect the formation of risk preferences. In line with a reinforcement learning model, we...

Gender gaps in labor-market outcomes often emerge with arrival of the first child. We investigate a causal link between gender norms and labor-supply expectations within a survey experiment among 2,000 German adolescents. Using a hypothetical scenario, we document that most girls expect to work...

Public preferences for charging tuition are important for determining higher education finance. To test whether public support for tuition depends on information and design, we devise several survey experiments in representative samples of the German electorate (N19,500). The electorate is...

A large literature studies subjective beliefs about economic facts using unincentivized survey questions. We devise randomized experiments in a representative online survey to investigate whether incentivizing belief accuracy affects stated beliefs about average earnings by professional degree...

The standard assumption of exogenous policy preferences implies that parties set their positions according to their voters' preferences. We investigate the reverse effect: Are the electorates' policy preferences responsive to party positions? In a representative German survey, we inform...
