Cities increasingly address climate change, e.g. by pledging city-level emission reduction targets. This is puzzling for the provision of a global public good: what are city governments' reasons for doing so, and do pledges actually translate into emission reductions? Empirical studies have...

We show that the electorate’s preferences for using tuition to finance higher education strongly depend on the design of the payment scheme. In representative surveys of the German electorate (N18,000), experimentally replacing regular upfront by deferred income-contingent payments increases...

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...

We conduct an experiment in which groups are tasked with evaluating the truth of a set of politically relevant facts and statements, and we investigate whether communication improves information aggregation and the accuracy of group decisions. Our findings suggest that the effect of...
