During 2022, about eight million Ukrainians were displaced from Ukraine due to the Russian invasion. Whether these individuals will return holds great significance for Ukraine's reconstruction and is pivotal in shaping integration strategies in host countries. We used Facebook ads to recruit a...

We exploit the unique design of a repeated survey experiment among students in four countries to explore the stability of risk preferences in the context of the COVID-19 pandemic. Relative to a baseline before the pandemic, we find that self-assessed willingness to take risks decreased while the...

Immigration is one of the most divisive political issues in many countries today. Competing narratives, circulated via the media, are crucial in shaping how immigrants’ role in society is perceived. We propose a new method combining advanced natural language processing tools with dictionaries...

We provide novel evidence of how an innovative market-based solution using remote-sensing technology can mitigate conflict. Droughts are a major driver of conflict in Africa, particularly between nomadic pastoralists and sedentary farmers, and climate change is predicted to intensify this...

Understanding behavioral aspects of collective decision-making is an important challenge for eco-nomics, and narratives are a crucial group-based mechanism that influences human decision-making. This paper introduces the Character-Role Narrative Framework as a tool to systematically analyze...

We investigate the effects of short-term political motivations on the effectiveness of foreign aid. Donor countries' political motives might reduce the effectiveness of conditionality, channel aid to inferior projects or affect the way aid is spent in other ways, reduce the aid bureaucracy's...

The quasi-exogenous division of the French regions Alsace and Lorraine after the Franco-Prussian War allows us to provide evidence about group identity formation within historically homogeneous regions. Using several measures of stated and revealed preferences spanning over half a century, we...

We exploit the fact that disagreements in the German leadership after the Franco-Prussian War in 1870 led to a quasi-exogenous division of Alsace and Lorraine to provide rare evidence of group identity formation within historically homogeneous regions. In line with the rejection-identification...

There is little causal evidence about deep-rooted sources of support for shifting power from nation-states to international organizations. Focusing on the European Union, this paper develops the hypothesis that citizens appreciate the role of international organizations in constraining...

China’s development model challenges the approaches of traditional Western donors like the World Bank. We argue that both aim at stability, but differ in the norms propagated to achieve that. Using fixed effects and IV estimations, we analyze a broad range of subnational stability measures in...
