TY - RPRT A1 - Traxler, Christian A1 - Linek, Maximilian T1 - Framing and Social Information Nudges at Wikipedia N2 - We analyze a series of trials that randomly assignedWikipedia users in Germany to different web banners soliciting donations. The trials varied content or framing of social information about how many other users are donating. Framing of a given number of donors in a negative way increased donation rates. Variation in social information had no detectable effects. The findings are consistent with the results from a survey experiment. In line with donations being strategic substitutes, the survey documents that the negative framing lowers beliefs about others’ donations. In contrast, the provided social information is ineffective in changing average beliefs. The ineffectiveness seems to be due to the limited salience rather than the limited credibility of the social information.

The choice environment is the setting within which an individual makes her decision. It is widely acknowledged that even inconspicuous changes to this environment can have strong effects on behavior. This notion has spurred large efforts in the public and private sector to design these environments and steer behavior. The dissertation studies four measures that change choice environments to achieve public and private objectives. The first chapter investigates the effects of community meetings on behavior changes that were desired by the central government in Rwanda. It studies these effects with and without performance incentives for local leaders and sheds light on who controls meetings and how they operate. The second chapter studies expected effects of Basic Income on time use, deploying a large-scale survey experiment. The results show intended reallocations that may contribute to foster social cohesion in society. In addition, the chapter suggests its methodology as a new approach to explore policies that are difficult or costly to test. Finally, the third and fourth chapter study the effects of social information and defaults in online donations. The third chapter shows that the empirical regularity of conditional cooperation fails. The fourth and last chapter explores the complex relationship between different numbers and values of donation amount defaults.
