Smartphone app designers often use behavioral design to influence users, increase sales, and boost advertising revenue. Behavioral design relies on elements ranging from app appearance to black-box algorithms and personalization. It commonly exploits behavioral biases, such as the lack of...

I estimate permanent and transitory tax-price and income elasticity of charitable giving in Germany using a rich panel data of tax return for the years 2001-2006. Income tax reforms were implemented in 2004 and 2005. The results suggest that the permanent tax-price elasticity varies...

When asking for donations, charitable organizations often use suggestions concerning the amount of potential contributions. However, the evidence concerning the effects of such suggestions is scarce and inconsistent. Unlike the majority of existing studies concerned with small-money...

How far can the media protect or undermine democratic institutions in unconsolidated democracies, and how persuasive can they be in ensuring public support for dictator's policies? We study this question in the context of Germany between 1929 and 1939. Using geographical and temporal variation...

How do the media affect public support for democratic institutions in a fragile democracy? What role do they play in a dictatorial regime? We study these questions in the context of Germany of the 1920s and 1930s. During the democratic period, when the Weimar government introduced progovernment...

Is there a way of matching donations that avoids crowding out? We introduce a novel matching method where the matched amount is allocated to a different project, present some simple theoretical considerations that predict reduced crowding out or more crowding in (depending on the degree of...

Is there a way of matching donations that avoids crowding out? And, more generally, what is the best way to utilize a bigger lead gift for raising smaller contribu-tions in a fundraising campaign? To answer these questions, we present a novel matching method, some simple theoretical...

We study intertemporal crowding between two fundraising campaigns for the same charitable organization by manipulating donors' beliefs about the likelihood of future campaigns in two subsequent field experiments. Theory predicts that the effect of such belief manipulations depends on whether...

In a n experiment, we test the impact of quality certificates on donation s to a charity. Compared to the control group, participants presented with a quality certificate chose higher donations by around 10% and reported higher trust towards the same charity . The choice of donation values over...

We study intertemporal crowding between two fundraising campaigns for the same charitable organization by manipulating donors' beliefs about the likelihood of future campaigns in two subsequent field experiments. The data shows that initial giving is decreasing in the likelihood of a future...
