In a randomized controlled trial involving 700 obese persons assigned to three experimental groups, we test whether financial incentives have heterogeneous effects on weight reduction. While two treatment groups obtain EUR 150 and EUR 300, respectively, for achieving an individually-assigned...

We test whether financial incentives have an effect on weight reduction in a randomized controlled trial involving 700 obese persons assigned to three experimental groups. While two treatment groups obtain €150 and €300, respectively, for achieving an individually assigned target weight...

Deforestation and burning of forest products to meet cooking needs massively contribute to global warming. In order to reduce the biomass fuel consumption of households in developing countries, various improved cookstove (ICS) interventions were implemented by governments, NGOs, and other...

This paper presents the findings of two Randomized Controlled Trials (RCTs) that were conducted in collaboration with the Australian Taxation Office (ATO). The first trial tests the effect of changes to letters (timing, social norms, color, and provision of information about charitable...

Very little is known about the compliance behavior of first-time taxpayers although their tax paying habits may affect the long-run functioning of a tax system. This paper studies the compliance behavior of new entrants to the tax system using data from a large-scale natural field experiment...

Massive Open Online Courses are a promising educational innovation. Yet, they suffer from high drop-out rates. As a remedy, we propose a planning prompt and test its effect on course completion and further outcomes such as course engagement and satisfaction in four large-scale randomized...

Many policy interventions in the environmental sector aim at changing environmental preferences, because these provide the basis for adopting environmental conservation behavior or technologies. To evaluate these changes, standard measurement tools in survey-based impact evaluations have their...
