Tax compliance nudges are used increasingly by governments because of their perceived cost-effectiveness in raising tax revenue. We collect about a thousand treatment effect estimates from 45 randomized controlled trials, and synthesize this rapidly growing literature using meta-analytical...

We examine optimal incentives for charitable giving with a large-scale field experiment involving 26 charities and over 112,000 unique individuals. The price of giving is varied by offering a fixed match if the donation meets a threshold amount (e.g. "give at least $25 and the charity receives a...

This paper studies the impact of "nudges" on taxpayers with varying tax compliance histories in Papua New Guinea. We present the results from two population-wide randomized controlled trials in a setting that is characterized by low compliance rates and a lack of effective enforcement. We test...

Individuals often desire to achieve certain outcomes, but potentially lack the procedural knowledge on how to do so. This study provides causal evidence that imperfect procedural knowledge is a severe obstacle to efficient behavior, but can be overcome by providing low-cost information. I...

Higher order risk preferences are well-known for their relation with precautionary saving or portfolio allocation. Theoretically, they are also connected with other important behavior, such as health-related or eco-friendly behavior, but these relations have never been investigated with field...

The civil war in Syria has been raging since 2011. We ask whether civil war experience affects voluntary cooperation and its coordination by means of peer punishment. To answer that question, we ran experiments with Syrians and Jordanians, and use a victimization index to measure the individual...

In this paper, we show that the right to determine the sequence of moves in a dynamic team tournament improves the chances of winning the contest. Because studying dynamic team tournaments - like R&D races - with interim feedback is difficult with company data, we examine decisions of highly...

We use a novel method to elicit and measure higher order risk preferences (prudence and temperance) in an experiment with 658 adolescents. In line with theoretical predictions, we find that higher order risk preferences - particularly prudence - are strongly related to adolescents' field...
