This paper presents the result of a field experiment on the effectiveness of non-monetary incentives on pupils' achievement on a mathematical multiple choice test. Our sample consists of 2113 pupils of deprived and high-achieving secondary schools in Germany. Based on a pre-study, we compare the...

In this paper, we systematically analyze the empirical importance of standard conditions for the validity and generalizability of field experiments: the internal and external overlap and unconfoundedness conditions. We experimentally varied the degree of overlap in disjoint sub-samples from a...

This paper investigates how framing manipulations affect the quantity and quality of decisions. In a field experiment in elementary schools, 1.377 pupils are randomly assigned to one of three conditions in a multiple-choice test: (i) gain frame (Control), (ii) loss frame (Loss) and (iii) gain...

Lack of information about COVID-19 and its spread may have contributed to excess mortality at the pandemic's onset, In April and May 2020, we implemented a randomized controlled trial with more than 3,000 households in 150 Bangladeshi villages, Our one-to-one information campaign via phone...

We study individuals who can choose how to compete with an opponent for one nonzero payoff. They can either nudge themselves into a fair set of rules where they have the same information and actions as their opponent, or into unfair rules where they spy, sabotage or fabricate their opponent's...

We study how other-regarding behavior extends to environments with uncertain income and conditional commitments. Should fundraisers ask a banker to donate "if he earns a bonus" or wait and ask after the bonus is known? Standard EU theory predicts these are equivalent; loss-aversion and signaling...

Gender equity in the creation and enforcement of social norms is important not only as a normative principle but it can also support long term economic growth. Yet in most societies, coercive power is in the hands of men. We investigate whether this form of segregation is due to gender...

Focusing theory hypothesizes a bias toward concentration according to which consumers prefer goods with one outstanding feature over those with several smaller sized upsides. In contrast to models of present-biased behavior, focusing theory prescribes also future-biased behavior if an option's...

This paper explores whether loss aversion applies to social image concerns. In a simple model, we combine loss aversion in social image concerns and attitudes towards lying. We then test its predictions in a laboratory experiment. Subjects are first ranked publicly in a social image relevant...

Ambiguous language is ubiquitous and often deliberate. Recent theoretical work (Beauchêne et al., 2019; Bose and Renou, 2014; Kellner and Le Quement, 2018) has shown how language ambiguation can improve outcomes by mitigating conflict of interest. Our experiment finds a significant effect of language...
