Affirmative action to promote women's employment is a intensely debated policy. Do affirmative action policies attract women and does it come at a cost of deterring high qualified men? In three field experiments in Colombia we compare characteristics of job-seekers who are told of the...

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...

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...

Building on theoretical and empirical literatures showing that choices not only reflect but also create preferences, we develop a two-stage incentivized intervention to promote pro-sociality. In the first stage, participants are incentivized to complete a compound task consisting of a targeted...

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...

We study how defaults affect charitable donations. In a field experiment that was conducted on a large online platform for charitable giving, we exogenously vary the default options in the donation form in two distinct choice dimensions. The first pertains to the primary donation decision,...

The literature on pro-social behavior shows that older children are more generous than younger children; however, the level of individual generosity is heterogeneous even between children of the same age. This paper investigates whether a child’s popularity affects a child’s generosity. Our...

We document the effectiveness of robo calls for increasing voter participation despite most published research finding little or no effect of automated calls. We establish this finding in a large field experiment in a targeted, partisan get-out-the-vote campaign. Our experimental design includes...

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...

While many companies use algorithms to optimize their pricing, additional human oversight and price interventions are widespread. Human intervention can correct algorithmic flaws and introduce private information into the pricing process, but it may also be based on less sophisticated pricing...
