In this study, we conduct a dictator game experiment with face mask wearers and non-mask wearers in Japan, and ascertain allocation tendencies between two anonymous individuals, between two mask wearers or two non-mask wearers, and between a mask wearer and a non-mask wearer. By so doing, we assess “ingroup-favoritism,” “ingroup bias,” and “outgroup bias” of the mask wearers and non-mask wearers, respectively. Here, ingroup-favoritism is defined as the difference between the money amounts allocated in the dictator game experiment to an individual of the same group (i.e., a recipient who wears a mask for the mask wearers and a recipient who does not wear a mask for the non-mask wearers) and to an individual of the different group (i.e., a recipient who does not wear a mask for the mask w...
I study the role of ambiguity preferences in predicting take-up of algorithmic (i.e., personalized) recommendations. In a two-part experiment, I first elicit individuals's preferences towards risk and ambiguity. In Part 2, I ask participants to make choices over a menu of risky prospects after I provide a recommendation (or not) based on their treatment assignment. I assign individuals to one of two control groups (no recommendation or randomly created recommendation) or to one of two treatment groups (personalized recommendation with no information or personalized recommendation with information). The difference between the two treatments is only the information provided to individuals on how the recommendation is constructed; both recommendations are of similar quality (i.e., based on...
We conduct large-scale surveys of Italian citizens and information treatments about a very large EU-financed transfer scheme (the Next Generation EU) to understand a) if and why there exists a gender gap in policy literacy and b) how policy knowledge affects trust and attitudes towards the EU. In the first part of the analysis, we want to understand whether women are more or less informed than men, if so, whether the gaps are driven by differences in confidence or actual knowledge gaps. We also aim to test whether women respond differently to communication about the program based on the type of information they receive. To do so, we field a survey assessing policy knowledge regarding the Next Generation EU and conduct a survey experiment where we randomize the availability of "I Don...
This project studies how the coarseness of moral categories affects moral behavior.
This project works directly with the government of Punjab, Pakistan to improve the effectiveness of public procurement. We develop two novel methods to measure procurement effectiveness and leakages based on detailed, item-level characteristics data and random field audits of purchases. We then implement a field experiment to study how these are affected by two policy reforms targeting bureaucrats’ extrinsic and intrinsic motivations to achieve value for money in procurement. The first treatment awards financial bonuses for good procurement performance. The second treatment empowers bureaucrats to exercise discretion in procurement to achieve better value for money by giving them a larger cash-in-hand budget, making pre-audit procedures simpler and more predictable, and releasing their ...

In poor neighborhoods across Latin America, one of the largest social organizations is the street gang. They are often the largest employer in the neighborhood, especially of poor adolescent boys. It’s striking, then, how little we understand these firms and, most importantly, the decision-making process of young recruits. Medellin, Colombia, has hundreds of well-organized street gangs. We have partnered with the Secretariat of Education to conduct a population-based survey of two cohorts of grade 7 boys. We intend to conduct the surveys in roughly half of Medellin’s 200 public schools, and anticipate that roughly 10,000 boys will participate. In addition to measuring a variety of risk factors and preferences, the survey measures boys’ expectations of the pecuniary and non-pecuniary ret...
The goal of this project is to evaluate the impact of institutions promoting diversity in a controlled environment. The motivation for the study stems from concerns about diversity in academia, and specifically gender diversity, that appears particularly difficult to achieve. We want to explore whether institutions promoting gender diversity may or may not promote diversity of ideas in a world where there are gender differences in taste and expertise for certain fields, leading to some fields being more appealing to men and others to women. If there is an incentive to hire women, preference may be given to women, but possibly mostly those in male fields. As a consequence, institutions promoting gender diversity may achieve more gender diversity but not necessarily more diversity of id...

The proposed randomized control trial is designed to study the effect of nutrition and gender sensitive messaging embedded in the work of extension workers across four regions of Ethiopia. All kebeles in our sample are provided video-based agricultural content presented by agricultural extension workers. In randomly selected kebeles, these videos will be presented in a framing that encourages collaboration in the household and promotes women to be active participants in household decision-making. A subset of the kebeles in the collaboration arm will be randomly selected to also be provided with video-based agricultural extension that explicitly focuses on connecting agricultural decisions to improving nutrition outcomes in the household. The evaluation contributes to the literature by ...
