Recent work shows that worker responses to peer information are heterogeneous, depending on workers' information preferences and their relative earnings position from peers (Lim, 2025, 2026). I conduct a follow-up field experiment with the same sample of around 2,900 rideshare drivers to test whether targeting who receives peer information and which peer benchmark each worker observes can amplify the labor supply gains from peer-information disclosure in the workplace. Over a six-week intervention, drivers are randomly assigned to one of three information arms: no peer information, standard peer information based on a randomly drawn reference group, or targeted peer information whose reference group is drawn from lower earnings percentile ranks. The targeting rule is calibrated using es...
The project analyzes the role of information dissemination regarding new technologies and more efficient agricultural practices, and the potential bottlenecks extension services might face in their role of bridging the distance between the research institutions and the local farmers. We consider an ICRAF program targeting dairy producers in Uganda. The farmer trainer (FT) program focuses on dissemination of a set of practices to improve animal feeds and use them more efficiently. EADD trains volunteer farmer trainers, who in turn train other farmers in the production and use of the high-value animal feeds and feeding practices. This study is aimed at estimating the overall impact of EADD farmer Trainer approach, as well as analyzing the impact of different variations of the Farmer to ...
We study how much individuals are willing to pay for different news articles depending on group identities. We also examine the implications of news avoidance and news exposure on attitudes and beliefs.
In a previous survey we studies how much individuals are willing to pay for different news articles depending on group identities (https://doi.org/10.1257/rct.13097-1.1). We also examined the implications of news avoidance and news exposure on attitudes and beliefs. In this survey experiment, we focus on beliefs regarding the conflict and mechanisms found in the first experiment
This study characterizes MBA students' mental models of monetary incentives, meaning their subjective beliefs about how different compensation contracts affect employee behavior.
We are conducting a conduct a correspondence study to measure hiring discrimination against transgender job applicants for entry-level positions in the US labor market. We randomly assign gender identity and race to fictitious resumes. We measure discrimination against both transgender women and men as well as non-binary applicants relative to cisgender men and women, and we compare differences between White and Black applicants. We consider labor markets across the United States in order to examine heterogeneity in discrimination based on local political climates.
Background: Self-control, self-defence self-efficacy, and mental resilience are among the fundamental psychological determinants of performance and competitive endurance in combat sports. However, scientific evidence regarding structured, evidence-based psychological intervention programs for professional female wrestlers is limited. This study aimed to examine the effect of a structured psychological intervention program based on psychological skills training on the levels of self-control, self-defence self-efficacy, and mental resilience in professional female wrestlers. Method: The research was conducted using a randomized controlled pre-test–post-test experimental design. A total of 30 professional female wrestlers aged between 18 and 25 participated in the study. Participants were...
While much attention has been dedicated to the health and well-being of children under 5, the needs of older children have been historically overlooked. However, children between 5- and 14-years face health-related challenges higher than previously realized, during a period of life critical for physical, psychological, cognitive and social development. In Zambia, the context for this study, the prevalence of malaria is highest in children aged 5-17, with 40% of children testing positive in endemic areas; a study based in Lusaka, the capital also reported high levels of morbidity in primary school children, with 35% reporting febrile symptoms in the past two weeks, 66% reporting cough, 25% reporting diarrhea, and 32% having worms in their stool. Many of these problems are caused or compo...
The aim of this study is to examine how general practitioners make decisions when evaluating ambiguous clinical scenarios. In particular, the research focuses on how information provided by third-party sources may influence clinical judgment and decision-making. The study involves approximately 500 general practitioners in Italy and uses a controlled experimental design based on standardized clinical vignettes. Participants are presented with a series of clinical cases that vary in terms of contextual information and the presence of additional decision-support material. Clinical decisions are assessed through probabilistic judgments and behavioral choices, such as requests for further investigations or referrals. Overall, the study aims to better understand the factors that shape clinic...
This research project examines local ties and the electoral success of mayoral candidates in local elections. We employ a conjoint survey experiment on electoral candidate preferences among voting-age residents (18-75 years) in Germany. Fielded by a German survey institute, the survey aims to quantify voters’ relative preferences for mayoral candidate attributes, with a particular focus on locality markers in local elections. We conceptualize local identity as a multidimensional construct encompassing ascribed (birthplace), achieved (length of residence), and performative (local civic engagement) dimensions, which are experimentally varied in the conjoint design. The study examines how these dimensions shape perceptions of candidates as members of the local in-group and, more broadly, h...
