Transgender people experience worse labor market outcomes compared to similar cisgender peers; recently, research has found causal evidence of discrimination against this group in multiple settings. I propose a field experiment and a set of survey experiments involving fictitious A.I.-generated headshots, where the extent to which individuals “pass” as cisgender is experimentally manipulated, as is whether applicants indirectly discloses their transgender identity via a male-to-female name change. I aim to measure (1) discrimination against transgender women, (2) whether not "passing" as cisgender exacerbates discrimination (i.e., is there "passing privilege"), and (3) what mechanisms may be driving discrimination.
This study consists of three randomized controlled trials (RCTs) designed to improve our understanding of the interaction between a health crisis and political behavior in authoritarian countries. All three are conducted as part of a nationally representative telephone survey of about 1600 adult residents of Russia in April 2020, early in the COVID-19 outbreak. The first RCT investigates three mechanisms through which the coronavirus pandemic might be impacting support for Russia’s president and other leaders. The second RCT investigates how Russian President Putin’s public responses to the pandemic is shaping ordinary people’s behaviors that are widely believed able to influence the spread of the virus. The third RCT considers whether the same leader’s endorsement of health-promoting b...
This study evaluates the impact of providing information on longevity and financial literacy on individuals’ expectations and economic decisions. We conduct an incentivized online randomized controlled trial among approximately 3,600 UK residents aged 50–70, recruited via the Prolific platform, with data collection planned for April–May 2026. Participants are randomly assigned to receive: (i) information on age- and gender-specific survival probabilities, (ii) information on the returns and risks of financial investments, (iii) both types of information, or (iv) no information (control group). The study examines whether individuals update their beliefs and decisions in response to these interventions. The primary outcomes are (i) the gap between subjective survival probabilities and o...
We will conduct a lab experiment to evaluate interventions that leverage blockchain features to promote truth-telling. Specifically, we test how information transmission noise can promote truth-telling.
Traditional fired clay bricks dominate the construction sector in Bangladesh, contributing significantly to air pollution and topsoil degradation. Although cleaner, non-fired alternatives like concrete blocks exist, their adoption remains low. This study evaluates whether reducing information frictions and capacity constraints can accelerate adoption of blocks. We implement a three-arm cluster randomized controlled trial across 66 upazilas (sub-districts) in 22 districts (total baseline sample N = 3,056 respondents). Upazilas are randomized within district into: (i) Control (no intervention), (ii) Treatment 1 (T1): information workshop on block usage plus a block supplier directory targeted to contractors, procurement officers, and private clients, and (iii) Treatment 2 (T2): T1 plus ha...
Background: For thousands of years, khat chewing has been a common habit throughout the Horn of Africa and the Arabian Peninsula. Chewing fresh khat releases compound structurally related chemicals to amphetamines. It is estimated that more than 20 million people in Africa and the Arabian Peninsula are habitual khat chewers. Khat chewing leads to several health problems, including mood swings, hyperactivity, aggressiveness, anxiety, depression, high blood pressure, manic behavior, paranoia, Insomnia, poor concentration, and psychosis. Objective: This study aims to develop, validate, implement, and evaluate the effect of health education intervention program to improve attitude, knowledge, perception, and self-efficacy on khat chewing among secondary students in Mogadishu, Somalia. ...
I am running an RCT in 80 government and 40 low-cost private schools in Cape Coast Ghana for first grade students. These schools get one or both of two cross-randomized treatments. One treatment organizes scripted parent meetings where parents are 1) told the benefits of doing literacy activities with their child at home (e.g. asking what they learned in school, reading with them, going through school materials etc.), 2) trained on how to understand the report card they get on students literacy scores, and 3) briefly trained how to run a 1-minute reading assessment using provided materials on their child. The other cross-randomized treatment trains school leaders to better coach their teachers in teaching literacy, and also how to interact/engage parents. I am studying the interaction o...
This randomized controlled trial investigates how artificial intelligence (AI) assistance influences strategic decision-making in mergers and acquisitions (M&A). The study tests whether managers trained in the Theory-Based View (TBV) of strategy produce more outcome-aligned acquisition decisions and show a higher confidence in their assessments when aided by general-purpose or agentic AI systems. Three experimental arms are implemented with at least 400 experienced managers from the MedTech and Biotech industries: (1) Control – TBV training plus web search; (2) General AI – TBV training plus ChatGPT (GPT-5.4, reasoning effort set to medium); and (3) Agentic AI – TBV training plus ``Aristotle'', a multi-agent system developed at Bocconi University that applies TBV reasoning. Participa...
This study examines whether AI mental health services can reduce socioeconomic inequality in access to mental health support, relative to traditional human mental health services. Mental health services are often underutilized, particularly among individuals from lower socioeconomic backgrounds. Financial constraints, stigma, accessibility barriers, and concerns about judgment may disproportionately affect these groups. AI-based counseling tools may lower some of these barriers by offering lower cost, greater immediacy, and perceived anonymity. In an online experimental survey, participants are introduced to both AI-based and human-provided mental health services. We elicit their willingness to pay (WTP) using the Becker-DeGroot-Marschak (BDM) incentive-compatible mechanism and ra...
This study aims to examine the impact of integrating refugees into Ethiopia’s national digital identification document (ID) program ‘Fayda’, providing them with a form of government ID that is valid and widely recognised across the country. Globally, approximately 850 million people lack official IDs, with populations living in fragile and conflict-affected contexts disproportionately affected. This ‘identity gap’ perpetuates cycles of poverty and exclusion by limiting access to services and economic opportunities. In collaboration with the Government of Ethiopia, we implement a large-scale randomized controlled trial, in which randomly selected refugee households in three regions of the country receive early access to the national ID program. We will assess the causal impact of receivi...
