A field-experimental examination of differential treatment of Jewish Americans focusing on the K12 labor market.
This study examines package size changes. It has two empirical parts: first, we exploit supermarket scanner data by developing an algorithm to identify size changes, which allows us to provide novel descriptive statistics and study how consumer respond to size and price changes. Second, we conduct an online experiment to investigate whether consumers respond differently to these two types of changes and to test whether different ways of displaying information causally affect consumer decisions. We also examine how package size changes affect the welfare of different groups of consumers and discuss how our results relate to different public policies. The empirical analyses are guided and complemented by theoretical models.
The paper evaluates a new intervention seeking to address the problem of youth violence. Choose to Change (C2C) is a program that combines trauma focused cognitive behavioral therapy with wraparound services. This is the first time that these services are being offered together and rigorously evaluated. C2C will serve at least 570 at-risk youth during the years 2015-2019 in various neighborhoods of the South Side of Chicago, with a possibility for future cohorts. As there is little definitive evidence on the effectiveness of intensive services programs for high-risk youth, identifying programs that are successful with this population is a key policy priority for many cities across the country.
The online data industry has often heralded the benefits of online tracking and targeting, particularly in the context of online advertising. Its claims are juxtaposed by the privacy concerns associated with the vast number of ad-tech companies tracking and analyzing consumers’ online behavior – often without consumers’ awareness. We designed a field experiment to analyze the impact of online tracking, targeting, and advertising (as well as the impact of ad-blocking and anti-tracking tools), on a variety of consumers’ online behaviors (including browsing, digital news/information/entertainment consumption, online searches, interactions with LLMs, interactions with privacy settings and "consent mechanisms, online shopping, and so forth), as well as a variety of consumers' outcomes (inclu...
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. ...
