  • Changing Producers' Risk Attitudes
    Last registered on May 13, 2021

    We explore the prevalence of risk attitude reversals for experienced producers. Prior literature has identified a discrepancy in risk attitudes between comparing and pricing lotteries. Specifically, on average, individuals appear to be more risk-neutral when pricing lotteries and risk-averse when comparing lotteries. Our study elicits certainty equivalents and probability equivalent using choice lists--a pricing and a comparing task. To explore the generalizability of this discrepancy of risk attitudes across contexts, we study experts' behavior and choices with substantial incentives. 

  • Early Childhood Programs Change Test Scores but Do They Change Brain Activity?
    Last registered on May 13, 2021

    Early childhood programs impact test scores, but do they affect brain activity, and how do such neural changes impact future skills? To study these questions, we use a field experiment that randomized children to preschool or to a control group for one year. Following the intervention, we collect data on children’s neural activity during academic and executive functioning tasks using electroencephalography (EEG).

  • Can a job app help rural migrants who lost their jobs in the COVID lockdown re-integrate into urban labour markets?
    Last registered on May 13, 2021

    The study is motivated by the policy challenge of re-integrating recent graduates from a large scale training program in India (DDU-GKY) back into the labour market following the massive job losses caused by the Covid-19 pandemic. The DDU-GKY programme targets rural poor youth, and provides short-term training with guaranteed job placement. This study seeks to evaluate the effectiveness of an app-based job platform that matches job seekers with employers, using an encouragement design. The Jharkhand State Livelihood Promotion Society (JSLPS) has called 1,122 rural youth, randomly selected from 2,260 former DDU-GKY trainees from Bihar and Jharkhand, to inform them about the government-supported app Yuva Sampark and help them register. The main outcomes of this study are job search activi...

  • Interactive Phone Calls to Improve Reading Fluency
    Last registered on May 12, 2021

    We conduct an adaptive experiment to select one out of six treatment arms of biweekly phone calls to parents that deliver reading exercises for first graders. The experiment is carried out in two waves - start to midterm, and midterm to endterm - during term 3 of the first grade in a sample of 108 private primary schools in Kenya. The method uses Bayesian econometrics to estimate average treatment effects and exploration sampling (Kasy and Sautmann, 2021) to assign parents to treatment arms in each wave. The objective is to identify the treatment arm with the highest average "correct words per minute" (cwpm) score.

  • Gender Discrimination elicited in the general population of the United States.
    Last registered on May 12, 2021

    We study gender discrimination in hiring decisions in a representative sample from the United States. Participants are incentivized to choose between two candidates, one male, one female, to write an advertizing slogan for a product. They see information about the candidates, as well a sample of past work (a slogan for another product). Past work was either performed alone or in a team. Our first study will examine how discrimination varies between individual and teamwork settings, varying team composition, gender stereotypes attached to the products, and two policies aimed at reducing discrimination. Our second study will examine discrimination in the aggregate and how it varies with exposure to shocks during the ongoing COVID-19 pandemic.

  • A Cluster Randomized Controlled Trial of Blight Remediation and Community Outreach to Improve Residents’ Perceptions of Safety and Wellbeing in Buffalo, NY
    Last registered on May 11, 2021

    Blight and crime are detrimental to the physical, mental, and social health of individuals and communities. Blight (e.g. physical disorder, vacant structures) gives the impression of low levels of social cohesion and provides concealed spaces in which criminal activity has been shown to occur. There is growing evidence that place-based interventions may successful and sustainable in improving wellbeing by changing the structures of places that enable crime and blight to remain persistently high. This place-based intervention brings together public servants and community partners for intensive and rapid beautification and restoration, outreach and education, and codes and law enforcement focused on blocks in distressed neighborhoods. The program runs May-October, targeting clusters of 20...

  • Cognitive Noise in Belief Formation
    Last registered on May 11, 2021

    The study's objective is to test whether there is more cognitive noise in subjects' belief formation in an environment with more uncertainty.

  • Behavioral responses to credit repayment: the effect of messages and renegotiations offers
    Last registered on May 11, 2021

    This project aims to offer clues on the behavioral motives that affect financial decision-making by individuals. We evaluate the randomized administration of behaviorally motivated SMS messages and renegotiation options implemented by a financial institution. The treatments will include behaviorally motivated texts intended to nudge non-business clients into debt repayment. Thus, our trial will test out the effectiveness of behaviorally motivated messages, the relative effectiveness of different behavioral motives and the interaction of these two elements with renegotiation options. This way, through randomization and a period of monitoring and follow-up on clients, this project hopes to identify the most effective behavioral motives for financial nudges in relation to repayment outcome...

  • The public's opinions on the effect on COVID-19 vaccine intentions from information about people's extreme actions to get vaccinated
    Last registered on May 11, 2021

    In this study, participants will be asked to predict and explain the effects on COVID-19 vaccine intentions from two types of information about extreme behavior to secure access to the vaccine. More precisely, participants in treatment 1 will be asked to predict and explain the effect on vaccine intentions from information about some people taking extreme actions to jump the line for the vaccines, and participants in treatment 2 will be asked to predict and explain the effect on vaccine intentions from information about so called "vaccine hunters." (Participants' predictions will later be compared to the actual outcome, i.e., results from a previous study that documents the effects on vaccine intentions from the information about the extreme behavior described in treatment 1 and 2 in th...

  • Personal Experiences and Political Views among Nepalese Politicians
    Last registered on May 11, 2021

    We recruit local politicians in Nepal for a phone survey to test whether their personal experiences, and especially participation in the Nepal People’s War, affect their political views and policy priorities. First, participants are randomized into three groups: i) participants in the control group are not asked to reflect on the link between their personal experiences and policy priorities; ii) participants in the “personal experiences prime” treatment group are asked to reflect on how their personal experiences affect their policy priorities, without any specific mention of the civil war; and finally, iii) participants in the “civil war prime” treatment group are asked to reflect on their personal experiences during the civil war and how these affect their policy priorities. We then m...
