  • In AI We Trust? Understanding Human Trust in the Age of AI
    Last registered on February 10, 2025

    Intelligent machines, artificial intelligence (AI), and algorithms are reshaping our society in domains like hospitality, healthcare, and space exploration. As AI progresses, understanding human trust in AI and how it differs from scientific trust more generally, as well as the mechanisms shaping (mis)trust, is crucial for preserving the quality of the social fabric in a free society. Using a survey experiment as part of a nationally-representative panel study in the United States, this project compares how news of AI progress in linguistics, medicine, and dating, versus scientific advancements in the same domains, impact trust across diverse societal groups. For example, an AI breakthrough in linguistics might be perceived differently than a non-AI scientific discovery in the same ...

  • Validating measurement approaches for sensitive topics with administrative tax data in Uganda
    Last registered on February 09, 2025

    Our study will conduct a number of survey experiments to investigate the accuracy of different approaches widely used to estimate the prevalence of sensitive behavior in the social sciences.The context of the study is tax compliance in a sample of small- to mid-sized enterprises in Kampala, Uganda. By combining survey data with administrative tax records for the same firms, we assess the performance of different measurement approaches, benchmarked against the administrative data, within the same survey. This allows us to quantify measurement error in different self-reported measures of tax compliance and make recommendations for policy and research based on our findings. Based on the findings of the first survey data collection, we are running a second survey round to replicate the f...

  • College Success and Personalized Feedback
    Last registered on February 09, 2025

    This study is designed to create and administer a survey that identifies key areas of struggle for students, including financial stress, academic success, social life, and study habits. Based on the survey results, we will generate personalized emails for treated participant, providing targeted advice and resources to address their primary area of concern. The objective is to evaluate the effectiveness of these personalized interventions by examining their impact on various student outcomes, such as academic scores and personal perceptions of their struggles.

  • Understanding the Barriers to Paternity Leave Taking: Evidence from Japan
    Last registered on February 09, 2025

    Japan has one of the most generous parental leave policies for working parents, yet male employees remain reluctant to take leave. In 2021, only 14% of eligible Japanese fathers took at least one day of paternity leave, and conditional on taking leave, most men take less than two weeks of leave. Men’s reluctance to take paternity leave in Japan has been attributed to several factors such as the prevalence of traditional gender norms that are at odds with men taking on a caregiving role, career concerns surrounding the violation of ideal worker norms, and organizational climate and support for leave-taking. Recent work suggests that even as social norms change, individuals may actively enforce a perceived norm, even if they privately reject the norm because they incorrectly believe that ...

  • The effects of solicitation framing on donations
    Last registered on February 09, 2025

    Our goal is to examine the effect of different donation solicitation framings on the propensity to donate and donation amounts. In addition, we intend to examine the interaction between solicitation framing and donation matching. Finally, we are interested in examining the association between individual personality traits, solicitation framing and donation amounts. We intend to test the following research questions: 1) Does donor-oriented solicitation frame lead to more donations than charity-oriented and recipient-oriented frame? 2) Is donation matching less effective for donor-oriented frame? 3) Does solicitation frame which is aligned with donor’s personality traits lead to more donations?

  • Optimizing Cash Transfers with Social Empowerment Interventions to Reduce Child Marriage in Bangladesh
    Last registered on February 08, 2025

    Despite legal restrictions, child marriage remains prevalent in Bangladesh and in fact have gone up from 31% to 42% between 2020 and 2023. BRAC's Social Empowerment and Legal Protection (SELP) program is implementing an intervention that combines life-skills training and networking called "Shwapno Sharothi" (SS), and layering a conditional cash transfer component. This study employs a two-stage cluster Randomized Controlled Trial (RCT) to evaluate the impact of the empowerment (i.e. SS) and the marginal impacts of providing monthly conditoinal cash transfers of two different values. The RCT operates across 5 districts in Bangladesh, targeting 450 clusters (primarily a village) with a total sample size of 11,250 adolescent girls aged 13–17. Clusters are randomly assigned to four groups: ...

  • Testing Variations in the Two-Step Norm-Elicitation Procedure
    Last registered on February 08, 2025

    The experiment ‘Elicitation of Normative Expectations (ENE)’ examines the extent to which variations in the two-step elicitation method (e.g., Bicchieri & Xiao, 2009; Bicchieri et al. 2019; Görges & Nosenzo 2020) influence personal normative beliefs and normative expectations, i.e. the extent to which the elicitation method is robust to variations. To this end, each participant is asked about their personal normative beliefs and normative expectations regarding fairness in a dictator game. Three main characteristics are varied in eight different treatments: i) order of elicitation (before/after the task), ii) incentivization of normative expectations (yes/no), and iii) question on behavioural options (about fair share only/ about fair and selfish share). In addition, subjects participat...

  • The Impacts of Employee Excellence Rewards on Workers and Firms: The Role of Managerial Discretion vs. Worker Empowerment
    Last registered on February 07, 2025

    In this project, we will investigate the impact of workplace excellence rewards on workers’ productivity, attendance, earnings, and firm culture. It would be conducted in rural Uttar Pradesh, India in partnership with a large carpet producing firm, in 150 small firms that the partner firm sources from. The intervention will randomize whether and how bonuses for workplace excellence worth about 10% of the average worker wage are allocated. We would randomize, at the firm-level, whether bonuses for carpet workers are allocated (a) based on managerial discretion or (b) worker voting. We will use data on productivity, attendance, earnings, and perceptions about firm culture to understand whether and how different systems of rewarding workers can improve outcomes for workers and firms.

  • Skills Mismatch: Sources and Consequences
    Last registered on February 07, 2025

    Skills mismatch, defined by the discrepancy between workers’ skills and job skill requirements, can have negative effects on workers’ income and career progression. Past research has studied its causes separately which include (i) workers not having complete information about their own skill levels and labour markets, and (ii) lacking confidence or adherence to social norms. For example, female workers may perceive that a programmer is not a suitable job for women. The project will study the role of these factors and their interactions on skills mismatch using a randomised controlled trial (RCT). The RCT involves giving participants who are final-year college students in Thailand different treatments. The two main treatments are as follows: providing information on individual abilit...

  • Belief Elicitation under Ambiguity
    Last registered on February 07, 2025

    Beliefs play a critical role in many economic, political, and life decisions. Hence, researchers have been interested in eliciting individuals' beliefs to better understand their decision-making processes. A fundamental challenge in experimental economics has been creating incentives for experimental participants to truthfully report their beliefs. In recent years, researchers have developed sophisticated methods to elicit the beliefs of experimental participants in an incentive-compatible manner (see Schotter and Trevino, 2014; Schlag et al., 2015; Trautmann and van de Kuilen, 2015; Charness et al., 2021, for reviews). One state-of-the-art method to elicit beliefs is the binarized scoring rule (BSR), which is incentive compatible even under non-neutral risk preferences (Hossain and Oku...
