  • Collective decisions and intertemporal risk choices
    Last registered on July 04, 2026

    Many critical real-world choices—ranging from corporate board investments to financial regulatory policies—are made by groups rather than isolated individuals. Crucially, these collective decisions are rarely simple; they routinely involve multi-dimensional settings where outcomes are both uncertain (risky) and delayed in time (intertemporal). While standard economic theories often assume a frictionless aggregation of preferences, real-world committees operate under specific formal protocols: institutional voting thresholds and asymmetric distributions of voting power.This study conducts a controlled laboratory experiment to systematically investigate how formal institutional designs shape collective choice in these complex environments. We implement a randomized 2 X 2 between-subject f...

  • Peer Networks and Educational Migration: Experimental Evidence from India
    Last registered on July 03, 2026

    This randomized controlled trial tests whether peer networks can encourage educational migration among prospective university students in India. I sample 2500 high school students (referred to as mentees) from secondary schools across Maharashtra and randomly connect half of the sample with current university students (referred to as mentors) who are educational migrants themselves. The intervention consists of semi-structured conversations conducted over the phone prior to college application deadlines. I measure impacts through surveys with students and parents: one midline survey before entrance exams, and another after college admissions conclude. Outcomes of interest include realized and hypothetical educational migration choices as well as beliefs about costs and benefits of educa...

  • Testing Identifying Assumptions in Examiner IV Designs: A Vignette Experiment with Polish Prosecutors
    Last registered on July 03, 2026

    Many empirical studies in economics, criminology, and public policy use the random assignment of cases to decision-makers—judges, prosecutors, bail magistrates, disability examiners, patent reviewers, and caseworkers—to identify the causal effects of their decisions. These “examiner IV” designs rely on a monotonicity assumption: examiners who are stricter on average must be weakly stricter for every individual case. Yet this assumption is essentially untestable in administrative data, because the same case is rarely decided by multiple examiners. This study conducts a vignette experiment with up to 250 Polish public prosecutors, each of whom independently recommends a sentence, including both type and severity, for the same fixed set of criminal cases. Observing many prosecutors’ dec...

  • Informed Merchants: A Randomized Field Experiment on Peer Data of SMEs
    Last registered on July 03, 2026

    Small and micro enterprises are the foundation of emerging market economies. Despite their aggregate importance, these firms often operate with limited market information. A small merchant may observe her own performance, but she rarely observes the performance of comparable nearby peers. This lack of peer information may prevent merchants from accurately assessing their market position and from making effective business decisions. This study uses a randomized field experiment to examine whether providing merchants with peer benchmark information affects their future decisions and performance. Eligible stores are randomly assigned to either a control group or an informational treatment group. Treated stores receive weekly in-app access to peer-information (revenue and relative standing)...

  • Decentralization with Guardrails: Enhancing the Zambia Constituency Development Fund
    Last registered on July 02, 2026

    This study examines the design and impact of decentralization reforms to Zambia’s Constituency Development Fund (CDF). The reforms give selected Local Authorities (LAs) greater decision-making power and procurement flexibility to improve the efficiency and responsiveness of local public goods provision.

  • Beyond Box-Ticking: Bureaucrat-Firm Relationships and Policy Success
    Last registered on July 02, 2026

    Many active labor market policies in low- and middle-income countries struggle to reduce youth unemployment (McKenzie 2017; Card et al. 2018). A growing literature suggests that the challenge may lie not only in policy design, but also in how policies are implemented by street-level bureaucrats (Besley et al. 2022; Bandiera et al. 2021). In this project, we focus on the performance of bureaucrats tasked with delivering these programs and the potential importance of misaligned incentives. Bureaucrats are frequently evaluated on easily observable, “box-ticking” outputs—such as the number of vacancies collected—rather than on harder-to-monitor outcomes like sustained job placements. This misalignment may skew effort toward the easily observable parts of the job. We study this question in A...

  • Profile pictures for experiment on religious hiring discrimination
    Last registered on July 02, 2026

    The goal of this experiment is to validate a set of AI-generated profile photographs that will later be used in a factorial survey experiment involving recruiters and HR professionals. The photographs are designed to represent young job candidates whose ethnic background is visually ambiguous, while allowing the addition of specific religious cues (e.g., headscarf, cross necklace, beard). The pre-test serves two main objectives. First, it verifies that the baseline photographs do not strongly signal a specific ethnic background. Second, it evaluates whether the selected photographs are comparable in terms of perceived physical attractiveness.

  • The effect of losing a competition: the role of gender, unfairness and feedback
    Last registered on July 02, 2026

    Women are underrepresented at every level of the corporate ladder. A growing and important experimental literature suggests that women are both more likely to avoid competition and drop out of competitive environments after experiencing disappointment than men. These laboratory measures seem also to predict career choices and, hence, partly explain the gender gap. We study the role of perceived unfairness in explaining gender differences in willingness to compete again in response to losing a competition. We ask whether men and women differ in how they respond to losing or winning a competition and whether these differences increase or decrease in presence of unfair conditions. Moreover, we aim to understand which women and men drive the gender gap. For this purpose, we run a post-exper...

  • Motivated Beliefs about Others' Preferences
    Last registered on July 02, 2026

    We study whether individuals form motivated beliefs about others' preferences when such beliefs can rationalise self-interested behaviour. In an online experiment, participants report their own willingness to work (WTW) on real-effort tasks and predict a counterpart's WTW. Participants are randomly assigned to a role (Employer or Worker) and an incentive condition (Low or High). Employers make a payoff-relevant decision about how many tasks to assign their counterpart, while Workers act as pure predictors with no such stake. We test whether Employers report higher beliefs about a counterpart's WTW than Workers, and whether stronger incentives to assign tasks widen this gap. Using higher-order beliefs, we further examine whether individuals anticipate motivated reasoning in others, and w...

  • Probabilistic Cash Rebates and Consumption Choices under Carbon Pricing
    Last registered on July 02, 2026

    This study uses an online experiment to examine how consumers respond to different types of cash rebates linked to environmentally relevant consumption choices. Participants make repeated decisions about how many units of a product to purchase under a fixed price that reflects a carbon charge, with lower consumption associated with greater environmental benefits. We compare behavior under several treatments inlcuding a no rebate control, a guaranteed cash rebate, and several probabilistic rebate schemes that differ in the likelihood of rebate payment. The study is designed to assess whether probabilistic rebates generate similar behavioral responses to guaranteed rebates, and to examine whether responses vary systematically with the probability of receiving a rebate. This experiment con...
