We aim to understand what drives individual overplacement when participants are asked questions about their ability or intelligence. Our main hypothesis is that overplacement is driven by a desire to not perceive oneself in the very bottom of the distribution (lowest quartile), rather than a desire to place oneself at the very top of the distribution (highest quartile). To test this hypothesis we will compare participants’ beliefs when asked to place themselves in two cases: below or above median (Median condition), and in one of four quartiles of the distribution (Q1-Q4, Quartiles condition). We also hypothesize that there will be a difference by gender, according to which men will display a stronger desire to avoid the bottom quartile than women. The study will consider two domains, a...
Mediation is widely used because it is faster, cheaper, and more flexible than courts. Yet a growing body of evidence suggests that the informality of mediation can disproportionately disadvantage less powerful parties, particularly those marginalized by gender, race, or ethnicity. In response, demand for more structured and rigorous mediation practices, combined with recent technological advances, has spurred the growth of Online Dispute Resolution (ODR) systems. In a standard ODR system, the mediator is an algorithm defined by predetermined rules. Although these protocols are designed to deliver impartial outcomes, we know little about how gender visibility shapes behavior and outcomes in algorithmic mediation. We study this question in a controlled experiment using the algorithmic me...
Accumulated evidence on present-biased preferences indicates that individuals at times exhibit a disproportionate preference for immediate rewards. Rationalizing theories of quasi-hyperbolic discounting implicate a behavioral parameter, β, capturing this preference. Our central question is whether individuals are aware of their own present bias. While prior work focuses on forward-looking awareness — asking if individuals appropriately forecast the effect of present bias on future behavior — this project will also consider backward-looking awareness — asking if individuals appropriately understand the impact of present bias on past behavior and incorporate it into their recollections and evaluations
This pre-registration outlines a randomized controlled trial testing whether stress constrains information acquisition among 1,200 low-income parents of kindergarteners in Mumbai. The experiment implements a 2x2 factorial design: parents receive either (i) a stress-relief breathing routine (with a tactile bracelet cue) or a bracelet-only control condition, and (ii) daily curiosity prompts that vary in signal precision---high-precision prompts elicit bounded, verifiable responses (e.g., counting, binary choices), while low-precision prompts require open-ended interpretation (e.g., ``why'' or ``how'' questions). This design isolates whether stress disproportionately impairs the processing of ambiguous signals. I pre-register four confirmatory hypotheses on emotional regulation, belief upd...
We use a randomized controlled trial to investigate the impact of a large call- and WhatsApp-driven intervention aimed at enhancing parental participation in their child’s education on foundational learning outcomes of children. The intervention consists of the following elements: a) telephonic assessment of the child using simple assessment tools, b) communicating result to the parents, c) sharing practice material over WhatsApp, and d) periodic calls to encourage parents to adopt specific practices to facilitate child’s learning. The baseline was conducted between November 2025 and January 2026. The endline will be conducted during August to September 2026. 5644 children spread across various locations in Delhi (India) were randomized in treatment and control groups. Children...
Repeated games with a long-lived player facing a sequence of short-lived players has, sins these games were first studied in Fudenberg and Levine (1989), been the focus of much theoretical work. In more recent years these models have received much attention due to their application to trade on online platforms such as Ebay and Amazon (which is becoming increasingly important). Like the more studied case of two long-lived players, the case with one long-lived player also suffers from multiplicity. Thus, while it is clear from a theoretical perspective that repeated interactions can help long-lived and short-lived players coordinate on mutually beneficial outcomes, it is unclear how this will come about. We set out to experimentally study strategy choices in repeated games with lon...
This impact evaluation aims to measure the causal impact of the ILO’s Get Ahead business training programme on the profitability, growth and survival of female-owned businesses in Kenya, and to evaluate whether any gains in profitability come at the expense of other business owners. To do so, the evaluation will use a randomized control trial (RCT) methodology with a two-level randomized experiment: randomized selection of villages, and of individuals within villages. The study works with 3,538 individuals in 157 markets. In addition to measuring the impact of this training program, individuals assigned to training are also then randomly assigned to one of three different invitation choice structures to measure the extent to which variations in the way in which people are invited to t...
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...
This study examines whether individuals’ responses to artificial intelligence depend on the identity dimension through which they interpret technological change. Motivated by a two-dimensional framework in which individuals can identify with an economic group or a cultural group, participants first report their expectations about the consequences of AI and are then randomly assigned to reflect on their economic identity, cultural identity, or a no identity baseline. We examine whether inducing identity along different dimensions changes AI-related opinions and donation allocations across organizations addressing different economic or cultural consequences.
This field experiment studies the supply side of the economics of public procurement by lowering the cost of finding and preparing a bid and observing what firms then do. Croatian firms that already bid for public contracts are surveyed and randomly assigned to three weeks of free access to an integrated procurement platform, or to a waitlist receiving identical access three months later. The platform is an artificial intelligence specialized for public procurement: it matches notices to the firm's profile, reads tender documentation and extracts the award criteria, assists in preparing submission documents, and adds work ow management and analytics. The waitlist arm receives nothing in the meantime, so the comparison is against the public register and whatever general-purpose artificia...
