I investigate the impact of experimentation on performance in early-stage ventures, seeking to identify the venture-level and market-level conditions under which experimentation is most valuable. I propose a novel theoretical framework and test its implications via a field-based randomized controlled trial. The experimental work takes the form of an encouragement design.
We will utilize a robo-advising setup to investigate the impact of financial literacy on investors, specifically focusing on the concepts of beta and alpha. Partnering with a large brokerage firm, we will study the effects of educating investors about beta and alpha in mutual funds and stocks. To enhance investors’ understanding, we will integrate a back-end language model (ChatGPT/DeepSeek/Doubao/Kimi) system with the robo-advisor. We aim to determine whether learning about beta influences investors to prefer investing in ETFs or index funds rather than directly in active mutual funds or individual stocks. We will also examine whether a one-click automatic enrollment mechanism has a larger impact compared to a self-assembled portfolio, and if this gap is smaller for investors supported...
We study the causal effect of different narratives about long-term unemployment on beliefs and behaviors of unemployed job seekers from Denmark.
We will conduct an intervention to test whether performing a good action immediately after participating in an environmental information campaign influences the campaign’s effectiveness on recycling behavior. Specifically, we will offer a randomly selected sub-sample of participants the opportunity to make a contingent donation in the event of winning a monetary prize. Our analysis will assess whether being offered the chance to donate affects the campaign’s impact on waste separation.
This randomized field trial is a SMS voting reminder intervention in Finnish 2025 county and municipal elections.
We study two programs designed to enhance the numeracy skills of primary school-age children in Colombia. One program supported parents by providing them guidance using SMS and WhatsApp, while the other supported teacher by providing formal training on effective teaching strategies though an in-service professional development program. We compare their relative effectiveness and cost-effectiveness, and study potential complementarities or substitutability between the two programs by conducting a Randomized Controlled Trial, randomly assigning children to one of four groups: (1) parenting program only, (2) teacher training program only, (3) both programs, or (4) no program participation.
Policymakers often confront situations in which policy effectiveness hinges on appropriate strategic communications. We propose to employ a between-subject survey experiment conducted with depositors in the United States and Canada to test different messaging strategies in the context of a bank failure caused by a deposit run. The survey experiment will be conducted online between April and May 2025, with respondents randomly assigned to one of the four messaging conditions. We expect to find that in both countries, messages that convey policy certainty - commitments to effectively offer unlimited deposit insurance - will be most effective in halting the spread of the deposit run. We expect this finding to be especially pronounced in the United States given its long history of repeated ...
Will be made available upon project completion. Further details are in the Pre-Analysis Plan.
This study considers the following questions: Do people have a weaker understanding of the goals of monetary policy and how it works than they do of the goals of fiscal policy and how it works? Does understanding of the goals of monetary policy and how it works after viewing a video produced by the Federal Reserve Bank of St. Louis? Does viewing this video help close the gap between people’s understanding of monetary policy and their understanding of fiscal policy? To answer these questions, we conduct a lab experiment where subjects first take a 16-question baseline test, with 8 questions on monetary policy and 8 questions on fiscal policy. The subjects are then randomized into a treatment group and control group. The treatment group then watches a 10-minute video that was pr...
Front-line employees hold valuable insights that can enhance strategic decision-making and operational efficiency, yet their knowledge often fails to reach upper management. This project investigates whether supervisors and middle managers act as barriers to bottom-up knowledge sharing due to hierarchical structures, micromanagement, or lack of psychological safety. We conduct a randomized controlled trial in partnership with a large African bank where supervisors in randomly selected branches receive supportive leadership training. Using employee survey data collected at baseline and endline, we assess the impact of this intervention on knowledge sharing and broader organizational outcomes.
