In this episode, we talk with Chris Roth from the University of Cologne about his paper “Designing Information Provision Experiments”. In this paper, Chris and his co-authors review the literature on information provision experiments and derive best practices for designing such experiments. We also discuss determinants of research productivity.

In this episode, we talk with Lise Vesterlund about her book “The No Club: Putting a Stop to Women’s Dead-End Work”, co-authored with Linda Babcock, Brenda Peyser, and Laurie Weingart. The book discusses how women are disproportionately assigned non-promotable tasks in the workplace and offers strategies for resisting these burdens to achieve more equitable professional advancement. Our interview focuses on why there is a gender difference in saying no in the workplace, as well as the process of publishing the book. 

In this episode, we talk with Matt Lowe about his randomised controlled trial, “Do virtue signals signal virtue?”, co-authored with Deivis Angeli. The research examines whether tweets about racial justice predict real-life actions, finding that while people who tweet about racial justice are generally more likely to act in line with those values, the sincerity of these signals diminishes when social pressure to speak out is higher. Our interview focuses on his findings, as well as his experience running a large experiment that involved over 200 research assistants to sample more than 11,000 academics.

In this episode, we talk with Ran Spiegler about his book “The Curious Culture of Economic Theory”. The book is a collection of essays about how the professional culture of economics shapes the way theory is done. Our interview focuses on Chapter 8, in which Ran describes the story behind his American Economic Review paper “Search Design and Broad Matching” co-authored with Kfir Eliaz. In this project, Ran and Kfir attempted to study a problem using an established but “unfashionable” modeling approach. Despite getting interesting results, they later rewrote the paper using the standard approach in the literature. Among other things, we discuss why they felt they had to do this and how the new design nudged them into asking certain questions they were originally not interested in.

In this episode, we talk with Simeon Schudy about his working paper “The Effect of Incentives in Non-Routine Analytical Team Tasks”, co-authored with Florian Englmaier, Stefan Grimm, Dominik Grothe and David Schindler (forthcoming in the Journal of Political Economy). Using a novel experimental setup, escape rooms, this paper investigates the effect of incentives on performance in non-routine analytical team tasks. The paper studies the value of incentives for both intrinsically and less intrinsically motivated teams. Further, it evaluates how incentives affect team organization and studies the impact of exogenously varying the demand for leadership in such tasks.

The following reference was also mentioned during the conversation:

In this episode, we talk with Marta Serra-Garcia about her American Economic Review paper “Enabling or Limiting Cognitive Flexibility? Evidence of Demand for Moral Commitment,” co-authored with Silvia Saccardo. This paper investigates the nature and flexibility of self-serving beliefs in decision environments where morals and personal incentives are in conflict. Through laboratory experiments, the authors distinguish participants who are willing to curb opportunities for self-serving beliefs, favouring moral behaviour, from those who seek the cognitive flexibility to entertain beliefs that can justify their selfish decisions.

In this episode, we talk with Johannes Haushofer about his paper “The Comparative Impact of Cash Transfers and a Psychotherapy Program on Psychological and Economic Well-being” co-authored with Robert Mudida and Jeremy Shapiro. This paper explores the possible interactive or synergetic effects between cash transfers and a psychotherapy intervention in Kenya. We discuss the surprising results of this study, some of the biggest challenges and ethical considerations such as the collection of sensitive data and randomisation of cash transfers itself.

In this episode, we talk with Ben Golub about his paper “Signaling, Shame, and Silence in Social Learning” co-authored with Arun Chandrasekhar and He Yang. This paper studies how signaling and shame-related concerns can reduce social learning. Throughout the conversation, Ben also shares helpful pieces of advice for young researchers ranging from working on multiple projects to writing better.

In this episode, we talk with Shengwu Li about his paper “Obviously Strategy-Proof Mechanisms”. In this paper, Shengwu introduces the notion of an “obviously dominant strategy,” which describes a strategy that is not only dominant but can also be recognised as weakly dominant by an agent with cognitive limitations.

In this episode, we talk with Peter Schwardmann and Egon Tripodi about their paper “Self-Persuasion: Evidence from Field Experiments at International Debating Competitions”. In this paper co-authored with Joël van der Weele, Peter and Egon study if people are more likely to believe in the veracity of a claim if it is convenient for them to do so.

In this episode, we talk to Pietro Biroli from the University of Bologna about his paper “Moral Hazard Heterogeneity: Genes and Health Insurance Influence Smoking after a Health Shock”. In this paper, Pietro and his co-author Laura Zwyssig show that individual behaviour is influenced not only by environmental constraints but also by genetic makeup, which carries implications for the fairness and effectiveness of health policies.

In this episode, we talk to Katy Milkman from the Wharton School of the University of Pennsylvania about some of the research that led to the production of her recent book, How to Change. Throughout this conversation, Katy shares with us what she has learned from her many years of experience as a behavioural science researcher and where she might go next to tackle the challenge that preoccupies her the most: changing behaviour for good.

In this episode, we talk to Daniel Gottlieb from the London School of Economics and Political Science about his paper “Lapse-Based Insurance”. In this paper, Daniel studies why customers lapse on their life insurance payments and how this is related to insurance pricing by combining a theoretical model with a survey data.

In this episode, we talk to Aurélien Baillon from Erasmus University Rotterdam about his papers “Bayesian Markets to Elicit Private Information”  and “Simple Bets to Elicit Private Signals”. In this work, Aurélien studies how we can elicit private information about questions for which we cannot verify if the subject responds truthfully, such as her subjective belief about whether she liked a product.

In this episode, we have a power couple joining us. We talk with Aislinn Bohren from the University of Pennsylvania and Alex Imas from the Chicago Booth School of Business about their joint paper “The Dynamics of Discrimination: Theory and Evidence”, co-authored with Michael Rosenberg. They conduct a natural field experiment to identify the dynamics of discrimination and its underlying source. The authors post content on a large online platform and exogenously vary the gender and evaluation histories of the associated accounts. When no evaluation history is available, questions posted to female accounts earn less reputation than questions posted to male accounts. However, the direction of discrimination reverses as more reputation is built. When content is posted to advanced accounts, women’s posts are favoured over men’s. Tune in for a discussion centered around the idea, the design, and the logistical implementation of the paper that has won the 2020 Exeter prize.

In this episode, which forms part of a series on ethics in behavioural science research, we talk with Sandro Ambuehl from the University of Zürich about his paper “An Offer You Can’t Refuse? Incentives Change How We Inform Ourselves and What We Believe”. To investigate how economic incentives may skew information gathering and beliefs about what a transaction entails, thus affecting the quality of decisions taken by subjects, he presents a model of costly information acquisition in conjunction with behavioural experiments, one of which includes the ingestion of insects in exchange for money. Tune in for a discussion centred around the project’s design, its ethical and logistical considerations, and on the ethics of incentivising subjects in economic experiments more generally.

In this episode, we talk to Josh Tasoff from the Claremont Graduate University. We discuss two of his papers that study if awareness raising interventions can cause people to consume less meat.

In this episode, we are joined by Michel Maréchal from the University of Zurich to discuss his 2019 Science paper “Civic Honesty Around the Globe” co-authored with Alain Cohn, David Tannenbaum and Christian Lukas Zünd. More than seventeen thousand wallets were handed in to reception staff at various institutions in major cities across 40 countries, whereby civic honesty was elicited by the rate at which these employees attempted to contact the owner. Neither the economists nor the non-economists were able to predict what happened next. The presumed relationship between honesty and self-interest is pitted against evidence of altruistic tendencies and individuals’ self-image concerns. Tune in for a discussion of the project’s origins, logistics, design choices, publication and media controversy.

In this episode, we talk to Dmitry Taubinsky from the University of California Berkeley about his paper “Regressive Sin Taxes, with an Application to the Optimal Soda Tax,” which he co-authored with Hunt Allcott and Benjamin B. Lockwood. This paper develops a theoretical model of an optimal “sin tax” i.e., a tax on goods that are considered harmful to consume. The theoretical framework is then applied to estimate the optimal soda tax.

In this episode, we talk to Johannes Abeler from the University of Oxford and Daniele Nosenzo from Aarhus University (formerly, the University of Nottingham) about their paper “Preferences for Truth-telling,” which they co-authored with Collin Raymond. The authors first conduct a meta-analysis with data amalgamated from more than 90 studies across 47 countries and 44,000 participants. They then test the set of existing theories that seek to rationalise truth-telling behaviours by iteratively eliminating models that cannot explain the stylised facts yielded by their meta-analysis. The surviving set of models is further refined by their own experimental evidence. The authors have provided transparent and intuitive data visualisations of their main meta-analysis findings on the accompanying website.

In this episode, we talk to Anna Dreber from the Stockholm School of Economics about her work on replication markets. In this project, Anna and her co-authors examine if markets can be used to predict whether scientific studies will replicate.

In this episode, we talk with Noam Yuchtman from the London School of Economics about his paper “Medieval Universities, Legal Institutions, and the Commercial Revolution,” which he published in 2014 with Davide Cantoni. Using data from medieval Germany, this paper examines the causal link between the emergence of universities, including the legal training they provided, and Europe’s Commercial Revolution.
