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 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 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.
In this episode, we talk with Roberto Weber from the University of Zurich about his paper “Identifying social norms using coordination games: why does dictator game sharing vary?,” which he published in 2013 with Erin Krupka. In this paper, Roberto and Erin introduce a new procedure for eliciting social norms, which they use to understand giving behaviour in one of the most studied experimental games, the dictator game.
In this episode, we talk with Bertil Tungodden from the Norwegian School of Economics about his project entitled “Fairness across the world” in which he and his collaborators elicited the fairness preferences of 65,000 individuals from 60 different countries. As of the recording of this episode, no paper from the project is available yet. However, the results of a pilot study comparing just Norway and the US were published as a separate paper: Cutthroat Capitalism versus Cuddly Socialism: Are Americans More Meritocratic and Efficiency-Seeking than Scandinavians?
In this episode, we talk with Leonardo Bursztyn from the University of Chicago about his paper “Misperceived Social Norms: Female Labor Force Participation in Saudi Arabia,” which he co-authored with Alessandra L. Gonzalez and David Yanagizawa-Drott. In this paper, the authors examine whether one driver of low female labour force participation in Saudi Arabia is that male guardians incorrectly believe that other men disapprove of female labour force participation.
In this episode, we talk with Heather Schofield from the University of Pennsylvania about her paper “Sleepless in Chennai: The Economic and Health Effects of Reducing Sleep Deprivation Among the Urban Poor”. In this paper, Heather and her co-authors Pedro Bessone, Gautam Rao, Frank Schilbach and Mattie Toma examine the impact of interventions that aim to improve sleep quality on the productivity of low income workers from Chennai, India.
In this episode, we talk with Noam Yuchtman from the London School of Economics about his paper “Protests as strategic games: experimental evidence from Hong Kong’s antiauthoritarian movement”. In this paper, Noam and his co-authors Davide Cantoni, David Y Yang and Y Jane Zhang examine how protesters in Hong Kong respond to information about the participation of other protesters.
