In this episode, our guest Stefano DellaVigna shares his approach to answering research questions through various data sources, including lab experiments, natural experiments, and field experiments. We explore the significance of seeking out natural experiments and their value in enhancing our understanding of human behavior. Using examples such as the impact of violent movies on violence and changes in Fox News subscriptions, Stefano reveals surprising findings and their implications. We also discuss the availability of experimental data and the establishment of nudging units for research purposes.   Stefano DellaVigna is the Daniel Koshland, Sr., Distinguished Professor of Economics, Professor of Business Administration at the University of California, Berkeley, and co-director of the Berkeley Initiative for Behavioral Economics and Finance. His research interests are, among others, in the area of behavioral economics, applied microeconomics and media economics.   You can find his paper on the influence of movie violence on violent crime here and his paper on the “Fox News effect” here.

In this episode Tommaso Bondi shares his research on cultural markets with us. We take a deep dive into the insights he gained when studying online reviews and he explains to us why, counterintuitively, earning public recognition does not necessarily lead to higher ratings. A finding which, as we learn from Tommaso, is closely related to how well customer preferences and product match. Tommaso’s result does not only have theoretical merit but also seems to be observable in practice. We then also discuss the impact of experts on reviews and finally take a short detour to strategies of brick-and-mortar bookstores.   Tommaso Bondi is Assistant Professor of Marketing and the Demir Sabanci Faculty Fellow of Marketing and Management at Cornell Tech and the SC Johnson Graduate School of Management at Cornell University. His research is mainly focused on economics of digitization, quantitative marketing, and behavioral and experimental economics. You can find his papers “Alone, Together: A Model of Social (Mis)Learning from Consumer Reviews” and “The Good, The Bad and The Picky: Reference Dependence and the Reversal of Product Ratings” here and here.

In today’s episode, we explore one of the classics in Bargaining theory: The Rubinstein Bargaining Model. And we have found the perfect guest - who better to explain this bargaining model than its founder Ariel Rubinstein himself! Ariel not only shares how the idea of the model came to be, but he also comments on some results and critically discusses whether the Rubinstein Bargaining Model (and Game Theory in general) has predictive or normative power for real-life situations.   Ariel Rubinstein is Professor of Economics at the School of Economics at Tel Aviv University and the Department of Economics at New York University. His research is focused on Economic Theory, in particular Decision Theory and Game Theory. You can download his books for free (also the book “Economic fables” mentioned in our episode) and check out his Atlas of Cafés on his website https://arielrubinstein.tau.ac.il/ . There, you also find his original paper introducing what came to be know the “Rubinstein Bargaining Model”: “Perfect Equilibrium in a Bargaining Model”

Monetary incentives are a part of our daily lives, from work bonuses to fines for minor traffic violations. But can they lead us to make bad decisions? In this episode, our guest Sandro Ambühl presents an empirical study in which he investigates this very question. He explains what constitutes a bad decision in the economic/rational sense and how people's decisions are related to regret, information, and the size of the monetary incentive.  Sandro Ambühl is Assistant Professor of Behavioural Economics of Financial Markets at the University of Zurich, where his research is focused on Behavioural Experimental Economics, Behavioural and Experimental Finance, Repugnant Transactions and Rational Inattention. You can find his paper “Can Incentives Cause Harm? Tests of Undue Inducement” here.

In this episode, we explore how time pressure and regret can influence our search behavior as customers in the world of online shopping. Our guest, Timm Opitz, sheds light on his research paper titled "Time Pressure and Regret in Sequential Search", which investigates the impact of urgency and regret on optimal search behavior by conducting experiments in a controlled environment. He also shares some strategies we can use to overcome the influence of urgency and regret in our shopping behaviour. Timm Opitz is economist currently pursuing his PhD at the Max-Planck-Institute for Innovation and Competition in Munich, Germany, where he is part of the Innovation and Entrepreneurship Research group. As such, his research interests are Entrepreneurship, Behavioral Market Design and Developmental Psychology. You can find his paper on "Time Pressure and Regret in Sequential Search" here.
