Game Changer - the game theory podcast

In this episode, we explore the challenges of multi-party negotiations and why reaching agreement becomes exponentially harder as more stakeholders enter the room. Our guest Lawrence Susskind explains the principles of the Mutual Gains Approach and we discuss applications ranging from local disputes over renewable energy projects to the intricacies of building data centres and setting up other lar...

In this episode, we explore what it really means to make a "good" prediction. Starting with something as ordinary as a weather forecast, we discuss why forecasting poses deep economic and game theoretic questions. Together with our guest Rakesh Vohra, we unpack the concept of calibration, examine how forecasts can be evaluated, and revisit the surprising insight that even someone without meteorolo...

In this episode, we explore how digital platforms transformed markets by dramatically reducing search costs and information asymmetries. Together with Sarah Auster, we dive into the "digital paradox" of endless choice, the unintended consequences of frictionless search, and what this means for the future design of platforms like Netflix and Amazon. Along the way, we uncover the broader economic st...

In this episode, we discuss zero-sum games and zero-sum thinking with our guest, Nageeb Ali. We begin by looking at the broader picture of how zero-sum thinking has become increasingly prominent in today's public debate and how it relates to Akerlof's classic "lemons" problem. Drawing on ideas from economics and game theory, Nageeb shares research connecting zero-sum thinking to questions in polit...

In this episode, we speak with Thilo Klein about daycare allocation in Germany – a problem that is still mostly run by uncoordinated offers, even though it is well understood in matching theory. The gap isn't theory; it's the missing layer that turns academic mechanisms into systems municipalities can actually run. Thilo Klein traces how that layer is now being built – through years of research, a...

In this episode, we speak with Rosemarie Nagel about the Beauty Contest, a classic game in economics. She introduces the setup, its origins, and the early research behind it. We then take a deeper look at the key insights from the Beauty Contest, in particular the concept of level-k reasoning and what it reveals about strategic thinking. Furthermore, Rosemarie shares how findings from these experi...

Europe's energy crisis has exposed deep structural flaws in how electricity markets work. But according to economist Natalia Fabra, much of the current debate is focused on the wrong problem. In this episode, we unpack why high prices are not simply a result of market design choices like uniform pricing – and why the real issue runs deeper. From the role of gas in price formation to the fundamenta...

In this episode, we explore how game theory and economics can inform the use of AI. Our guest, Annie Liang, introduces the concept of AI clones, systems designed to imitate specific humans, and discusses their potential applications, for example in recruiting. We examine the trade-off between the efficiency gains the clones can provide and the costs that arise when AI cannot perfectly create such...

Can we trust lab experiments to predict real-world behaviour? In this episode, we explore the question of external validity together with Jan Stoop. From classic dictator games in the lab to misdelivered envelopes with real cash in private homes, we discuss whether people act differently when they are being observed - and what happens when established lab findings meet reality. We also talk about...

What happens when an AI system faithfully follows a flawed goal? In this episode, we explore how even well-designed algorithms can produce dangerous outcomes — from amplifying hate speech to mismanaging infrastructure — simply by optimising a reward function which, like all reward functions, fails to encode all that matters. We discuss the hidden risks of reinforcement learning, why over-optimisat...

In this episode, we discuss how game theory sheds light on modern electoral competition. Our guest, Adam Meirowitz, introduces the classical model of candidate convergence and explains why real elections often depart from this prediction. We then explore the role of echo chambers and selective exposure, and why these surprisingly do not necessarily lead to greater polarisation. We also touch on ho...

Talk is cheap – literally. But if words cost nothing, why do we ever trust them? In this episode, Yale Professor Navin Kartik breaks down the game theory of communication. We kick things off with the basics: what is the academic definition of "cheap talk", and why does cheap talk sometimes work but other times break down? From there, we transition to Navin's own research, which explores deeper fac...

In this episode, we explore the foundations and evolution of decision theory. Our guest, Itzhak Gilboa, begins with a brief historical overview of how the field has developed over time. We naturally discuss maximising expected utility, Bayesian decision theory, and Savage's representation theorem. Itzhak then delves into critiques of the Bayesian approach, especially concerning its interpretation...

In this episode, we explore how game theory and network effects intersect to inform optimal incentive structures in organizations. Pau Milán walks us through his recent research,   co-authored with Nicolás Oviedo-Davila and Marc Claveria, which uses a novel game-theoretic model to show how the productivity of one employee can amplify the output of others in their network—and how firms can leverage...

In this episode we explore the most classical topic from Game Theory – equilibrium analysis. Our guest Colin Camerer shares insights on the game LUPI ('lowest unique positive integer'). We first discuss the actual mathematical equilibrium analysis and then dive into real life: results from a Swedish game show in which the game was played in a lottery format. Colin also compares the results from th...

In this episode we explore the economic and strategic foundations of networks – from personal connections in the labor market to complex webs of international trade and conflict together with our guest Matthew Jackson. He unpacks how networks shape opportunities, inequalities, and global dynamics, and how game theory helps us understand the power and fragility of these structures. Along the way, w...

In this episode we are talking about corporate scandals, selfishness, and how game theory can help us understand when people give in to temptation.   Carlos   Alós-Ferrer   explains how his "Big Robber" experiment shows that while people often act pro-socially in classical economic games, things change when individuals are given the chance to earn large sums of money at the expense of harming many...

In this episode, we dive into the world of experimental research on unstructured bargaining ,  exploring how real-world negotiations unfold when stripped of rigid rules and scripts. Our guest Emin explains how opening offers shape the conversation, the unspoken dance of reputation, and the ticking clock of deadlines – showing that even in seemingly messy contexts, strategic patterns emerge.   Emin...

In this episode we explore what motivates people to give, using insights from a Dutch TV game show where a live audience decides how to split €10,000 among three contestants. We discuss how real-world data from natural experiments can help answer questions about fairness, impact, and generosity - and what this means for fundraisers and policymakers.   Dennie van Dolder is Senior Lecturer (Associat...

In this episode we dive deep into the economics of digital markets with Dirk Bergemann. We discuss how search platforms like Google created entirely new marketplaces around user attention and private information, what makes digital markets so unique, and how auction design evolved to match the scale and complexity of internet advertising. Dirk also shares insights from his own research on how plat...

In this episode, we talk to David Pinsof about the surprising ways people form their beliefs and build alliances . Drawing on his survey with Cards Against Humanity, he shares how people often hold contradictory views and what this reveals about group coordination. We also dive into his game-theoretic model of coalition-building, explore how humor functions as a coordination tool, and discuss the...

In this episode we are talking to Vitali Gretschko about how generative AI can be used to simulate strategic behaviour in auctions. We explore where AI tools can support auction design, where they fall short, and how practitioners should interpret simulation results. Vitali also explains why AI is best seen as a co-intelligence that needs expert guidance.   Vitali Gretschko  is Professor for susta...

In this episode, our guest Rory Smead shares insights on spite and what game theory can teach us about this puzzling behaviour. He explains why people sometimes punish others even at a cost to themselves, and whether this can be understood through more than just fairness. Using the ultimatum game as a central example, he discusses how spite can influence decision-making and what this reveals about...

In this episode we are talking to Timo Vogelsang about why incentives aimed at reducing absenteeism can sometimes have the opposite effect. Based on a Field Experiment in a German supermarket chain, he explains why offering bonuses for attendance backfired. We also explore how incentives can unintentionally shape beliefs and undermine motivation.   Timo Vogelsang is Associate Professor of Manageri...

In this episode, we sit down with Philipp Strack to explore the hidden consequences of overconfidence. From distorted learning to discrimination and systemic bias, Philipp explains to us how overestimating ourselves can quietly shape our decisions, relationships, and even society — and why it's not always a bad thing.   Philipp Strack is a professor of Economics at Yale University with a secondary...
