The marriage penalty – how the church rewired cooperation networks | with Jonathan Schulz

In this episode we explore how historical kinship structures, shaped in part by decisions of the Catholic Church, may have fundamentally changed the way humans are able to cooperate on a large scale. Using game theoretic concepts like reciprocity and network structure, we uncover how bans on cousin marriages and even modern Facebook data can help explain patterns of trust and cooperation today.   Jonathan Schulz is Assistant Professor in the Department of Economics at George Mason University and Co-Principal Investigator of the interdisciplinary Historical Psychology Project. His research focuses on the historical and psychological roots of economic development, with a particular interest in how social networks and kinship structures influence cooperation.

In this episode together with our guest Klaus M. Schmidt, we explore the economic challenges behind global climate agreements. We discuss why past agreements like the Kyoto Protocol and the Paris Agreement struggled to deliver the desired results and examine how a new negotiation design centered on a uniform CO₂ price could lead to better outcomes. Klaus also shares insights from experimental studies testing this approach in practice.   Klaus M. Schmidt is an economics professor at Ludwig Maximilian University of Munich, and an expert in social preferences and contract theory, among others.  

In this episode, we explore how globalization has shaped trade and innovation—and why rising protectionism is challenging its benefits. What happens when countries impose tariffs and trade restrictions? And how can policymakers navigate the balance between open markets and domestic interests?   Claudia Steinwender is a Professor of Economics at Ludwig Maximilian University of Munich. Her research focuses on international trade, innovation, and economic history, with a particular emphasis on how globalization shapes firm behavior and trade dynamics.  

In this episode we are speaking with Sarah Mathew about cooperation – especially how cooperation is achieved in the absence of institutions. Sarah gives some theoretical background, shares the concept of free rider problems and the relationship to punishment. She then illustrates the background based on her fieldwork: She has studied how the Turkana people achieve cooperation when going on raids with possibly even deadly consequences for individual warriors.   Sarah Mathew is Associate Professor at the School of Human Evolution and Social Change at Arizona State University. Her research is focused on studying why humans cooperate and how the evolution of this unique form of cooperation is tied to the origins of moral sentiments, cultural norms, and warfare. To address these issues, she combines formal modelling of the evolution of cooperation with fieldwork.

In this episode we are speaking with philosopher Daniel Williams about misinformation—what it is, how it spreads, and whether it is truly on the rise in the form of “fake news”. We also explore why people cling to irrational beliefs and how rationalization shapes public discourse. Finally, Daniel shares strategies for tackling misinformation and engaging with those who hold questionable beliefs.   Daniel Williams is a philosopher and researcher at the University of Sussex. His research is focused on the social functions and causes of beliefs with a special interest in self-deception, religious beliefs, political ideologies, and delusions. In his blog conspicuous cognition https://www.conspicuouscognition.com/ Dan publishes interesting essays on various topics.  

In our 100th episode, we bring together Matthias Schranner of the Schranner Negotiation Institute and Sebastian Moritz from TWS Partners to celebrate the power of Game Theory in high stakes negotiations. We explore real-world negotiation cases, discuss the Game Theory perspective on successful strategies, and highlight how the two intersect to empower decision-makers. Join us as we reflect on 100 episodes of insights and celebrate the partnership between Schranner Negotiation Institute and TWS Partners!   Matthias Schranner is an FBI trained negotiation expert who together with his team at the Schranner Negotiation Institute advises business and government leaders around the globe in navigating high stakes situations. Sebastian Moritz is managing partner at TWS Partners and advises global executives and organizations on strategic negotiations, incentive systems, transformation, and sustainability, blending game theory expertise with a passion for innovation.    

In this episode, Topi Miettinen shares his view and research on insights from Game Theory on international conflicts. We start discussing different examples of conflicts, e.g.  complex negotiations within the EU and even war. Based on the examples Topi shares his research on the role of commitment to finding agreements. He also shares how his research extends from a bilateral negotiation (as in a war of two parties) situation to a multilateral situation (as in the EU).   Topi Miettinen is professor of economics at Hanken School of Economics and Helsinki Graduate School of Economics. His research focuses on behavioural and experimental economics, microeconomics, and game theory.  

In this episode, we discuss with our guest J. McKenzie Alexander evolutionary game theory and its applications. We start discussing different models from evolutionary game theory starting with the local interaction model and then moving to the replicator model. Based on that we then turn to applications in social theory especially when discussing proto-moral behaviour. J. McKenzie Alexander is Professor of Philosophy at the London School of Economics. His research explores the intersection of game theory, philosophy, and social theory. J. McKenzie Alexander has put together simulations of the discussed models on his homepage. Also, he is publishing a new book titled ‘The Open Society as an Enemy’.

In this episode, our guest Raymond Fisman explains to us the persistent challenge of corruption and the surprising ways in which political polarization and so called “wedge issues” help to sustain it. He shares his insights into why anti-corruption reforms remain elusive despite widespread public demand for honest governance and the creative measures some leaders have taken to battle corruption.  Raymond Fisman is the Slater Family Professor in Behavioral Economics at Boston University. His research explores the complex ways in which corruption and other informal behaviors influence markets, governance, and economic development.

In this episode, we explore the contributions of this year’s Nobel Prize laureates in Economics – Daron Acemoglu, Simon Johnson, and James Robinson – and their work on the role of institutions in shaping economic prosperity. Our guest, Navid Sabet guides us through their core findings and shares his perspective on their influential research and its impact on the field of political economy. Finally, he connects these insights to his own research, examining how institutions affect immigration reform and economic opportunities.   Navid Sabet is Assistant Professor in Economics at Goethe University Frankfurt. His research interests lie in the areas of political economy, applied microeconomics and public economics. Navid mentions the Nobel Prize winners’ famous paper from 2001, “The Colonial Origins of Comparative Development: An Empirical Investigation”. You can find it here. For more info on Navid’s research, you can check out his homepage or his paper on Immigrant legalization and the redistribution of state funds in the US.
