Game Changer - the game theory podcast
TWS Partners
In Game Changer, the podcast by TWS Partners, we want to share our enthusiasm and passion for game theory and its applications.
We invite guests from business and academia to discuss how they use the power of game theory in their profession to make a difference – and to learn some fun anecdotes, useful facts and valuable insights along the way. Join us on this journey, and find out that game theory is much more than a topic for ivory tower discussions.

Putting your money where your mouth is – on commitment in auctions | with Vitali Gretschko
In this episode, Vitali Gretschko sheds some light on a fundamental game theoretic concept: Commitment. He explains why commitment is a crucial prerequisite of auctions and introduces different ways of generating commitment. We also explore how commitment is linked to the concept of information and discuss auction concepts which make it less likely for the auctioneer to break their commitment afterwards. Vitali Gretschko is Professor of Market Design at the University of Mannheim and head of the ZEW Research Department "Market Design". In the interview, Vitali mentions papers explaining how to use cryptography to create commitment in mechanism designs. You can find them here and here.

Auctions, bidding strategies and uncertainty | with Bernhard Kasberger
From selling on eBay over Google advertisements to buying a house, auctions are all around us! But what makes it so difficult to find the right bidding strategy? In this episode Bernhard Kasberger sheds some light on what a so called first price auction is, why it is challenging to "bid correctly" and what the recipe for the optimal bid strategy under maximum uncertainty is in theory. He explains how his findings apply to the real life and which additional related topics he is currently working on. Bernhard Kasberger currently works as a Postdoc at the Düsseldorf Institute for Competition Economics (DICE) at the Heinrich Heine University Düsseldorf. His research is focused on auctions, market design, industrial organization and game theory. The research Bernhard presents in the interview is detailed in this paper.

A dangerous game: On Geoengineering and moral hazard | with Gernot Wagner
In this episode Gernot Wagner explains the concept of Geoengineering and its potential role in preventing climate change. He analyses the implications of Geoengineering from a game theoretic perspective and shows the connection to the game theoretic concept of "moral hazard". He also gives some advice on how we can all profit from the (potential) advantages of Geoengineering (and other new technologies), without falling into the "moral hazard trap". Gernot Wagner is climate economist at Columbia Business School where his research is focused on climate risks and climate policy. He is also the author of many books about climate change and what to do against it, with "Geoengineering: the Gamble" being his latest one.

To share or not to share. Credit, incentives and competition among researchers | with Remco Heesen
To share or not to share. Credit, incentives and competition among researchers | with Remco Heesen In this episode Remco Heesen shares his insights on the trade-offs researchers face when deciding whether to share intermediate results with fellow researchers. He explains how incentive structures in research lead to a suboptimal outcome and gives historic examples of prominent researchers who have been subject to these incentives. Remco then discusses possible measures that can be taken to encourage researchers to share intermediate results with their colleagues. Remco Heesen currently works as a researcher and senior lecturer at the University of Western Australia and the University of Groningen. Starting September this year he will take on a position as Assistant Professor at the London School of Economics and Political Sciences in the Department of Philosophy, Logic and Scientific Method.

Why market designers love NFTs | with Scott Kominers
In this episode, Scott Kominers introduces us to the exciting world of NFTs. We learn about their fascinating properties and their potential for creating new markets or reshaping existing ones. Scott also gives a few practical examples of how NFTs can be used, both in the digital and the real world. Scott also gave us the idea of creating our very own NFT: We used the Proof of Attendance Protocol (POAP) to create a "digital badge or collectible" using blockchain technology. POAPs are typically used to digitally prove attendance of an event. In our case, we use them as a fun way to celebrate this Game Changer episode with our listeners. You can claim your very own POAP by contacting us via email at gamechanger@tws-partners.com. Scott Duke Kominers is Professor of Business Administration in the Entrepreneurial Management Unit at Harvard Business School, a Faculty Affiliate of the Harvard Department of Economics, and a Research Partner at a16z crypto. He also advises a number of companies on marketplace and incentive design, especially in the world of crypto and web3. He is co-authoring a book about NFTs.
