A huge present for my small contribution at the Game Theory Summer School in Kyiv arrived today! 🎁 The school was jointly organised by the Kyiv School of Economics and the Ukrainian Catholic University. The main work was carried out by the local organisers, who put together an excellent programme 🙏

Some amazing work by @franzilesi.bsky.social on repeated games! In this new paper, she describes the conditions under which a player can remember less than their opponent and still achieve a best response. See 🧵👇 This is my first last-author publication! Feeling like a wise person already 🧙‍♂️

Cooperation in society: How our memory influences our behavior Conditional cooperation with longer memory 🏺🧪 www.pnas.org/doi/10.1073/... Direct reciprocity is based on repeated interactions. Nice strategies are never the first to defect which can sustain full cooperation as a Nash equilibrium.

Evolutionary dynamics of reactive-n strategies. To explore the evolutionary dynamics among reactive-n strategies, we run simulations based on the method of Imhof and Nowak (68). This method assumes rare mutations. Every time a mutant strategy appears, it goes extinct or fixes before the arrival of the next mutant strategy. (A and B) We run twenty independent simulations for reactive-n strategies and for reactive-n counting strategies. For each simulation, we record the most abundant strategy (the strategy that resisted most mutants). The respective average cooperation probabilities are in line with the conditions for partner strategies. (C and D) With additional simulations, we explore the average abundance of partner strategies and the population’s average cooperation rate. For a given resident strategy to be classified as a partner by our simulation, it needs to satisfy all inequalities in the respective characterization. In addition, it needs to cooperate after full cooperation with a probability of at least 95%. For all considered parameter values, we only observe high cooperation rates when partner strategies evolve. Simulations are based on a donation game with b = 1, c = 0.5, a selection strength β = 1, and a population size N = 100, unless noted otherwise. For n equal to 1 and 2, simulations are run for time steps. For n = 3 we use time steps.

There seem to be a lot of BlueSky users interested in evolutionary game theory and related areas of theoretical ecology and evolution. I made a preliminary starter pack for EGT and related topics. Please let me know if you would like to join or if you have any suggestions. go.bsky.app/N2SMwCN
