The cybernetics of nonzero sum games – the prisoner's dilemma reinterpreted as a pure conflict game with nature, with empirical applications
… sum 2-player games. When applied to 2-player prisoner’s dilemma games, the solution procedure assigns mixed strategies to the prisoners, thereby “resolving” the dilemma. The mixed strategies vary with the payoffs (up to a linear transformation). For prisoner’s dilemma matrices which have been …

Losses, gains, and asymmetry in the 1-shot prisoner's dilemma game
… are rarely studied in the context of the 1-shot prisoner’s dilemma (PD) game. Many real-world interactions, however, are 1-time events, so it is important to determine how well factors studied in iterated games apply to the 1-shot PD. In the present within-subject study we systematically examine …

Third-party imagined interactions: expanding imagined interactions as false memories in understanding interactions
… An experiment using an induced TPII, with a prisoner’s dilemma and an iterated chicken game was conducted to learn the effect of the TPII on plans to communicate. The research question found that TPIIs exist and are mostly similar to IIs in topics, imagined targets characteristics and …

Impacts of Corporate Social Responsibility on New Product Development
… that competing firms can become trapped in a prisoner’s dilemma, where both firms choose to offer competing SR products, even though it leads to a decline in profits for both. We further show how a high marginal cost for providing an SR product can lead to a quasi-monopoly situation, where one …

Achieving Robustness and Generalization in MARL for Sequential Social Dilemmas through Bilinear Value Networks
… gameplay strategies in sequential social dilemma (SSD) games. Recent literature has demonstrated that reward shaping can not only be used to enable MARL agents to discover diverse, human-interpretable strategies with emergent qualities, but also help alleviate the issue in conventional …

Essays in Behavioural and Experimental Economics
… repeated games. Using data from previous prisoner’s dilemma games and data from our own experiment, we assess subjects’ cooperation rates and show that realized match length of early matches has a significant impact on the cooperation rates of subsequent matches. We furthermore demonstrate …

Four Essays on Strategic Behavior, Empathy and Gender Differences in Voluntary Provision of Public Goods and Responsible Consumption
… how empathy works in an interactive multiperson prisoner’s dilemma game. Moreover, we analyse whether priming (that allows distinguishing between a conventional and a legal socially responsible product), has an impact on participants’ choices. We further explore the possibility that empathy acts …

Situational Affordances and Psychopathy: Examining Contextual Influences on Exploitative Behavior in Economic Games
… and psychopathy-success relationships in the Prisoner’s Dilemma Game. While the relationship between psychopathy and exploitation did not differ as a result of match length, the relationship between psychopathy and success was contingent on the length of interactions. The findings are …

Mitigating Social Dilemmas in Multi-Agent Reinforcement Learning with Formal Contracting

Essays on Economic Inequality and Social Capital
… the trust game, the stag-hunt game, and the prisoner’s dilemma. The results show that inequality weakens trustworthiness and coordination on efficient outcomes, even when participants face identical payoff structures. Trust is lower under merit-based inequality than under luck, despite merit …

Social interactions and the prisoner's dilemma game: new measures of cognitive and behavioral phenotypes
… a game-theoretic task for children, the Repeated Prisoner’s Dilemma (RPD), and demonstrated how it can be used to elucidate the mechanisms underlying children’s social interactions. I developed a novel RPD with fixed-strategy partners in order to test specific hypotheses based on developmental …

Behaviour in Common-Pool Resource games: investigating decision-making towards conservation and environmental issues
… to further analyse the dynamics found in social dilemmas such as Common-Pool Resources (CPRs). The game was an altered (with an amended matrix) version of a two-player Iterated Prisoner’s Dilemma, where players had to make consumption decisions regarding a general resource that had the …

User-centric power-friendly quality-based network selection strategy for heterogeneous wireless environments
… repeated cooperative game following the repeated Prisoner’s Dilemma game from Game Theory. It combines reputation-based systems, game theory and a network selection mechanism in order to create a reputation-based heterogeneous environment. In this environment, the users keep track of their …

Collective dynamics of evolving populations and their strategies with application to medicine
… for a wide variety of cooperative games of the prisoner’s dilemma type, cooperation eventually becomes the dominant strategy as long as the rules are permitted to evolve in response to the changing environment. Therefore, the ubiquitously observed cooperation in nature may come from stochastic …

Essays in Networks and Experimental Economics
… the repeated play of the ultimatum game and the prisoner’s dilemma. GPT is prompted to generate both its choices and reasoning. Results show that GPT's behaviour aligns with intuitive expectations and observed human behaviour in important aspects, such as offering non-trivial amounts, rejecting …
