It is utilized in economics to understand the economic behaviours, such as behaviours of consumers, markets and firms. Game theory has been commonly used in social sciences as well. It is applied in the study of sociological, political and psychological behaviours. WebJul 6, 2024 · We also show that a core is formed over several rounds of repeated PD game. This core acquires a symmetric structure. It is due to the symmetric strategy of the pairs of core players in the repeated PD game. This core is relatively stable over time, both in its size and in the many structural properties resulting from the core-periphery dichotomy. matthias gorny site
