"Agent-Based Approaches in Economic and Social Complex Systems VIII" is a specialized book that focuses on the application of agent-based models and simulations for the analysis of complex social and economic systems. This innovative method allows for the examination of social phenomena from a bottom-up perspective and is applied across various disciplines, including economics, management, sociology, and politics, as well as in engineering fields related to social activities. The book features a selection of 13 carefully chosen contributions presented at the eighth International Workshop on agent-based approaches in economic and social complex systems. The contributions provide valuable insights into current research findings and methods of agent-based modeling and simulation.
