This paper shows how Rule Based Fuzzy Cognitive Maps can be useful to model qualitative socio-economic systems, by discussing and presenting a macroeconomic model that, although developed eight years ago and based on simple qualitative rules, described and predicted the current economic crisis when the policy behavior of the banking system regarding tax-rates was assumed similar to the one that...

We formulate the problem of computing time in discrete dynamical agent-based models in the context of socio-economic modeling. For such formulation, we outline a simple solution. This requires minimal extensions of the original untimed model. The proposed solution relies on the notion of agent-specific schedules of action and on two modeling assumptions. These are fulfilled by most models of pr...

Collective behavior of the complex socio-economic systems is heavily influenced by the herding, group, behavior of individuals. The importance of the herding behaviormay enable the control of the collective behavior of the individuals. In this contribution we consider a simple agent-based herding model modified to include agents with controlled state. We show that in certain case even the small...

We examine the role of information-based measures in detecting and analysing phase transitions. We contend that phase transitions have a general character, visible in transitions in systems as diverse as classical flocking models, human expertise, and social networks. Information-based measures such as mutual information and transfer entropy are particularly suited to detecting the change in sc...

The SEDO project develops a platform combining fast access, user freedom, and coherence of the results for presenting complex socio-economic data. As an initial yield, this joint project involving two research actors of Luxembourg, the CEPS/INSTEAD for the content and the CRP-Gabriel Lippman for the technical realization, will deliver on the Net the results of longitudinal surveys about the lif...

political legitimacy is one of the fundamental notions in contemporary political theorizing. to explain this notion, a set of views, influenced by weber, put emphasis on the role of political beliefs of the citizens. yet, recent academic enterprises refer to the political agents, focusing on their actions. this article studies iranians’ socio-economic conditions in 1990’s, and reveals the setti...
