Complex Systems


My main research focus is the interconnection between Complex Systems and Economics: trying to understand dynamic economic issues through systems simulations and networks.

I’m also interested in complex urban systems models and their integration with Input-Output models for disaster analysis.

    Abstract: Due to limitations on resources availability, agents have to decide how to transform, distribute and consume inputs in order to attend society’s needs. This is the primary focus of microeconomics: how efficiently allocate scarce resources between alternative ends. To accomplish this goal, economic theory relies on models which have several simplifications regarding human behavior in order to apprehend and analyze the economic dynamics and forecast its implications. Neoclassical School postulates strong hypothesis about motivations and interactions of economic agents. These are source of several criticisms from other economic schools and psychologists who do not find parallels between idealized neoclassic economic agents and empirical behavioral patterns. Hence, this study seeks to integrate psychological aspects of human behavior into economic analysis through agent based modeling. It is proposed a simulation model based on complexity theory in order to analyze market price formation and fluctuation, and in which way different cognitive mechanisms can affect its dynamics.
