Implementing an Agent Trade Server

An experimental server for stock trading autonomous agents is presented and made available, together with an agent shell for swift development. The server, written in Java, was implemented as proof-of-concept for an agent trade server for a real financial exchange.Comment: 14 pages, 7 figures, intended for B/W printin

On the need and use of models to explore the role of economic confidence:a survey.

Empirical studies suggest that consumption is more sensitive to current income than suggested under the permanent income hypothesis, which raises questions regarding expectations for future income, risk aversion, and the role of economic confidence measures. This report surveys a body of fundamental economic literature as well as burgeoning computational modeling methods to support efforts to better anticipate cascading economic responses to terrorist threats and attacks. This is a three part survey to support the incorporation of models of economic confidence into agent-based microeconomic simulations. We first review broad underlying economic principles related to this topic. We then review the economic principle of confidence and related empirical studies. Finally, we provide a brief survey of efforts and publications related to agent-based economic simulation

Modelado y simulación de la evolución de valores en sociedades humanas con agentes software

El proyecto aborda, desde una perspectiva multidisciplinar, la integración de métodos y herramientas de los campos de la ingeniería del software, la inteligencia artificial y la sociología. Así, se pretende simular la complejidad de las sociedades humanas desde el diseño de un modelo sociológico. Este modelo tratará de simplificar la realidad extrayendo las características relevantes para el problema objeto de estudio. La simulación social implementará, según las líneas establecidas por dicho modelo, un sistema multiagente en un entorno cerrado. La evaluación del sistema se realizará comparando sus resultados con los datos extraídos de encuestas reales. Se ha experimentado también con otras técnicas de inteligencia artificial, obteniendo distintos módulos de ampliación del sistema: lógica borrosa y salida en lenguaje natural. Esta memoria se complementa con los artículos realizados sobre este proyecto, que se adjuntan al final de la misma

Agent-based social simulation in markets

We show that certain desired behavioural properties of agent-based models can be deterministically induced by anappropriate mathematical structure. We also point out problems related to the handling of parameters, and of the modelling of time, in agent-based models. Our purpose is to illustrate some problems of agentbased social simulations in markets, as a rst step towards the more ambitious goal of providing a methodology for such simulations. 1
