Artificial consumer societies in risky markets - the case of food scares and information release strategies — •Volker Saggau — Institut für Agrarökonomie, Uni Kiel, Olshausenstr. 40, 24098 Kiel

Our motivation is lying on the question How does a food scare and information of a food scare influence the buying decision of one single agent and the aggregate demand?. Since we investigate a society of consumers which do have their own decision functions, we can observe how new information could influence the behaviour of each consumer and more interesting the aggregate changes in the demand by creating a population of agents. This multiagent simulation can be used to investigate how different information releases and decision functions influence the aggregate demand. Our intention is to measure how different information strategies influence the aggregate demand. For this purpose we use a multiagent method in order to follow a bottom up approach where each agent acts individually. The interaction between the agents leads to an emergence of an aggregate demand that comes from the bottom up. Each agent follows its internal updating and decision algorithms so that on the aggregate level the demand changes according to the outcomes of the interaction and its related updating processes. After the communication phases the aggregation of the outcomes of each agent shows the result of the information strategy that was selected.
