Abstract

In this paper, we propose using a mixed genetic-floyd-warshall algorithm in combination with a Floyd-warshall algorithm to model the satisficing behaviour of consumers across spatially differentiated stores. Consumer agents can pick a basket of goods from different stores to either maximize their utility or to "satisfice" by selecting the first basket with a utility that is higher than their satisfaction threshold. The Floyd-warshall algorithm is used to find the shortest path between two chosen stores by considering travel cost. Factors such as price, quality of goods, the cost of travel to the store, consumers' decision-making preferences, and store locations play significant roles in the decision-making process of consumer agents. The model is tested based on mechanisms at the individual level to show how the model works and at the macro-level to reproduce foundational theories in economics. [ABSTRACT FROM AUTHOR]

Abstract

International audience; We consider a simple model of agents that have an opinion about themselves, about the group they belong to and about the other agents and their group. During random pair interactions, the agents modify their opinions about themselves, about their group, about the other agent and about her group and possibly about some other agents and their group (if there are gossips in the model). We assume that in the discussions, the agents do not tell directly their opinions about the agents and themselves, but a weighted average of this opinion and their group opinion. This aims at modelling socially expected behaviours that take into account the group status of an agent when talking about her (even when the agent talks about herself). Starting from neutral opinions about groups and agents, we observe the emergence of group hierarchies when gossips are activated in the model while there is none otherwise.
