Agent Based Models of Language Competition: Macroscopic descriptions and Order-Disorder transitions

We investigate the dynamics of two agent based models of language competition. In the first model, each individual can be in one of two possible states, either using language X or language Y , while the second model incorporates a third state XY , representing individuals that use both languages (bilinguals). We analyze the models on complex networks and two-dimensional square lattices by analy...

Agent-based models and industrial organization theory. A price-competition algorithm for agent-based models based on Game Theory

Purpose: Simulating markets using agent‐based models must consider pricing. How‐ ever, the strategic nature of prices limits the development of agent‐based models with endogenous price competition. Methods: I propose an agent‐based algorithm based on Game Theory that allows us to simulate the pricing in different markets. I test the algorithm in five theoretical economic models from the industr...

Inferring Equation-Based Models from Agent-Based Models: A Case Study in Competition Dynamics

Two types of model, equation-based models (EBMs) and agentbased models (ABMs) are now widely used in modeling ecological complex systems and seem not to be reconciled. While ABMs can help in exploring and explaining the local causes of global phenomena, EBMs are useful for predicting their long-term evolution without having to explore them through simulated experiments. In this paper, we show t...

Population and Agent Based Models for Language Convergence

Adaptive agents cooperating in rich, open environments will need shared ontologies and linguistic conventions to communicate critical information. In the face of open systems and environmental change, pre-defined ontologies are suboptimal. In open systems, new agents or web services can require new conventions not captured in existing conceptualizations. A more adaptive and more theoretically i...
