Hotelling’s metaphor of spatial competition on Main Street has become one of the most important models in understanding strategic product differentiation. A vast literature has evolved, discussing extensions of the model with respect to the nature of transport costs, distributions of consumers (or preferences), dimensions and so on.
Multi-stage games like the
Hotelling game are usually solved analytically by backward induction.
our paper adds to the literature by explicitly taking consumer attitudes
into account in a spatial competition model and by assessing the impact on
location choices made by firms. In order to do so, we translated
Hotelling’s model of spatial competition into an agent-based
model. Our agent based model is based on decision-rules that are
consistent with the concept of Nash equilibrium. The aim of the model is
to find the optimal location for a firm to be located, considering
the distribution of consumers. The empirical part of the paper focuses
on how consumer attitudes affect firms pricing and location decisions in
the context of spatial competition. The use of agent-based modeling allows
us to analyze consumer attitudes without having to impose continuous
demand functions − which is required when solving it analytically−,
thus greatly increasing our scope of analysis.
