【摘要】The paper proposes an empirical framework for measuring competitive interactionsbetween pairs of ?rms in a certain industry characterized by spatially differentiated ?rms andheterogeneity in consumer tastes. Recognizing that the degree of competition between ?rmsdepends on the extent to which a representative consumer switches among ?rms, the frameworkis built on the Latent Class Logit model and on consumer choice histories. It emphasizes thespatial dimension of competition, provides a disaggregated measure of demand contestability,and proposes a network-based model of supplier competition using a new Global PairwiseCompetition Index.
