Structural Analysis of a Consumption-Based Stratification Indicator: Relational Proximity of Household Expenditures

摘要

This paper proposes a new analysis of consumption inequality using relational methods, derived from network images of social structure. We combine structural analysis with theoretical concerns in consumer research to propose a relational theory of consumption space, to construct a stratification indicator, and to demonstrate its analytical efficacy with aggregate consumption data. This allows us to emphasize the multi-dimensionality of the relationship between social groups and consumption patterns in the context of a stratification perspective. We utilize the concept of structural equivalence, derived from network models of social structure, to recover relational proximity between social groups and between consumption categories. Additionally, we use relational proximity to construct a new indicator of consumption hierarchy and we test its predictive ability in estimating consumption behavior. We discuss the theoretical implications of our findings for a spatial theory of stratification, as well as possible directions for future research.
