(WP 2019-01) Stratification Economics as an Economics of Exclusion

Stratification Economics (SE) is an emergent sub-field in economics, but its JEL classification misrepresents its content and its relationship to the whole of economics. This paper first develops a more accurate characterization of SE by identifying its differences with Mainstream Economics (ME), its commonalities with economics in a broad sense, and how the combination of these differences and commonalities define it as a distinct research program. It then applies this definition to an economic goods taxonomy that makes a distinction between local public goods and common pool goods to interpret SE’S distinct research program as an economics of exclusion. The paper closes with a discussion of how SE might explain socioeconomic change in social group identity terms
