Inequality of Opportunity and Stratification Economics: Different Paths, Shared Concerns

Abstract

This paper compares two approaches to the study of inequality that have recently consolidated as distinct fields: the economics of inequality of opportunity (IOp) and stratification economics (SE). IOp examines how circumstances beyond individual control shape inequalities, while SE emphasizes how institutions and group identities reproduce intergroup hierarchies. I argue that, despite distinct origins, the two frameworks can be viewed as complementary. To support this claim, I outline the main features of each theoretical framework and contrast them along several dimensions: their equalisandum, the role of social groups, primary unit of analysis, and their conception of how structural factors influence inequality. The analysis shows that the distance between the two approaches is less significant than often assumed. Their differences enhance their complementarity, positioning SE and IOp not as competitors but as mutually reinforcing frameworks for understanding inequality.
