Abstract

Inequality at the top is on the rise, and labour income is a progressively larger contributor to concentration at the top. This paper investigates top earnings inequality in South Africa from a sectoral and firm-level perspective, using matched employer-employee administrative data. We also propose a method for decomposing top shares in within-groups and between-groups components.
